As shown in fig. 1, an embodiment of the present application provides a digital asset management method applied to a heterogeneous certification NFT engine entity, including, but not limited to, the following steps:
step 11: an NFT creation request for digital content is obtained from a user portal, the NFT creation request carrying a digital fingerprint ID of the digital content.
Wherein the digital fingerprint ID is a unique identifier of the digital content, the digital content corresponding to the digital fingerprint ID is stored in a de-centralized storage engine entity, the digital content comprises an entity asset or a virtual asset, for example, the digital content may include, but is not limited to: pictures, videos, virtual goods, 3D assets, games, coupons, music files, artwork, tickets, etc., in embodiments of the present application, both physical and virtual assets may be NFT-ized.
Since there is a risk of losing content resources and being tampered with when digital content is stored in the centralized system, and if digital content is stored in the blockchain, the storage cost is too high, so in the embodiment of the application, the digital content is not stored on the blockchain, but is stored by the decentralizing storage engine entity, so that the storage cost is reduced on the premise of ensuring that the content is not lost and tampered with. Among other things, the decentralised storage engine entities include, but are not limited to: an interstellar File System (Inter Planetary File System, IPFS) or a MEMO File System (MEFS) based on the MEMO distributed cloud storage protocol, etc.
Optionally, the NFT creation request carries at least one of the following creation parameters: asset class (category), license name (token_name), maximum supply (max_supply), issuer (issuer), information indicating whether to be homogenous (funnelable), information indicating whether to be transferable (transferable), information indicating whether to be vendable (sellable), sales commission (rev_split), and base universal resource identification (base Uniform Resource Identifier, base_uri).
Step 12: in response to the NFT creation request, invoking an NFT smart contract based on a dgoods protocol from a EOS (Enterprise Operation System) blockchain network and creating an NFT of the digital content based on the NFT smart contract.
Step 13: an EOS multi-index table is generated based on the creation parameters of the NFT and the digital fingerprint ID.
The EOS multi-index table includes a digital asset ID corresponding to the digital fingerprint ID.
Optionally, after step 11, the method may further include: uploading the digital content to an off-centered storage engine entity, and receiving a digital fingerprint ID of the digital content returned by the off-centered storage engine entity, wherein the digital fingerprint ID is a unique identifier of the digital content. The scheme can be understood as a unified implementation of the digital asset creation process and the creation process of digital content.
Wherein, after the data is stored by the decentralised storage engine entity by using the API interface, the fingerprint ID of the digital content is obtained, and the fingerprint ID is a unique identifier for describing the piece of digital content, and the specific form of the fingerprint ID can be a unique hash value.
Where dGoods is an open source and free digital asset standard with metadata templates for 3d and 2d assets, such as games, coupons, music files, artwork, tickets, and the like. The construction concept of the standard is as follows: the digital asset requires the same authenticity credentials as the physical real world object, in particular, a metadata template (e.g., EOS multi-index table) may be specified depending on the type of digital good used. dGoods may represent attributes describing an authenticity certificate by an immutable field, such as a digital fingerprint ID.
It is noted that the step of the NFT engine entity invoking the NFT smart contract may occur after step 11 or after the step of uploading the digital content. The step of the NFT engine entity scheduling NFT smart contracts occurs before the EOS multi-index table (dgoodstats) is generated.
Optionally, generating the EOS multi-index table based on the creation parameters of the NFT and the digital fingerprint ID includes: if the EOS multi-index table of the digital content does not exist in the EOS blockchain network, generating the EOS multi-index table by all creation parameters and the digital fingerprint ID of the NFT; if the EOS multi-index table of the digital content exists in the EOS blockchain network, the NFT creation parameters and the digital fingerprint ID which do not exist in the existing EOS multi-index table are written into the existing EOS multi-index table. The EOS index table comprises a digital asset ID (dgoods_id) and a universal resource identifier token_uri, wherein the token_uri consists of a base_uri and a related universal resource identifier relative_uri, and the relative_uri is used for storing the digital fingerprint ID. In addition, because the dGoods standard supports "multiple sort tokens" in a contract, digital asset IDs can be implemented as an array type, enabling batch creation (or casting) NFTs and batch transfer (or transferring) NFTs, which can reduce transaction complexity and cost. In addition, the digital assets are stored in the multi-retrieval memory table of the EOS, so that retrieval and inquiry are facilitated. In addition, the EOS index table may further include other parameter information of the NFT, such as asset class (category), license name (token_name), maximum supply (max_supply), issuer (issuer), information indicating whether homogenization (function), information indicating whether transfer is possible, information indicating whether sell (sell) is possible, sales commission (rev_split), etc., in addition to the digital asset ID and token_uri.
