Abstract: Provided is a system and method for estimating an end-to-end delay between blockchain nodes in peer-to-peer (P2P) networks. The system includes a coordinate system construction unit configured to designate an origin node and anchor nodes among participating nodes having a distributed ledger of P2P networks, construct a first coordinate system of a predetermined dimension by exchanging control messages between the origin node and the anchor nodes and the participating nodes, and construct a second coordinate system of another predetermined dimension and a dimension determination unit configured to determine a dimension to be applied to the current P2P networks by comparing dimension-specific delays or control message overheads of the first coordinate system and the second coordinate system.
