The system in the embodiment can realize the digitization of the traditional asset, and places the digitised traditional asset on a blockchain, verifies the intelligent contract through rights and interests, authenticates the intelligent contract, and the asset compliance authentication contract ensures that the authenticated asset is issued and circulated completely according to local laws and regulations, so that the authenticated transaction process and related data of all the digital assets can be recorded under the condition of ensuring unmanned supervision, higher transparency, traceability and security are provided, transaction cost and time are reduced, greater flexibility, market mobility and interchangeability are brought for asset management and transaction, and the problems of poor mobility and transaction limitation of the traditional asset are solved.
The terminal 101 may be, but not limited to, various personal computers, notebook computers, smart phones, tablet computers, internet of things devices and portable wearable devices, and the internet of things devices may be smart speakers, smart televisions, smart vehicle devices, and the like. The portable wearable device may be a smart watch, smart bracelet, or the like. The rights issuing platform 10 includes a KYC institution, AML money laundering regulatory authorities, and other related regulatory authorities, which are eligible for authorization and capable of issuing corresponding rights compliance credentials.
Specifically, in the system 102, the requestor may be an investor or issuer of the asset. An intelligent contract is a computing code that automatically executes contract terms. Based on the account request of the requesting party, invoking an identity intelligence contract of a blockchain in the system 102, and generating an identity account chainID for the requesting party, wherein the identity account chainID can execute transaction operation in the system 102. Wherein asset certification is performed using the ERC-20 standard or the ERC-1155 standard.
The ERC-20 standard is applicable to single asset certification. The ERC-1155 standard is a multi-asset certification standard suitable for certifying multiple different types of assets, which can manage and transact multiple asset types in the same intelligent contract. For example, the assets of a bond or equity representative may be individually digitized using the ERC-20 standard, the bond and equity combination may be issued using ERC-1155 and the commission (gas) of circulation may be reduced.
Illustratively, an ERC-20 identity smart contract is created defining the certification name, sign, total supply, and decimal point number of the digital asset. And setting transfer, balance inquiry and other functional functions in the ERC-20 identity intelligent contract. The issuer may issue a smart contract based on the ERC-20 asset, issuing a corresponding number of ERC-20 passes according to the number of bonds or equity, the ERC-20 passes being a one-to-one mapping to the bonds or equity. The investor may purchase the ERC-20 pass to gain rights to the bond or equity based on an ERC-20 identity smart contract, the number of ERC-20 passes held representing its share in the bond or equity.
Illustratively, an ERC-1155 asset issuance contract is created defining the certification type and related attributes of the digital asset. The issuer may obtain bonds or equity for digital asset ERC-1155 certification types and related attributes based on ERC-1155 asset issuance contracts and assign a unique ID and corresponding attributes to each ERC-1155 certification type. The sponsor may obtain rights to the corresponding bond or share by purchasing ERC-1155 passes for a particular ID. In addition, ERC-1155 contracts support bulk transfers, so investors can transfer multiple different types of letters at a time to reduce the handling costs (gas) of circulation.
The digital asset is authenticated by integrating the rights of individuals or institutions required by the issued asset through the intelligent contract for asset issuing constructed based on the ERC-20 standard or the ERC-1155 standard, digitizing the traditional asset, and embedding various conditions and rule intelligent contracts required by asset issuing into the digitized asset, thereby automating the management, distribution and transaction processes of the digital asset.

