After The Merge, the Beacon Chain became the consensus engine for all network data, including execution layer transactions and account balances. Meanwhile, any bad actor wishing to gain control over the network would need to own more than 51% of the coins staked at that time. Controlling 51% of all staked coins on the network is so difficult that it makes such an attack extremely unlikely. This is how the consensus mechanism that secures Proof of Stake networks works. You can read more about the terminology, but the point is that transactions and applications will still continue as normal on Ethereum, maintained by the same software clients we use today. However, instead of Proof of Work mining, this execution data will be confirmed by the Proof of Stake consensus layer.

Ethereum’s proof-of-stake system is already being tested on the Beacon Chain, launched on December 1, 2020. So far 9,500,000 ETH ($37 billion, in current value) has been staked there. The plan is to merge it with the main Ethereum chain in the next few months. Supporters of Ethereum can also heave a sigh of relief as the move is expected to reduce the power demand of the network by as much as 99.5 percent.

No one knows exactly what the cryptocurrency platform’s big upgrade has in store for the industry. You might be tempted to think that cheaper execution will mean more work done and therefore a chain with a higher value and therefore a higher token price.

Ethereum Proof of Stake Mode

Since the launch, the platform has received periodic updates and a December 2020 update began the process of shifting the blockchain to the PoS system. Since the update, Ethereum has been running two parallel blockchains, one using Proof of Work called Mainnet while the other uses Proof of Stake called Beacon Chain. The initial white paper that described Ethereum also spoke of using a PoS system stake to validate the transactions on the blockchain. However, the platform was launched with the PoW system, with the plan to switch to PoS in the future. The blockchain is a public ledger of all transactions that occur on the network.

Historically, on proof-of-work, the target was to have a new block every ~13.3 seconds. Under proof-of-stake, slots occur precisely every 12 seconds, each of which is an opportunity for a validator to publish a block. Most slots have blocks, but not necessarily all (i.e. a validator is offline). In proof-of-stake, blocks are produced ~10% more frequently than on proof-of-work. This was a fairly insignificant change and is unlikely to be noticed by users. So, a blockchain is a digital ledger of distributed, decentralized, and often public transactions.

  • Ethereum’s blockchain coins like Big Eyes Coin, also use the same method and consume less energy.
  • Switching from proof-of-work to proof-of-stake will add a few complexities to the shard chains.
  • Proof of stake (PoS) lets a person validate block transactions according to how many coins they hold—the more coins owned, the more mining power they have.
  • This could be a point in favour of proof-of-work as it is harder to introduce bugs or unintended effects into simpler protocols accidentally.
  • In a blockchain where participants maintain a shared ledger, Bitcoin’s creator needed to find a way to keep people from trying to game the system and spend the same coins twice.
  • The Merge was when these two systems finally came together, and proof-of-work was permanently replaced by proof-of-stake.
  • Another innovation is that several, not one validator verifies the block before adding it to the system.

This because validators stand to lose their investment if they try to subvert the system, or fail to validate reliably and effectively.

How to Build a Successful Blockchain Product

An algorithm selects from a pool of validators based on the amount of funds they have locked up. In the month of September, the parallel Ethereum blockchains, Mainnet (Execution Layer), and Consensus Layer (Beacon Chain) are expected to merge such that the blockchain switches from the PoW to the PoS system. The Ethereum Foundation, however, states that the terminologies do not represent the planned roadmap, and Ethereum 2.0 sounds more like a new operating system, which it is not.

On the other hand, a single, isolated slashing event only burns a small portion of the validator’s stake. This midpoint penalty that scales with the number of slashed validators is called the “correlation penalty”. Node operators that wish to participate in validating blocks and identifying the head of the chain deposit ether into a smart contract on Ethereum. They are then paid in ether to run validator software that checks the validity of new blocks received over the peer-to-peer network and apply the fork-choice algorithm to identify the head of the chain. Nodes that propose blocks are only a small number of the total nodes on Ethereum.

In order to simplify and maximize focus on a successful transition to proof-of-stake, The Merge upgrade did not include certain anticipated features such as the ability to withdraw staked ETH. This functionality was enabled separately with the Shanghai/Capella upgrade. Gas fees are a product of network demand relative to the capacity of the network. The Merge deprecated the use of proof-of-work, transitioning to proof-of-stake for consensus, but did not significantly change any parameters that directly influence network capacity or throughput. Despite swapping out proof-of-work, the entire history of Ethereum since genesis remained intact and unaltered by the transition to proof-of-stake.
