SYSTEM FOR ERRATUM DETERMINATION/RESULT SHARING ON BLOCK CHAIN

摘要

To provide a distributed ledger verification system.SOLUTION: A method for performing recording in a distributed ledger is to be executed by a first computer device, the method including: a step of generating a first hash value on the basis of a correct answer to a query from a first user; a step of generating first transaction data including the first hash value, the first transaction data associated with transaction data in the past; and a step of broadcasting the first transaction data. By being compared with second transaction data broadcast by a second computer device, the first transaction data is recorded in the distributed ledger. The second transaction data includes a second hash value generated on the basis of an answer to a query from a second user.SELECTED DRAWING: Figure 3
