Description
Technical Field
The invention relates to the technical field of block chain data uplink, in particular to a block chain native implementation method of erc721 contract non-homogeneous asset standard.
Background
The current erc721 standard implementation is via an etherhouse contract, relying on a contract virtual machine. Leaving the ethernet environment cannot be performed, which limits the use of the erc721 standard in a blockchain system that is not an ethernet architecture. The use of the 721 standard in commercial scenarios is also limited due to inefficiencies in the ether house. The invention adopts a non-contract mode to realize erc721 standard, gets rid of the dependence of contract virtual machines and Ether houses, adopts a native block chain function mode to realize 721 standard functions of data uplink and data ownership transfer, and provides a block chain native realization method of erc721 contract non-homogeneous asset standard.
Disclosure of Invention
Aiming at the defects of the prior art, the invention provides a block chain native implementation method of erc721 contract non-homogenization asset standard, which gets rid of the dependence of a contract virtual machine and an Ethernet workshop, adopts a native block chain function mode to realize the advantages of data chaining, 721 standard functions of data ownership transfer and the like, and solves the problems that the implementation of the current erc721 standard is realized by the Ethernet workshop contract, depends on the contract virtual machine and cannot be executed when leaving the Ethernet workshop environment, so that the use of the erc721 standard in a block chain system of a non-Ethernet workshop framework is limited, and the use of the 721 standard in a commercial scene is also limited due to the low efficiency of the Ethernet workshop.
In order to achieve the purpose of getting rid of the dependence of contract virtual machines and Ether houses and achieving 721 standard functions of data chaining and data ownership transfer by adopting a native block chain function mode, the invention provides the following technical scheme: a erc721 contract non-homogeneous asset standard blockchain native implementation method, comprising a erc721token data structure containing token, memodata, issuer, and owner data fields.
Preferably, the token is a unique identifier of the uplink data.
Preferably, the medodata is summary information of uplink data.
Preferably, the issuers are token issuers, and the issuers are user addresses of the data uplink mechanisms in the corresponding commercial scenario on the block chain.
Preferably, the owner is a user address of a streaming object in the corresponding business scene on the blockchain.
Preferably, the users on the blockchain realize the circulation of a single 721tonken among the users of the blockchain through the tokenid.
Compared with the prior art, the invention provides a block chain native implementation method of erc721 contract non-homogeneous asset standard, which has the following beneficial effects:
the erc721 block chain native implementation method of the contract non-homogeneous asset standard comprises the steps of designing erc721 data structures, wherein the structures comprise token nids, unique identifiers of the token nids, issuers, addresses of the token nids issuing accounts, owner, addresses of current ownership accounts of the token nids, issuing organization accounts for calling 721token issuing modules, creating a new 721 data structure, filling the issuers with issuing account addresses, and owner for receiving the account addresses of the token nids, wherein the process is called 721token issuing, the account 721 with 721token circulation modules calls circulation modules and gives owned 721to objects to be circulated, the method is well applied to application of business data uplink and data copyright circulation, commercial expansibility is provided for a system, the use of the system meets control requirements better, meanwhile, a non-contract implementation erc721 standard is adopted, dependence of virtual machines and Ethernet workshops is eliminated, and a native chain function mode is adopted, the 721 standard function of data uplink and data ownership transfer is realized.
Drawings
FIG. 1 is a schematic view of the process of the present invention.
Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Referring to fig. 1, a block chain native implementation of erc721 contractual non-homogeneous asset criteria comprises a data structure erc721token, which contains token, memodata, issuer and owner data fields.
The block chain native implementation method of the erc721 contract non-homogeneous asset standard adopts a non-contract mode to implement the erc721 standard, gets rid of the dependence of a contract virtual machine and an Ethernet workshop, and adopts a native block chain functional mode to implement the 721 standard functions of data uplink and data ownership transfer.
tokenid is the unique identifier of the uplink data; the medodata is abstract information of uplink data; issuers are tokenid issuers, and issuers are user addresses of data uplink mechanisms in corresponding commercial scenes on the block chain; owner is the user address of the circulation object in the corresponding commercial scene on the block chain; the users on the blockchain realize the circulation of a single 721tonken among the users of the blockchain through the tokenid.
In operation, by designing erc721 data structure, the structure includes token, and the unique identifier of token, issuer, the address of the account issued by token, omnir, the address of the current ownership account of token, the issuing authority account invokes 721token issuing module, creates a new 721 data structure, fills out the address of the issuing account from issuer, fills out the address of the account accepted by omnir, this process is called 721token issuing, the account 721 with 721token invokes the circulation module, and circulates owned 721to the object to be circulated, at this time, owner of 721 becomes the object to be circulated.
In summary, token is a unique identifier of the uplink data, the id can be used to query the circulation history of the token, or the id can be used to query the original content of the uplink data in the file system; the subscriber is the token issuer and corresponds to the user address of the data uplink mechanism in the commercial scene on the block chain; the owner is the owner of the token at present and corresponds to the user address of the circulation object in the commercial scene on the block chain; the users on the blockchain realize the circulation of a single 721tonken among the users of the blockchain through the tokenid.
It is noted that, herein, relational terms such as first and second, and the like may be used solely to distinguish one entity or action from another entity or action without necessarily requiring or implying any actual such relationship or order between such entities or actions. Also, the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
