Tag: consensus

Consensus mechanisms ensure agreement among participants in a blockchain network, validating transactions and securing the distributed ledger. Popular models include proof-of-work (PoW), proof-of-stake (PoS), delegated proof-of-stake (DPoS), and proof-of-authority (PoA). These mechanisms determine block validation, transaction finality, and network security. Innovations in sharded consensus, hybrid consensus models, and Byzantine Fault Tolerance (BFT) enhance blockchain scalability. The choice of consensus impacts transaction speed, energy efficiency, and network decentralization, influencing adoption by developers and investors alike.
