Here's What You Need To Know

Ethereum’s long-awaited transition from proof-of-work (PoW) to proof-of-stake (PoS) is upon us as the Merge looms in less than 10 hours. There’s plenty to consider for the wider cryptocurrency space — and here’s what you need to know.

What is the Merge?

The Ethereum blockchain will transition away from its energy-intensive consensus mechanism PoW as its execution layer merges with the new PoS consensus layer known as the Beacon Chain.

The Beacon Chain went live in December 2020, allowing ecosystem participants to deposit or ‘stake’ ETH to become the new validators of the network, in doing so replacing PoW miners that had previously put in the work to process transactions, produce blocks and secure the network.

In its simplest form, the Merge will make the Ethereum network use 99% less energy and provide greater scalability, security and sustainability.

Ethereum’s mainnet (PoW) and the Beacon Chain (PoS) have been running concurrently and will finally merge, hence the name, ushering in a new era for the smart contract blockchain network. The entire transaction history of Ethereum will be carried across as the new consensus mechanism takes control of the network.

Who maintains the network after the Merge?

As explained, users that are able to stake a total of 32 ETH are eligible to become individual validators of the Ethereum Beacon Chain. Validators are assigned to produce blocks at random and validate transactions and blocks created by other validators in the network.

Users can also take part in pooled or centralized staking pools by staking smaller amounts of ETH, which promises a share of rewards for validating and maintaining the network. There are multiple staking options to consider for those interested in playing a part in the network’s new consensus mechanism.

A recent report from blockchain analytics platform Nansen shows that just over 11% of the total circulating ETH is staked, with 65% liquid and 35% illiquid. There are a total of 426,000 validators and some 80,000 depositors, while a small group of entities commands a significant portion of staked ETH.

Three major cryptocurrency exchanges account for nearly 30% of staked ETH, namely Coinbase, Kraken and Binance. Lido DAO, the biggest Merge staking provider, accounts for the largest amount of staked ETH with a 31% share, while a fifth unlabelled group of validators holds 23% of staked ETH.
