Abstract: Disclosed herein is a method for adding an additional chain to a blockchain. The method includes depositing, by a node of the blockchain, an asset corresponding to the additional chain; selecting the node as one of consensus nodes for connecting an additional block to the additional chain based on a share value corresponding to the asset; and performing, by the node, distributed consensus for connecting the additional block. Here, nodes constituting the blockchain include major shareholder nodes for processing transactions.

Abstract: Disclosed herein is a method for a distributed consensus. The method includes generating public vote identifiers using public node identifiers corresponding to nodes constituting a blockchain, generating a pass vote list by performing an operation corresponding to a success probability (p) for each of the public vote identifiers, and performing a distributed consensus based on at least part of consensus congress nodes corresponding to the pass vote list.

Abstract: Disclosed are an apparatus and method for electing a committee node in a blockchain. The apparatus for electing a committee node in a blockchain is configured to transmit a staking transaction including validator information to a blockchain system to register a validator node, generate a draw pool for electing a committee node based on the validator information, change entries of the draw pool using a predefined shuffling algorithm, select a preset number of top entries as votes of a committee member from among the entries of the shuffled draw pool, and elect, as the committee node, the validator node that has acquired votes of a committee.

Abstract: Disclosed herein is an apparatus and method for synchronizing a block in a blockchain network. The apparatus synchronizes node information of existing participating nodes connected to a blockchain network by joining the blockchain network, determines synchronization target blocks by calculating the current section of a blockchain using an agreed-upon block received from the existing participating nodes, receives a block header of each section and the segment hash table of a snapshot that are verification data for verifying synchronization target data for the synchronization target blocks from participating nodes that are not connected as peers, among the existing participating nodes, generates a snapshot by receiving snapshot segments and the blocks of the current section, which are the synchronization target data, from participating nodes connected as peers, among the existing participating nodes, verifies the snapshot generated from the snapshot segments, and synchronizes the verified snapshot.
