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.

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.

The present invention provides a novel use of coccidian, specifically relates to the use of coccidian as a vaccine live vector. The present invention further provides a live vaccine with coccidian as a vector, which is transgenic coccidian capable of expressing exogenous protein or stably transfected coccidian that contain expression vector and can express exogenous coccidian. The present coccidian vector live vaccine can induce organisms to simultaneously generate protective humoral and cellular immune responses (including the mucosal immune response), as well as generate memory responses, which can be readily carried out and has stable effect and high biological safety without generating immune tolerance.

Use of coccidian
