# ABSTRACT

Aryacoin is a new cryptocurrency, which allows for decentralized, peer to peer transactions of electronic cash. It is like Bitcoin and Litecoin, but the trading of the coin occurs on sales platforms that have no restriction to use. Further, it was created with the goal of addressing the double spend issues of Bitcoin and does so using a timestamp server to verify transactions. It works by taking the hash of a block of items to be timestamped and widely publishing the hash. The timestamp proves that the data must have existed at the time in order to get the hash. Each timestamp then includes the previous timestamp in its hash, forming a chain.
The Aryacoin team is continuously developing new use cases for the coin, including exchanges where users can exchange the coins without any fees or restrictions, and offline options where the coins can be bought and sold for cash. The coins can also be used on the company’s other platform, mrdigicoin.io. Along with the coin, there is a digital wallet that can be created and controlled by the user entirely, with no control being retained by the Aryacoin team.

# 1.INTRODUCTION

The concept of Blockchain first came to fame in October 2008, as part of a proposal for Bitcoin, with the aim to create P2P money without banks. Bitcoin introduced a novel solution to the age-old human problem of trust. The underlying blockchain technology allows us to trust the outputs of the system without trusting any actor within it. People and institutions who do not know or trust each other, reside in different countries, are subject to different jurisdictions, and who have no legally binding agreements with each other, can now interact over the Internet without the need for trusted third parties like banks, Internet platforms, or other types of clearing institutions.
When bitcoin was launched it was revolutionary allowing people to transfer money to anytime and anywhere with very low transaction fees . It was decentralized and their is no third party involved in the transaction , only the sender and receiver were involved.
This paper provide a solution to the double-spending problem using a peer-to-peer distributed timestamp server to generate computational proof of the chronological order of transactions.The system is secure as long as honest nodes collectively control more CPU power than any cooperating group of attacker nodes. Bitcoin was made so that it would not be controlled or regulated but now exchanges and governments are regulating bitcoin and other cryptocurrencies at every step. Aryacoin was developed to overcome these restrictions on a free currency.
Aryacoin is a new age cryptocurrency, which withholds the original principle on which the concept of cryptocurrency was established. Combining the best in blockchain technology since the time of its creation, Aryacoin strives to deliver the highest trading and mining standards for its community.

Aryacoin is a new age cryptocurrency, which withholds the original principle on which the concept of cryptocurrency was established. Combining the best in blockchain technology since the time of its creation, Aryacoin strives to deliver the highest trading and mining standards for its community.
Aryacoin is a blockchain based project that allows users to access their wallet on the web and mobile browsers, using their login details.
Aryacoin can be mined; it also can be exchanged by other digital currencies in several world-famous exchanges such as Hitbtc, CoinEx, P2pb2b, WhiteBit, Changelly and is also listed in reputable wallets such as Coinomi and Guarda.
Aryacoin is a coin, which can be used by anyone looking to use cryptocurrency which allows them to keep their privacy even when buying/selling the coin along with while using the coin during transactions. Proof of work and cryptographic hashes allows transactions to verified.
Stable Fee Per AYA is a unique feature of Aryacoin, so by increasing the amount or volume of the transaction, there is no change in the fee within the network, which means that the fee for sending an amount less than 1 AYA is equal to several hundred million AYA. Another unique feature of Aryacoin is the undetectability of transactions in Explorer, such as the DASH and Monero, of course, this operation is unique to Aryacoin.
Using Aryacoin digital currency, like other currencies, international transactions can be done very quickly and there are no limitations in this area as the creators claim.
Aryacoin aims to allow users to access the Aryacoin wallet via the web and mobile browsers using their login details.
Aryacoin is a peer-to-peer electronic cash system that enables users to send and receive payments directly from one party to another, and allow them to transfer funds across borders with no restriction or third party involvement. The blockchain-based system embraces the digital signature, which prevents double spending and low transfer fees, which enables users to transfer huge amounts with very low fees. The proof-of-work consensus mechanism allows each transaction to be verified and confirmed, while anonymity enables users to use the coin anywhere at any time.
According to the website of the operation, each wallet is divided into 2 or more AYA wallet addresses for each transaction, and depending on the volume of the transaction block, the origin, and destination of transactions in the network can not be traced and displayed to the public.
In fact, each wallet in Aryacoin consists of a total of several wallets. The number of these wallets increases per transaction to increase both security and privacy. Aryacoin also uses the dPoW protocol. In the dPoW protocol, a second layer is added to the network to verify transactions, which makes “51% attack” impossible even with more than half of the network hash, and blocks whose Blockchain uses this second layer of security never run the risk of 51% attacks.
AYA has been listed on a number of crypto exchanges, unlike other main cryptocurrencies, it cannot be directly purchased with fiats money. However, You can still easily buy this coin by
first buying Bitcoin from any large exchanges and then transfer to the exchange that offers to trade this coin.

## 1.1.1 ARYACOIN HISTORY

Aryacoin (AYA) is a new cryptocurrency, which has been created by a group of Iranian developers, is an altcoin which allows for decentralised, peer to peer transactions of electronic cash without any fees whatsoever. Along with the coin, there is a digital wallet that can be created and managed by the user entirely, with no control being retained by the Aryacoin team.
Aryacoin’s founder, Kiumars Parsa, has been a fan of alternative currencies and particularly Bitcoin.
We see people from all around the world using Blockchain technology and the great benefits that came with it and it then that I decided to solve this puzzle for find a way of bringing the last missing piece to the jigsaw. The idea for Aryacoin was born.” Parsa said.
Parsa and his team of Iranian ex-pats not only persevered but expedited the project and just a year later, in the summer of 2019, the first version of Aryacoin was released. In 2020, Aryacoin is the first and only Iranian coin listed on CMC.
Parsa goes on to state that it is now the strength of the community that has invested in the coin that will ultimately drive its success, alongside its robust technology and appealing 0% network fees.
We have thousands of voices behind Aryacoin. People for the people make this coin. It is a massive shout out for democracy. This had made us base the whole team strategy on the benefits for both our users and our traders.
One key example is that the network fee on AYA Blockchain is 0%. Yes, absolutely nothing, which which differentiates us from other networks. What also differentiates us from other coins is that we have AYAPAY which is the first cryptocurrency Gateway in the world which does not save funds on third party storage with all funds being forwarded directly to any wallet address that the Gateway owner requests”.
So for the first time ever, and unlike other gateways, incoming funds will be saved on the users account with submitted withdrawal requests then made on the Gateway host website. In AYAPAY which has also been developed by the Aryacoin team, all funds without extra fees or extra costs will directly forwarded to users wallets. We have named this technology as CloudWithdrawal.
We are continuously challenging ourselves as it is a crowded marketplace. We are striving to have a safer Blockchain against 51% attacks, faster confirmations speeds of transactions, cheaper network fee, growing the market by cooperation with Top tier Exchangers.

## 1.1.2 ARYACOIN’S MAIN GOAL

Aryacoin’s main goal is to educate people and give them the freedom to use cryptocurrency in any way they want. Aryacoin empowers the users to transfer, pay, trade cryptocurrency from any country around the globe.
Platforms that have been created by Aryacoin Team, as well as those that will go live in future, operate on the same principle and exclude absolutely no one.

## 1.1.3 PROBLEM ARYACOIN SEEKS TO SOLVE

Aryacoin aims to provide a long-term solution to the problem of double spending, which is still common in the crypto market. The developers of the system have created a peer-to-peer distributed timestamp server that generates computational proof of the transactions as they occur.
Besides, the system remains secure provided honest nodes control more CPU power than any cooperating group of attacker nodes. While Bitcoin was designed not to be regulated or controlled, many exchanges and governments have put regulatory measures on the pioneer cryptocurrency at every step. Aryacoin aims to overcome these restrictions as a free digital currency.

## 1.1.4 BENEFITS OF USING ARYACOIN

Aryacoin solution offers the following benefits:
• Real-time update: whether you’re going on a holiday or a business trip, no problem. You can access your coins all over the world.
• Instant operations: Aryacoin makes it quite easy for you to use your digital wallet and perform various operations with it.
• Safe and secure: all your data is stored encrypted and can only be decrypted with your private key, seed, or password.
• Strong security: The system has no control over your wallet. You are 100% in charge of your wallet and funds.

## 1.1.5 ARYACOIN FEATURES

1. Anonymity
The coin provides decent level of anonymity for all its users. The users can send their transactions to any of the public nodes to be broadcasted , the transaction sent to the nodes should be signed by the private key of the sender address . This allows the users to use the coin anywhere any time , sending transactions directly to the node allows users from any place and country .
2. Real Life Usage
aryacoin’s team is continuously developing new and innovative ways to use the coins , they are currently developing exchanges where the users can exchange the coins without any fees and any restrictions . They also are currently developing other innovative technologies, which would allow users to spend our coins everywhere and anywhere.
3. Offline Exchanges
They are also working with different offline vendors which would enable them to buy and sell the coins directly to our users on a fixed/variable price this would allow easy buy/sell directly using cash . This would allow the coins to be accessible to users without any restrictions which most of the online exchanges have, also increase the value and number of users along with new ways to spend the coin. This would increase anonymity level of the
coin. In addition, introduce new users into the cryptomarket and technology. Creating a revolution, which educates people about crypto and introduce them to the crypto world, which introduces a completely new group of people into crypto and a move towards a Decentralized future!
4. Transactions
When it comes to transactions, Aryacoin embraces a chain of digital signatures, where each owner simply transfers the coin to the next person by digitally signing a hash of the previous transaction and the public key of the next owner. The recipient can then verify the signatures to confirm the chain of ownership. Importantly, Aryacoin comes with a trusted central authority that checks every transaction for double spending.
Aryacoin is the first and only Iranian digital currency that managed to obtain a trading license in other countries.
In collaboration with the foundation and financial giant Simplex, a major cryptocurrency company that has large companies such as Binance, P2P, Changelly, etc. Aryacoin has been licensed to enter the world’s major exchanges, as well as the possibility of purchasing AYA through Credit Cards, which will begin in the second half of 2020.
Also, the possibility of purchasing Aryacoin through Visa and MasterCard credit cards will be activated simultaneously inside the Aryacoin site. plus, in less than a year, AYA will be placed next to big names such as CoinCapMarket, Coinomi, P2P, Coinpayments and many other world-class brands today.

## 1.1.6 WHY CHOOSE ARYACOIN?

If you want to use a cryptocurrency that allows you to keep your privacy online even when buying and selling the coins, the Aryacoin team claims that AYA is the way to go. Aryacoin is putting in the work: with more ways to buy and sell, and fixing the issues that were present in the original Bitcoin, plus pushing the boundaries with innovative solutions in cryptocurrencies. You can get started using Aryacoin (AYA) payments simply by having a CoinPayments account!

