METHOD FOR GENERATING NON-DETERMINISTIC DATA IN BLOCKCHAIN-BASED SYSTEM

Title:

METHOD FOR GENERATING NON-DETERMINISTIC DATA IN BLOCKCHAIN-BASED SYSTEM

Document Type and Number:

WIPO Patent Application WO/2019/190040

Kind Code:

A1

Abstract:

Provided is a method for generating non-deterministic data autonomously without using a separate external server in a blockchain-based system. A non-deterministic data generation method according to an embodiment of the present disclosure may comprise the steps in which: a first blockchain node among a plurality of blockchain nodes generates first non-deterministic data using a first smart contract shared on the blockchain, in response to a request for generation of non-deterministic data; the first blockchain node receives second non-deterministic data from a second blockchain node among the plurality of blockchain nodes; and the first blockchain node selects any one of the first non-deterministic data and the second non-deterministic data. At this time, the second non-deterministic data may be generated by the second blockchain node using the first smart contract shared on the blockchain.
