Consensus Mechanisms Explained
Consensus mechanisms are the rules that allow blockchain networks to agree on which transactions are valid without needing a central authority. Learn about Proof of Work (used by Bitcoin), Proof of Stake (used by Ethereum), and other methods that keep crypto networks secure and decentralized. Essential knowledge for understanding how cryptocurrencies actually work.
