Abstract: A method for generating and managing a 3D coordinate system based on a transmission delay with an O(N) overhead by calculating a transmission delay between large-scale P2P nodes may comprise: generating a coordinate system and setting a node located at an origin of the coordinate system as a block generation node; calculating coordinates of a new node when an additional transmission delay occurs in a process of measuring a transmission delay from the block generation node to another node and requesting coordinates; performing self-cross check in which the block generation node periodically calculates coordinates thereof again; and updating coordinates of nodes comprising the origin of the coordinate system by reflecting a change in a transmission delay between nodes according to a network state change, based on a result of the self-cross check.
