It employs an algorithm that allows nodes in the network (computers running blockchain and storing all transaction records) to reach a consensus on the chronological order of events within a certain period. The consensus mechanism incentivizes nodes to propose blocks they genuinely believe will be accepted, in order to receive valuable rewards.  In consensus mechanisms such as proof of work (PoW) and proof of stake (PoS), nodes need to solve complex mathematical problems or hold a sufficient amount of tokens to achieve consensus. These consensus mechanisms aim to prevent malicious actors from cheating deliberately, such as double spending."}]}],"pr":"2253609dbbee76397fd39404f712da34cea3be3b585e00d363aa177d5ce09c64"}