## 1.1.7 ARYANA CENTRALIZED EXCHANGE

Aryana, the first Iranian exchange is a unique platform with the following features:
• The first real international Persian exchange that obtains international licenses and is listed in CoinMarketCap.
• The first Iranian exchange that has been cooperating with a legal and European exchange for 3 years.
• The possibility of trading in Tomans (available currency in Iran) at the user’s desired price and getting rid of the transaction prices imposed by domestic sites inside Iran.
• There is an internal fee payment plan by Iranian domestic banks for depositing and withdrawing Tomans for Aryacoin holders in Aryana Exchange.
• The number that you see on the monitor and in your account will be equal to the number that is transferred to your bank account without a difference of one Rial.
• The last but not least, noting the fact that there is a trading in Tomans possibility in Aryana exchange.
Aryana Exchange is using the most powerful, fastest, and most expensive server in the world, Google Cloud Platform (GCP), which is currently the highest quality server for an Iranian site, so that professional traders do not lag behind the market even for a second.
The feature of Smart Trading Robots is one of the most powerful features for digital currency traders. Digital cryptocurrency traders are well aware of how much they will benefit from smart trading robots. In the Aryana exchange, it is possible to connect exchange user accounts to intelligent trading bots and trade even when they are offline.
The injection of $1 million a day in liquidity by the WhiteBite exchange to maintain and support the price of Tether and eliminate the Tether fluctuations with Bitcoin instabilities used by profiteers to become a matter of course. ## 1.1.8 HOW DOES ARYACOIN WORK? Aryacoin (AYA) tries to ensure a high level of security and privacy. The team has made sure to eliminate any trading restrictions for the network users: no verification is required to carry out transactions on AYA, making the project truly anonymous, decentralized, and giving it a real use in day-to-day life. The Delayed-Proof-of-Work (dPoW) algorithm makes the Aryacoin blockchain immune to any attempts of a 51% attack. AYA defines a coin as a chain of digital signatures — each owner transfers the coin to the next owner by digitally signing the hash of the previous transaction and the public key of the next owner, and the receiver verifies the signatures and the chain of ownership. # 2. ARYACOIN TECHNOLOGY ## 2.1 PROOF-OF-WORK They use a proof-of-work system similar to Adam Back’s Hashcash to implement a distributed timestamp server on a peer-to-peer basis, rather than newspaper or Usenet publications. The proof-of-work involves scanning for a value that when hashed, such as with SHA-256, the hash begins with a number of zero bits. The average work required is exponential in the number of zero bits required and can be verified by executing a single hash. For their timestamp network, they implement the proof-of-work by incrementing a nonce in the block until a value is found that gives the block’s hash the required zero bits. Once the CPU effort has been expended to make it satisfy the proof-of-work, the block cannot be changed without redoing the work. As later blocks are chained after it, the work to change the block would include redoing all the blocks after it. The proof-of-work also solves the problem of determining representation in majority decision making. If the majority were based on one-IP-address-one-vote, it could be subverted by anyone able to allocate many IPs. Proof-of-work is essentially one-CPU-one-vote. The majority decision is represented by the longest chain, which has the greatest proof-of-work effort invested in it. If honest nodes control a majority of CPU power, the honest chain will grow the fastest and outpace any competing chains. To modify a past block, an attacker would have to redo the proof-of-work of the block and all blocks after it, then catch up with, and surpass the work of the honest nodes. ## 2.2 NETWORK The steps to run the network are as follows: • New transactions are broadcast to all nodes. • Each node collects new transactions into a block. • Each node works on finding a difficult proof-of-work for its block. • When a node finds a proof-of-work, it broadcasts the block to all nodes. • Nodes accept the block only if all transactions in it are valid and not already spent. This is a very simple system that makes the network fast and scalable, while also providing a decent level of anonymity for all users. Users can send their transactions to any of the public nodes to be broadcast, and the private key of the sender’s address should sign any transaction sent to the nodes. This way, all transaction info remains strictly confidential. It also allows users to send transactions directly to the node from any place at any time and allows the transferring of huge amounts with very low fees. ## 2.3 AYAPAY PAYMENT SERVICES GATEWAY: According to creators Aryacoin, the development team has succeeded in inventing a new blockchain technology for the first time in the world, which is undoubtedly a big step and great news for all digital currency enthusiasts around the world. This new technology has been implemented on the Aryacoin AYAPAY platform and was unveiled on October 2. AYAPAY payment platform is the only payment gateway in the world that does not save money in users’ accounts and transfers incoming coins directly to any wallet address requested by the gateway owner without any additional transaction or fee. In other similar systems or even systems such as PayPal, money is stored in the user account. ## 2.4 CONSENSUS ALGORITHM IN ARYACOIN The devs introduced the Delayed-Proof-of-Work (dPoW) algorithm, which represents a hybrid consensus method that allows one blockchain to take advantage of the security provided by the hashing power of another blockchain. The AYA blockchain works on dPoW and can use such consensus methods as Proof-of-Work (PoW) or Proof-of-Stake (PoS) and join to any desired PoW blockchain. The main purpose of this is to allow the blockchain to continue operating without notary nodes on the basis of its original consensus method. In this situation, additional security will no longer be provided through the attached blockchain, but this is not a particularly significant problem. dPoW can improve the security level and reduce energy consumption for any blockchain. ## 2.5 DOUBLE-SPEND PROBLEM AND SOLUTION One of the main problems in the blockchain world is that a receiver is unable to verify whether or not one of the senders did not double-spend. Aryacoin provides the solution, and has established a trusted central authority, or mint, that checks every transaction for double-spending. Only the mint can issue a new coin and all the coins issued directly from the mint are trusted and cannot be double-spent. However, such a system cannot therefore be fully decentralized because it depends on the company running the mint, similar to a bank. Aryacoin implements a scheme where the receiver knows that the previous owners did not sign any earlier transactions. The mint is aware of all transactions including which of them arrived first. The developers used an interesting solution called the Timestamp Server, which works by taking a hash of a block of items to be ‘timestamped’ and publishing the hash. Each timestamp includes the previous timestamp in its hash, forming a chain. To modify a block, an attacker would have to redo the proof-of-work of all previous blocks, then catch up with, and surpass the work of the honest nodes. This is almost impossible, and makes the network processes more secure. The proof-of-work difficulty varies according to circumstances. Such an approach ensures reliability and high throughput. # 3.