Specifically, after the rights and benefits compliance certificate is bound with the identity account number of the requester, the requester initiates an asset transaction request on the asset issuing platform 20 of the system 102 by using the identity account number, the asset transaction request triggers an identity intelligent contract on a blockchain, the rights and benefits compliance certificate required by the asset to be transacted in the asset transaction request is obtained, the rights and benefits compliance certificate is verified with a first rights and benefits compliance certificate for conducting asset transaction, which is possessed by the current identity account number, whether the transaction content of the asset transaction request is a compliance action under the identity account number is confirmed, a transaction verification result is obtained, if the rights and benefits compliance certificate required by the asset to be transacted is matched with the first rights and benefits compliance certificate for conducting asset transaction under the identity account number, and if the rights and benefits compliance certificate is not required by the asset transaction is not matched with the first rights and benefits compliance certificate for conducting asset transaction under the identity account number, a terminal user is reminded to conduct supplementary authentication.
Optionally, after the rights and benefits compliance certificate is bound with the identity account number of the requester, the requester initiates an asset issuing request on the asset issuing platform 20 of the system 102 by using the identity account number, the asset issuing request triggers the issuing compliance certificate required by the local government or the regulatory department predefined by the type of asset on the blockchain, the rights and benefits compliance certificate required by the asset to be issued in the asset issuing request is obtained, the rights and benefits compliance certificate required by the asset to be issued in the asset issuing request is verified with the second rights and benefits compliance certificate for issuing the asset, whether the issuing content of the asset issuing request is the compliance action under the identity account number is confirmed, the issuing verification result is obtained, if the rights and benefits compliance certificate required by the asset to be issued are matched with the first rights and benefits compliance certificate for performing asset transaction under the identity account number, and if not, the terminal user is reminded to perform supplementary verification on the missing second rights and benefits compliance certificate for issuing the asset account number.
Specifically, the request verification module 23 receives a transaction verification result returned by the identity intelligent contract, and generates and sends transaction permission information to the transaction issuing module 24 when the transaction verification result is qualified, that is, the transaction content of the asset transaction request is compliance under the identity account, and the transaction issuing module 24 completes the asset transaction based on the transaction permission information.
Optionally, the request verification module 23 receives an issue verification result returned by the identity intelligent contract, and generates and sends issue permission information to the transaction issuing module 24 when the issue verification result is qualified, that is, the issue content of the asset issue request is compliance under the identity account, and the transaction issuing module 24 completes the issue of the asset based on the issue permission information.

The multi-signature wallet address stores digital assets corresponding to the requesting party.
Specifically, after private key fragments are received by a requester, an operation end of an asset issuing platform and a management end of the asset issuing platform, the private key fragments of the requester and the operation end of the asset issuing platform participate in signing, and then the multi-signature wallet address of the requester can be frozen. And the operation end of the asset issuing platform and the management end of the asset issuing platform participate in signing with private key fragments of the requesting party, so that the transaction can be performed on the system.

The realization can realize automatic issuing circulation through intelligent contracts of all modules, and can also guarantee normal operation of transactions and guarantee benefits of all parties through intervention of an administrator on violations under the guidance of predefined rules under the condition of violations.
In one embodiment, as shown in fig. 3, the asset issuing platform 20 further includes an asset compliance verification module 26 for compliance verification of the digital asset of the multi-sign wallet address, and generating an address reliability of the multi-sign wallet address, where the address reliability is generated based on whether there is a record of the illegal transaction in the multi-sign wallet address.
And if the multi-signature wallet address has the violation transaction record and the violation transaction record is judged to be a first-level violation, the identity account is frozen. Wherein, the first-level violation refers to that the source of the transaction asset in the violation transaction record is unknown and the transaction amount is larger than a set threshold.
Or if the multi-sign wallet address has the violation transaction record and the violation transaction record is judged to be a secondary violation, acquiring the rights and interests authentication information of the identity account again for re-authentication. Wherein, the second level violation means that the transaction amount in the violation transaction record is larger than a set threshold.
And if the illegal transaction records do not exist in the multi-signature wallet address, the digital asset verification of the multi-signature wallet address is passed.
Illustratively, the asset compliance verification module 26 includes a TRM virtual currency transaction record compliance tracking system, a Chainanalysis digital asset transaction record compliance governance, and a bitcon transaction system to ensure that the asset at the certification platform fully meets regulatory requirements and to ensure asset security for both parties to the transaction.
