Overview
Proposer-Builder Separation (PBS) and Proof of Stake (PoS) are two consensus algorithms used in blockchain networks, with PBS being a newer approach that separates the proposal and building of blocks, while PoS relies on validators 'staking' their own cryptocurrency to validate transactions, similar to how Ethereum's Vitalik Buterin and Bitcoin's Satoshi Nakamoto have discussed the importance of consensus algorithms in their respective whitepapers, and as seen in the implementation of PoS in Ethereum 2.0 and the use of PBS in the Solana blockchain, which has been praised by experts like Tim Berners-Lee and Joe Lubin for its potential to improve scalability and security
