摘要： The provided are a method, terminal, and system for updating a digital currency wallet, and relates to the field of computer technology. A specific implementation of the method includes: sending, based on user trigger, a query request about whether the digital currency wallet needs to be updated to a trusted platform; receiving a query result returned by the trusted platform; in the case that the query result indicates that the digital currency wallet needs to be updated, withdrawing a digital currency from the digital currency wallet, synchronizing offline transaction data of the digital currency wallet, and sending an update request to the trusted platform; receiving a target update instruction sent by the trusted platform, wherein the target update instruction indicates account data corresponding to the digital currency wallet; and updating the digital currency wallet based on the account data indicated by the target update instruction. This implementation avoids losses of the digital currency during the update process, and the account data of the updated digital currency wallet remains unchanged, thereby improving user experience.

摘要： The present disclosure relates to a method, terminal and system for splitting, verifying and managing a digital currency in a transaction, mainly relating to the technical field of computers. A specific implementation of the method includes: determining a first transaction request indicating a digital currency and first transaction information; generating second transaction information including a second transaction amount according to the first transaction information; respectively signing the first transaction information and the second transaction information by using a private key of a first terminal; generating a first trust chain according to the signed first transaction information and the digital currency, and generating a second trust chain according to the signed second transaction information and the digital currency; and sending the first trust chain to a second terminal, so that the second terminal and the first terminal achieve, according to the first trust chain, an offline transaction corresponding to the first transaction amount included in the first transaction information. The implementation improves the security of the offline transaction while facilitating the use of the digital currency in performing the offline transaction.