And uploading the EOS multi-index table corresponding to the digital content to an EOS blockchain network for storage, so that the information quantity stored on the blockchain can be reduced, and the method has remarkable effect on reducing the cost.
Optionally, the NFT creation request carries at least one of the following creation parameters: asset class, certification name, maximum supply, issuer, information indicating whether it is homogenous, information indicating whether it is transferable, information indicating whether it is vendable, sales commission and base universal resource identification base _ uri.
Optionally, the EOS index table includes a digital asset ID and a universal resource identifier token_uri, where the token_uri is composed of a base_uri and a related universal resource identifier related_uri, and the related_uri is used to store the digital fingerprint ID.
The NFT engine entity of the embodiment of the application acquires an NFT creation request aiming at digital content from a user portal, responds to the NFT creation request, calls an NFT intelligent contract based on a dgoods protocol from an EOS blockchain network, and generates an EOS multi-index table based on at least part of creation parameters carried by the NFT creation request and the digital fingerprint ID. Therefore, NFT intelligent contracts are realized based on dgoods protocol, EOS blockchain network is used at the bottom layer, network transaction speed and throughput can be greatly improved, high-frequency transaction can be carried, no creation (or casting) or transaction cost is needed, transaction cost is reduced, and user experience is improved.
Steps 11 to 13 above are the NFT creation process (casting process), specifically, after receiving the NFT creation request of the digital content, calling the NFT smart contract, such as the create function of migu. When an NFT is instantiated by the contract, the following parameters need to be entered: the properties of asset category, asset name token_name, maximum supply max_supply, issuer, whether homogenous funiculble, transferable, sell, commission rev_split, and base_uri. Then judging whether the imported category and the token_name exist or not, if not, creating the category and the token_name, and writing the imported parameter information into an EOS multi-index table dGoodstats, wherein the token_name is used as a unique main key, and the category is used as a scope (scope). The convenience of token search and filtering can be realized through the name hierarchy naming structures of the category and token_name. Wherein the migu. Token contract can support the casting of both NFT and NF.
Taking digital content as an example of tickets, embodiments of the present application can create a concert ticket with a ticket name migu. Ticket with a maximum supply of 1000, each ticket being designated as non-replaceable because each ticket has its own designated seat, while each ticket can also be designated as being transferable or saleable, wherein the benefit of the sale is 5% of the sales amount and the seller obtains an additional 95%, thus creating a ticket type NFT.
In addition, it should be noted that, in addition to the implementation of the above-described unified flow for digital asset creation and digital content creation, the embodiments of the present application may also correspond to independent flows for both processes. Specifically, the method comprises the following steps: the user portal obtains the digital content creation request and sends the digital content creation request to the digital content authoring engine entity for digital content authoring. After the creation is completed, the user portal uploads the created digital content to an off-centered storage engine entity for storage, and receives a digital fingerprint ID of the digital content returned by the off-centered storage engine entity, wherein the digital fingerprint ID is a unique identifier of the digital content. Further, when the user portal receives the NFT creation request, the user portal may send the NFT creation request and the digital fingerprint ID of the corresponding digital content to the NFT engine entity, and the NFT engine entity invokes the dgoods protocol-based NFT intelligent contract from the EOS blockchain network, and writes the parameters corresponding to the digital content and the digital fingerprint ID into the EOS multi-index table.
Having described the casting process of the NFT, the following further describes the NFT release process. Optionally, the digital asset management method further comprises the steps of:
Step 1a: an NFT issue request for the digital content is obtained.
Wherein, the NFT issue request carries at least one of the following: accepting the account, asset class, license name, issue number, relative_uri of the NFT;
step 1b: querying an EOS multi-index table stored by the EOS blockchain network in response to the NFT issue request, and determining an issuer of the digital content;
step 1c: verifying the issuer rights and performing the following loop traversal operation: generating a digital asset ID based on a singleton table of the EOS blockchain network and adding 1 to the release number until the release number is reached;
step 1d: the generated digital asset ID is written to the EOS multi index table of the EOS blockchain network.
