Quorum protocols

Quorum protocols are methods used in distributed systems, like cryptocurrencies or data networks, to ensure all participants agree on the same data or transaction. They require a majority or a specific subset of participants to confirm an action, preventing fraud or errors. Think of it as a committee voting: only when enough members approve does a decision become official. This approach maintains integrity, consistency, and security, especially when participants are spread across different locations or devices, ensuring the system functions reliably without a central authority.
