Abstract

Abstract:

The big data oriented blockchain for trade clearing was introduced,including consensus,secure transmission of trading data storage,data search,encryption and decryption of trading data and trade clearing business.The analysis of the framework design on dismantlement and combination of the composite trading was emphasized,and the potential value and significant meaning of blockchain data on risk decision and assessment through the big data analysis were identified.

Key words: big data, blockchain, consensus mechanism, cryptography, clearing system