And guess what, Iran subsidizes electricity for bitcoin mining. mic drop submitted by iBrickedIt to Bitcoin [link] [comments] ##### Syscoin Platform’s Great Reddit Scaling Bake-off Proposal https://preview.redd.it/rqt2dldyg8e51.jpg?width=1044&format=pjpg&auto=webp&s=777ae9d4fbbb54c3540682b72700fc4ba3de0a44 We are excited to participate and present Syscoin Platform's ideal characteristics and capabilities towards a well-rounded Reddit Community Points solution! Our scaling solution for Reddit Community Points involves 2-way peg interoperability with Ethereum. This will provide a scalable token layer built specifically for speed and high volumes of simple value transfers at a very low cost, while providing sovereign ownership and onchain finality. Token transfers scale by taking advantage of a globally sorting mempool that provides for probabilistically secure assumptions of “as good as settled”. The opportunity here for token receivers is to have an app-layer interactivity on the speed/security tradeoff (99.9999% assurance within 10 seconds). We call this Z-DAG, and it achieves high-throughput across a mesh network topology presently composed of about 2,000 geographically dispersed full-nodes. Similar to Bitcoin, however, these nodes are incentivized to run full-nodes for the benefit of network security, through a bonded validator scheme. These nodes do not participate in the consensus of transactions or block validation any differently than other nodes and therefore do not degrade the security model of Bitcoin’s validate first then trust, across every node. Each token transfer settles on-chain. The protocol follows Bitcoin core policies so it has adequate code coverage and protocol hardening to be qualified as production quality software. It shares a significant portion of Bitcoin’s own hashpower through merged-mining. This platform as a whole can serve token microtransactions, larger settlements, and store-of-value in an ideal fashion, providing probabilistic scalability whilst remaining decentralized according to Bitcoin design. It is accessible to ERC-20 via a permissionless and trust-minimized bridge that works in both directions. The bridge and token platform are currently available on the Syscoin mainnet. This has been gaining recent attention for use by loyalty point programs and stablecoins such as Binance USD. # Solutions Syscoin Foundation identified a few paths for Reddit to leverage this infrastructure, each with trade-offs. The first provides the most cost-savings and scaling benefits at some sacrifice of token autonomy. The second offers more preservation of autonomy with a more narrow scope of cost savings than the first option, but savings even so. The third introduces more complexity than the previous two yet provides the most overall benefits. We consider the third as most viable as it enables Reddit to benefit even while retaining existing smart contract functionality. We will focus on the third option, and include the first two for good measure. 1. Distribution, burns and user-to-user transfers of Reddit Points are entirely carried out on the Syscoin network. This full-on approach to utilizing the Syscoin network provides the most scalability and transaction cost benefits of these scenarios. The tradeoff here is distribution and subscription handling likely migrating away from smart contracts into the application layer. 2. The Reddit Community Points ecosystem can continue to use existing smart contracts as they are used today on the Ethereum mainchain. Users migrate a portion of their tokens to Syscoin, the scaling network, to gain much lower fees, scalability, and a proven base layer, without sacrificing sovereign ownership. They would use Syscoin for user-to-user transfers. Tips redeemable in ten seconds or less, a high-throughput relay network, and onchain settlement at a block target of 60 seconds. 3. Integration between Matic Network and Syscoin Platform - similar to Syscoin’s current integration with Ethereum - will provide Reddit Community Points with EVM scalability (including the Memberships ERC777 operator) on the Matic side, and performant simple value transfers, robust decentralized security, and sovereign store-of-value on the Syscoin side. It’s “the best of both worlds”. The trade-off is more complex interoperability. # Syscoin + Matic Integration Matic and Blockchain Foundry Inc, the public company formed by the founders of Syscoin, recently entered a partnership for joint research and business development initiatives. This is ideal for all parties as Matic Network and Syscoin Platform provide complementary utility. Syscoin offers characteristics for sovereign ownership and security based on Bitcoin’s time-tested model, and shares a significant portion of Bitcoin’s own hashpower. Syscoin’s focus is on secure and scalable simple value transfers, trust-minimized interoperability, and opt-in regulatory compliance for tokenized assets rather than scalability for smart contract execution. On the other hand, Matic Network can provide scalable EVM for smart contract execution. Reddit Community Points can benefit from both. Syscoin + Matic integration is actively being explored by both teams, as it is helpful to Reddit, Ethereum, and the industry as a whole. # Proving Performance & Cost Savings Our POC focuses on 100,000 on-chain settlements of token transfers on the Syscoin Core blockchain. Transfers and burns perform equally with Syscoin. For POCs related to smart contracts (subscriptions, etc), refer to the Matic Network proposal. On-chain settlement of 100k transactions was accomplished within roughly twelve minutes, well-exceeding Reddit’s expectation of five days. This was performed using six full-nodes operating on compute-optimized AWS c4.2xlarge instances which were geographically distributed (Virginia, London, Sao Paulo Brazil, Oregon, Singapore, Germany). A higher quantity of settlements could be reached within the same time-frame with more broadcasting nodes involved, or using hosts with more resources for faster execution of the process. Addresses used: 100,014 The demonstration was executed using this tool. The results can be seen in the following blocks: 612722: https://sys1.bcfn.ca/block/6d47796d043bb4c508d29123e6ae81b051f5e0aaef849f253c8f3a6942a022ce 612723: https://sys1.bcfn.ca/block/8e2077f743461b90f80b4bef502f564933a8e04de97972901f3d65cfadcf1faf 612724: https://sys1.bcfn.ca/block/205436d25b1b499fce44c29567c5c807beaca915b83cc9f3c35b0d76dbb11f6e 612725: https://sys1.bcfn.ca/block/776d1b1a0f90f655a6bbdf559ff5072459cbdc5682d7615ff4b78c00babdc237 612726: https://sys1.bcfn.ca/block/de4df0994253742a1ac8ac9eec8d2a8c8b0a6d72c53d6f3caa29bb6c171b0a6b 612727: https://sys1.bcfn.ca/block/e5e167c52a9decb313fbaadf49a5e34cb490f8084f642a850385476d4ef10d70 612728: https://sys1.bcfn.ca/block/ab64d989edc71890e7b5b8491c20e9a27520dc45a5f7c776d3dae79057f59fe7 612729: https://sys1.bcfn.ca/block/5e8b7ecd0e36f99d07e4ea6e135fc952bf7ec30164ab6f4d1e98b0f2d405df6d 612730: https://sys1.bcfn.ca/block/d395df3d31dde60bbb0bece6bd5b358297da878f0beb96be389e5f0e043580a3 It is important to note that this POC is not focused on Z-DAG. The performance of Z-DAG has been benchmarked within realistic network conditions: Whiteblock’s audit is publicly available. Network latency tests showed an average TPS around 15k with burst capacity up to 61k. Zero-latency control group exhibited ~150k TPS. Mainnet testing of the Z-DAG network is achievable and will require further coordination and additional resources. Even further optimizations are expected in the upcoming Syscoin Core release which will implement a UTXO model for our token layer bringing further efficiency as well as open the door to additional scaling technology currently under research by our team and academic partners. At present our token layer is account-based, similar to Ethereum. Opt-in compliance structures will also be introduced soon which will offer some positive performance characteristics as well. It makes the most sense to implement these optimizations before performing another benchmark for Z-DAG, especially on the mainnet considering the resources required to stress-test this network. ## Cost Savings Total cost for these 100k transactions:$0.63 USD
See the live fee comparison for savings estimation between transactions on Ethereum and Syscoin. Below is a snapshot at time of writing:
ETH price: $318.55 ETH gas price: 55.00 Gwei ($0.37)
Syscoin price: $0.11 Snapshot of live fee comparison chart Z-DAG provides a more efficient fee-market. A typical Z-DAG transaction costs 0.0000582 SYS. Tokens can be safely redeemed/re-spent within seconds or allowed to settle on-chain beforehand. The costs should remain about this low for microtransactions. Syscoin will achieve further reduction of fees and even greater scalability with offchain payment channels for assets, with Z-DAG as a resilience fallback. New payment channel technology is one of the topics under research by the Syscoin development team with our academic partners at TU Delft. In line with the calculation in the Lightning Networks white paper, payment channels using assets with Syscoin Core will bring theoretical capacity for each person on Earth (7.8 billion) to have five on-chain transactions per year, per person, without requiring anyone to enter a fee market (aka “wait for a block”). This exceeds the minimum LN expectation of two transactions per person, per year; one to exist on-chain and one to settle aggregated value. # Tools, Infrastructure & Documentation ## Syscoin Bridge Mainnet Demonstration of Syscoin Bridge with the Basic Attention Token ERC-20 A two-way blockchain interoperability system that uses Simple Payment Verification to enable: • Any Standard ERC-20 token to be moved from Ethereum to the Syscoin blockchain as a Syscoin Platform Token (SPT), and back to Ethereum • Any SPT to be moved from Syscoin to the Ethereum blockchain as an ERC-20 token, and back to Syscoin ## Benefits • Permissionless • No counterparties involved • No trading mechanisms involved • No third-party liquidity providers required • Cross-chain Fractional Supply - 2-way peg - Token supply maintained globally • ERC-20s gain vastly improved transactionality with the Syscoin Token Platform, along with the security of bitcoin-core-compliant PoW. • SPTs gain access to all the tooling, applications and capabilities of Ethereum for ERC-20, including smart contracts. https://preview.redd.it/l8t2m8ldh8e51.png?width=1180&format=png&auto=webp&s=b0a955a0181746dc79aff718bd0bf607d3c3aa23 https://preview.redd.it/26htnxzfh8e51.png?width=1180&format=png&auto=webp&s=d0383d3c2ee836c9f60b57eca35542e9545f741d ## Source code https://github.com/syscoin/?q=sysethereum Main Subprojects ## API Tools to simplify using Syscoin Bridge as a service with dapps and wallets will be released some time after implementation of Syscoin Core 4.2. These will be based upon the same processes which are automated in the current live Sysethereum Dapp that is functioning with the Syscoin mainnet. ## Documentation Syscoin Bridge & How it Works (description and process flow) Superblock Validation Battles HOWTO: Provision the Bridge for your ERC-20 HOWTO: Setup an Agent Developer & User Diligence ## Trade-off The Syscoin Ethereum Bridge is secured by Agent nodes participating in a decentralized and incentivized model that involves roles of Superblock challengers and submitters. This model is open to participation. The benefits here are trust-minimization, permissionless-ness, and potentially less legal/regulatory red-tape than interop mechanisms that involve liquidity providers and/or trading mechanisms. The trade-off is that due to the decentralized nature there are cross-chain settlement times of one hour to cross from Ethereum to Syscoin, and three hours to cross from Syscoin to Ethereum. We are exploring ways to reduce this time while maintaining decentralization via zkp. Even so, an “instant bridge” experience could be provided by means of a third-party liquidity mechanism. That option exists but is not required for bridge functionality today. Typically bridges are used with batch value, not with high frequencies of smaller values, and generally it is advantageous to keep some value on both chains for maximum availability of utility. Even so, the cross-chain settlement time is good to mention here. ## Cost Ethereum -> Syscoin: Matic or Ethereum transaction fee for bridge contract interaction, negligible Syscoin transaction fee for minting tokens Syscoin -> Ethereum: Negligible Syscoin transaction fee for burning tokens, 0.01% transaction fee paid to Bridge Agent in the form of the ERC-20, Matic or Ethereum transaction fee for contract interaction. ## Z-DAG Zero-Confirmation Directed Acyclic Graph is an instant settlement protocol that is used as a complementary system to proof-of-work (PoW) in the confirmation of Syscoin service transactions. In essence, a Z-DAG is simply a directed acyclic graph (DAG) where validating nodes verify the sequential ordering of transactions that are received in their memory pools. Z-DAG is used by the validating nodes across the network to ensure that there is absolute consensus on the ordering of transactions and no balances are overflowed (no double-spends). ## Benefits • Unique fee-market that is more efficient for microtransaction redemption and settlement • Uses decentralized means to enable tokens with value transfer scalability that is comparable or exceeds that of credit card networks • Provides high throughput and secure fulfillment even if blocks are full • Probabilistic and interactive • 99.9999% security assurance within 10 seconds • Can serve payment channels as a resilience fallback that is faster and lower-cost than falling-back directly to a blockchain • Each Z-DAG transaction also settles onchain through Syscoin Core at 60-second block target using SHA-256 Proof of Work consensus https://preview.redd.it/pgbx84jih8e51.png?width=1614&format=png&auto=webp&s=5f631d42a33dc698365eb8dd184b6d442def6640 ## Source code https://github.com/syscoin/syscoin ## API Syscoin-js provides tooling for all Syscoin Core RPCs including interactivity with Z-DAG. ## Documentation Z-DAG White Paper Useful read: An in-depth Z-DAG discussion between Syscoin Core developer Jag Sidhu and Brave Software Research Engineer Gonçalo Pestana ## Trade-off Z-DAG enables the ideal speed/security tradeoff to be determined per use-case in the application layer. It minimizes the sacrifice required to accept and redeem fast transfers/payments while providing more-than-ample security for microtransactions. This is supported on the premise that a Reddit user receiving points does need security yet generally doesn’t want nor need to wait for the same level of security as a nation-state settling an international trade debt. In any case, each Z-DAG transaction settles onchain at a block target of 60 seconds. # Syscoin Specs Syscoin 3.0 White Paper (4.0 white paper is pending. For improved scalability and less blockchain bloat, some features of v3 no longer exist in current v4: Specifically Marketplace Offers, Aliases, Escrow, Certificates, Pruning, Encrypted Messaging) • 16MB block bandwidth per minute assuming segwit witness carrying transactions, and transactions ~200 bytes on average • SHA256 merge mined with Bitcoin • UTXO asset layer, with base Syscoin layer sharing identical security policies as Bitcoin Core • Z-DAG on asset layer, bridge to Ethereum on asset layer • On-chain scaling with prospect of enabling enterprise grade reliable trustless payment processing with on/offchain hybrid solution • Focus only on Simple Value Transfers. MVP of blockchain consensus footprint is balances and ownership of them. Everything else can reduce data availability in exchange for scale (Ethereum 2.0 model). We leave that to other designs, we focus on transfers. • Future integrations of MAST/Taproot to get more complex value transfers without trading off trustlessness or decentralization. • Zero-knowledge Proofs are a cryptographic new frontier. We are dabbling here to generalize the concept of bridging and also verify the state of a chain efficiently. We also apply it in our Digital Identity projects at Blockchain Foundry (a publicly traded company which develops Syscoin softwares for clients). We are also looking to integrate privacy preserving payment channels for off-chain payments through zkSNARK hub & spoke design which does not suffer from the HTLC attack vectors evident on LN. Much of the issues plaguing Lightning Network can be resolved using a zkSNARK design whilst also providing the ability to do a multi-asset payment channel system. Currently we found a showstopper attack (American Call Option) on LN if we were to use multiple-assets. This would not exist in a system such as this. ## Wallets Web3 and mobile wallets are under active development by Blockchain Foundry Inc as WebAssembly applications and expected for release not long after mainnet deployment of Syscoin Core 4.2. Both of these will be multi-coin wallets that support Syscoin, SPTs, Ethereum, and ERC-20 tokens. The Web3 wallet will provide functionality similar to Metamask. Syscoin Platform and tokens are already integrated with Blockbook. Custom hardware wallet support currently exists via ElectrumSys. First-class HW wallet integration through apps such as Ledger Live will exist after 4.2. Current supported wallets Syscoin Spark Desktop Syscoin-Qt ## Explorers Mainnet: https://sys1.bcfn.ca (Blockbook) Testnet: https://explorer-testnet.blockchainfoundry.co # Thank you for close consideration of our proposal. We look forward to feedback, and to working with the Reddit community to implement an ideal solution using Syscoin Platform! submitted by sidhujag to ethereum [link] [comments] ##### The Truth about Bitcoin? Part 1/4 - NSA Connection: First off, the SHA-256 algorithm, which stands for Secure Hash Algorithm 256, is a member of the SHA-2 cryptographic hash functions designed by the NSA and first published in 2001. SHA-256, like other hash functions, takes any input and produces an output (often called a hash) of fixed length. The output of a hashing algorithm such as SHA-256 will always be the same length - regardless of the input size. Specifically, the output is, as the name suggests, 256 bits. Moreover, all outputs appear completely random and offer no information about the input that created it. The Bitcoin Network utilises the SHA-256 algorithm for mining and the creation of new addresses. Who is Satoshi Nakamoto? What does Satoshi Nakamoto mean? Out of respect for their anonymity, it would be rude to speculate in a video about who Satoshi Nakamoto is likely to be. The reality is, it's not important. Let me explain: Any human being can be attacked. Jesus could come back from the dead, and there would be haters. Therefore, the Satoshi Nakamoto approach neutralises the natural human herd behaviour, exacerbated by the media, to attack and discredit. This is a very important part of Bitcoin's success thus far. Also, from a security perspective, those who wish to dox Satoshi Nakamoto in a video are essentially putting his, or her, or their, life at risk...for the sake of views. As a genius who has produced an innovation not just from a technical perspective but also a monetary perspective, they should be treated with more respect than that. As for the name Satoshi Nakamoto, I would speculate that it is a homage to Tatsuaki Okamoto and Satoshi Obana - two cryptographers from Japan. There is another reason for the name, but that...is confidential. In 1996, the NSA's Cryptology Division of their Office of Information Security Research and Technology published a paper titled: "How to make a mint: The cryptography of anonymous electronic cash", first publishing it in an MIT mailing list and later, in 1997, in the American University Law Review. One of the researchers they referenced was Tatsuaki Okamoto. Part 2/4 - 'Crypto Market': Most of the crypto market is a scam. By the way, this was predicted very early on in the Bitcoin Talk forums - check out this interaction from November 8th, 2010: "if bitcoin really takes off I can see lots of get-rich-quick imitators coming on the scene: gitcoin, nitcoin, witcoin, titcoin, shitcoin... Of course the cheap imitators will disappear as quickly as those 1990s "internet currencies", but lots of people will get burned along the way." To which Bitcoin OG Gavin Andresen replies: "I agree - we're in the Wild West days of open-source currency. I expect people will get burned by scams, imitators, ponzi schemes and price bubbles." "I don't think there's a whole lot that can be done about scammers, imitators and ponzi schemes besides warning people to be careful with their money (whether dollars, euros or bitcoins)." Now, on the one hand, lack of regulation is more meritocratic (as you don't have to be an accredited investor just to get access). On the other hand, it means that crypto is, as Gavin said, a Wild West environment, with many cowboys in the Desert. Be careful. This is the same with most online courses - particularly 'How to get rich quick' courses - however with crypto you have an exponential increase in the supply of victims during the bull cycles so it is particularly prevalent during those times. In addition to this, leverage trading exchanges, which are no different to casinos, prey on naive retail traders who: A) Think they can outsmart professional traders with actual risk management skills; and B) Think they can outsmart the exchanges themselves who have an informational advantage as well as an incentive to chase stop losses and liquidate positions. Part 3/4 - CBDCs: The Fed and Central Banks around the world have printed themselves into a corner. Quantitative easing was the band-aid for the Great Financial Crisis in 2008, and more recent events have propelled the rate of money printing to absurd levels. This means that all currencies are in a race to zero - and it becomes a game of who can print more fiat faster. The powers that be know that this fiat frenzy is unsustainable, and that more and more people are becoming aware that it is a debt based system, based on nothing. The monetary system devised by bankers, for bankers, in 1913 on Jekyll Island and supercharged in 1971 is fairly archaic and also does not allow for meritocratic value transfer - fiat printing itself increases inequality. They, obviously, know this (as it is by design). The issue (for them) is that more and more people are starting to become aware of this. Moving to a modernised monetary system will allow those who have rigged the rules of the game for the last Century to get away scot-free. It will also pave the way for a new wealthy, and more tech literate, elite to emerge - again predicted in the Bitcoin Talk forums. Now...back to the powers that be. Bitcoin provides a natural transition to Central Bank Digital Currencies (CBDCs) and what I would describe as Finance 2.0, but what are the benefits of CBDCs for the state? More control, easier tax collection, more flexibility in monetary policy (i.e. negative interest rates) and generally a more efficient monetary system. This leads us to the kicker: which is the war on cash. The cashless society was a fantasy just a few years ago, however now it doesn't seem so far fetched. No comment. Part 4/4 - Bitcoin: What about Bitcoin? Well, Bitcoin has incredibly strong network effects; it is the most powerful computer network in the World. But what about Bitcoin's reputation? Bankers hate it. Warren Buffett hates it. Precisely, and the public hates bankers. Sure, the investing public respects Buffett, but the general public perception of anyone worth$73 billion is not exactly at all time highs right now amid record wealth inequality.
In the grand scheme of things, the market cap of Bitcoin is currently around $179 billion. For example, the market cap of Gold is around$9 trillion, which is 50x the Market Cap of Bitcoin.
Money has certain characteristics.
In my opinion, what makes Bitcoin unique is the fact that it has a finite total supply (21 million) and a predictable supply schedule via the halving events every 4 years, which cut in half the rate at which new Bitcoin is released into circulation.
Clearly, with these properties, it seems likely that Bitcoin could act as a meaningful hedge against inflation.
One of the key strengths of Bitcoin is the fact that the Network is decentralised...
Many people don't know that PayPal originally wanted to create a global currency similar to crypto.
Overall, a speculative thesis would be the following:
Satoshi Nakamoto is one of the most important entities of the 21st Century, and will accelerate the next transition of the human race.
Trusted third parties are security holes.
Bitcoin is the catalyst for Finance 2.0, whereby value transfer is conducted in a more meritocratic and decentralised fashion.
In 1964, Russian astrophysicist Nikolai Kardashev designed the Kardashev Scale.
At the time, he was looking for signs of extraterrestrial life within cosmic signals.
The Scale has three categories, which are based on the amount of usable energy a civilisation has at its disposal, and the degree of space colonisation.
Generally, a Type 1 Civilisation has achieved mastery of its home planet (10^16W);
A Type 2 Civilisation has mastery over its solar system (10^26W);
and a Type 3 Civilisation has mastery over its Galaxy (10^36W).
We humans are a Type 0 Civilisation on this Scale.
Nonetheless, our exponential technological growth in the few decades indicates that we are somewhere between Type 0 and Type 1.
In fact, according to Carl Sagan's interpolated Kardashev Scale and recent global energy consumption, we are about 0.73.
Physicist Freeman Dyson estimated that within 200 years or so, we should attain Type 1 status.
As a technology that, through its decentralisation, links entities globally and makes value transfer between humans more efficient, Bitcoin could prove a key piece of our progression as a civilisation.
Is it true...or false?

