  • Patent number: 11177939
    Abstract: A method may achieve an agreement among a plurality of nodes executed by one or a plurality of processors of a blockchain system including a distributed network of the plurality of nodes. The method may comprise: receiving a candidate block in a N-th round (N is a positive integer) by an arbitrary node among the plurality of nodes able to be promoted to producer nodes having a block generation status at a predetermined time for each round, determining whether the received candidate block is a valid candidate block, determining whether the valid candidate block is an unapproved block, and determining whether to vote for approval of the unapproved block by determining whether the unapproved block is a first received candidate block which is a first received candidate block within the N-th round by the arbitrary node.
    Type: Grant

  • Publication number: 20200090140
    Abstract: A crowdfunding method may be executed by one or more processors of a crowdfunding system based on a blockchain for creating a game operating on a distributed network composed of a plurality of nodes. The method comprises performing a crowdfunding service on the distributed network according to a configured smart contract. The smart contract comprises generating an initial block including data records related to game production plan information, sharing at least one transaction record related to electronic transactions of coins with the plurality of nodes, generating at least one new block including data records related to at least one transaction record, and updating a blockchain stored in at least one of the plurality of nodes so as to add the new block to the blockchain through communication with the distributed network.
