Title:
METHOD FOR ENABLING ACCESS TO PAST TRANSACTION IN BLOCKCHAIN NETWORK, AND NODE
Document Type and Number:
WIPO Patent Application WO/2019/117311
Kind Code:
A1
Abstract:
Provided is a method for efficiently enabling access to a past transaction in a blockchain network. A first node 101 generates a new block from one or more transactions accumulated by using, as a memory pool, a storage device or a storage medium accessible from a storage unit 101C or the first node 101 (S201). If selection of the generated block was agreed upon in a blockchain network (100), the generated block is added to the blockchain, at each node (S202). In an embodiment of the present invention, various agreement algorithms can be used, but an agreement algorithm with finality is required. Each node generates and stores an identifier for uniquely identifying each transaction on the basis of the height of the added block and the order within said block (S203).
