A new method has been proposed to solve the problem of information privacy in open blockchain systems using the zk-SNARK cryptographic zero-knowledge proof protocol. The proposed method has been implemented as a cryptographic scheme based on the libsnark library. To integrate the cryptographic scheme into the system, the Ethereum C++ client has been modified, where new functions and an interface for working with them in the form of precompiled contracts has been added.
Keywords: tenders, distributed systems, blockchain, zero-knowledge proof, zk-SNARK, Ethereum platform.
