Fig. 2 is a schematic flow chart of the main process of the system for confirming the consistency of the assets in the chain according to the embodiment of the invention. As shown in fig. 2, the main process of the system for confirming consistency of assets in a chain according to the first embodiment of the present invention includes the following steps:
step S201: and the asset hosting system acquires a hosted asset registration index identifier in corresponding initial block information according to the to-be-linked initial block number of the linked asset information in the linked request information, and sends the hosted asset registration index identifier to the storage service system through a query request. The asset hosting system, which the user may access via the Web or otherwise, may be a system that hosts registration management of a user's under-link real-name registered assets by designated asset hosts and registration management of the process of publishing digital assets on a blockchain by the hosted assets, including both the off-link asset uplinking process and the on-link asset downlinking process. The method comprises the following steps that firstly, a user is managed by an asset management part, and then the asset management system issues digital assets on a chain to an asset account book system based on a block chain; and (4) performing the on-chain asset downgoing, namely, invalidating the digital assets of the user on the blockchain, and returning and transferring the under-chain managed assets corresponding to the digital assets to the user.
The downlink request information refers to a request that a user can initiate the return of the assets from the uplink digital assets. In an optional embodiment, the downlink request information includes: return user information and downlink asset information, etc. The returning user information includes: the user identification, the real-name account book record and the like, wherein the user refers to a user with asset downlink requirements. The downlink asset information may be asset information requested to be downlink by the user, and in an alternative embodiment, the downlink asset information includes: managed asset type, quantity of downlink assets, managed registration index information to be downlinked, initial block number to be downlinked and the like.
Wherein the initial block information includes: an initial block number and a hosting asset issuance request with an asset hosting system signature, etc.; the hosted asset issuance request includes: the managed asset registration index information with the storage service system signature, the managed asset issuing information and the like; the hosted asset registration index information includes: the managed asset registration index identification, the tamper-resistant information of the managed asset storage information and the like; the managed asset retention information may be considered comprehensive managed asset information stored in the storage service system, relating to the return of the down-link asset to the up-link asset hosting or down-link asset hosting, and confirming that the asset hosting party is the authorized person of the managed asset, and in an alternative embodiment, the managed asset retention information includes: the certificate information of the electronization or pure electronization of the paper document; the managed asset release information refers to release information when an asset under a chain is managed to the chain, and includes: managed asset class, managed asset description information, authority address, number of asset issuing units, etc. The asset hosting system acquires corresponding initial block information according to the initial block number to be linked down, and inquires corresponding hosted asset storage information from the storage service system based on the hosted asset registration index identification of the hosted asset registration index information of the hosted asset issuing request of each acquired initial block information.
Wherein, the tamper-resistant information is: and the hosting asset stores the digital fingerprint information of the information, or utilizes the asset hosting system and the storage service system to sign the digital fingerprint information. The digital fingerprint information is information obtained by performing an operation on the managed asset storage information by using a certain algorithm, for example, a hash value obtained by performing a hash operation on the managed asset storage information. It should be noted that the digital fingerprint information may also be information obtained by calculating the managed asset storage information by using other algorithms, as long as the calculated information uniquely corresponds to one managed asset storage information.
Step S202: and the storage service system inquires managed asset storage information corresponding to the initial block number to be linked down according to the managed asset registration index identification in the inquiry request and verifies the managed asset storage information, and after the verification is passed, the inquired managed asset storage information is fed back to the asset hosting system. The storage service system in the embodiment needs to be secure and trusted, and may be a cloud storage service system, one device with a storage function, or a system formed by connecting a plurality of devices with a storage function through a network.
Step S203: and the asset hosting system sends the hosted asset storage information to the asset hosting party to request to be checked and verified with the asset right registration system. And the storage service system feeds the inquired managed asset storage information back to the asset hosting system, and the asset hosting system sends the managed asset storage information to the asset host to request to be checked and verified with the asset right registration system.
