Plan To Cut Ethereum Energy Use Sees Miners Switch Cryptocurrencies


Ethereum’s switch from proof-of-work to proof-of-stake has been completed earlier today as officially announced by the cryptocoin’s creator Vitalik Buterin via Twitter. This is regarded as a milestone event for the Ethereum ecosystem since the required energy for maintaining the whole network should be reduced by 99%, which translates to a 0.2% overall reduction for the global electricity consumption. It would also lead to a massive GPU dump, resulting in considerable discounts, but this might not happen right away. It looks like not all the ETH miners are willing to renounce their GPU exploits to embrace the greener PoS version. With the recently completed Ethereum PoS merge, the coin would effectively become unmineable via GPUs some time in 2023. However, an immediate GPU dump is unlikely, as new PoW alternatives including Ethereum Classic or the newly-created EthereumPOW hard fork still see considerable support from certain large GPU mining players.

For afterall Blockchain is all about consensus, then why not a consensus within a larger community. And these energy costs are paid with fiat currencies, leading to constant downward pressure on the digital currency value. The Ethereum community and its creator, Vitalik Buterin, are planning to do a hardfork to make a transition from proof of work to proof of stake. The important thing you need to understand is that now Ethereum developers want to turn the tables, using a new consensus system called proof of stake.

Why Would I Want To Stake My Eth?

On the bright side, Nvidia and AMD are now offering most of the current gen GPUs at lower-than-MSRP in preparation for the next gen launches. For staking your ETH and attesting to correct blocks, you will be rewarded with additional ETH through a network wide interest rate as well as receive a portion of network transaction fees. The fourth can be recovered from via a “minority soft fork”, where a minority of honest validators agree the majority is censoring them, and stop building on their chain. Instead, they continue their own chain, and eventually the “leak” mechanism described above ensures that this honest minority becomes a 2/3 supermajority on the new chain. At that point, the market is expected to favor the chain controlled by honest nodes over the chain controlled by dishonest nodes. The discussion whether PoW is better than PoS or vice versa, with all their relative advantages and disadvantages needs to be discussed with a larger audience.

It is considered an improvement over Proof of Work because of less consumption of electricity, reduced centralization risks, security against different types of 51% attacks, and more. In a PoS-based system, bets are the transactions that, according to the consensus rules, will reward their validator with a money prize together with each chain that the validator has bet on. This way, CASPER will be a security deposit protocol that relies on an economic consensus system. Nodes must pay a security deposit in order to be part of the consensus thanks to the new blocks’ creation. Casper protocol will determine the specific amount of rewards received by the validators thanks to its control over security deposits.

If at any point your deposit drops below Ethereum Proof of Stake Model 16 ETH you will be removed from the validator set entirely. Reduced centralization risks, as economies of scale are much less of an issue.

The creators of the ETHW chain intend to copy the entire original ETH blockchain complete with tokens, NFTs, DApps and even liquidity pools. However, for the time being, there are very few DApp operators and ETHW is not backed by any stablecoin, unlike Ethereum Classic, so its value remains highly speculative. ETHW still managed to get the support of TRON’s founder and established crypto exchange platforms like Poloniex and BitMEX.

I’m also an avid reader of science fiction, an astrophysics aficionado, and a crypto geek. I started writing PC-related articles for Softpedia and a few blogs back in 2006. I joined the Notebookcheck team in the summer of 2017 and am currently a senior tech writer mostly covering processor, GPU, and laptop news.

Proof of Stake is a category of consensus algorithms for public blockchains that depend on a validator’s economic stake in the network. In Proof of Work based public blockchains (e.g. Bitcoin and the current implementation of Ethereum), the algorithm rewards participants who solve cryptographic puzzles in order to validate transactions and create new blocks (i.e. mining). In PoS-based public blockchains (e.g. Ethereum’s upcoming Casper implementation), a set of validators take turns proposing and voting on the next block, and the weight of each validator’s vote depends on the size of its deposit (i.e. stake). Significant advantages of PoS include security, reduced risk of centralization, and energy efficiency. The blockchain keeps track of a set of validators, and anyone who holds the blockchain’s base cryptocurrency (in Ethereum’s case, ETH) can become a validator by sending a special type of transaction that locks up their ETH into a deposit.

The Proof of work concept existed even before bitcoin, but Satoshi Nakamoto applied this technique to his/her – we still don’t know who Nakamoto really is – digital currency revolutionizing the way traditional transactions are set. In this article, I will explain to you the main differences between Proof of Work vs Proof of Stake and I will provide you a definition of mining, or the process new digital currencies are released through the network. To participate in voting (i.e. to become a validator) you are required to stake ETH for which you’ll be rewarded with additional ETH at some interest rate in addition to receiving a portion of the network transaction fees. So, Casper is based on the idea that validators will bet according to the others’ bets and leave positive feedbacks that are able to accelerate consensus.

The process of creating and agreeing to new blocks is then done through a consensus algorithm in which all current validators can and are expected to participate. A radical update last week to the Ethereum cryptocurrency was supposed to reduce energy consumption by 99 per cent, but the savings have so far failed to materialise as miners evicted from the network flock to other currencies. Estimates suggest that at least 50 per cent of energy hungry mining hardware formerly running Ethereum has now been put to use mining other coins. Proof of Stake represents a class of consensus algorithms in which validators vote on the next block, and the weight of the vote depends upon the size of its stake.

