The much anticipated Ethereum Merge is upon us - on September 15 UTC, Ethereum mainnet will be merging with the proof-of-stake consensus layer, the Beacon Chain.
The Beacon Chain was created on December 1, 2020, and has since existed as a separate blockchain to Mainnet, running in parallel.
This will be one of the most significant upgrades in Ethereum’s history, and took years of research and development.
