Embodiment Construction

[0074] The specific implementation of a method and device for processing non-homogeneous tokens based on blockchain provided by the embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that the described embodiments are only some of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0075] (1) Before introducing the processing method of non-homogeneous certificates based on blockchain, the issuance process of non-homogeneous certificates will be explained first.

[0076] ERC-721 is a standard for non-homogeneous tokens, which manages non-interchangeable assets and maps assets in the physical world to the blockchain. ERC-721 defines the minimum interface that the s...

Abstract

The invention discloses a block chain-based non-homogenized token processing method and device, which can effectively realize distribution and decentration by using a block chain technology, so that data has the advantages of non-tampering, whole-course trace leaving, traceability, collective maintenance, publicity, transparency and the like. Double transaction locks are used and are respectively controlled by the user and the issuer, so that mutual restriction of the user and the issuer is ensured, and the situation that one party disables is avoided; that is, it is ensured that the issuer cannot tamper the virtual commodity, the virtual assets of the user are protected, the uniqueness and non-tampering performance of the user are ensured, and the behavior of Japanese pulling is effectively eradicated.

Description

technical field [0001] The invention relates to the technical field of block chains, in particular to a method and device for processing non-homogeneous certificates based on block chains. Background technique [0002] Blockchain is a new application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm. Blockchain (that is, Blockchain) was born in the subprime mortgage crisis in 2008, and was first applied to the risk control of Bitcoin. It is essentially a decentralized database. At the same time, as the underlying technology of Bitcoin, it is a series of passwords Each data block contains a batch of bitcoin network transaction information, which is used to verify the validity of the information (ie anti-counterfeiting) and generate the next block. The blockchain is designed to maintain data integrity, shared by all participants, permanently recorded in chronological order, and a distrib...
