Lesson Overview

1.10 – Why Consensus Is Vital to Blockchain: Consensus is the process by which all nodes in a blockchain agree on which transactions are valid. Without it, the network would fall into confusion or manipulation. Consensus replaces traditional management with mathematics and shared rules. Methods like Proof of Work and Proof of Stake ensure honesty through cost, effort, or collateral. When everyone follows the same protocol, data becomes universally accepted and permanent. Consensus transforms strangers into collaborators, allowing trust to exist without central authority. It is the heartbeat that keeps every decentralized ledger synchronized and credible.
