Blockchain Fundamentals

Consensus Mechanism

A consensus mechanism is the protocol used by blockchain networks to agree on the validity of transactions and maintain a single source of truth. Popular mechanisms include Proof of Work (PoW), Proof of Stake (PoS), and Delegated Proof of Stake (DPoS). These systems prevent double-spending, ensure decentralization, and maintain security. Consensus mechanisms play a crucial role in enabling trustless environments where participants can transact without relying on a central authority, ensuring integrity across distributed ledgers.
