An explanation of the proof-of-stake consensus protocol and its role in Ethereum.

Proof-of-stake (PoS) Copy .md Copy .md Edit page (opens in a new tab) On this page Proof-of-stake (PoS) underlies Ethereum's consensus mechanism . Ethereum switched on its proof-of-stake mechanism in 2022 because it is more secure, less energy-intensive, and better for implementing new scaling solutions compared to the previous proof-of-work architecture. Prerequisites To better understand this page, we recommend you first read up on consensus mechanisms . What is proof-of-stake (PoS)? Proof-of-stake is a way to prove that validators have put something of value into the network that can be des
