The Bitcoin Cash network has now been upgraded to support the new difficulty adjustment algorithm!

Welcome to the future!

Bitcoin Cash's new difficulty adjustment might cause problematic periodic slowdowns of the network

Is I understand it, Bitcoin Cash expanded the algorithm for difficulty adjustment: if there are less than 6 blocks in 12h, difficulty gets reduced by 20%. The old 2016 block difficulty adjustment still applies.
I haven't looked at the code, but I didn't see anyone mention a rule for difficulty increase if there are too many blocks. This asymmetry could be used by the miners to increase their profits.
New strategy for miners: At the start of each 2016 block period miners stop/reduce mining to create less than 6 blocks in 12h. Difficulty gets decreased by 20% for the next ~2 week period. Miners lose ~3.6% (0.5d/14d) of profits for not mining in the first 12h, but they get a 25% (1/0.8 - 1) increase in profit for the rest of the period. With a constant hash rate 2016 blocks would be created in ~11.7 days (0.5d+14d*0.8) instead of in 14 days.
Negative effects: * at the start of each 2016 period, network would stop to a crawl * inflation would increase by 20+% (currently, on BTC, transaction fees account for only 5-10% of payments to miners, 90+% is from block creation/inflation)
Of course they could do this for more than 12h and get a bigger difficulty decrease.
All the miners benefit from this. You don't get any extra profit from being a "scab" and they could even get back the 3.6% by just mining other coins. At least 92% of miners would need to stop mining. That seems like a lot, but not impossible/unlikely.
Did I miss anything? Would this be an optimal strategy for miners? Are we gonna have to be careful when sending transactions to not get stuck in first 12*x hours slowdown every 2016 blocks?
tl;dr: miners can make extra 20+% profits by slowing down mining every 2 weeks.

Scalenet and Testnet4 are online and open for business

Over the years, some people have made use of testnet3 to test out scaling performance, and have spammed testnet3 with 32 MB blocks. This has caused testnet3 to get kinda bloated; the blockchain now takes an hour or so to sync, which slows down development. Other people have wanted to do stress testing, but have specifically wanted to avoid inconveniencing other people by spamming testnet3, and have therefore not done so. This slows down development too. To address this issue, I created two new networks: testnet4 and scalenet.
Testnet4 is intended to be a low-volume quick-syncing blockchain which is ideal for testing out new transaction formats or applications. It has a 2 MB default block size limit, and comes with aserti3 parameters that make the difficulty recover quickly to CPU-mineable levels. It should remain easy to sync on a low-end VPS or old laptop.
Scalenet is intended to be a high-volume blockchain which is ideal for spamming and stress testing software. It comes with a 256 MB initial default block size limit, and uses aserti3 parameters that make it more suitable for accurately simulating mainnet mining difficulty (though it retains the 20-minute difficulty rule). In order to prevent storage costs from getting unreasonable for a testnet, scalenet will be reset every 6-12 months by invalidating the block at height 10,001 and adding a new checkpoint. Scalenet is intended to be feasible to run on a mid-range desktop computer with some strain.
Testnet4 and scalenet are now online and essentially complete. The code for both has been merged into BCHN and Electron Cash. Testnet4 has also been successfully synced to by Knuth, Bitcoin Unlimited, and libbitcoincashj. Block explorers for both are available, thanks to Axel Gembe (who runs the code) and sickpig (who wrote the code):
http://tbch4.loping.net:3002/
http://sbch.loping.net:3003/
The testnet4 and scalenet MRs were opened on Aug 19th and Aug 27th, and both were merged on Sep 17th. Scalenet reached height 10,000 on October 3rd.
Testnet4 and Scalenet support are present in the master branch of BCHN, and will be included in the next release of BCHN. Some other software (e.g. Electron Cash) already has support in their latest release, but most is still pending.

[HALVING MEGATHREAD] Block 630000 has been mined. Mining subsidy is now 6.25 BTC per block. The third Bitcoin Halving is now complete!

As of now, 630,000 blocks have been mined on the Bitcoin network, and the block reward has successfully halved for the second THIRD time. The previous block reward was 12.5 BTC, and the new block reward is now 6.25 BTC. Since the previous halving at Block 420000, monetary inflation decreased from 4.17%% to 3.57%. Block 630000 signals an immediate 50% reduction to 1.79%. The next halving will occur at Block 840000 in approximately four years. Godspeed, Bitcoin!

Gridcoin 5.0.0.0-Mandatory "Fern" Release

https://github.com/gridcoin-community/Gridcoin-Research/releases/tag/5.0.0.0
Finally! After over ten months of development and testing, "Fern" has arrived! This is a whopper. 240 pull requests merged. Essentially a complete rewrite that was started with the scraper (the "neural net" rewrite) in "Denise" has now been completed. Practically the ENTIRE Gridcoin specific codebase resting on top of the vanilla Bitcoin/Peercoin/Blackcoin vanilla PoS code has been rewritten. This removes the team requirement at last (see below), although there are many other important improvements besides that.
Fern was a monumental undertaking. We had to encode all of the old rules active for the v10 block protocol in new code and ensure that the new code was 100% compatible. This had to be done in such a way as to clear out all of the old spaghetti and ring-fence it with tightly controlled class implementations. We then wrote an entirely new, simplified ruleset for research rewards and reengineered contracts (which includes beacon management, polls, and voting) using properly classed code. The fundamentals of Gridcoin with this release are now on a very sound and maintainable footing, and the developers believe the codebase as updated here will serve as the fundamental basis for Gridcoin's future roadmap.
We have been testing this for MONTHS on testnet in various stages. The v10 (legacy) compatibility code has been running on testnet continuously as it was developed to ensure compatibility with existing nodes. During the last few months, we have done two private testnet forks and then the full public testnet testing for v11 code (the new protocol which is what Fern implements). The developers have also been running non-staking "sentinel" nodes on mainnet with this code to verify that the consensus rules are problem-free for the legacy compatibility code on the broader mainnet. We believe this amount of testing is going to result in a smooth rollout.
Given the amount of changes in Fern, I am presenting TWO changelogs below. One is high level, which summarizes the most significant changes in the protocol. The second changelog is the detailed one in the usual format, and gives you an inkling of the size of this release.

