Abstract
A consensus is formed for a private database shared within a group. A block verification device includes: a private database shared within a group; a communication unit receiving a list of transactions from an overall leader device; a transaction processing unit executing the transactions identified based on the list and outputting the execution results; and a block processing unit generating a proposal including a list, a digest of the private database after execution of the transactions, and a private dataset included in the transactions. The communication unit transmits the proposal to another block verification device belonging to the same group, and transmits the list, the digest of the private database, and the digest of the private dataset to all the other block verification devices when it is determined that a consensus for the proposal is formed.
