Ethereum switches to proof-of-stake consensus after completing The Merge

Anyone with a small amount of proof-of-stake cryptocurrency can participate in staking. The rewards might be higher for those with a bigger investment, but the roadblocks to getting started are lower than with major proof-of-work cryptocurrencies. So, to those hoping PoS Ethereum would make transactions cheaper, sorry, those gas fees will still be way too high.

This requires expensive computers and uses up a significant amount of energy. Those that verify the transaction first receive compensation in the form of coins. Proof of stake means that users can earn ether by locking their coins in to validate transactions. When you validate with your coins, it’s believed to indicate that investors are expecting profits based on the efforts of others.

What Does Proof-of-Stake (PoS) Mean in Crypto?

As part of that roadmap, the existing proof-of-work chain would eventually be deprecated via the difficulty bomb. Users & applications would migrate to a new, proof-of-stake Ethereum chain, known as Eth2. Slashing is quite a rare occurrence given the serious penalties if it does take place.

Ethereum always had, as part of its roadmap,plans to scale the network in a decentralized wayand totransition to proof-of-stake. Early on, researchers worked on these efforts separately, but around 2018 they werecombined into a single roadmap under the “Ethereum 2.0” umbrella. We strive to make staking as safe and transparent as possible, however, it’s important to consider factors that may influence whether a particular staking option is appropriate for you.


Shard chains will allow for parallel processing, so the network can scale and support many more users than it currently does. Many see the inclusion of shard chains as the official completion of the Ethereum 2.0 upgrade, but it’s not scheduled to happen until 2023. In principle, a small group of people could take the reins and switch Bitcoin to proof of stake. Since ethereum proof of stake model it is an open-source project, Bitcoin’s development relies on decisions made by the community, which in theory includes anyone who wants to participate. But the fact that the Ethereum blockchain consumes a lot less electricity is incredible news already. Many developers will now focus on rollup contracts to reduce transaction costs and enable scalability.

10,000 Bitcoin would roughly equal 200 million dollars at the time of writing this article! The point is, the value of Bitcoin is not determined by the technology itself; it is determined by what you get in exchange for it. When selecting a staking pool, it’s generally advisable to avoid choosing one with the highest or lowest network share. Delegating to the most popular staking pools can increase the risk of centralization within the network. Finding the balance and choosing a validator with a moderate network share and good reputation could be the best approach. The time you will need to wait to unstake your ETH can vary depending on the number of validators ahead of you in the withdrawal queue.

What is proof of stake?

To limit counterparty risk, the keys to withdraw your ETH are usually kept in your possession. For example, when there were only around 500,000 ETH staked, the annual percentage rate of interest was a little over 20%. By August, 2021, there were more than 6,800,000 ETH locked on the blockchain, meaning the APR had dropped to about 6.0%. Proof of stake and proof of work each have their place in the crypto world. And though people have been arguing about their relative merits for years, there’s no clear consensus on which is better.

  • When the pool of staked ETH dips, the annual interest rate increases.
  • In contrast, with proof of stake, you must control more than half the coins in the system.
  • Whether they will lead to widespread prosperity or not is up to us.
  • In fact, it was supposed to be the mechanism securing Ethereum from the start, according to the white paper that initially described the new blockchain in 2013.
  • This usually involves the network deducting some of their security deposit .
  • Oracles will support DeFi on Ethereum, not Ethereum PoW. DeFi on Ethereum PoW is dead on arrival.

Checkpoints occur at the start of each epoch and to have a supermajority link they must both be attested to by 66% of the total staked ETH on the network. If you can buy things worth 200 Bitcoin by spending the same 100 Bitcoin twice, then you might as well buy those things by spending one Bitcoin 200 times. In other words, you would be able to buy anything with tiny amounts of money! Everyone else would do the same, of course, and before long you’d have endless quarrels about what belongs to whom. In the end, people would conclude that the currency isn’t worth anything because it results in fights.


If you don’t intend to hold ETH long-term, it’s wise to keep your funds liquid. Validators are also expected to keep their nodes connected to the blockchain 24/7. After you install your validator software on your computer, the next step is to lock away a minimum of 32 ETH to the appropriate Ethereum staking contract address. These methods add new “blocks” of transactions to the historical record, and both provide a way for users to earn additional crypto.

The trade-off here is that centralized providers consolidate large pools of ETH to run large numbers of validators. This can be dangerous for the network and its users as it creates a large centralized target and point of failure, making the network more vulnerable to attack or bugs. PoS on Ethereum is also intended to lay the groundwork for “sharding” – a partitioning technique that allows multiple parallel chains to share data and transaction load efficiently.

Proof-of-stake is a cryptocurrency consensus mechanism for processing transactions and creating new blocks in a blockchain. A consensus mechanism is a method for validating entries into a distributed database and keeping the database secure. In the case of cryptocurrency, the database is called a blockchain—so the consensus mechanism secures the blockchain. A validator node is a vital part of a blockchain network, responsible for participating in the consensus-building process of a Proof of Stake blockchain.


In these roles, Andy has seen cryptocurrency develop from an experimental dark-web technology into an accepted part of the global financial system. The main upside of Proof-of-Work is that it is trusted and has a long track record while the main upside of Proof-of-Stake is that it requires less energy, is more secure, and is scalable. Investors may be familiar with Proof-of-Work protocols and have invested considerably in Proof-of-Work mining operations but likely will appreciate the reduced mining costs of Proof-of-Stake. Users of cryptocurrencies might also feel more secure using Proof-of-Stake networks and appreciate the lower ecological footprint. The adoption of lower mining footprints through Proof-of-Stake models could make more people adopt cryptocurrencies, which could help scale existing currencies. Proof-of-Work requires increasingly fast computers, the use of significant energy resources, and processes that eventually slow down transaction times as a cryptocurrency network grows.
