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.
