Proof-of-stake (PoS) is the consensus mechanism that Ethereum will use after The Merge. Ethereum is moving off of proof-of-work (PoW) to proof-of-stake because it is more secure, less energy-intensive, and better for implementing new scaling solutions. While it has always been the plan to transition to proof-of-stake, it is also more complex than proof-of-work, and refining the mechanism has taken years of research and development. The challenge now is to implement proof-of-stake on Ethereum ...
