Abstract: 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.

Abstract: Disclosed herein are an apparatus and method for achieving distributed consensus based on decentralized Byzantine fault tolerance. The apparatus may include one or more processors and an execution memory for storing at least one program that is executed by the one or more processors, wherein the program is configured to receive delegate request messages, each including a first transaction for requesting distributed consensus proposed by a client, and determine congress candidate nodes forming a consensus quorum, to be consensus nodes based on the delegate request messages, generate a prepare message that includes a second transaction for obtaining consent to results of determination of the consensus nodes, and send the prepare message to the consensus nodes, and receive commit messages, each including an electronic signature of a corresponding consensus node, from the respective consensus nodes, and broadcast a reply message indicative of results of verification of the electronic signatures.

Abstract: Disclosed herein are a method for automatically allocating IP addresses for a distributed storage system in a large-scale torus network and an apparatus for the method. The method for automatically allocating IP addresses includes acquiring neighboring-node information from multiple storage nodes that constitute the system; generating torus network topology for the multiple storage nodes by combining the neighboring-node information; generating IP address information through which a position of each of the multiple storage nodes in a structure corresponding to the torus network topology can be identified; and allocating IP addresses to the multiple storage nodes by delivering the IP address information to the multiple storage nodes.

Abstract: 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.
