Blockchain-based data asset transaction method

Abstract

The invention discloses a blockchain-based data asset transaction method, which belongs to the technical field of blockchains, and comprises the following steps: a blockchain platform deploys a transaction smart contract, a user registers a contract transaction account through the blockchain platform, and the platform returns a pair of public key and private key of the user as an account address and a key for starting an account; the user compiles a transaction demand into a character string in the smart contract and publishes the character string in a blockchain transaction network, and matches an account meeting a transaction condition by using a blockchain consensus mechanism; a contract is triggered to automatically execute the transaction for the two parties meeting the transaction condition, wherein the transaction participants respectively sign by using respective private keys; and the transaction participants decrypt the signatures of the two transaction parties by using the public keys, broadcast the confirmed signatures through the block chain network and store the signatures into the block chain. The two transaction parties perform transaction through the smart contractin the blockchain, and the transaction information is encrypted, packaged and broadcasted to the blockchain by the private keys, so that the transaction information is not tampered, and the security is improved.

Description

technical field [0001] The invention belongs to the technical field of block chains, in particular to a data asset transaction method based on block chains. Background technique [0002] With the advancement of society and the rapid development of science and technology, the Internet has brought more convenience to people's lives. In people's lives, digital assets have been greatly developed. For example, in order to promote consumption, merchants issue vouchers to customers. With the development of the Internet, various electronic social media such as WeChat are becoming more and more popular, and electronic vouchers are becoming more and more popular. Electronic vouchers, online ticket purchases, etc. belong to digital assets. [0003] The existing digital asset transaction technology stores data information centrally in a central database, and the transaction process is completed by a "trusted" third-party organization, which is prone to unsafe events such as tampering w...

Problems solved by technology

[0004] The purpose of the present invention is to propose a blockchain-based data asset transaction method in order to solve the problem that a third-party organization needs to be used in the above-mentioned asset transaction process to cause information insecurity. To realize the transaction of data assets, there is no need to rely on a third-party organization, the information is more secure, and the matching efficiency of supply and demand during the transaction is high, and the advantages of effectively solving the problem of low efficiency of blockchain transactions
