An amalgamation of Beacon Chain with original Ethereum PoW
The Beacon Chain, which shipped on December 1, 2020, is the Ethereum network’s upgrade to a Proof-of-Stake blockchain. Essentially it is a PoS consensus layer that handles a network of stakers. In order to understand what the Beacon Chain can do for the network, it’s important to understand the problems that the network currently faces. Right now, Ethereum’s consensus layer is what’s known as a Proof-of-Work consensus layer, same as Bitcoin’s.
