A data processing method, an apparatus, a device, and a medium in a blockchain fund settlement system are provided. A data processing method in a blockchain fund settlement system, performed by at least one processor of a settlement institution terminal, includes: querying, on a blockchain, a settlement request that is to be processed by the settlement institution terminal between a fund settlement initiator and a fund settlement recipient, the settlement request being generated by an initiator terminal of the fund settlement initiator and recorded on the blockchain; receiving the settlement request based on the querying; and generating a settlement result of a settlement performed according to the settlement request, and recording the settlement result on the blockchain.

Data processing method, apparatus, device, and medium in blockchain fund settlement system

A service processing method, apparatus, and storage medium of a blockchain system are provided. The service processing method includes obtaining authentication information of a service participant; determining whether data in the authentication information of the service participant is updated; generating, based on the data in the authentication information of the service participant being updated, a notification message according to the updated data; and transmitting the notification message to a service processing node subnetwork, the notification message instructing one or more service processing nodes in the service processing node subnetwork to process a service request according to updated authentication information of the service participant.

Service processing method and apparatus based on blockchain system, medium and electronic device

A data sharing method, server and storage medium including receiving a first part of a first key from a first client, the first key corresponding to encrypted data uploaded to a block of an information sharing system generating a first authorization code corresponding to the encrypted data; transmitting the first authorization code to the first client; based on receiving an access request from a second client for the encrypted data, obtaining a second authorization code and an incomplete key from the access request; based on the second authorization code being the same as the first authorization code and the second authorization code being valid, generating a second key according to the incomplete key and the first part of the first key corresponding to the encrypted data decrypting the encrypted data according to the second key to obtain the plaintext data; and transmitting, to the second client, the decrypted plaintext data.

Data sharing method, client, server, computing device, and storage medium

A signature generation method performed by an electronic apparatus is provided. A message abstract is generated according to a to-be-signed message and eigenvalues of a plurality of signature parties, an eigenvalue of a signature party being based on a random number of the signature party. Public keys and sub signatures of the plurality of signature parties are obtained, and a sub signature of the signature party is based on the random number of the signature party, the message abstract, and private keys of the plurality of signature parties. An aggregation public key is generated according to the public keys of the plurality of signature parties, and a length of the aggregation public key is less than a length of the plurality of public keys after splicing. An aggregation signature is generated according to a sum value of the plurality of sub signatures and the message abstract.
