Each user has a ledger recording their account balance and other relevant transaction information. When a transaction occurs, the information is recorded on all users' ledgers. This decentralized storage method ensures data security and transparency, as altering one's own ledger by a single user will not affect the data in  the hands of others. The maintenance of data is achieved collectively by all users."}]}],"pr":"d16addd3897c88b42ec670a4ba2c978d822f3ef3e28554de4c45e1b533b9db67"}