Highlights

Protocol

Note that the protocol changes will not become active until we cross the hard-fork transition height to v11, which has been set at 2053000. Given current average block spacing, this should happen around October 4, about one month from now.
Note that to get all of the beacons in the network on the new protocol, we are requiring ALL beacons to be validated. A two week (14 day) grace period is provided by the code, starting at the time of the transition height, for people currently holding a beacon to validate the beacon and prevent it from expiring. That means that EVERY CRUNCHER must advertise and validate their beacon AFTER the v11 transition (around Oct 4th) and BEFORE October 18th (or more precisely, 14 days from the actual date of the v11 transition). If you do not advertise and validate your beacon by this time, your beacon will expire and you will stop earning research rewards until you advertise and validate a new beacon. This process has been made much easier by a brand new beacon "wizard" that helps manage beacon advertisements and renewals. Once a beacon has been validated and is a v11 protocol beacon, the normal 180 day expiration rules apply. Note, however, that the 180 day expiration on research rewards has been removed with the Fern update. This means that while your beacon might expire after 180 days, your earned research rewards will be retained and can be claimed by advertising a beacon with the same CPID and going through the validation process again. In other words, you do not lose any earned research rewards if you do not stake a block within 180 days and keep your beacon up-to-date.
The transition height is also when the team requirement will be relaxed for the network.

GUI

Besides the beacon wizard, there are a number of improvements to the GUI, including new UI transaction types (and icons) for staking the superblock, sidestake sends, beacon advertisement, voting, poll creation, and transactions with a message. The main screen has been revamped with a better summary section, and better status icons. Several changes under the hood have improved GUI performance. And finally, the diagnostics have been revamped.

Blockchain

The wallet sync speed has been DRASTICALLY improved. A decent machine with a good network connection should be able to sync the entire mainnet blockchain in less than 4 hours. A fast machine with a really fast network connection and a good SSD can do it in about 2.5 hours. One of our goals was to reduce or eliminate the reliance on snapshots for mainnet, and I think we have accomplished that goal with the new sync speed. We have also streamlined the in-memory structures for the blockchain which shaves some memory use.
There are so many goodies here it is hard to summarize them all.
I would like to thank all of the contributors to this release, but especially thank @cyrossignol, whose incredible contributions formed the backbone of this release. I would also like to pay special thanks to @barton2526, @caraka, and @Quezacoatl1, who tirelessly helped during the testing and polishing phase on testnet with testing and repeated builds for all architectures.
The developers are proud to present this release to the community and we believe this represents the starting point for a true renaissance for Gridcoin!

Summary Changelog

Accrual

Changed

Most significantly, nodes calculate research rewards directly from the magnitudes in EACH superblock between stakes instead of using a two- or three- point average based on a CPID's current magnitude and the magnitude for the CPID when it last staked. For those long-timers in the community, this has been referred to as "Superblock Windows," and was first done in proof-of-concept form by @denravonska.

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.

1.1 OVERVIEW ABOUT ARYACOIN

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.
5. Business Partner with Simplex
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.

2.1 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.

Why Ethereum Mining?

1. High market capitalization, second to bitcoin only
Ethereum is the most dynamic blockchain platform in the world, and Ether is the second largest cryptocurrency in the world by market capitalization. There are around 1,200,000 transactions processed per day on this platform. Numbers explain everything.
https://preview.redd.it/w57fpy6njvp51.png?width=398&format=png&auto=webp&s=dbac1c20eaa78a503b71c8f667b12293f9079208
2. Dapps on Ethereum outnumbers any other blockchain platform
Not only just a digital currency or commodity, ethereum also keeps its original motivation to be a global computing platform that allows users to deploy smart contract on it. As a kind of smart contract programmed for a specific use, there are about 2 ,000 decentralized applications, or dapps, deployed on ethereum by this June, which is more than the total numbers of dapps deployed on any other general purpose blockchain platform in the world combined.

3. Considerable payback
ETH mining profit basically consists of two parts: the value of the coins and the transaction commission. Once you mined a block, you will not only get the coins, but also the commission to prove the transactions that will be processed in the network. Because of the network congestion brought up by DeFi application ‘s popularity, transaction commission contributes much to the mining profit recently.
(Averages on 17th September,2020:
Ether Price: $389.49
Gas Price: 538 Gwei
Gas Limit:12,472,107
*Commission=538*12472107=6,709,993,566Gwei≈6.71ETH)

Below is a profitability ranking of ASIC miners for some mainstream crypto coins when Gas price is around 60~70Gwei and coin price is about $360. I couldn’t find a ranking that could include all AISIC miners and GPU miners, but it’s enough to show that ETH mining is much more profitable than others. Even though when Gas price and coin price is not very high, the revenue of ETH mining still beats other mainstream cryptocurrencies.

4. Lower Network Difficulty
Compare to bitcoin network hash rate, Ethereum network hash rate is only 244.14TH/s; Less network hash rate means less difficulty, furtherly means that there will be more chance to mine a block and get coins. Nowadays, for bitcoin mining, the possibility to mine a block solo is almost zero, but for ETH mining it is still possible. In my opinion it is the golden time for ETH mining.

Whether you are a new bird or an experienced senior in this field, ETH mining is the best choice in 2020.
