HotStuff

HotStuff is a protocol for coordinating a group of computers (called nodes) to agree on consistent data, like transactions in a blockchain. It ensures all nodes reach consensus even if some are slow or malicious, by using a process where they propose, vote, and confirm decisions in multiple rounds. HotStuff is designed to be efficient, scalable, and secure, enabling rapid and reliable agreement across distributed systems. Think of it as a well-organized meeting where all participants agree on a final decision, even if some voices are noisy or uncooperative.
