Abstract
A non-transitory computer-readable recording medium stores a proof generation program that causes a computer to execute a process including: generating, for each process included in a supply chain, zero-knowledge proof that indicates validity of a cumulative value obtained by accumulating a value of each process from a most upstream process to the process and information regarding the cumulative value; and causing a blockchain to record the zero-knowledge proof and the information regarding the cumulative value.
Claims5
A non-transitory computer-readable recording medium storing a proof generation program that causes a computer to execute a process comprising:
- generating, for each process included in a supply chain, zero-knowledge proof that indicates validity of a cumulative value obtained by accumulating a value of each process from a most upstream process to the process and information regarding the cumulative value;
- and
- causing a blockchain to record the zero-knowledge proof and the information regarding the cumulative value.
A proof generation method that causes a computer to execute a process comprising:
- generating, for each process included in a supply chain, zero-knowledge proof that indicates validity of a cumulative value obtained by accumulating a value of each process from a most upstream process to the process and information regarding the cumulative value;
- and
- causing a blockchain to record the zero-knowledge proof and the information regarding the cumulative value.
An information processing apparatus comprising:
- a memory;
- and
- a processor coupled to the memory and configured to:
- generate, for each process included in a supply chain, zero-knowledge proof that indicates validity of a cumulative value obtained by accumulating a value of each process from a most upstream process to the process and information regarding the cumulative value;
- and
- record the zero-knowledge proof and the information regarding the cumulative value in a blockchain.
