blockchain protocols

Blockchain protocols are sets of rules that govern how data is recorded, stored, and shared on a blockchain network. They ensure that all transactions are secure, transparent, and immutable, meaning they cannot be altered once confirmed. Each participant in the network verifies transactions according to these protocols, which helps maintain trust and accountability. Common examples include Bitcoin’s protocol for cryptocurrency transactions and Ethereum’s for smart contracts. Essentially, blockchain protocols create a digital ledger that everyone can trust, without the need for a central authority.
