  • Publication number: 20200402026
    Abstract: When generating a block, a first blockchain management apparatus receives, from a prescribed information providing apparatus, a digest value generated from ledger information and a prescribed payment address, and the prescribed payment address, and generates a block. A second blockchain management apparatus verifies the block on the condition that the block that was received from the first blockchain management apparatus includes at least the digest value generated from the ledger information and the prescribed payment address, and a second transaction whereby consideration for providing the ledger information is paid to the prescribed payment address. In a case where verification of the block is successful, the second blockchain management apparatus forms a consensus with another blockchain management apparatus and adds the block for which consensus was formed to the ledger.
