In a blockchain network, the consensus algorithm is a mechanism used to achieve verification, confirmation, and addition of transactions and blocks by network participants. Common consensus algorithms include Proof of Work (PoW), Proof of Stake (PoS), etc. The effective time of the upgrade proposal depends on the voting process in the consensus algorithm. For example, in the PoS consensus algorithm, the block producer decides the effective time of the upgrade proposal  based on the voting results. In addition, the effective time of blockchain upgrading is also affected by the number of network nodes, the block production speed, and other factors."}]}],"pr":"9929f4a508bd2b61820a246773532b492e5a9ff1aa539a3f80a515fe6f38de73"}