##### What is your personal financial strategy and vision of Gridcoin?

I started the 2020 year by totally ignoring what is a blockchain, or a cryptocoin. And once I started Qwant-ing (alt Google) it, it was a matter of a few days that I learned how to CPU and GPU mine. I even got a SHA-256 ASIC warming up my flat. Of course, the more I learned about Bitcoin and other PoW coins, the worse I was feeling about the incredible waste of energy with such useless hashes and the consequences of the greedy speculation against the "smaller" coins. So I got rid of the ASIC and while looking at the web for alternative coins using PoS or similar, I found this project, in which I really get identified. Now I'm a happy math and astronomy cruncher. It's just amazing, to be crunching and at the same time, getting rewarded.
There are plenty of things to contribute to this project, and I feel really motivated to get further involved into it. Now my question concerns the "money" side, the financial stuff. Of course Gridcoin is not Bitcoin, although it seems that Gridcoin has a long story behind. I see potential, mostly due to the very active community, the increasing interest in Distributed Computing (and thus the eventual popularity of the Proof-of-Research concept) and the "seriousness" of this project. But the perpetual inflation and the apparent lack of significant volume exchanges might underestimate its value, strictly speaking of the markets dynamics.
The growing scarcity and popularity of the mainstream coins might also be pushing this coin out of the radar of most of the people, explaining the actual stagnancy of the GRC market. And so, here is where I ask to you: what is your vision of Gridcoin? Do you (personally) bet everything for this project, in terms of investments (GRC-only wallets) and computational resources? Or do you diversify your portfolios, speculating as well in another cryptos/stocks?
I'd really like to hear from you, to know if you're interested (or not) in the money side of the project, and, for the affirmative case, to know why you're here and why you want to stay here. Thank you for your attention and your feedback!

His goal is to utterly strip bitcoins of all value, or at least come as close to it as he can, and to totally discredit it as any form of currency or medium of exchange. Superman is mostly in-character, and will not kill under any circumstances. However, he is willing to break the law as long as it doesn't significantly hurt anyone (outside of any damage done by the loss of Bitcoin's value, which he is obviously utterly indifferent to) and provided he isn't caught. Additionally, he doesn't want anyone to find out he is responsible for this. Assume that no other superhero or super-powered being will investigate or care, but if ordinary people find out he's responsible, he loses. How much damage can Superman do to the Bitcoin economy? R1. Superman can use whatever tactics he pleases, within the above constraints. R2. Superman's hatred of Bitcoins means that he will not participate in the economy himself by any means - he won't purchase, mine for, or legitimately interact with the Bitcoin market in any way, shape, or form. However, in this round, he is willing to cause damage by breaking the law, as long as he doesn't kill anyone. R3. Superman is bloodlusted and willing to kill anyone who owns or has ever owned a Bitcoin in order to stop Bitcoins. He has 24 hours. He still loses if it's generally discovered that he's responsible, and he won't kill anyone who has never interacted with Bitcoins (so no just throwing the earth into the sun.) R4. As R1, but Batman has converted the entire Wayne family fortune into Bitcoins and is now determined to protect them. Both Batman and Superman are in-character otherwise, won't harm each other if they can help it (outside of Superman hurting Batman financially by crashing the value of his Bitcoins, of course), and won't kill each other under any circumstances. Batman will not out Superman as the source of the problem regardless of the situation. No Kryptonite or other things that nullify Superman's powers. submitted by Yglorba to whowouldwin [link] [comments] ##### The Truth about Bitcoin?

Bitcoin provides a natural transition to Central Bank Digital Currencies (CBDCs) and what I would describe as Finance 2.0, but what are the benefits of CBDCs for the state? More control, easier tax collection, more flexibility in monetary policy (i.e. negative interest rates) and generally a more efficient monetary system. This leads us to the kicker: which is the war on cash. The cashless society was a fantasy just a few years ago, however now it doesn't seem so far fetched. No comment. Part 4/4 - Bitcoin: What about Bitcoin? Well, Bitcoin has incredibly strong network effects; it is the most powerful computer network in the World. But what about Bitcoin's reputation? Bankers hate it. Warren Buffett hates it. Precisely, and the public hates bankers. Sure, the investing public respects Buffett, but the general public perception of anyone worth$73 billion is not exactly at all time highs right now amid record wealth inequality.
In the grand scheme of things, the market cap of Bitcoin is currently around $179 billion. For example, the market cap of Gold is around$9 trillion, which is 50x the Market Cap of Bitcoin.
Money has certain characteristics.
In my opinion, what makes Bitcoin unique is the fact that it has a finite total supply (21 million) and a predictable supply schedule via the halving events every 4 years, which cut in half the rate at which new Bitcoin is released into circulation.
Clearly, with these properties, it seems likely that Bitcoin could act as a meaningful hedge against inflation.
One of the key strengths of Bitcoin is the fact that the Network is decentralised...
Many people don't know that PayPal originally wanted to create a global currency similar to crypto.
Overall, a speculative thesis would be the following:
Satoshi Nakamoto is one of the most important entities of the 21st Century, and will accelerate the next transition of the human race.
Trusted third parties are security holes.
Bitcoin is the catalyst for Finance 2.0, whereby value transfer is conducted in a more meritocratic and decentralised fashion.
In 1964, Russian astrophysicist Nikolai Kardashev designed the Kardashev Scale.
At the time, he was looking for signs of extraterrestrial life within cosmic signals.
The Scale has three categories, which are based on the amount of usable energy a civilisation has at its disposal, and the degree of space colonisation.
Generally, a Type 1 Civilisation has achieved mastery of its home planet (10^16W);
A Type 2 Civilisation has mastery over its solar system (10^26W);
and a Type 3 Civilisation has mastery over its Galaxy (10^36W).
We humans are a Type 0 Civilisation on this Scale.
Nonetheless, our exponential technological growth in the few decades indicates that we are somewhere between Type 0 and Type 1.
In fact, according to Carl Sagan's interpolated Kardashev Scale and recent global energy consumption, we are about 0.73.
Physicist Freeman Dyson estimated that within 200 years or so, we should attain Type 1 status.
As a technology that, through its decentralisation, links entities globally and makes value transfer between humans more efficient, Bitcoin could prove a key piece of our progression as a civilisation.
Is it true...or false?

Part 1/4 - NSA Connection:
First off, the SHA-256 algorithm, which stands for Secure Hash Algorithm 256, is a member of the SHA-2 cryptographic hash functions designed by the NSA and first published in 2001.
SHA-256, like other hash functions, takes any input and produces an output (often called a hash) of fixed length. The output of a hashing algorithm such as SHA-256 will always be the same length - regardless of the input size. Specifically, the output is, as the name suggests, 256 bits.
Moreover, all outputs appear completely random and offer no information about the input that created it.
The Bitcoin Network utilises the SHA-256 algorithm for mining and the creation of new addresses.
Who is Satoshi Nakamoto? What does Satoshi Nakamoto mean?
Out of respect for their anonymity, it would be rude to speculate in a video about who Satoshi Nakamoto is likely to be. The reality is, it's not important. Let me explain: Any human being can be attacked. Jesus could come back from the dead, and there would be haters. Therefore, the Satoshi Nakamoto approach neutralises the natural human herd behaviour, exacerbated by the media, to attack and discredit. This is a very important part of Bitcoin's success thus far. Also, from a security perspective, those who wish to dox Satoshi Nakamoto in a video are essentially putting his, or her, or their, life at risk...for the sake of views.
As a genius who has produced an innovation not just from a technical perspective but also a monetary perspective, they should be treated with more respect than that.
As for the name Satoshi Nakamoto, I would speculate that it is a homage to Tatsuaki Okamoto and Satoshi Obana - two cryptographers from Japan. There is another reason for the name, but that...is confidential.
In 1996, the NSA's Cryptology Division of their Office of Information Security Research and Technology published a paper titled: "How to make a mint: The cryptography of anonymous electronic cash", first publishing it in an MIT mailing list and later, in 1997, in the American University Law Review. One of the researchers they referenced was Tatsuaki Okamoto.

