Consensus mechanisms keep blockchains secure—ensuring all nodes agree on transactions without central control. Types: Proof of Work (PoW): Miners solve puzzles (Bitcoin). Proof of Stake (PoS): Validators stake tokens (Ethereum). Delegated PoS (DPoS): Elected validators confirm blocks (EOS, Tron). Proof of Authority (PoA): Trusted entities validate (VeChain, BNB Chain). They prevent fraud, ensuring trustless security!
