What was The Ethereum Merge?

 

What was The Ethereum Merge? The Merge was the joining of the original execution layer of Ethereum (the Mainnet that has existed since genesis) with its new proof-of-stake consensus layer, the Beacon Chain. It eliminated the need for energy-intensive mining and instead enabled the network to be secured using staked ETH. It was a truly exciting step in realizing the Ethereum vision—more scalability, security, and sustainability.

Initially, the Beacon Chain shipped separately from Mainnet.Ethereum Mainnet - with all its accounts, balances, smart contracts, and blockchain state - continued to be secured by proof-of-work, even while the Beacon Chain ran in parallel using proof-of-stake. The Merge was when these two systems finally came together, and proof-of-work was permanently replaced by proof-of-stake.

 

Imagine Ethereum is a spaceship that launched before it was quite ready for an interstellar voyage. With the Beacon Chain, the community built a new engine and a hardened hull. After significant testing, it became time to hot-swap the new engine for the old one mid-flight. This merged the new, more efficient engine into the existing ship enabling it to put in some serious lightyears and take on the universe.