Step S204: the asset hosting party accesses the asset right registration system and inquires and checks the received hosted asset preservation information to judge whether the asset right hosted transfer information of the hosted asset preservation information is consistent with the corresponding information of the asset right registration system, and if so, the step S205 is executed; if not, go to step S206. The asset hosting party can be a qualified organization with a certain public trust strength, such as a commercial bank and a business system thereof; the asset hosting party can be an entity for receiving hosted assets and can adopt legal relationships such as funds and the like; in some practical cases, the entity may manually process the information. The asset rights registration system is a traditional asset rights registration system under the chain.
Step S205: and the asset hosting party sends the downlink request information with the asset hosting party signature to the asset hosting system and requests to perform downlink asset freezing operation. In the process, the managed asset storage information of the storage service system is compared with the information of the asset right registration system, if the managed asset storage information of the storage service system is consistent with the information of the asset right registration system, the verification is passed, and the asset management side has the right to return the asset specified in the downlink request information to the user. The down link request information at this time has the asset application terminal system, the asset hosting system and the three-party signature of the asset hosting party.
Step S206: the asset hosting party returns a notification to the asset hosting system that the downlinked operation failed. In the process, the managed asset storage information of the storage service system is compared with the information of the asset right registration system, and if the managed asset storage information and the information of the asset right registration system are not consistent, the managed asset storage information and the information of the asset right registration system indicate that the managed asset storage information and the information of the asset right registration system are abnormal in the managed process and the downlink operation fails.
In a preferred embodiment, after step S203 is completed, the asset host may further confirm whether the asset owner in the asset rights hosting transfer information in the asset saving information is the asset host. If the asset owner is not the asset host, the asset host does not have the right to return the asset specified in the downlinked request message to the user, and a notification of the failure of the downlinked operation can be returned to the asset hosting system.
Example two: as can be seen from the first embodiment, the asset application terminal system needs to obtain the hosted asset registration index identifier in the corresponding initial block information according to the to-be-linked initial block number of the linked asset information in the linked request information, so as to query the corresponding hosted asset storage information in the storage service system. The downlink request information is generated by the asset application terminal system, so that the asset application terminal system needs to receive the downlink request information from the asset application terminal system and then perform subsequent processing. The following will explain in detail with reference to example two.
Fig. 3 is a schematic main flowchart of the system for confirming the consistency of the assets in the chain according to the second embodiment of the present invention. As shown in fig. 3, the main flow of the system for confirming consistency of assets in a chain according to the second embodiment of the present invention includes the following steps:
step S301: and the user accesses the asset application terminal system installed on the terminal equipment, submits the identification information according to a preset login identification mode and logs in the asset application terminal system. The asset application terminal system is system software which is installed on the terminal equipment and corresponds to the asset ledger system; a user may download and install asset application end system software from an asset hosting system by accessing the asset hosting system. The terminal device may be various electronic devices having a display screen and supporting web browsing, such as a mobile phone, a tablet computer, a desktop computer, and the like. The asset account book system is based on a block chain technology, and verification, query, record and other operations can be realized by the common recognition nodes on the chain. The login identification mode may be a user name and password identification mode, a fingerprint identification mode, a face identification mode, and the like, and the corresponding identification information may be: a user name and a password, or an identification code in a preset format corresponding to the user name. The identification code in the preset format may be a password in the form of characters, or may be a biometric identification code, such as a fingerprint, facial information, iris information, etc. of the user.
Step S302: and after the asset application terminal system determines that the user is a real-name user of the associated asset account book address, acquiring a real-name account book record corresponding to the user from the asset hosting system. The asset hosting system stores real-name account book records corresponding to the users. Wherein, real-name account book record includes: an identity certificate associated with identity information of a user and an asset ledger address associated with identity information of a user, the identity certificate comprising: the identity of the user and the user public key. The identity certificate may be a CA (certificate Authority) certificate provided for information non-repudiation. .
The user public key and the user private key are generated by the asset application terminal system locally by adopting an asymmetric encryption algorithm. The user private key can be used for signing data information such as user identity information, user bank card information, user biological identification code information or user identity certificate and the like, and can also be used for signing digital asset information in subsequent asset transaction or financing process so as to confirm ownership of transaction; the user public key can be used for correspondingly verifying the data information signed by the user private key.
