Technical Field
The invention belongs to the technical field of computer internet application, and particularly relates to a block chain-based digital asset transaction method.
Background
Blockchains are a term of art in information technology. In essence, the system is a shared database, and the data or information stored in the shared database has the characteristics of 'unforgeability', 'whole-course trace', 'traceability', 'public transparency', 'collective maintenance', and the like. Based on the characteristics, the block chain technology lays a solid 'trust' foundation, creates a reliable 'cooperation' mechanism and has wide application prospect.
The existing digital asset transaction method has poor confidentiality effect on one-time transaction with long transaction time, transaction information of both parties is easy to be known by other people in transaction negotiation, and the confidentiality effect is poor.
Disclosure of Invention
The present invention is directed to a block chain-based digital asset transaction method, so as to solve the problems in the background art.
In order to achieve the purpose, the invention provides the following technical scheme: a blockchain-based digital asset transaction method, comprising the steps of:
s1, receiving a digital asset transaction request sent by a user side;
s2, generating a specific order information according to the request of the needed transaction, and generating a corresponding transaction block;
s3, sending order information to the transaction initiator;
s4, when a cochain request of a transaction node is received, generating three groups of information according to different corresponding transaction blocks, namely a group of public keys and two groups of keys, and respectively sending the public keys and the dynamic keys to a transaction initiator and a transaction receiver;
s5, two sets of exclusive passwords of the transaction block are set through the dynamic key, and after the passwords are set, the digital assets corresponding to the transaction party are extracted into the transaction block;
s6, verifying the asset issuer according to the account information through a public key;
s7, after the transaction information is determined, the corresponding exclusive passwords are respectively sent to the transaction initiator and the transaction receiver, and then the transaction is completed;
s8, when the transaction information changes, if the number of the digital money exceeds the number of the digital money in the block, the corresponding part is continuously extracted from the digital asset corresponding to the transaction party to the transaction block, the corresponding exclusive password is replaced after the extraction to complete the transaction, if the number of the digital money is less than the number of the digital money in the block, the transaction processing is normally carried out, and the redundant digital money is returned to the digital asset of the original transaction party after the transaction;
s9, if the transaction is cancelled, the digital assets return to the corresponding transaction party, and the transaction is ended;
and S10, after the transaction is finished, counting the transaction data, generating a single digital code, and recording the single digital code on the information of the corresponding transaction party.
Preferably, the transaction request in S1 includes information of the transaction initiator, the digital asset identification, the type and the number of the transaction product.
Preferably, the order information in S2 is a number.
Preferably, the digital number is composed of digital information of a transaction initiator, a digital asset identifier, a commodity quantity, digital information of a transaction receiver, a digital asset identifier and a transaction total amount.
Preferably, the account information is verified, that is, the set amount and type of the transaction item, information of both parties of the transaction, and the digital asset label are authenticated and backed up.
Preferably, the transaction block in S4 is divided into two parts, a public platform for negotiation and corresponding transaction information and a private platform for storing digital assets.
Preferably, the public platform can be opened to perform communication negotiation with the public key, and the private platform is opened with the public key and the two corresponding sets of exclusive passwords.
The invention has the technical effects and advantages that: according to the digital asset transaction method based on the block chain, the transaction block is formed by setting the transaction block, the transaction block is divided into a public platform used for negotiation and corresponding transaction information and a private platform used for storing digital assets, and the problem that the transaction secret is leaked in the transaction negotiation stage can be effectively avoided through the exclusive passwords formed by the group of public keys and the two groups of secret keys, so that the transaction information of both parties can be well protected, the transaction can be smoothly carried out, and the whole confidentiality of the transaction information is improved. The block chain-based digital asset transaction method is reasonable in design, can avoid transaction information leakage in the digital asset transaction process, ensures that transactions of both parties can be stably carried out, and is suitable for popularization and use.
