The Ethereum Proof-of-Stake Merge

As mentioned above, “The Merge” is a term, a crypto slang, if you will, that’s used to describe the transition of Ethereum from a proof-of-work consensus algorithm to one that uses proof-of-stake.

  • On 4th Nov 2020 the required specifications of ETH2 v1 and the Mainnet Deposit Contract Address for staking were released.
  • Moreover, as we stated previously, staking and running a validator requires effort, time and technical expertise.
  • Participants who violate the rules of the protocol are subject to forfeiture, in part or in full, of their staked assets.
  • He would later plead guilty to one count of conspiring to violate the International Emergency Economic Powers Act in 2021.
  • The total security of any given PoW public blockchain network is measured in hash power, or the total amount of computation devoted to securing the network.

The Ethereum Shanghai upgrade is designed to give ETH crypto token holders access to their staked assets, a major change for the network. The Ethereum Merge is a network update to transition Ethereum from proof of work to a proof-of-stake consensus mechanism. The switch moved the entire blockchain over to new PoS validator nodes that require staking or locking up 32 Ether to join.

How does proof-of-stake (PoS) differ from delegated-proof-of-stake (DPoS) used in other blockchain projects?

This means the network will process transactions at 64 times the transaction speed of the original single chain. Validators in Ethereum 2.0 are shuffled randomly and regularly between shards, a measure that is intended to reduce the potential for manipulation by bad actors. A vast amount of capital is being allocated toward researching and discovering how fixed block times will impact gas fees. We at Blocknative believe that we will see a new phenomenon, post-Merge, that will affect the entire network and the nature of the gas marketplace. The Execution Layer is responsible for state storage and management, state sync, virtual machine execution, transaction processing, mempools, etc.

This allows decentralized applications to “roll up” transactions into one off-chain for submission. The effect of this is that it reduces the data needed to execute a transaction. To ensure a smooth transition to proof-of-stake consensus, Ethereum core developers activated The Merge in a number of closed and public testnets. Since December 2021, Ethereum enthusiasts have emulated The Merge specifications in Kintsugi and Kiln purpose-made testnets. Technically, Ethereum started its journey to proof of stake in December 2020 with the launch of deposit contracts and the activation of the so-called Beacon Chain, a basic proof-of-stake coordination mechanism. In September 2022, its entire validation structure will migrate to proof of stake .

Alternatively, proof-of-stake guarantees the security of the network in a different way. In PoS, anyone with 32 ETH can deposit that ETH to become a validator, a node that participates in the network’s consensus algorithm. Finalizing a block requires 2/3 of all active validators to sign off on it. This makes attacks extremely expensive; it would be like a PoW system where if you use your mining hardware to attack the network then your hardware catches fire and is destroyed. The Merge made the Ethereum network substantially more energy efficient as it no longer required cryptocurrency miners that consumed a huge amount of electrical power. It is calculated that there is an incredible 99.988% reduction in the energy necessary to run the network, meaning that current Ethereum Staking Nodes are incredibly energy efficient.

A consensus mechanism is how a blockchain ensures that everybody involved in keeping records of transactions is being honest and not trying to claim that there is more in their – or other – accounts than there should be. Because Proof of Stake does away with hash-power driven mining, the need for large and capital-intensive mining farms is eliminated. In theory, this should lower the barrier to entry for validators, decreasing the risk of centralization.

How to set up an Ethereum Validator Node

The Merge was a change of consensus mechanism, not an expansion of network capacity, and was never intended to lower gas fees. If you’re operating a non-validating Ethereum node, the most significant change that came with The Merge was the requirement to run clients for BOTH the execution layer AND the consensus layer. Throughout Ethereum’s history, developers prepared for an eventual transition ethereum proof of stake model away from proof-of-work to proof-of-stake. On December 1, 2020, the Beacon Chain was created as a separate blockchain to Mainnet, running in parallel. The year 2022 has seen various upgrades, the most notable of which is the Ethereum Merge, which took place on September 15. In preparation for the integration, various modifications have occurred since the establishment of the Beacon chain.

Validators can also be slashed for being lazy and not participating in the network. Likewise, a validator could be slashed as a result of completely accidental actions including not having slashing protection up to date on failover servers or using duplicate keys. There is also the possibility for slashing to be triggered by massive Ethereum client software failure, which makes client diversity highly important. Validators that search for slashible events are called “whistleblowers” or “slashers.” When a whistleblower finds a slashable event, they will broadcast it to the network for the next block proposer to add the proof to their block. In turn, the block proposer will receive a reward for slashing the malicious validator.

What is the Ethereum Merge?

Undoing finalized transactions is economically inviable as it would require obtaining and burning over one-third of the total staked ETH. Thus, all stakeholders should be aware of these risks and take steps to mitigate the impact of any issues on their network usage, such as by halting or freezing deposits and withdrawals during key windows of possible disruption. In addition, validators, dapps, and service providers on Ethereum should prepare for the Merge by participating in forthcoming activations of the upgrade on the Sepolia and Goerli testnets. This will ensure node operators are up to date on best practices when following along with the Merge upgrade and bring to light any issues with the process before mainnet activation.

However, the impact this has on global energy consumption and climate change may be limited since the computers previously used for mining ether may be used to mine other cryptocurrencies that are energy-intensive. On 15 September 2022, Ethereum transitioned its consensus mechanism from proof-of-work to proof-of-stake in an upgrade process known as “the Merge”. In addition to the transition to Proof-of-Stake, The Merge included multiple upgrades to how the Ethereum network operates, as covered by this blog. Many of these upgrades make pre-chain data more important than ever when navigating a post-Merge world to ensure your users can transact with confidence. In addition to proposing blocks and submitting attestations, validators can also monitor each other for malicious behavior and “slash” other validators for failing to uphold the security of the network. Instead of settling all operations on one single blockchain, these shard chains spread operations across 64 new chains.

Since its inception, Ethereum has been secured with a PoW consensus mechanism, requiring hardware processing power to solve complicated math equations in a competitive process to mine the next block in the Ethereum blockchain. The Merge will change the overall consensus algorithm and will not expand the network capacity – this is why it won’t result in lower gas fees. However, there are scaling solutions in development that are designed to do just that, most of which are targeted at layer 2s. EIP 1559 will have been activated on Ethereum before the merge, and so by the time the merge happens the bulk of Ethereum transaction fees will already have been burned for months. The remaining fees that are not burned post-EIP-1559 (called “tips” or “priority fees”) will simply be paid to the block proposer of the proof-of-stake block instead of a proof-of-work miner. Ethereum in its current state is using proof-of-work to ensure consensus amongst the thousands of nodes in the network.

The Merge impacts all network participants. Are you prepared for the post-Merge future?

These rewards are credited to a non-staking account controlled by the validator , and are available immediately. These rewards are separate from protocol rewards for performing validator duties. As a result, a full Ethereum node now requires both an execution client and a consensus client.