Part 2/4 - 'Crypto Market':
Most of the crypto market is a scam.
By the way, this was predicted very early on in the Bitcoin Talk forums - check out this interaction from November 8th, 2010:
"if bitcoin really takes off I can see lots of get-rich-quick imitators coming on the scene: gitcoin, nitcoin, witcoin, titcoin, shitcoin...
Of course the cheap imitators will disappear as quickly as those 1990s "internet currencies", but lots of people will get burned along the way."
To which Bitcoin OG Gavin Andresen replies:
"I agree - we're in the Wild West days of open-source currency. I expect people will get burned by scams, imitators, ponzi schemes and price bubbles."
"I don't think there's a whole lot that can be done about scammers, imitators and ponzi schemes besides warning people to be careful with their money (whether dollars, euros or bitcoins)."
Now, on the one hand, lack of regulation is more meritocratic (as you don't have to be an accredited investor just to get access).
On the other hand, it means that crypto is, as Gavin said, a Wild West environment, with many cowboys in the Desert. Be careful.
This is the same with most online courses - particularly 'How to get rich quick' courses - however with crypto you have an exponential increase in the supply of victims during the bull cycles so it is particularly prevalent during those times.
In addition to this, leverage trading exchanges, which are no different to casinos, prey on naive retail traders who:
A) Think they can outsmart professional traders with actual risk management skills; and
B) Think they can outsmart the exchanges themselves who have an informational advantage as well as an incentive to chase stop losses and liquidate positions.

Part 3/4 - CBDCs:
The Fed and Central Banks around the world have printed themselves into a corner.
Quantitative easing was the band-aid for the Great Financial Crisis in 2008, and more recent events have propelled the rate of money printing to absurd levels.
This means that all currencies are in a race to zero - and it becomes a game of who can print more fiat faster.
The powers that be know that this fiat frenzy is unsustainable, and that more and more people are becoming aware that it is a debt based system, based on nothing.
The monetary system devised by bankers, for bankers, in 1913 on Jekyll Island and supercharged in 1971 is fairly archaic and also does not allow for meritocratic value transfer - fiat printing itself increases inequality.
They, obviously, know this (as it is by design).
The issue (for them) is that more and more people are starting to become aware of this.
Moving to a modernised monetary system will allow those who have rigged the rules of the game for the last Century to get away scot-free.
It will also pave the way for a new wealthy, and more tech literate, elite to emerge - again predicted in the Bitcoin Talk forums.
Now...back to the powers that be.

What are your thoughts? Is it true...or false? https://www.youtube.com/watch?v=1oQLOqpP1ZM submitted by financeoptimum to economy [link] [comments] ##### What is Blockchain Technology? The original article appeared here: https://www.securities.io/what-is-blockchain-technology/ Its been almost ten years since Satoshi Nakamoto first introduced Blockchain technology to the world in his 2008 Bitcoin Whitepaper. Since that time, these revolutionary networks have gained popularity in both the corporate and governmental sectors. This growth is easily explained when you consider that blockchain technology provides the world with some unique advantages that were previously unimaginable. Consequently, today, you can find blockchain technology in nearly every sector of the global economy. ## What is Blockchain Technology? A blockchain is a network of computers that share a distributed ledger across all network participants (nodes). This strategy is far different than say, fiat currencies that originate from a centralized authority figure. Importantly, this ledger keeps an unbroken chain of transactions since the birth of the network. This “chain” of transactions grows larger as new “blocks” of transactions are approved and added to it. Bitcoin Whitepaper In order to approve new transactions, each node works together with others to validate new blocks. Additionally, the nodes also validate the current state of the entire blockchain. In order for a new block of transactions to be added to the blockchain, they must receive approval from 51% of the network’s nodes. Nodes are also referred to as miners. In this manner, blockchain networks are decentralized networks that provide unmatched security to the world of digital assets. ## Security via Decentralization Decentralization is an important aspect of blockchain technology because it makes these revolutionary ledgers immutable and unalterable. In fact, since there is no centralized attack vector, hacking a blockchain is nearly impossible. The larger the blockchain network, the more secure the data on it remains. For example, let’s look at the world’s largest blockchain, Bitcoin. Currently, the Bitcoin blockchain has over 10,000 active nodes located across the globe. This distribution means that in order for an attacker to alter even just one tiny piece of information on the blockchain, they would need to successfully hack 5,000+ computers at once. While this task may not be impossible for the quantum computers of the future, it’s so unprofitable that it makes no sense to even attempt such a monumental task. Additionally, on top of successfully hacking 5000+ computers at once, an attacker would also need a supercomputer to recalculate the new blockchain transactions in time to introduce them into the network. It would literally be more affordable to create a new cryptocurrency from scratch. ## Consensus Mechanisms One of the reasons why blockchain networks are so secure is the integration of consensus mechanisms. Consensus mechanisms are cryptographic protocols that leverage the participants of a blockchain network in securing its data. In the case of Bitcoin, the Proof-of-Work (PoW) consensus mechanism is used. ## Proof-of-Work (PoW) The Proof-of-Work consensus mechanism was revolutionary to the world of cryptography when it was first introduced years prior by Adam Back in his Hashcash whitepaper. In the concept, Back describes the integration of a mathematical equation to the network’s security protocols. In this way, every computer can show “proof” of their work securing the network. ## Miner Rewards It’s important to understand that nodes receive a reward for their mining efforts. These rewards adjust automatically depending on the network’s difficulty and value. In the case of Bitcoin, miners originally received 50 Bitcoin for their efforts. Today, this seems like fortune, but back in 2009, Bitcoin was only worth pennies. As the value of the token rises and the network goes, the mining rewards shrink. Today, Bitcoin miners receive 6.5 BTC if they add the next block to the chain. ## SHA-256 Notably, every node validates and secures the blockchain, but only one gets to add the next block of transactions to the network. To determine who the next miner is that gets to add this block, every computer competes in a mathematical race to figure out the PoW equation. In the case of Bitcoin, the equation is known as SHA-256. Importantly, the first SHA algorithm dates back to Hashcash. This early version of the equation was known as SHA-1. Notably, the SHA-256 equation is so difficult that it’s easier and more efficient for your computer to just make random guesses rather than attempting to figure out the equation directly. The answer to the equation must begin with a predetermined amount of 0s. In the Bitcoin blockchain, the equation’s answer must start with four zeros. However, if the network’s congestion rises, so does the difficulty of these equations. This difficulty adjusts by the addition of another zero at the beginning of the required SHA-256 answer. Similarly to traditional commodities such as gold, there are costs that are associated with the creation and introduction of these digital assets into the market. These random guesses utilize intense computational power. This power equates to real-world costs such as electricity bills. Studies have shown that securing the Bitcoin network can use more electricity than required by entire countries. Luckily, over 80% of Bitcoin’s power consumption comes from renewable sources such as solar or hydroelectric. This cost of mining also adds measurable value to each Bitcoin. ## Miners As Bitcoin began to gain in profitability, its network’s computing power expanded significantly. In the beginning, nodes, also known as miners, could mine for Bitcoin using nothing more than your home PC. Eventually, miners realized that graphic cards were far better at the repetitive guessing required to figure out the SHA-256 algorithm. This led to a computational race in the market. ## ASIC Eventually, large blockchain firms such as Bitmain introduced Application Specific Integrated Circuit (ASIC) miners into the equation. These purpose-built miners were thousands of times more efficient at guessing the SHA-256 algorithm than the GPUs and CPUs before them. Consequently, their introduction created a scenario in which the average miner now needed to invest thousands in mining equipment to stay relevant. ## Mining Pools Luckily, some creative minds in the field began to think of ways to level the playing field out again. They developed “mining pools.” A mining pool is a network of miners that all share computational power for the common goal of mining blockchain transactions. Importantly, mining pool participants receive a percentage of the reward based on their contributions to the network’s overall hash (computational power). Importantly, over the last three years, there has been a push to move away from power-hungry consensus mechanisms such as PoW. This desire to secure blockchains in a more efficient manner has led to the development of some truly unique consensus mechanisms in the sector. ## Proof-of-Stake (PoS) The Proof-of-Stake mechanism does away with the difficult mathematical algorithms and instead utilizes a more psychological approach to securing the network. In a PoS blockchain, users don’t need to compete mathematically to add the next block to the blockchain. Instead, PoS users “stake” their coins via network wallets to secure the network. The way staking works is simple. Keeping a certain amount of coins in your wallet allows you to participate in transaction validations. The more coins you stake, the more likely the chances are you get to add the next block of transactions to the network. In most PoS systems, a miner from those with the most tokens staked at the time receives the chance to add the blocks. The advantages of a PoS consensus mechanism are immediately evident. For one, you don’t need to pour tons of resources into your network to keep it safe. Additionally, since nodes are chosen based on their amount of staked coins, there is never a scenario in which a node gains anything from validating incorrect transactions. Basically, a hacker would have to fully invest in the cryptocurrency prior to attacking the network. In this way, PoS systems create a huge deterrent to attackers. ## The Future of Blockchain Technology Blockchain technology has come a long way from its early days as a means to secure cryptocurrency networks. Today, blockchain technology has numerous uses across every type of industry imaginable. Specifically, blockchain programs have impacted the logistical, financial, and data security sectors in a major way. ## Blockchain Technology Logistics Blockchain logistical systems are more efficient and cost-effective to operate than traditional paper-based models. In fact, the immutable and unalterable nature of blockchain tech makes it ideally suited to logistical tasks. Soon, you may be able to ascertain much more information regarding the creation and delivery of your products thanks to these new-age systems emerging. ## Fundraising Blockchain technology has also altered the way in which businesses raise funds. In a traditional corporate crowdfunding strategy such as an IPO, companies must balance between cost-effectiveness and participation. The inability to process smaller transactions meant that for the longest time, companies had to turn away potential investors. Nowadays, blockchain technology enables businesses to easily automate these procedures via smart contracts. ## Smart Contracts Smart Contracts feature preprogrammed protocols that execute when they receive a certain amount of cryptocurrency sent to their address. These contracts live on the blockchain and enable remarkable functionality. For example, in the case of fundraising, a smart contract can automate processes such as the approval of investors and the distribution of funds. ## Blockchain Technology Today You can expect to see further expansion of the blockchain sector in the coming months as more governments and institutions explore its benefits. For now, the blockchain revolution is well underway. submitted by BlockDotCo to u/BlockDotCo [link] [comments] ##### 30+ Reasons Why Cryptocurrencies Are Worthless 1)It is possible to change the code through a miner vote or a fork and change the total supply or anything. DASH did it : they reduced the total supply from 84M to 18.9M a few years ago. They could also increase it to 999 Trillions if they wanted to so that millions of DASH are mined every week. 2)You can also fork bitcoin anytime , start over from 0 and claim it's the real bitcoin. (BCH , BSV , BTG , LTC , BCD etc) 3)Why would you pay$10,000 for a digital collectible unit called BTC when you can use BCH or TRX or LTC .. you name it. They work just as fine and cost less. There is no rarity like in gold.

4)Think of any amount you hold in ethereum as a gift card to use smart contracts on the ETH blockchain. Ridiculous. You’d rather hold a wal mart gift card or even simply cash.

