The Merge

Originally, "the Merge" referred to the most important event in the Ethereum protocol's history since its launch: the long-awaited and hard-earned transition from proof of work to proof of stake. Today, Ethereum has been a stably running proof of stake system for almost exactly two years, and this proof of stake has performed remarkably well in stability, performance and avoiding centralization risks. However, there still remain some important areas in which proof of stake needs to improve.
