摘要： A metadata storage method, device, and a server are disclosed. The method includes: obtaining a metadata to be processed from the preset metadata storage system or from external of the preset metadata storage system; determining a type of metadata to be processed; processing the metadata to be processed to obtain a new metadata in a storage format corresponding to the type of metadata to be processed, wherein the storage formats correspond to different types of metadata to be processed and comprise at least one identical information kind for different types of metadata; and storing the new metadata in the preset metadata storage system. Thus a search for a metadata can be performed through a unified interface in a search engine, which is convenient to use.

摘要： Embodiments of the present disclosure disclose a method for processing privacy data of a block chain. When implemented by a block chain node, a specific implementation comprises: acquiring a data calculation transaction request initiated by a data user side based on a privacy smart contract; acquiring homomorphically encrypted source data according to the data calculation transaction request; invoking the privacy smart contract according to a calculation task in the data calculation transaction request; and performing an uplink operation on the data calculation transaction request and the calculation result to feed the data calculation transaction request and the calculation result back to the data user side of the data calculation transaction request, for the data user side to perform a homomorphic decryption and de-blinding on the calculation result, to acquire a plaintext calculation result. Thus, the scheme of processing the privacy data of the block chain is optimized.