5)Private keys may be bruteforced as we speak. Quintillions entries a second. When they’ll have enough bitcoins under control , they could move them all at once instantly.(At least 45,000 ETH have been stolen this way for now through ethereum bandit)SHA 256 is too old , bitcoin is 10 years old , it is not secure enough , quantum computing could potentially break it.

6)And that’s if people don’t find a way to create an infinite amount of coins to sell on exchanges.. it happened with monero , stellar , bitcoin , zcash , zcoin , eos , etc..

proofs :

“Bitcoin , Coindesk : “The Latest Bitcoin Bug Was So Bad, Developers Kept Its Full Details a Secret”an attacker could have actually used it to create new Bitcoin — above the 21 million hard-cap of coin creation — thereby inflating the supply and devaluing current bitcoins.”

Stellar : “Stellar Inflation: Glitch Leads to 2.25 Billion Extra XLM Printed”

Monero : “A bug in the Monero (XMR) wallet software that could enable fake deposits to exchanges has been recently brought to public attention through a Medium post”

Zcoin : Forged coins were created, but not exceeding 1% of the circulating supply. We will release further details on exact numbers when Sigma is released.

EOS : “Hackers Forge Billion EOS Coins to Steal Real Crypto From DEX “

Zcash : “Zcash Team Reveals It Fixed a Catastrophic Coin Counterfeiting Bug” etc..

7)Segwit , and especially Lightning network is a very complex technology and it will inevitably have flaws , bugs , it will be exploited and people will lose money. That alone can cause bitcoin to drop very low levels.

8)Then miners may be losing millions so they will stop mining , blocks may be so slow , almost no transaction will come though , and bitcoin may not have enough time to reach the next difficulty adjustement. This is reffered to as a death spiral. Then every crypto even those with no mining involved may crash hard.

9)Many crypto wallets are unsafe and have already caused people to lose all their investment , including the infamous “parity wallet”.

10)It is NOT trustless. you have to trust the wallet you’re using is not just generating an address controlled by the developper , you have to trust the node the wallet connects to is an honest node , you have to trust a Rogue state or organization with enough computing power will not 51% attack the network. etc..

11)Bitcoin is NOT deflationary. Bitcoins are created every blocks (roughly every 10 minutes) and you wil be dead by the time we reach the 21 million current hard cap.

12)Bitcoin price may artificially be inflated by Tether.

13)It’s an energy waste , an environmental catastrophy.

14)The only usecases are money laundering , tax evasion , gambling , buying on the dark net , evading sanctions and speculation.

15)Governments will ban it if it gets too big , and they have a big incentive to do so , not only for the obscure usecases but also because it threatens the stability of sovereign currencies. Trump could kill bitcoin with one tweet , force fiat exchanges to cease activity.

16)Most cryptos are scams , the rest are just crazy speculative casino investments.

17)It is pyramidal : early adopters intend to profit massively while last comers get crushed. That's not how money works. The overwhelming majority of crypto holders are buying it because they think they will be able to sell it to a higher price later. Money is supposed to be rather stable. That's why the best cryptocurrencies are USDT USDC etc..

18)The very few stores accepting bitcoin always have the real price in the local currency , not in bitcoin. And prices like 0.00456329 BTC are ridiculous !

19)About famous brokers listing bitcoin : they have to meet the demand in order to make money , it doesn't mean they approve it , some even short it (see interactive broker's CEO opinion on bitcoin)

20)People say cash is backed by nothing and losing value slowly , and yes it is very flawed , but there is a whole nation behind it , it's accepted everywhere , you can buy more things with it.

21)Everybody in crypto thinks that there will be a new bullrun and that then , they will sell. But because everybody thinks it will happen , it might not happen. The truth is past performance doesn’t indicate future performance and it is absolutely not guaranteed that there will ever be another bullrun. The markets are unpredictable.

22)Also BTC went from about $0.003 to the price it is today , so don’t think it’s cheap now. 23)There is no recourse if you’re scammed/hacked/made a mistake in the address etc. No chargebacks. But it might be possible to do a rollback (blockchain reorganization) to reverse some transactions. BSV did it. 24)In case of a financial crisis , the speculative assets would crash the most and bitcoin is far from being a non speculative safe heaven ; and governments might ban it to prevent fiat inflation to worsen. 25) Having to write down the private key somewhere or memorize it is a security flaw ! It’s insane to think a system like this will gain mass adoption. 26) The argument saying governments can not ban it because it is decentralized (like they banned drugs) doesn’t work for cryptos. First , drugs are much harder to find and much more expensive and unsafe because of the ban , and people are willing to take the risk because they like it. But if crypto is banned , value will drop too much , and if you can’t sell it for fiat without risking jail , goodluck to find a buyer. Fiat exchanges could close. Banks could terminate every crypto related bank account. And maybe then the mining death spiral would happen and kill all cryptos. 27) Crypto doesn’t exist. It’s like buying air. It’s just virtual collectibles generated by a code. Faguzzi, fugazzi, it’s a whazzie, it’s a whoozie.. it’s a.. fairy dust. It doesn’t exist. It’s never landed. It’s no matter, it’s not on the elemental chart. It… it’s not fucking real! 28) Most brilliant guys have come out and said Bitcoin was a scam or worthless. Including Bill Gates , Warren Buffet , The Wolf Of Wall Street… 29) Inflation is necessary for POW , BTC code will have to be changed to bypass the 21M cap or mining will die ! If BTC code is not changed to allow for miners to be paid reasonably , they will cease mining when the bitcoin block reward gets too low.Even monero understood it ,the code will have to be changed to allow for an infinite bitcoin supply (devaluating all current bitcoins) or the hash will decrease and the security of bitcoin will decrease dramatically and be 51% attacked 30) Don’t mix up blockchain and cryptos. Even blockchain is overrated. But when you hear this or that company is going blockchain , it doesn’t mean they support cryptocurrencies. 31) Craig Wright had a bitcoin mining company with Dave Kleinman (he died) and on january 1 2020 he claims he will be able to access the 1.1M BTC/BCH/BTG from the mining trust. He may or may not dump them on the market , he also said BTC had a fatal flaw and that by 2019 there will be no more BTC. 32) Hacks in cryptos are very common and usually massive. Billions of dollars in crypto have been stolen in the last 6 years. In may 2019 Binance was hacked and lost 7,000 BTC (and it’s far from being the biggest crypto hack). 33) Bitcoin was first. It's an ancient technology. Newer blockchains have privacy, smart contracts, distributed apps and more.Bitcoin is our future? Was the Model T the future of the automobile? (John Mc Afee) 34) IOTA investiguating stolen funds on mainnet. IOTA shuts down the whole network to deal with trinity wallet attack. 35) Compared to bitcoin other cryptos work just as fine and don't waste so much energy. 36 ) Everytime miners disagree on the updates it will create another version of bitcoin : problem of governance and legitimacy. 37) Cryptos are only legitimate if they act as a credit for a redeemable asset like USDT or gold backed coins. While the native language of the writter is not english , I think you get the point and it doesn't make it any less relevant. submitted by OverTheRedHills to u/OverTheRedHills [link] [comments] ##### Bitcoin and Meritocratic Capitalism Part 1/4 - NSA Connection: First off, the SHA-256 algorithm, which stands for Secure Hash Algorithm 256, is a member of the SHA-2 cryptographic hash functions designed by the NSA and first published in 2001.

They, obviously, know this (as it is by design). The issue (for them) is that more and more people are starting to become aware of this. Moving to a modernised monetary system will allow those who have rigged the rules of the game for the last Century to get away scot-free. It will also pave the way for a new wealthy, and more tech literate, elite to emerge - again predicted in the Bitcoin Talk forums. Now...back to the powers that be. Bitcoin provides a natural transition to Central Bank Digital Currencies (CBDCs) and what I would describe as Finance 2.0, but what are the benefits of CBDCs for the state? More control, easier tax collection, more flexibility in monetary policy (i.e. negative interest rates) and generally a more efficient monetary system. This leads us to the kicker: which is the war on cash. The cashless society was a fantasy just a few years ago, however now it doesn't seem so far fetched. No comment. Part 4/4 - Bitcoin: What about Bitcoin? Well, Bitcoin has incredibly strong network effects; it is the most powerful computer network in the World. But what about Bitcoin's reputation? Bankers hate it. Warren Buffett hates it. Precisely, and the public hates bankers. Sure, the investing public respects Buffett, but the general public perception of anyone worth$73 billion is not exactly at all time highs right now amid record wealth inequality.
In the grand scheme of things, the market cap of Bitcoin is currently around $179 billion. For example, the market cap of Gold is around$9 trillion, which is 50x the Market Cap of Bitcoin.
Money has certain characteristics.
In my opinion, what makes Bitcoin unique is the fact that it has a finite total supply (21 million) and a predictable supply schedule via the halving events every 4 years, which cut in half the rate at which new Bitcoin is released into circulation.
Clearly, with these properties, it seems likely that Bitcoin could act as a meaningful hedge against inflation.
One of the key strengths of Bitcoin is the fact that the Network is decentralised...
Many people don't know that PayPal originally wanted to create a global currency similar to crypto.
Overall, a speculative thesis would be the following:
Satoshi Nakamoto is one of the most important entities of the 21st Century, and will accelerate the next transition of the human race.
Trusted third parties are security holes.
Bitcoin is the catalyst for Finance 2.0, whereby value transfer is conducted in a more meritocratic and decentralised fashion.
In 1964, Russian astrophysicist Nikolai Kardashev designed the Kardashev Scale.
At the time, he was looking for signs of extraterrestrial life within cosmic signals.
The Scale has three categories, which are based on the amount of usable energy a civilisation has at its disposal, and the degree of space colonisation.
Generally, a Type 1 Civilisation has achieved mastery of its home planet (10^16W);
A Type 2 Civilisation has mastery over its solar system (10^26W);
and a Type 3 Civilisation has mastery over its Galaxy (10^36W).
We humans are a Type 0 Civilisation on this Scale.
Nonetheless, our exponential technological growth in the few decades indicates that we are somewhere between Type 0 and Type 1.
In fact, according to Carl Sagan's interpolated Kardashev Scale and recent global energy consumption, we are about 0.73.
Physicist Freeman Dyson estimated that within 200 years or so, we should attain Type 1 status.
As a technology that, through its decentralisation, links entities globally and makes value transfer between humans more efficient, Bitcoin could prove a key piece of our progression as a civilisation.
Is it true...or false?

Part 1/4 - NSA Connection:
First off, the SHA-256 algorithm, which stands for Secure Hash Algorithm 256, is a member of the SHA-2 cryptographic hash functions designed by the NSA and first published in 2001.
SHA-256, like other hash functions, takes any input and produces an output (often called a hash) of fixed length. The output of a hashing algorithm such as SHA-256 will always be the same length - regardless of the input size. Specifically, the output is, as the name suggests, 256 bits.
Moreover, all outputs appear completely random and offer no information about the input that created it.
The Bitcoin Network utilises the SHA-256 algorithm for mining and the creation of new addresses.
Who is Satoshi Nakamoto? What does Satoshi Nakamoto mean?
Out of respect for their anonymity, it would be rude to speculate in a video about who Satoshi Nakamoto is likely to be. The reality is, it's not important. Let me explain: Any human being can be attacked. Jesus could come back from the dead, and there would be haters. Therefore, the Satoshi Nakamoto approach neutralises the natural human herd behaviour, exacerbated by the media, to attack and discredit. This is a very important part of Bitcoin's success thus far. Also, from a security perspective, those who wish to dox Satoshi Nakamoto in a video are essentially putting his, or her, or their, life at risk...for the sake of views.
As a genius who has produced an innovation not just from a technical perspective but also a monetary perspective, they should be treated with more respect than that.
As for the name Satoshi Nakamoto, I would speculate that it is a homage to Tatsuaki Okamoto and Satoshi Obana - two cryptographers from Japan. There is another reason for the name, but that...is confidential.
In 1996, the NSA's Cryptology Division of their Office of Information Security Research and Technology published a paper titled: "How to make a mint: The cryptography of anonymous electronic cash", first publishing it in an MIT mailing list and later, in 1997, in the American University Law Review. One of the researchers they referenced was Tatsuaki Okamoto.

