Abstract: An information synchronization method includes determining, by a first node with an information synchronization capability based on a first node information list and a second node information list, a second node on which an information synchronization is not performed and that is in a node group to which the first node belongs, where the first node information list includes first node information of third nodes in the node group, and the second node information list includes second node information of a fourth node that is in the node group and on which information synchronization has been performed, selecting, by the first node, the second node, performing the information synchronization on the second node, and adding third node information corresponding to the second node to the second node information list.

Abstract: A transaction verification method is applied to an electronic device that includes a secure element (SE), a trusted execution environment (TEE), and a rich execution environment (REE), and includes, in a transaction verification process, execution of service logic and data storage are performed on a TEE side instead of on an SE side, and transaction validity verification is reserved on the SE side.
