The invention discloses a big data transaction method, system, equipment and computer storage medium, wherein the method includes: a first data node publishes a tradable data index corresponding to its own tradable data set to a preset alliance chain sub-network, The alliance chain sub-network includes a preset number of alliance chain nodes; the second data node queries the tradable data index in the alliance chain sub-network, and judges whether the tradable data set meets its own needs according to the tradable data index. The chain node sends a payment reminder message, and sends a transaction request message to the first data node; the first consortium chain node receives the payment reminder message, and transfers the amount corresponding to the tradable data set from the wallet address of the second data node to the first data node. The wallet address of the data node; the first data node receives the request transaction message and provides the tradable data set to the second data node. The big data transaction method disclosed by the invention reduces the overhead of data nodes.
Description
technical field [0001] The present invention relates to the field of big data technology, and more specifically, to a big data transaction method, system, equipment and computer storage medium. Background technique [0002] With the development and maturity of big data technology, the application of big data has become more and more extensive, and big data transactions have also emerged as the times require. [0003] An existing big data transaction method is a big data transaction method based on blockchain and cryptography. The process is as follows: the first data node and the second data node generate transaction public-private key pairs on their own clients, and the data center provides each A single transaction public-private key pair is generated during the transaction process; the first data node publishes tradable data on the blockchain; the second data node submits a data transaction application to the blockchain, and generates an intermediate address based on the ...
