Distributed consensus algorithms are a class of algorithms that reach agreement between multiple nodes, mainly including pow, pos, and Byzantine fault tolerance. Taking pow as an example, nodes find blocks that meet specific conditions by continuously calculating hash values. When a node finds a block that meets the requirements, it broadcasts it to other nodes. After receiving the new block, other nodes verify it. If the verification passes, the new block is added to the local blockchain and the process of searching for the next block begins. Throughout this process, nodes sync new blocks according to pre-established consensus rules."}]}],"pr":"a612c3f658436971b79de45b4bf958ed0ba59a079fdccf80aa6ee2280a2c0717"}
