Pros and Cons of Proof of Stake for Ethereum Blockchain Security

In addition, liquid staking also enables users to hold custody of their assets in their own ETH wallet. Subsequently, validators could receive rewards upon verifying a new block or randomly selecting to create the next block. Validators in the Proof of Stake system could have better chances of earning rewards on the basis of their stake.

Multiple validators are involved in verifying each block, which involves some simple calculations. If a positive consensus is reached, the block and its transactions are accepted onto the blockchain, simply put. Most experts agree that The Merge will affect the cryptocurrency market. According to Glassnode, Ethereum-based derivatives traders are positive about the price of ETH in September 2022. Based on the ratio of calls and puts, as well as OI indicators, investors are betting on the price from $2,200 to $5,000. As of June 2022, the energy consumption of the Ethereum blockchain was 112 TWh per year, which was comparable to the consumption of a medium-sized country.


Proof-of-stake will be a financial incentive against the temptation to validate fraudulent transactions. Since the stake will always be higher than the promised financial rewards, a fraudulent validator risks losing more funds than they would gain through fraud. No validator will want to participate in fabrication at the risk of losing the massive amount of crypto assets they have staked. The proof-of-stake solves scalability issues that have been a thorn in the flesh in the proof-of-work consensus mechanism.

Even if that means the ETH securing the network is more centralized for now, he doesn’t think it will discourage developers from actually building on Ethereum. At the moment, staked ETH cannot be withdrawn, but that is scheduled to change with Shanghai, the next network update. Even if a validator’s MEV-boost relay excludes transactions to stay compliant with OFAC sanctions, there is a validating step that takes place to help guard against censorship.


Investopedia makes no representations or warranties as to the accuracy or timeliness of the information contained herein. Blocks are validated by more than one validator, and when a specific number of the validators verify that the block is accurate, it is finalized and closed. To become a validator, a coin owner must “stake” a specific amount of coins.

After the merge, subsequent upgrades will increase the capacity and speed of the network by introducing “shard chains.” These will expand the network to 64 blockchains. The merge needs to happen first because these shard chains rely on staking. The fact that one of the major crypto players invested time and money laying the groundwork for a less destructive and more efficient ecosystem is an enormous achievement. That signal alone may prove transformative for the Web3 industry, which is still getting steady VC investment and could find new fuel in buoyed public perception.

Ethereum Proof-of-Stake Consensus Specifications

Currently, a validator can expect to earn a 4-4.5% yield on their holdings in the PoS pool. The Ethereum network has gone through a critical upgrade called The Merge, which involved changing the consensus algorithm from Proof-of-Work to Proof-of-Stake . The upgrade is meant to make the blockchain platform more scalable, secure, and decentralized. For individual investors, proof of stake cryptocurrencies offer a lower cost and more efficient method to buy, sell, and trade currencies. That makes them more useful for everyday transactions than currencies that rely on proof of work. Almost four months after Ethereum’s successful shift to a proof-of-stake network, the second-biggest blockchain has passed another major milestone.

For the casual crypto investor, the difference between proof of work and proof of stake isn’t as important as many other core metrics and considerations. Things like trading history, market capitalization, and price provide more valuable information to investors looking to make smart decisions about what cryptos to invest in or to take a pass on. Proof of stake offers key advantages compared to proof of work, experts say. Its faster transaction speeds and more efficient energy requirements allow for blockchains that are more scalable and thus easier to find more adoption among new users.

Merge shifts Ethereum to full proof-of-stake, price slumps

As of January 2016, the Ethereum protocol could process about 25 transactions per second; this didn’t change after the proof-of-stake implementation. In comparison, the Visa payment platform processes 45,000 payments per second. On 19 December 2016, Ethereum exceeded one million transactions in a single day for the first time. Visa has also signaled interest in processing NFT and Ethereum transactions. The staking pool’s owner sets up the validator node, and a group of people pool their coins together for a better chance of winning new blocks.

  • Most recently, ether fell some 8% on April 11 after an Ethereum lead developer said plans for the event set for June had been pushed back as tests on the software continued.
  • If so, they add the block to the blockchain and receive crypto rewards for their contribution.
  • Every committee follows a specific time for the proposal of a new block alongside the validation of transactions within them.
  • This work was done by Gavin Wood, then the chief technology officer, in the Ethereum Yellow Paper that specified the Ethereum Virtual Machine.
  • The Ethereum Virtual Machine is the runtime environment for transaction execution in Ethereum.
  • 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.

The proof-of-stake system brings versatility that fits into more use cases. Most other security features of PoS are not advertised, as this might create an opportunity to circumvent security measures. However, most PoS systems have extra security features in place that add to the inherent security behind blockchains ethereum speedier proofofstake and PoS mechanisms. Validators are selected randomly to confirm transactions and validate block information. This system randomizes who gets to collect fees rather than using a competitive rewards-based mechanism like proof-of-work. Cardano ADA and Solana SOL are already using the proof-of-stake method.

