The consensus mechanism solves the problem of how to achieve consistency in distributed scenarios for blockchains, laying the foundation for the security of the Bitcoin system. Common blockchain consensus mechanisms include Proof of Work (PoW), Proof of Stake (PoS), and  Byzantine Fault Tolerance (BFT). These consensus mechanisms solve the problem of mutual trust between nodes under the decentralized concept, allowing blockchains to operate securely and reliably in numerous situations."}]}],"pr":"070844de35dc6388544a31ec0664a6de4b3f3f5125c0e7fcaf267cb92681e751"}
