The choice between PoW and PoS ultimately depends on the specific eth proof of stake goals and priorities of a blockchain network. PoS is a better fit for Ethereum’s long-term roadmap of sustainability and scalability. Conversely, PoW has its merits in other blockchains like Bitcoin, where it’s necessary to securely sequence the transaction history and make it increasingly difficult to tamper with the data over time. Under Proof of Stake (PoS), Ethereum uses “checkpoint” blocks to manage validator votes.
Ethereum Proof Of Stake – Conclusion
- Once honest nodes reach a chain of length $6$, the adversary releases the withheld blocks.
- For instance, Ethereum requires 32 ETH to be staked before a user can operate a node.
- In conclusion, Ethereum’s transition to proof-of-stake has had considerable impacts on the network’s environmental footprint and financial opportunities.
- Proof-of-stake is a way to prove that validators have put something of value into the network that can be destroyed if they act dishonestly.
- Currently, the Ethereum Beacon Chain is a different network that has been running parallel to Ethereum.
This is meant to improve system efficiency and security by minimising the possibility for centralization and expanding the network’s validators (Gaži et al., 2019). Sharding is a scalability option for blockchains that allows the network to be divided into smaller sub-networks that can run in parallel. PoS is seen to be a suitable fit for sharding because it improves system security and scalability by distributing the validation process over multiple validators (Yu et al., 2020). Researchers are investigating how to utilise PoS to safeguard sharded blockchain systems, including cross-shard communication and the use of economic incentives to https://www.xcritical.com/ guarantee system security.
Phases of the Ethereum 2.0 Upgrade
Kim (2020) outlined the structural changes and impacts of Ethereum 2.0 on the market, focusing on how staking services improve participation and decentralization [20]. Additionally, Brown-Cohen et al. (2019) explored the security barriers to implementing PoS protocols, providing insights into overcoming the Decentralized application ”nothing-at-stake” problem [21]. Lido works by pooling ETH from users and then staking it on behalf of the pool. Users are then issued a token called staked ETH (stETH) which represents their share of the pool.

Fortunately, the Merge will help solve some of these environmental concerns, as it’s expected that the proof of stake model will reduce Ethereum’s energy consumption by at least 99.95%. Ethereum has been steadily gaining traction with investors over the years. The Ethereum blockchain will be switched from its current proof of work consensus to proof of stake. Among other things, this will result in huge energy savings and a smaller carbon footprint.
Proof-of-Work vs. Proof-of-Stake: Why did Ethereum Switch to Proof-of-Stake?
The oldest of the two is proof of work, which is utilized by Bitcoin, Ethereum 1.0, and many other cryptocurrencies. Proof of stake is a modern consensus method that powers Ethereum 2.0, Cardano, Tezos, and other (usually newer) cryptocurrencies. Because it’s easier to comprehend proof of stake if you first understand proof of work, we’ve combined the two in this explainer. This can increase confidence among stakeholders, not just in Ethereum but across the blockchain and cryptocurrency sectors. Knowing that they are part of a securely and fairly managed system is invaluable for users, investors, and developers. This increased trust and security could lead to broader adoption, more innovation, and a stronger, more resilient cryptocurrency ecosystem.
Alternatively, proof of stake validators have a much lower barrier of entry. As stated earlier, validators can operate effectively using a standard laptop computer and $40,000 to $50,000 of native coin. New validators can get started with even less native coin by joining a staking pool.

One of the validators in the group will act as the “block proposer,” while the others will be the “Attesters.” While the proposer initiates a block proposal, the attesters will validate it. To exploit a PoW network, a hacker will control 51% of computing power, which is impossible. But in a PoS chain, a hacker will need 51% of the total crypto on the network. While the PoW mechanisms reward participants with a new token, the Proof of stake allocates a percentage of the network transaction fees to the validators. Cosmos is a framework designed to facilitate the building of many interoperable blockchains.
For a short period that follows, a transaction may be vulnerable to attacks from bad actors who try to exploit weak points in the blockchain. Proof-of-stake is designed to reduce network congestion and address environmental sustainability concerns surrounding the proof-of-work (PoW) protocol. Proof-of-work is a competitive approach to verifying transactions, which naturally encourages people to look for ways to gain an advantage, especially since monetary value is involved. To activate your own validator, you’ll need to stake 32 ETH; however, you don’t need to stake that much ETH to participate in validation. You can join validation pools using “liquid staking” which uses an ERC-20 token that represents your ETH.
An AVS (Active Authentication Service) with an on-chain slashing contract can be protected by EigenLayer. One of the primary benefits of PoS is that it consumes less energy than PoW, as depicted in Figure 1. This is because it does not require computational effort and hence uses less energy to operate (Lashkari and Musilek, 2021). Furthermore, because users are picked to add a new block based on the quantity of tokens they own, any single miner or group of miners has a lower chance of seizing control of the network. This is due to the fact that users can stake their tokens in a variety of methods, such as through a validator or a delegator.
The challenges we’ve dissected are dynamic, ever-evolving entities, and these innovative approaches signal a promising future. Stakers can choose to delegate their stake to any operator that they trust. Operators can compete for delegators by offering competitive fees and services. Stakers can also diversify their risk by delegating to multiple operators. Stakers delegate their stake to operators by depositing their ETH into an EigenLayer delegation contract.
The PoS merge is an important milestone in the Ethereum roadmap and will help to make Ethereum more scalable, secure, and decentralized. The PoS merge is a complex process, and there are still many challenges to be overcome, but the Ethereum community has shown that it is up to the task. It’s also feasible for a staker to go rogue and approve incorrect transactions.
There is an equal percent reward and representation across the network with PoS. The authors like to acknowledge the regular updates from Vitalik Buterin on Ethereum Merge. Also special thanks to Digiconomist portal for keeping the energy consumption data open source.
Ethereum uses a blockchain, which is a distributed ledger (like a database). Information is stored in blocks, each containing encoded data from the block before it and the new information. Throughout the blockchain network, an identical copy of the blockchain is distributed. Anyone can use Ethereum—it’s designed to be scalable, programmable, secure, and decentralized—to create any secured digital technology.
Staking rewards will increase from what they are on the beacon chain as transaction fees that used to go towards mining become paid out to validation nodes. Ether could then become a much more attractive asset which would lead institutions to be interested enough in its potential return on investment. It enabled holders to stake their tokens and become validators to earn rewards.
