BLOCK CHAIN-BASED DATA MANAGEMENT METHOD, BLOCK CHAIN SYSTEM, SERVER AND READABLE STORAGE MEDIUM

摘要

Disclosed are a block chain-based data management method, a block chain system, a data hosting server and a readable storage medium, the method comprising: a requesting-side node broadcasting via a block chain network a data transaction request directed to a request-receiving-side node, wherein the data transaction request comprises transaction attribute data; the request-receiving-side node acquiring the data transaction request via the block chain network, and sending to the block chain network, and according to the transaction attribute data of the data transaction request, a transaction response request corresponding to the data transaction request, wherein the transaction response request comprises response attribute data and the response attribute data comprises a data identifier; and after the requesting-side node acquires the response attribute data of the transaction response request via the block chain network, determining the data identifier in the response attribute data, and downloading data corresponding to the data identifier from a preset data hosting server according to the determined data identifier. The present invention can be used to improve security of data transactions and storage.