Part 2/4 - 'Crypto Market':
Most of the crypto market is a scam.
By the way, this was predicted very early on in the Bitcoin Talk forums - check out this interaction from November 8th, 2010:
"if bitcoin really takes off I can see lots of get-rich-quick imitators coming on the scene: gitcoin, nitcoin, witcoin, titcoin, shitcoin...
Of course the cheap imitators will disappear as quickly as those 1990s "internet currencies", but lots of people will get burned along the way."
To which Bitcoin OG Gavin Andresen replies:
"I agree - we're in the Wild West days of open-source currency. I expect people will get burned by scams, imitators, ponzi schemes and price bubbles."
"I don't think there's a whole lot that can be done about scammers, imitators and ponzi schemes besides warning people to be careful with their money (whether dollars, euros or bitcoins)."
Now, on the one hand, lack of regulation is more meritocratic (as you don't have to be an accredited investor just to get access).
On the other hand, it means that crypto is, as Gavin said, a Wild West environment, with many cowboys in the Desert. Be careful.
This is the same with most online courses - particularly 'How to get rich quick' courses - however with crypto you have an exponential increase in the supply of victims during the bull cycles so it is particularly prevalent during those times.
In addition to this, leverage trading exchanges, which are no different to casinos, prey on naive retail traders who:
A) Think they can outsmart professional traders with actual risk management skills; and
B) Think they can outsmart the exchanges themselves who have an informational advantage as well as an incentive to chase stop losses and liquidate positions.

Part 3/4 - CBDCs:
The Fed and Central Banks around the world have printed themselves into a corner.
Quantitative easing was the band-aid for the Great Financial Crisis in 2008, and more recent events have propelled the rate of money printing to absurd levels.
This means that all currencies are in a race to zero - and it becomes a game of who can print more fiat faster.
The powers that be know that this fiat frenzy is unsustainable, and that more and more people are becoming aware that it is a debt based system, based on nothing.
The monetary system devised by bankers, for bankers, in 1913 on Jekyll Island and supercharged in 1971 is fairly archaic and also does not allow for meritocratic value transfer - fiat printing itself increases inequality.
They, obviously, know this (as it is by design).
The issue (for them) is that more and more people are starting to become aware of this.
Moving to a modernised monetary system will allow those who have rigged the rules of the game for the last Century to get away scot-free.
It will also pave the way for a new wealthy, and more tech literate, elite to emerge - again predicted in the Bitcoin Talk forums.
Now...back to the powers that be.

# Mining solo versus pool

So let's face it - mining solo won't get you anywhere, so let's mine on a pool! If you have a really bad Hashrate, please consider that: Often you need about $1 or$2 worth of crypto to receive a payout (without fees). This means, you have to get there. With 100 MH/s on prohashing, it takes about 6 days, running 24/7 to get to that threshold. Now you can do the math... 1 MH/s = 1000 KH/s, if you are below 1 MH/s, you probably won't have fun.

You found an old BTC USB-miner with 24 GH/s (1 GH/s = 1000 MH/s) for $80 bucks - next stop lambo!? Sorry, bad news again, this hashrate is for SHA-256! If you want to mine LTC/Doge you will need a miner using scrypt with quite lower numbers on the hashrate per second, so don't fall for that. Often when you have a big miner (= also loud), you get more Hashrate per$ spent on the miner, but most will still run on a operational loss, because the electricity is too expensive and the miners will be outdated soon again. Leading me to my next point...

# Making profit

You won't make money running your miner. Just do the math: What if you would have bougth a miner 1 year ago? Substract costs for electricity and then compare to: What if you just have bought coins. In most cases you would have a greater profit by just buying coins, maybe even with a "stable" coin like Doges.

# Cloud Mining

Okay, this was a lot of text and you are still on the hook? Maybe you are desperated enough to invest in some cloud mining contract... But this isn't a good idea either, because most of such contracts are scams based on a ponzi scheme. You often can spot them easy, because they guarantee way to high profits, or they fake payouts that never happened, etc.
Just a thought: If someone in a subway says to you: Give me $1 and lets meet in one year, right here and I give you$54,211,841, you wouldn't trust him and if some mining contract says they will give you 5% a day it is basically the same.
Also rember the merged mining part. Nobody would offer you to mine Doges, they would offer you to buy a hashrate for scrypt that will apply on multiple chains.

# Alternative coins

Maybe try to mine a coin where you don't have ASICs yet, like Monero and exchange them to Doge. If somebody already tried this - feel free to add your thoughts!

# Folding at Home (Doge)

Some people say folding at home (FAH - https://www.dogecoinfah.com/) still the best. I just installed the tool and it says I would make 69.852 points a day, running on medium power what equates to 8 Doges. It is easy, it was fun, but it isn't much.

##### Help calculating DogeCoin mining expectations on 1 TH/s

Hello,
I was looking to buy 1 TH/s lifetime contract from genesis mining, dedicated for use in DogeCoin, but as this costs a lot of money (260 usd), I wanted to check if someone believes it is not worth it or something I should be worry of.
According to coinwarz calculators, it seems to be generating unbelieveable yields, but still, I am not sure if I make proper calculations ...
Does anyone know how much dogecoins would 1 TH/s of SHA-256 yield per day ?
Thanks for any help !!!

