Distributed ledger technology is a decentralized database that stores data across multiple nodes, which collectively maintain the same ledger. In the banking module, whenever a transaction occurs, it is packaged into a block and added to the blockchain. This enables the banking module to monitor balance changes in real-time and provide users with real-time balance query functionality. Furthermore, due to the transparency and immutability of blockchain, the banking  module can ensure the security and accuracy of account balances."}]}],"pr":"e9e9ddca14a8b8e76c3d5380ecb5408620257c82ff6b672768a8e78c12d080a9"}
