However, in practical applications, blockchain systems can  define multiple states based on different business scenarios and requirements. These states are usually related to the data and transactions in the blockchain, such as pending transactions, confirmed transactions, and unreviewed transactions. In addition, blockchain can also define states based on the status of nodes and the network, such as online status, offline status, synchronization status, etc. Overall, the types of states defined in the blockchain are not fixed, but are flexibly set according to actual application scenarios and requirements."}]}],"pr":"27926548d0a4c8e6ac2506bd73c50276e09ca7f40ea513372b1e8664e7f947e5"}
