Abstract
Implementations of the present disclosure include obtaining, by a client node of a blockchain network, a public key of a regulator node; generating, by the client node, one or more commitment values of a confidential transaction of the client node by applying a cryptographic commitment scheme to transaction data of the confidential transaction; generating, by the client node, encrypted regulatory information of the confidential transaction by encrypting the transaction data using the public key of the regulator node; and transmitting, by the client node to a consensus node of the blockchain network, a content of the confidential transaction for execution, wherein the content of the confidential transaction includes: the one or more commitment values; the encrypted regulatory information; and one or more zero-knowledge proofs of the transaction data.