Pros and cons of proof of stake in crypto

This method of verifying blockchain transactions could solve crypto’s environmental impact. This “proof-of-work” consensus mechanism, which requires computers to agree on which transactions will be added to a new block, is very energy-intensive. While some people have already embraced the Merge and its positive aspects, others are still confused about the proof-of-stake mechanism. Our article will dissect the advantages and disadvantages of the transition to the PoS consensus mechanism and what it means to blockchain security. Algorand is a cryptocurrency and blockchain platform that can finalize transactions immediately. A 51% attack is an attack on a blockchain by a group of miners who control more than 50% of the network’s mining hash rate, or computing power.

When you stake more ETH in the network, hackers would need additional ETH to control the majority. If any individual wants to compromise the Ethereum blockchain in any way, they would need control over the majority of the ETH. Proof of stake requires multiple validators to agree that a transaction is accurate, and once enough nodes verify the transaction, it goes through.

Each node connects with a relatively small subset of the network—its “peers”. It offers validated blocks and unvalidated transactions (i.e. transactions not yet in the blockchain) to its peers for download, and it downloads any of these from its peers that it doesn’t already have. In more precise terms, proof-of-work and proof-of-stake are both types of consensus mechanisms that are designed to solve the issue of trust between the participants of a blockchain network. The Beacon Chain made it possible to coordinate the work of validators and their distribution among shards. The algorithm implements segment synchronization and opens access to information about the current state of the network.

Anyone who has been in the crypto space even for a short while is familiar with the name Ethereum. The second-largest cryptocurrency after Bitcoin and a blockchain home to numerous NFTs and DeFi projects, Ethereum has branched into digital money, global payments, as well as applications. Ethereum’s blockchain uses Merkle trees for security reasons, to improve scalability, and to optimize transaction hashing. As with any Merkle tree implementation, this allows for storage savings, set membership proofs (called “Merkle proofs”), and light client synchronization. The network has faced congestion problems, such as in 2017 in relation to CryptoKitties. The first of these three upgrades, also known as “phase 0”, launched the proof-of-stake Beacon Chain on the 1st of December, 2020.

It does this by starting with the genesis state and executing every transaction in the blockchain, in the proper order of blocks and in the order they are listed within each block. The cryptocurrency Ether is a high-profile example of a project that is currently in the process of migrating away from proof-of-work blockchain toward proof-of-stake blockchain. In proof-of-work blockchain, majority decision is represented by the “longest-chain-wins” rule. This means that participants in the blockchain network accept the longest chain of blocks as being the only valid one.

So when something happens to ethereum, it impacts the entire cryptocurrency space. One of the primary goals of the Ethereum community is to make the platform more secure for investors and developers. In the past, we have seen several hacking incidents on different blockchains that resulted in people losing their money. Moving towards a PoS system, at least in theory, will minimize the risk of cyberattacks. One issue related to using smart contracts on a public blockchain is that bugs, including security holes, are visible to all but cannot be fixed quickly. One example of this is the 2016 attack on The DAO, which could not be quickly stopped or reversed.

Make Sunsets is already attempting to earn revenue for geoengineering, a move likely to provoke widespread criticism. Rebecca Ackermann is a writer, designer, and artist based in San Francisco. She wrote about the promises of crypto and Web3 for MIT Technology Review’s Money Issue earlier this year. It would be hard to overstate how much industry excitement there has been around this shift. Many hope it can both rehabilitate the reputation of crypto for skeptics and improve the efficiency of Ethereum’s enormous ecosystem of businesses and developers.

Centralized exchanges are an ideal choice for beginners in staking as they can help in earning reasonable yields on their ETH stake with limited efforts and oversight. On the other hand, it is also important to notice the trade-offs that come with centralized exchanges. On top of it, you must have a dedicated computer solely for staking and ensure that it remains connected to the internet around the clock. In addition, you need technical know-how of staking and blockchain mechanics. At the same time, users can rely on easy-to-use tools to simplify the process. ETH staking guide showcase how Ethereum staking is an inevitable aspect of the new ETH 2.0.

How Do You Earn Proof-of-Stake?

Ethereum investors are concerned after the head of the SEC, Gary Gensler, indicated that the cryptocurrency could be considered a security now just a day after the merger. Gensler’s comments on the staking rewards were, “From the coin’s perspective, that’s another indication that under the Howey Test, the investing public is anticipating profits based on the efforts of others.” The major issue with mining crypto is the amount of energy required to verify transactions on blockchains that require proof of work. Ethereum decided to shift from the energy-intensive proof-of-work to the more environmentally friendly proof-of-stake system. The Ethereum Foundation has claimed that the transition reduced Ethereum’s energy consumption by 99.95%. A major criticism of cryptocurrency is that it has a negative impact on the environment.
