Abstract: The present specification relates to a blockchain network system, and an operation method of a node accessing a blockchain network comprises: selecting a participant node, a congress node, a committee node, and a chair node on the basis of a random contention-free consensus to configure the role of each node; receiving, by the chair node, a delegation request from the congress node and using a transaction satisfying a consensus condition to instruct the committee node to perform block generation; approving, by the committee node, the block generation by communicating with the chair node; and disseminating, to the blockchain network, a new block generated as a result of the approval.

Abstract: The present specification relates to a blockchain network system. According to an operation method for a node accessing a blockchain network, each of a participant node, a congress node, a committee node and a chair node is selected to configure the roles of the nodes on the basis of random non-contentious consensus, the chair node receives a request for delegation by means of random non-contentious consensus from the congress node and instructs the committee node to generate a block, the committee node communicates with the chair node and approves block generation, and the participant node provides verification data according to the approval result, thereby generating a new block with which the verification data is combined.

Abstract: An operation method of a node device connected to a non-random consensus body proof-based blockchain network according an embodiment of the present disclosure comprises acquiring new block data propagated through the blockchain network; and performing a neural consensus body proof-based block generation process corresponding to the new block data according to a preset condition, wherein the neural consensus body proof-based block generation process includes extracting validity verification data from the new block data; acquiring neural consensus body designation information of a next block generated on the basis of a random consensus body proof process according to a verification process of the validity verification data; and generating validity verification data of the next block by selectively driving a consensus body node function unit on the basis of the neural consensus body designation information of the next block.

Abstract: An operation method of a device for constructing a neural block rapid-propagation protocol (NBRP)-based blockchain according to an embodiment of the present invention comprises: a routing acquisition step of obtaining routing information for one or more participant node terminals participating in a blockchain network; a topology configuration step of activating an NBRP as a scheme of data transmission or reception, and identifying a peer node terminal among the participant node terminals on the basis of the routing information; a communication mode determination step of determining a communication process by determining whether the NBRP is activated for the peer node terminal; and a data processing step of processing synchronization and session data communication for transaction data or block data with the peer node terminal according to the communication process.
