What Is Proof of Stake (PoS) in Blockchain?

Proof of Stake (PoS) is a consensus mechanism used in blockchains to process transactions and create new blocks. In Solana, it serves as the protocol for selecting validators for each Epoch.

Staking participants lock their tokens and get a chance to be selected as a validator, along with the standard staking benefits.

After the Ethereum Merge, staking became an energy-efficient, viable alternative to PoW (Proof of Work). It also reinforces the decentralization principles that Web3 is built on.