For example, after obtaining the issue request of the NFT, the NFT engine entity may call the issue function of the migu. Token contract to issue the NFT, first obtain the issuer issuers from the category and token_name to dgoodstats tables, and verify the authority and issue number of the issuers. If the token is non-homogenous, the following loop traversal operation is performed according to the number of issues: and generating a unique digital asset ID (dgoods_id) by utilizing a single-instance table single of EOS, issuing an excessive number of self-increment 1, adding balance to a receiver, and finally writing the parameter information into an EOS multi-index table dgoodstats. Wherein, the EOS multi-index table is a global list of digital assets, and may further include, in addition to the parameters described above: holder owner and URI of the digital asset store.
Wherein all NFTs can be issued to one account and then marketed by the marketplace, and NFTs can also be issued directly to consumers purchasing through ordinary payment. When NFT is issued, the parameters need to be entered: to: the account, category and token_name of the NFT are accepted, the issue number is equal, the relative_uri of the fingerprint hash used to store the digital content is then the metadata token_uri of the NFT is base_uri+relative_uri.

step 2a: acquiring a transfer request for the digital content, wherein the transfer request carries a digital asset ID, an NFT holder and an NFT receiver corresponding to the digital content; alternatively, the digital asset ID may be one or more.
Step 2b: invoking the NFT smart contract in response to the transfer request;
step 2c: and if the NFT intelligent contract indicates that transfer is supported, transferring the digital asset of the digital content corresponding to the digital asset ID from the NFT holder to the NFT receiver.
That is, if the NFT is set to be transferable, the NFT engine entity may call transfer of migu. Token contracts to transfer the owner of the NFT to another account by specifying dgoods_id, where the parameters that need to be transferred include: from: NFT holder, to: NFT receiver, dgoods_ids, etc. Wherein the set of dgoods_ids digital asset IDs is an array type.
Optionally, the digital asset management method further comprises the steps of: step 3a: acquiring a destruction request aiming at the digital content, wherein the destruction request carries a digital asset ID and an NFT holder corresponding to the digital content; wherein the digital asset ID may be one or more.
Step 3b: responding to the destruction request, and calling the NFT intelligent contract;
step 3c: if the NFT intelligent contract indicates that the destruction is supported, destroying the digital asset of the digital content corresponding to the digital asset ID.
That is, if the NFT is set to be destructible, the NFT engine entity may call the burn function of migu. Token contract to destroy the NFT, where the parameters that need to be entered include: owner and dgood_ids.
Optionally, the digital asset management method further comprises the steps of: step 4a: acquiring a query request for querying digital assets supporting sales;
Step 4b: responding to the query request, and calling the NFT intelligent contract;
step 4c: querying the NFT smart contract for an NFT list indicating all digital assets that support sale, the NFT list including fields indicating at least one of: a seller account, a digital asset ID, and a price, wherein the digital asset ID may be one or more.
That is, the NFT engine entity may call the listsallenft function of the migu. Token contract to query all the list of NFTs available for sale, where the parameters that need to be entered include: seller: vendor account, dgood_ids, net_save_current: price, each user can query the NFT list for sale through this.
It should be noted that, the above processes of casting, issuing, transferring, destroying, querying, etc. of the NFT may generate a corresponding operation record or transaction record, and the NFT engine entity may upload the record to the database for saving.

That is, the digital asset management method further includes: creating an EOS account and initializing an NFT smart contract. Specifically, the NFT engine entity may generate a pair of public and private keys using an EOS wallet in an EOS blockchain network, import the public and private keys into the wallet, and create a new account using the super account eosio's newaccount method and the public and private keys above. Further, the NFT engine entity may also implement creation of the NFT smart contract migu.token based on the dgoods protocol, and further deploy migu.token contracts to the newly created accounts on the EOS blockchain network. In addition, the NFT engine entity may also add eosio.code rights to the migu.token contract.
Optionally, in order for the wallet to know which version of the contract to use and the sign of the asset in the contract, the NFT engine entity may call the initial configuration function of migu. Specifically, the digital asset management method further includes: uploading initialization configuration information of the NFT smart contract to the EOS blockchain network for storage, the initialization configuration information including at least one of: version number of dgoods protocol and NFT asset symbol.
