There are two types of consensus mechanisms, namely Proof of Work (PoW) and Proof of Stake (PoS). In the PoW mechanism, miners compete in computational power to solve complex  mathematical problems proposed by the blockchain system. The miner who solves the problem first can obtain the block reward. In the PoS mechanism, nodes with more bitcoins are more likely to receive block rewards. Both consensus mechanisms ensure the decentralization and security of the blockchain while motivating miners to contribute to the blockchain network."}]}],"pr":"a12ea7582c29758c1d79aa1685e3025660b7422e28a58d243111422d619847ad"}