##### Looking back 18 months.

I was going through old emails today and came across this one I sent out to family on January 4, 2018. It was a reflection on the 2017 crypto bull market and where I saw it heading, as well as some general advice on crypto, investment, and being safe about how you handle yourself in cryptoland.
I feel that we are on the cusp of a new bull market right now, so I thought that I would put this out for at least a few people to see *before* the next bull run, not after. While the details have changed, I don't see a thing in this email that I fundamentally wouldn't say again, although I'd also probably insist that people get a Yubikey and use that for all 2FA where it is supported.
Happy reading, and sorry for some of the formatting weirdness -- I cleaned it up pretty well from the original email formatting, but I love lists and indents and Reddit has limitations... :-/
Also, don't laught at my token picks from January 2018! It was a long time ago and (luckliy) I took my own advice about moving a bunch into USD shortly after I sent this. I didn't hit the top, and I came back in too early in the summer of 2018, but I got lucky in many respects.
----------------------------------------------------------------------- Jan-4, 2018
Hey all!
I woke up this morning to ETH at a solid $1000 and decided to put some thoughts together on what I think crypto has done and what I think it will do. *******, if you could share this to your kids I’d appreciate it -- I don’t have e-mail addresses, and it’s a bit unwieldy for FB Messenger… Hopefully they’ll at least find it thought-provoking. If not, they can use it as further evidence that I’m a nutjob. 😉 Some history before I head into the future. I first mined some BTC in 2011 or 2012 (Can’t remember exactly, but it was around the Christmas holidays when I started because I had time off from work to get it set up and running.) I kept it up through the start of summer in 2012, but stopped because it made my PC run hot and as it was no longer winter, ********** didn’t appreciate the sound of the fans blowing that hot air into the room any more. I’ve always said that the first BTC I mined was at$1, but looking back at it now, that’s not true – It was around $2. Here’s a link to BTC price history. In the summer of 2013 I got a new PC and moved my programs and files over before scrapping the old one. I hadn’t touched my BTC mining folder for a year then, and I didn’t even think about salvaging those wallet files. They are now gone forever, including the 9-10BTC that were in them. While I can intellectually justify the loss, it was sloppy and underlines a key thing about cryptocurrency that I believe will limit its widespread adoption by the general public until it is addressed and solved: In cryptoland, you are your own bank, and if you lose your password or account number, there is no person or organization that can help you reset it so that you can get access back. Your money is gone forever. On April 12, 2014 I bought my first BTC through Coinbase. BTC had spiked to$1000 and been in the news, at least in Japan. This made me remember my old wallet and freak out for a couple of months trying to find it and reclaim the coins. I then FOMO’d (Fear Of Missing Out”) and bought $100 worth of BTC. I was actually very lucky in my timing and bought at around$430. Even so, except for a brief 50% swing up almost immediately afterwards that made me check prices 5 times a day, BTC fell below my purchase price by the end of September and I didn’t get back to even until the end of 2015.
In May 2015 I bought my first ETH at around $1. I sent some guy on bitcointalk ~$100 worth of BTC and he sent me 100 ETH – all on trust because the amounts were small and this was a small group of people. BTC was down in the $250 range at that point, so I had lost 30-40% of my initial investment. This was of the$100 invested, so not that much in real terms, but huge in percentages. It also meant that I had to buy another $100 of BTC on Coinbase to send to this guy. A few months after I purchased my ETH, BTC had doubled and ETH had gone down to$0.50, halving the value of my ETH holdings. I was even on the first BTC purchase finally, but was now down 50% on the ETH I had bought.
The good news was that this made me start to look at things more seriously. Where I had skimmed white papers and gotten a superficial understanding of the technology before FOMO’ing, I started to act as an investor, not a speculator. Let me define how I see those two different types of activity:
• Investors buy because the price is less than the value they see in the investment. Speculators buy because they think that someone will pay more in the future than they are paying now.
• Investors trade on information (The white paper was really well-written, had a clear technical advantage over other alternatives, and addresses a need that I can understand and value.) Speculators trade on sentiment. (Buy the rumor! Sell the news!)
• Investors usually look at the investment and themselves and can describe why they purchase in those terms (ABC-Coin provides (service) that isn’t addressed yet and matches (requirements) for an investment.) Speculators usually describe why they bought something in terms of how other people think (I think that other people think that the price will rise, so I want to get ahead of that.)
• Investors don’t necessarily check the price every day. The can, and very often I do, but it isn’t required because fundamentals don’t often change on a dime. Speculators need to be glued to a price feed, because sentiment very often changes on a dime.
• Investors like ideas, people, business plans, and market opportunities. Good ones are like Spock. Speculators like trends. They are tribal.
• Investors have a longer time horizon than speculators. In cryptoland, the notion of a “longer” time horizon is still laughably small (months) compared to traditional markets, but it certainly isn’t weeks or days or hours, which is whre speculators often live.
So what has been my experience as an investor? After sitting out the rest of 2015 because I needed to understand the market better, I bought into ETH quite heavily, with my initial big purchases being in March-April of 2016. Those purchases were in the $11-$14 range. ETH, of course, dropped immediately to under $10, then came back and bounced around my purchase range for a while until December of 2016, when I purchased a lot more at around$8.
I also purchased my first ICO in August of 2016, HEAT. I bought 25ETH worth. Those tokens are now worth about half of their ICO price, so about 12.5ETH or $12500 instead of the$25000 they would be worth if I had just kept ETH. There are some other things with HEAT that mean I’ve done quite a bit better than those numbers would suggest, but the fact is that the single best thing I could have done is to hold ETH and not spend the effort/time/cost of working with HEAT. That holds true for about every top-25 token on the market when compared to ETH. It certainly holds true for the many, many tokens I tried to trade in Q1-Q2 of 2017. In almost every single case I would have done better and slept better had I just held ETH instead of trying to be smarter than Mr. Market.
But, I made money on all of them except one because the crypto market went up more in USD terms than any individual coin went down in ETH or BTC terms. This underlines something that I read somewhere and that I take to heart: A rising market makes everyone seem like a genius. A monkey throwing darts at a list of the top 100 cryptocurrencies last year would have doubled his money. Here’s a chart from September that shows 2017 year-to-date returns for the top 10 cryptocurrencies, and all of them went up a *lot* more between then and December. A monkey throwing darts at this list there would have quintupled his money.
When evaluating performance, then, you have to beat the monkey, and preferably you should try to beat a Wall Street monkey. I couldn’t, so I stopped trying around July 2017. My benchmark was the BLX, a DAA (Digital Asset Array – think fund like a Fidelity fund) created by ICONOMI. I wasn’t even close to beating the BLX returns, so I did several things.
1. I went from holding about 25 different tokens to holding 10 now. More on that in a bit.
2. I used those funds to buy ETH and BLX. ETH has done crazy-good since then and BLX has beaten BTC handily, although it hasn’t done as well as ETH.
3. I used some of those funds to set up an arbitrage operation.
The arbitrage operation is why I kept the 11 tokens that I have now. All but a couple are used in an ETH/token pair for arbitrage, and each one of them except for one special case is part of BLX. Why did I do that? I did that because ICONOMI did a better job of picking long-term holds than I did, and in arbitrage the only speculative thing you must do is pick the pairs to trade. My pairs are (No particular order):
• ETH/XMR
• ETH/ICN
• ETH/DNT
• ETH/QTUM
• ETH/ZRX
• ETH/CFI
• ETH/OMG
I also hold PLU, PLBT, and ART. These two are multi-year holds for me. I have not purchased BTC once since my initial $200, except for a few cases where BTC was the only way to go to/from an altcoin that didn’t trade against ETH yet. Right now I hold about the same 0.3BTC that I held after my first$100 purchase, so I don’t really count it.
Looking forward to this year, I am positioning myself as follows:
• ETH will still be my core holding. It is the “deepest in the stack” crypto investment that I have. “Deep in the stack” is a programming term that gets at the idea that most software is built on other software. If you just think about your notebook, you have your OS, and programs run on that. But even inside the OS there is a stack. The bottom of your stack is the kernel, and on top of that are the drivers, protocols, and other layers that allow the programs to talk to the OS, the hard drive, the screen, the mouse, your printer, etc. You can change your mouse or printer easily. Changing things deeper in the stack becomes harder and harder. ETH is deep in the crypto stack, so is very hard to dislodge – Around 60 of the top 100 cryptocurrencies by market cap run on top of Ethereum, so getting rid of Ethereum is something that would take a long time to do.
• DNT, QTUM, ZRX, and OMG are all, to varying degrees, “deep in the stack” tokens that, once established, will be very hard to dislodge.
• That said, I am peeling away some of my holdings into USD right now, because big changes are afoot and they are going to cause market disruptions. I’m going to come right out and admit that this is speculative, but I’m also going to back it up with some non-speculative facts.
• The SEC has been sending out hundreds of subpoenas to cryptocurrency organizations over the past 3-4 months. These subpoenas are simply asking for information and nobody has been charged with any crimes or misdoings, but it is clear that the SEC is getting together information so that they can begin to regulate cryptoland. When that happens, other countries will follow, and that means:
• Some tokens will be deemed outright scams and people will be prosecuted.
• Some tokens will be deemed securities and will be regulated.
• Some tokens will not be deemed scams or securities and will continue as they have.
• Looking at this, it is clear to me that the tokens that escape prosecution and regulation should do better, but the short-term impact will be brutal and ugly. It would not surprise me at all to see a 50% drop in overall market cap within Q1-Q2, with Q1 being more likely.
• Cryptoland has always been a bit nuts, but it is more nuts now than I have ever seen it. Back in 2011-2014 it was a freaks-n-geeks show where people were all about the technology and I would sit around for a 3-day weekend installing a *nix VM on my Windows machine so that I could compile the most recent source and run a CUDA SHA-256 routine rather than thrash my CPU. If that doesn’t make sense to you, you wouldn’t have even thought about being involved.
• Now, people see Bitcoin advertisements in their Facebook feed and think “I gotta get on the BTC train!” before going to Coinbase and buying some with a credit card. They don’t know anything about crypto, and they are getting eaten alive – It is no coincidence that BTC peaked after the Thanksgiving holidays when people sat around the table and Janice got Uncle Mike and Cousin Bob all excited as she talked about going to Cancun for Christmas because of her crypto winnings. Huge amounts of fiat got transferred from newbies to BTC whales during this period, and once the whales were done, BTC had dropped from $20,000 to$12,000. It’s now back at $15,000, but for people who bought at a higher level, this sucks. As a result many have moved from BTC to ETH, with the single biggest money flow in crypto in December being the BTC à ETH flow. As a result, it’s no coincidence that ETH is at all-time highs now. The thing is, though, that even most people that moved from BTC to ETH really have no idea what they are doing. They are acting on buzzwords and emotion. They are speculators and are going to get crushed. • The stock market is quite high right now, but people are starting to worry that it is too high and that we are going to enter into a period of inflation again. This has caused gold to go up a lot the last quarter and is likely also responsible a bit for the rise in cryptos. If this view is correct, then cryptos stay stronger than if that pressure wasn’t there. If wrong, then cryptos will swing down as money exits cryptoland for more traditional markets. • I am spending most of my time and money on the arbitrage effort. The nice thing about arbitrage is that it works as the markets go up, and it works as the markets go down. When markets are too volatile, however, arbitrage can get very messy and dangerous, with each trade generating a loss instead of a profit, so I am working right now to tune the algorithms to take into account rate-of-change and add in some circuit breaker triggers. Once this is done I will expand those operations. • I am getting much more serious about systems security. • I have a Nano Ledger and recommend that anyone with >$1000 of crypto have one. The Trezor is also supposed to be good, but I haven’t used it.
• I will set up a dedicated *nix notebook that is used for nothing except my crypto work. All it takes is one keylogger to get on your PC/Mac and your crypto is gone. What is on your Nano Ledger will be OK, but they will sweep out your exchange account or Coinbase account faster than you can type. A standard Linux installation with Chrome and nothing else is as about as secure as you can get in the civilian world.
• If you don’t use LastPass or a similar password manager yet, you need to do that. Your password to LastPass should be at least 16 characters long and should not have a recognizable English word in it. If you think that “Iluvu4evah” is a secure password, you’re wrong.
• Hackers know that “4”=”for” and “u”=”you”. Writing a script to substitute those in is trivial if they want to write the script, but it’s much easier for them to download one of the many, many programs out there that already do this.
• If your password contains any string of numbers from anything that can be associated with you at any time in your life, it is insecure. Take those numbers out of the character count because they are an insignificant barrier to cracking your account.
• The good news is that you probably won’t be targeted, but if you ever mention online that you are doing anything significant in crypto, that chance increased enormously.
• *Never* talk with *anyone* about how much you have in crypto. You’ll notice that I haven’t here. There is no reason to tell even a family member how much you have unless you are sharing a tax form. Sure, you may trust them, but all it takes if for someone to overhead someone else mention at a party that a relative got into crypto a long time ago and made a bunch of money. That person can also then be subjected to the $10 hack and force you to send all your crypto to them. • Your password to LastPass (Or equivalent.) should look something like this -> 6k0jQMoziX&D#4W8 • Yes, it’s a headache. Imagine your headache, though, were you to open your account one day and find all of your money gone. Looking at my notes, I have two other things that I wanted to work into this email that I didn’t get to, so here they are: 1. Just like with free apps and other software, if you are getting something of value and you didn’t pay anything for it, you need to ask why this is. With apps, the phrase is “If you didn’t pay for the product, you are the product”, and this works for things such as pump groups, tips, and even technical analysis. Here’s how I see it. 1. People don’t give tips on stocks or crypto that they don’t already own that stock or token. Why would they, since if they convince anyone to buy it, the price only goes up as a result, making it more expensive for them to buy in? Sure, you will have friends and family that may do this, but people in a crypto club, your local cryptocurrency meetup, or online are generally not your friends. They are there to make money, and if they can get you to help them make money, they will do it. Pump groups are the worst of these, and no matter how enticing it may look, stay as far away as possible from these scams. I even go so far as to report them when I see them advertise on FB or Twitter, because they are violating the terms of use. 2. Technical analysis (TA) is something that has been argued about for longer than I’ve been alive, but I think that it falls into the same boat. In short, TA argues that there are patterns in trading that can be read and acted upon to signal when one must buy or sell. It has been used forever in the stock and foreign exchange markets, and people use it in crypto as well. Let’s break down these assumptions a bit. i. First, if crypto were like the stock or forex markets we’d all be happy with 5-7% gains per year rather than easily seeing that in a day. For TA to work the same way in crypto as it does in stocks and foreign exchange, the signals would have to be *much* stronger and faster-reacting than they work in the traditional market, but people use them in exactly the same way. ii. Another area where crypto is very different than the stock and forex markets centers around market efficiency theory. This theory says that markets are efficient and that the price reflects all the available information at any given time. This is why gold in New York is similar in price to gold in London or Shanghai, and why arbitrage margins are easily <0.1% in those markets compared to cryptoland where I can easily get 10x that. Crypto simply has too much speculation and not enough professional traders in it yet to operate as an efficient market. That fundamentally changes the way that the market behaves and should make any TA patterns from traditional markets irrelevant in crypto. iii. There are services, both free and paid that claim to put out signals based on TA for when one should buy and sell. If you think for even a second that they are not front-running (Placing orders ahead of yours to profit.) you and the other people using the service, you’re naïve. iv. Likewise, if you don’t think that there are people that have but together computerized systems to get ahead of people doing manual TA, you’re naïve. The guys that I have programming my arbitrage bots have offered to build me a TA bot and set up a service to sell signals once our position is taken. I said no, but I am sure that they will do it themselves or sell that to someone else. Basically they look at TA as a tip machine where when a certain pattern is seen, people act on that “tip”. They use software to see that “tip” faster and take a position on it so that when slower participants come in they either have to sell lower or buy higher than the TA bot did. Remember, if you are getting a tip for free, you’re the product. In TA I see a system when people are all acting on free preset “tips” and getting played by the more sophisticated market participants. Again, you have to beat that Wall Street monkey. 1. If you still don’t agree that TA is bogus, think about it this way: If TA was real, Wall Street would have figured it out decades ago and we would have TA funds that would be beating the market. We don’t. 2. If you still don’t agree that TA is bogus and that its real and well, proven, then you must think that all smart traders use them. Now follow that logic forward and think about what would happen if every smart trader pushing big money followed TA. The signals would only last for a split second and would then be overwhelmed by people acting on them, making them impossible to leverage. This is essentially what the efficient market theory postulates for all information, including TA. OK, the one last item. Read this weekly newsletter – You can sign up at the bottom.

Dabei ergeben unterschiedliche Inhalte niemals den selben Hashwert. SHA → Secure Hash Algorithm 256 → Länge des Algorithmus in Bits. Verwendung. Dieser Algorithmus wird bspw. in der Blockchain-Technologie bei Bitcoin, Peercoin und Namecoin verwendet, um den ... List of top SHA256 coins by Market Capitalization. About. Coinlore provides original cryptocurrency/coin prices calculated by own algorithm, and other metrics such as markets, volumes, historical prices, charts, coin market caps, blockchain info, API, widgets and more. Whatsminer M31 series is the newest ASIC miner for SHA-256 Algorithm by MicroBT. It can mine Bitcoin or Bitcoin cash with a hashrate of 70TH/s - 80TH/s (+-5%) and a power consumption of 3344w(+-10%). It is definitely a model that can compete with Antminer S19. For comparison, as of January 2015, Bitcoin was computing 300 quadrillion SHA-256 hashes per second. That's$300 \times 10^{15}$hashes per second. Let's say you were trying to perform a collision attack and would "only" need to calculate$2^{128}\$ hashes. At the rate Bitcoin is going, it would take them The hash calculation is documented at Block hashing algorithm.Start there for the relatively simple basics. The basic data structures are documented in Protocol specification - Bitcoin Wiki.Note that the protocol definition (and the definition of work) more or less assumes that SHA-256 hashes are 256-bit little-endian values, rather than big-endian as the standard implies.
