This is because blockchain is a chain-like data structure composed of data blocks connected in sequence according to time order, each block containing a certain amount of information. In a blockchain system, the generation and upgrading of new blocks need to meet certain conditions, such as reaching a certain consensus threshold. This process usually  takes some time for verification and confirmation.\n\nHowever, the upgrade of blockchain is not completely constrained by time. Due to the decentralized nature of blockchain, the upgrade process can be decided through consensus among the majority of nodes in the network. In some cases, developers may carry out upgrades as soon as possible to improve the performance and security of blockchain. But to ensure the stability and security of blockchain, it is necessary to carefully consider and plan upgrades."}]}],"pr":"1b77ad57cc27cc16edd4bf0c8be77dc2c4721826043dc42a36dd3d1c1d129d83"}
