$1.43T Sector. Market Cap. 69.90% Sector. Dominance. Consensus mechanisms (how networks come to agreement on transactions), such as Proof of Work (PoW) and Proof of Stake (PoS), are what make peer-to-peer digital transactions possible. While PoW and PoS are both used in crypto, they are quite different in how they work.
