Abstract: Provided are a group service implementation method and device, an equipment and a storage medium. The specific solution is described below. A service transaction request is acquired. In response to the service transaction request including to-be-authenticated data and a threshold signature, a signature group corresponding to the threshold signature is determined. Group information of the signature group is acquired by querying a blockchain, where the signature group includes at least two members, the at least two members of the signature group are used for authenticating the to-be-authenticated data by adopting secure multi-party computation and generating the threshold signature for the to-be-authenticated data by adopting a signature private key, and the group information includes at least a verification public key of the threshold signature. The threshold signature is verified by adopting the verification public key in the group information.

Abstract: Provided are a blockchain-based data verification method and apparatus, a device, and a storage medium, relating to the field of computer technology, for example, a blockchain technology, and applicable to cloud computing and cloud services. The solution includes acquiring a data verification transaction request initiated by a data owner; generating a response signature value in the current verification round according to the data verification transaction request; and sending the response signature value to a blockchain network. The response signature value is configured to instruct the blockchain network to verify whether the to-be-verified data block is stored in a data storer.

Abstract: Provided are a blockchain-based data processing method and apparatus, a device, and a storage medium, which relate to the field of blockchain technology and can be used for cloud computing and cloud services. The specific implementation is: in response to a data usage request initiated by a data user, acquiring a signature result from an entrusted signer associated with to-be-used data after the entrusted signer audits the data user; calling a lease smart contract according to the data usage request to determine a signature verification key of the entrusted signer associated with the to-be-used data; performing verification on the signature result according to the signature verification key; and in a case where the verification passes, feeding back the to-be-used data to the data user. Therefore, the usage security of data can be improved.