Step S303: and the asset application terminal system displays the downlink operation entrance corresponding to the asset category to the user through the terminal equipment. In the embodiment of the invention, the digital assets are classified in advance, and each type of digital assets corresponds to a unique asset class number. The digital assets comprise divisible digital assets and indivisible digital assets, wherein the divisible digital assets refer to managed assets contained in the initial blocks and can be divided under a chain, such as stocks, gold and the like; the indivisible digital assets refer to managed assets contained in the initial block which cannot be divided under the chain, such as houses, cultural relics, copyright, golden amalgamation and the like. When two assets belong to the same type of divisible digital assets, operation can be carried out between the two assets. Even if two inseparable digital assets belong to the same category, no operation can be performed between the two assets, for example, although both the digital asset property a and the digital asset property B belong to the property category, no operation can be performed between the two assets. The asset class number can be used for determining whether the assets belong to divisible digital assets or indivisible digital assets, and the down-link clearing is convenient.
Step S304: the user selects the downlink operation entrance, selects and/or inputs the downlink asset quantity through the terminal equipment. And the user selects a downlink operation entry corresponding to a certain asset class, the asset application terminal displays real-name identity information of the user after confirming that the user is a real-name user, and the user selects the quantity of the downlink assets and confirms to perform downlink operation.
Step S305: and the asset application terminal system generates downlink request information based on the downlink asset quantity, and sends the downlink request information with the signature of the asset application terminal system to the asset hosting system. Wherein the downlink request information includes: returning user information, downlink asset information and the like, wherein the returning user information comprises the following steps: user's ID and real-name account book record etc. down-link asset information includes: managed asset category, quantity of downlink assets, managed registration index information to be downlinked (in the embodiment, the information is stored in a list form), initial block number to be downlinked and the like. The specific implementation of generating the downlink request information is as follows: firstly, according to a real-name ledger record, acquiring on-chain asset information corresponding to an asset ledger address of the real-name ledger record, wherein the on-chain asset information comprises the asset quantity corresponding to the asset ledger address and on-chain asset hosting registration index information (in the embodiment, the information is stored in a list form); then, a group of initial block information is selected from the initial block information corresponding to the on-chain asset hosting registration index information, so that the sum of the effective asset unit number contained in the selected initial block information is the same as the quantity of the down-chain assets, the initial block number corresponding to the selected initial block information is used as the initial block number to be down-chain, the on-chain asset hosting registration index information corresponding to the selected initial block information is used as the index information to be down-chain hosted registration, and the down-chain request information is generated based on the quantity of the down-chain assets, the index information to be down-chain hosted registration and the initial block number to be down-chain. The effective asset unit quantity is the result of the quantity of asset issue units minus the quantity of asset units that are terminated.
Step S306: the asset hosting system acquires a hosted asset registration index identifier in corresponding initial block information according to the to-be-linked initial block number of the linked asset information in the linked request information, and sends the hosted asset registration index identifier to the storage service system through a query request. The specific implementation of this step is the same as step S201.
Step S307: and the storage service system inquires and verifies the managed asset storage information corresponding to the initial block number to be linked down according to the managed asset registration index identification in the inquiry request, and feeds the inquired managed asset storage information back to the asset hosting system after the verification is passed. This step is the same as step S202.
Step S308: and the asset hosting system sends the hosted asset storage information to the asset hosting party to request to be checked and verified with the asset right registration system. The specific implementation of this step is the same as step S203.
Step S309: the asset hosting party accesses the asset right registration system and inquires and checks the received hosted asset preservation information to judge whether the asset right hosted transfer information of the hosted asset preservation information is consistent with the corresponding information of the asset right registration system, and if so, the step S310 is executed; if not, go to step S311. This step is the same as step S204.
Step S310: and the asset hosting party sends the downlink request information with the asset hosting party signature to the asset hosting system and requests to perform downlink asset freezing operation. The specific implementation of this step is the same as step S205.
Step S311: the asset hosting party returns a notification to the asset hosting system that the downlinked operation failed. The specific implementation of this step is the same as step S206.
