A method for selecting a consensus node in an apparatus for generating a blockchain includes reading a nonce from the nonce chain of a node, performing an operation on the read nonce and previous height information, and comparing the result of the operation with a reference value in order to select the node as a consensus node.

Method and apparatus for selecting distributed consensus node based on proof of nonce

Disclosed herein are an apparatus and method for apparatus for synchronizing consensus node information in a blockchain network. The apparatus for synchronizing consensus node information includes one or more processors, and execution memory for storing at least one program that is executed by the one or more processors, wherein the at least one program is configured to receive a committed message for block consensus from the blockchain network and verify nodes participating in the block consensus, set a block number required to participate in the block consensus to a block size of a start block of a section corresponding to the block consensus, and broadcast consensus node information including the block number to the blockchain network.

Apparatus and method for synchronizing consensus node information in blockchain network

Disclosed herein is a method for generating a blockchain, which includes selecting, by a first master node that generated a first block, second candidate nodes from a node pool according to a consensus node selection scheme using a nonce, and selecting, by the first master node, a second master node using the result of a vote taken by first candidate nodes. Here, among candidate blocks generated by the second candidate nodes, the candidate block generated by the second master node is locked as a second block.
