Ethereum Swears It’ll Actually Move To Proof Of Stake This Time


But proof-of-stake is an alternative that could upend the crypto status quo. Proof of work and proof of stake are the two most widespread consensus mechanisms in the blockchain. A consensus mechanism is a method of reaching an agreement between the participants of a decentralized system. Key cryptocurrencies use POW and POS methods to protect the chain and inspect the transaction.

Proof of Stake is a mining algorithm that is based on the stake of the miner in the given ecosystem unlike arithmetic difficult puzzle in Proof of Work . That means, who writes the next block is decided based on how large the stake of a person / miner holds (i.e. how many coins or tokens does it hold). The advantage of this approach is that you maintain control over your coins, and it is relatively easy to get started staking.

Proof of Stake vs. Proof of Work

Cryptocurrencies like bitcoin currently use the proof-of-work consensus protocol. PoW is a competitive process in whichminers competeto solve a computationally hard problem to add new blocks to the blockchain. PoW uses considerable energy and is therefore costly.

What Is Pow?

Ethereum was purely based on Proof-of-Work only up until December 2020 when its blockchain, based on Proof-of-Stake, called “Beacon Chain” was created. The Proof-of-Work and Proof-of-Stake based Ethereum are referred to as Ethereum 1.0 and Ethereum 2.0 respectively. And after The Merge, we can expect that there will be people who don’t like the idea of an even more centralized blockchain, and will remain on the more dirty chains.

Aside from that, PoW is also more battle-tested, having been the backbone of bitcoin – the largest and most widely known cryptocurrency – since its inception. The main difference between POW and POS relates to how they determine who is responsible for inspecting transaction blocks. A Mathematical puzzle is normally a puzzle that requires a lot of computational energy to solve the same. The answer to the PoW problem or mathematical equation is called a hash . In summary, staking is a way of participating in the process of updating a ledger of a transaction by putting your funds at stake and earning rewards for your contribution.

When a new block of transactions arrives, the PoS protocol will randomly select a validator from the validator set to review the block. If the block is valid, it is added to the blockchain once other validators in the network have attested (i.e., confirmed) it. The validator then receives yield on their staked proportion of ETH for their participation. Validators can also be penalised for submitting fraudulent transactions, going offline, or deliberately colluding. This creates a natural incentive for validators to avoid such activity.

Bitcoin miners use specific chips designed specifically for hashing. The current hash rate of bitcoin is around 20 hash per second i.e. The chain would fork again multiple times, leaving some trading on the old versions and others on the new. It’s easy to see users jumping ship, using a new fork, or otherwise going back to older blockchains. All that would largely defeat the purpose of trying to make a cleaner, more reliable blockchain.

Proof of stake is the most popular alternative to PoW. As a consensus mechanism, PoS aims to mitigate some of the disadvantages of PoW, such as scalability and energy use. Scott Nadal and Sunny King created PoS to develop a more scalable consensus mechanism that would use less electricity.

What Is Proof Of Stake?

Randomization is taken into account when it comes to forging, this is to eliminate the possibility of favoring a single node, or entity. Other factors that are also taken into consideration (of who’s going to win the contest) are how much funds are staked, as well as how long will they be staked for. For the disadvantages of Mining mentioned above, an alternative consensus mechanism – Staking – has been introduced. As you can see, acquiring high-performance computers can easily break the bank. Also, keeping them running 24/7 just to solve mining’s mathematical problems can easily rack up miners’ electricity bills. Proof-of-stake is an alternative consensus protocol to proof-of-work .

  • In PoS, validators are randomly selected from the set of possible validators , with the probability of being selected increasing with the amount staked.

Here’s to give you an idea of how much you can be potentially rewarded shall you choose to stake Ethereum. Many newly-introduced coins out there are already embracing Proof-of-Stake. Amongst are coins like Cardano, Solana, Polkadot, Tezos, Harmony, and so on. While Proof-of-Work seems like a reliable, secure, and legit solution to manage a decentralized ledger, it is also a very resource-intensive one. If you have been in the cryptocurrency ecosystem for a while, terms like Proof-of-Work and Proof-of-Stake shouldn’t be foreign to you, or you should have at least heard of them.

Due to specific hardware requirements, most of the miners are currently based in China as it offers high-speed chips that are required for good mining. There are multiple kinds of consensus algorithms in Blockchain Technology which currently exists. Let’s know the difference between two of them Proof of Stake and Proof of Work. Staking pools are groups of people coming together, each depositing their desired staking amount, to get better chances at forging the next block. To go with this approach, it is also important to do your due diligence on the particular pool.

What Does the Merge Mean For Me?

With ethereum planning to switch to proof-of-stake, hopeful validators are staking an increasing amount of ETH . In this article, we explain how PoS works and how it differs from the more traditional PoW consensus that coins like bitcoin currently use. We will draw on ethereum as an underlying example given it plans to move to PoS consensus after the Merge in Q – an event we think willconsiderably impactethereum’s outlook. PoW and PoS are the most popular consensus mechanisms used in the blockchain. This article will explain the consensus mechanism, describe PoS and PoW, and explain their differences.

Want to have skin in the game but are concerned with some of the limitations mentioned above? Well, fret not, there are some alternative ways to stake Ethereum and earn rewards without having to run your own nodes, or forking out 32 ETH. In Mining, users mine with their computers to gain rewards; and in Staking, users Ethereum Proof of Stake Model stake their coins to gain rewards. And billions invested in coins on the Ethereum blockchain at stake, you can bet there’s going to be controversy. That’s when those sitting like royalty at the top of the Ethereum blockchain say they’ll finally move their proof-of-work-based blockchain system over to proof-of-stake.

Proof-of-stake is a consensus protocol that moves away from the competitive proof-of-work model to a wealth-based model. In PoS, only entities that stake a significant number of coins can add new blocks to the blockchain. PoW requires hashing millions of values every minute to get the desired result.

Lastly, you can also stake Ethereum via a third-party validator, also known as Validator-as-a-service. These companies will allow you to run your own validator on their servers, without the need to worry about the technicalities of setting up and maintenance. Only 900 new validators are accepted each day, the rest will have to wait in a queue.

This is why Ethereum’s transition requires so many validators to sign off and agree on a date. Node operators, those whose computers manage the chain, also need to be notified when to switch over, in order to make sure everything goes smoothly. However, a 51% attack is unlikely to materialise with a cryptocurrency like ethereum for several reasons. Firstly, the total value staked is currently around $35bn, so a 51% attack would require someone to own over $17.5bn in staked ETH – that is a lot of money.

This allows them to control the network and monopolise the mining of new blocks. Such an attack still presents a risk in PoS, except it would require owning over 50% of the total value staked. This is arguably more practical than being able to control over 50% of the hash rate of a PoW cryptocurrency.

However, just based on developers messages and blogs, there seems to finally be a true push from all the stakeholders involved toward the transition. It’s a task as complicated as transplanting the Empire State Building from Manhattan to the Moon. There are so many nodes, developers, stakeholders, and even regular holders who are all getting say in the proceedings. The PoS model is poised to take over the crypto world.
