The consensus mechanism is an algorithm used in blockchain systems to determine who  has the right to record transactions and receive system rewards. There are two commonly used consensus mechanisms: Proof of Work (PoW) and Proof of Stake (PoS).\n\nIn the PoW mechanism, miners need to compete with each other in terms of computer computing power to solve the complex computational tasks thrown by the blockchain system. Whoever solves it first will have the right to record transactions and thereby receive block rewards. Bitcoin is a representative example of using the PoW consensus mechanism. Miners successfully mine a block every time they complete the complex computational task."}]}],"pr":"e17c1e73bdd35c4f5489d452133bfec56e2685c09b82b9b78fa0d6ca6ff48855"}
