Title:
BLOCKCHAIN MANAGEMENT SYSTEM, BLOCKCHAIN MANAGEMENT DEVICE, INFORMATION PROVISION DEVICE, AND BLOCKCHAIN MANAGEMENT METHOD
Document Type and Number:
WIPO Patent Application WO/2019/167116
Kind Code:
A1
Abstract:
The present invention reduces storage costs of an entire network while suppressing the possibility of ledger data loss of a blockchain. At the time of block creation, a first blockchain management device receives, from a prescribed information provision device, a summary value generated from ledger information and a prescribed payment address, and the prescribed payment address, and generates a block. A second blockchain management device verifies the block on the condition that the block received from the first blockchain management device includes at least the summary value generated from the ledger information and the prescribed payment address, and a second transaction whereby consideration for the provision of the ledger information will be paid to the prescribed payment address. If verification of the block is successful, the second block chain management device forms an agreement with another blockchain management device and adds to the ledger the block for which the agreement was formed.
