Problems solved by technology

Big data has entered the offline link from online, and the value of data has been recognized by the industry, followed by the transaction and circulation of big data. However, the traditional centralized transaction method cannot meet the growing demand. In this case , how to effectively use blockchain technology to realize big data transactions has become an urgent problem to be solved

Embodiment 1

[0033] like figure 1 As shown in , in this embodiment there is a data transaction consensus network and a regulatory consensus network, and all nodes jointly maintain a ledger record through the blockchain. Any node can publish a transaction, and the data transaction is published to the blockchain in the form of a smart contract, and distributed to each node through the P2P network, and a consensus is finally reached, and the transaction can also be published to the supervisory consensus network to reach a consensus. In addition, smart contracts are automatically executed through the verification nodes of the consensus network. in,

[0034] The buyer's node publishes a data transaction smart contract through the P2P network, and each node participating in the blockchain reaches a consensus; the seller's node provides encrypted transaction data and conducts smart contract negotiation; the data transaction consensus network is a P2P network, which is completed through the block...

Abstract

The invention relates to the technical field of big data, block chains and smart contracts, and in particular to a block chain smart contract-based data transaction method. According to the block chain smart contract-based data transaction method, purchase and sale behaviors of purchasers and sellers of transactions are recorded through block chains, automatic execution of the transactions is realized by utilizing smart contracts, and big data for the transactions is not recorded in the block chains and is encrypted and stored in an external data memory, so that the purchasers only can obtain the data after the smart contracts are successfully transacted; and moreover, the purchasers can publish transactions through a supervisory block chain consensus network, so that third-party witness is realized and the security guarantee of data transactions is increased.

Description

technical field [0001] The invention relates to the technical fields of big data, block chain and smart contract, in particular to a data transaction method based on block chain smart contract. Background technique [0002] Blockchain technology, also known as "distributed ledger technology", is a technical solution for decentralization and collective maintenance of distributed ledgers. Its essence is a distributed database system that is collectively participated by multiple nodes. Blockchain is not a single technology, but the result of the integration of multiple technologies. Using blockchain technology to maintain a reliable and difficult-to-tamper ledger record can reduce the risk of trust and effectively reduce the collaboration among participants. maintenance costs. [0003] With the development of blockchain technology, smart contracts become possible, and this disruptive technology will bring about major changes in the structure of human society. Smart contract...