What Are The Hardware Requirements To Run This Software?

Thanks to a PoS system validators do not have to use their computing power because the only factors that influence their chances are the total number of their own coins and the current complexity of the network. Instead, the underlying PoS algorithm must be as bulletproof as possible because, without especially penalties, a proof of stake-based network could be cheaper to attack. This process will be available through a function of calling the Casper contract and sending Ether – or the coin who powers the Ethereum network – together with it. Proof of work is not only used by the bitcoin blockchain but also by ethereum and many other blockchains. A trustless and distributed consensus system means that if you want to send and/or receive money from someone you don’t need to trust in third-party services.

Stores canonical state, handles peers and incoming sync, propagates blocks and attestations. The reward of each validator will be “somewhere around 2-15%, ” but he is not sure yet. “You automatically get inducted after some time,” explained Vitalik Buterin himself on a post shared on Reddit.

When a miner finally finds the right solution, he/she announces it to the whole network at the same time, receiving a cryptocurrency prize provided by the protocol. To create new digital currencies by rewarding miners for performing the previous task. With bitcoin and a few other digital currencies, everyone has a copy of the ledger , so no one has to trust in third parties because anyone can directly verify the information written.

Tracks shared state execution data and data blobs that the validator has signed.

Train To Become A Blockchain Developer

To solve this issue, Buterin created the Casper protocol, designing an algorithm that can use the set some circumstances under which a bad validator might lose their deposit. Developers are pretty worried about this problem, and the ethereum community wants to exploit the proof of stake method for a more greener and cheaper distributed form of consensus. Following that, the validators bet on the blocks that they feel will be added next to the chain. When the block gets added, the validators get a block reward in proportion to their stake.

Entry barriers with PoW are high so not anyone can just join the network to validate the transactions which can be the case with PoS. In fact, PoW idea was originally published by Cynthia Dwork and Moni Naor back in 1993, but the term “proof of work” was coined by Markus Jakobsson and Ari Juels in a document published in 1999. Help.coinbase.com needs to review the security of your connection before proceeding. For example, if the current interest rate is 5%, you would lose 0.0137% of your deposit every day, but gain that for every day you’re online.

What Is Proof Of Stake

Some functions of the proof of work system are different because created specifically for each blockchain, but now I don’t want to confuse your ideas with too technical data. I first stepped into the wondrous IT&C world when I was around seven years old. I was instantly fascinated by computerized graphics, whether they were from games or 3D applications like 3D Max.

While the overall process remains the same as proof of work , the method of reaching the end goal is entirely different. In POW, the miners solve cryptographically hard puzzles by using their computational resources. But, returning to date, Proof of work is maybe the biggest idea behind the Nakamoto’s https://xcritical.com/ bitcoin white paper – published back in 2008 – because it allows trustless and distributed consensus. Note that blocks may still be chained together; the key difference is that consensus on a block can come within one block, and does not depend on the length or size of the chain after it.

When you use traditional methods of payment, you need to trust in a third party to set your transaction (e.g. Visa, Mastercard, PayPal, banks). They keep their own private register which stores transaction history and balances of each account. Ability to use economic penalties to make various forms of 51% attacks vastly more expensive to carry out than Proof of Work.

How Long Is My Ether Locked Up If I Stake?

To paraphrase Vlad Zamfir, “it’s as though your ASIC farm burned down if you participated in a 51% attack”. Also, Buterin argued that there will be no imposed limit on the number of active validators , but it will be regulated economically by cutting the interest rate if there are too many validators and increasing the reward if there are too few. In recent research, experts argued that bitcoin transactions may consume as much electricity as Denmark by 2020. In fact, programming an attack to a PoW network is very expensive, and you would need more money than you can be able to steal. Any computer system wants to be free from the possibility of hacker attacks, especially if the service is related to money. Cyber-attacks such as a distributed denial-of-service attack which has the purpose of exhausting the resources of a computer system by sending multiple fake requests.

In the first case, users can socially coordinate out-of-band to agree which finalized block came first, and favor that block. The second case can be solved with fraud proofs and data availability proofs. The third case can be solved by a modification to PoS algorithms that gradually reduces (“leaks”) non-participating nodes’ weights in the validator set if they do not participate in consensus; the Casper FFG paper includes a description of this. Because of the lack of high electricity consumption requirements there is not as much need to issue as many new coins in order to motivate participants to keep participating in the network. It may theoretically even be possible to have negative net issuance, where a portion of transaction fees is “burned” thus decreasing the supply over time. If one validator creates an “invalid” block, his security deposit will be deleted, as well as his privilege to be part of the network consensus.

In a distributed consensus-based on the proof of Work, miners need a lot of energy. One Bitcoin transaction required the same amount of electricity as powering 1.57 American households for one day . Even though Ethereum Classic already exists as a PoW alternative to the main ETH chain, a new hard fork named EthereumPOW has recently been created for GPU miners.

The problem with copying the original Ethereum chain is that ETHW now includes the difficulty bomb that would make GPU mining useless some time in 2023. ETHW is not yet available as a coin, yet its IOU valuation is already trading at ~US$30. With quite a few GPU miners planning to continue supporting Ethereum Classic, EthereumPOW or whatever PoW coin emerges more profitable, the highly-anticipated GPU flood that would finally put an end to the inflated prices could be postponed.
