Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, 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 some, but not all, embodiments of the present invention.
The following describes the digital asset registration method provided by the present invention with reference to fig. 1 and 2. The assets referred to in the embodiments of the present invention refer to physical assets, such as: paintings, houses, cups, etc.
Step S101: carrying out Hash operation on data information of assets to generate data fingerprints of the assets
The data information for the asset includes a contract document. The contract document including an indication of agreement to deliver the asset to the registry server operator; or information indicating a buyer to whom the asset is eligible to be delivered to the asset, as indicated by the owner of the registration server. For example: a scanned file of an asset transfer contract signed by an owner of the asset; or a signature file carrying an electronic signature of the owner of the asset; and so on. The contract document may be signed by the owner of the asset and the operator of the registration server, or may be signed by a third party authority authenticated by the owner of the asset and the operator of the registration server. The contract documents referred to herein have legal force.
In addition, the data information of the assets can also comprise some introductions of the assets condition, the certification information of the ownership, and the like. For example: the data information for the property may include the address of the house, the area of the house, the property certificate number and some related certificates; but also can include house live-action photos, house property certificate scanning pieces and the like; the data information for the painting may include the name of the work, the author, the year, whether the work is good or not, a photograph or a scanned piece of the work, a certificate issued by the relevant department (a certificate of a genuine article issued by an auction house), and the like.
In this step, a shasum command may be used to perform a hash operation on the data information of the asset, so as to generate a hash value of the data information of the asset. Wherein the hash value is the data fingerprint of the asset.
For example, the command for hashing the data information of the asset using the SHA256 hashing algorithm is as follows:
shadow-a 256 test.xml; xml is data information of an asset
The following hash values are generated by the SHA256 hash operation described above:
a9318dd76447ceea10c2953ee819b5d21cd063e0c753c157fd406b9c362de669
wherein the data information of the asset may be provided to the enrollment server via the user interface, the data fingerprint being a 64 byte string.
Step S102: embedding the data fingerprint of the asset into transfer information, and sending the transfer information to a transfer packaging server
In this step, the transfer information includes a mother address, a reception address, transfer object information, and the number of transfer objects; the master address refers to the initial address of the number of the transfer objects corresponding to the data fingerprint, the receiving address refers to the receiving address of the number of the transfer objects corresponding to the data fingerprint, and the information of the transfer objects comprises the data fingerprint of the asset.
It should be noted that the receiving address is an address where the user can perform a transfer transaction after registering the physical asset; in the embodiment of the invention, the final source of the transfer object quantity corresponding to all the receiving addresses is the mother address.
The transfer object information further includes asset additional information for any one or more of: a blockchain tag to which the asset's data fingerprint belongs, a status identification of the asset, a last price transferred for the asset, and a monetary identification of the last price transferred. The transfer object information is a string of 80 bytes or less, for example, 64 bytes of data fingerprint plus 16 bytes or less of the above-mentioned asset additional information.
It should be noted that the transfer information is the transfer information with the transfer address as the parent address and the transfer information is the legal transfer information.
For example, the registration server may embed the data fingerprint of the asset into transfer information, e.g., the OP _ RETURN byte, using a register Association (embedding command) and send the transfer information to the transfer packaging server to effect the transfer of the asset with the following commands:
RegisterAssets 1J4hLts82hNBXEothfDmGX2b8hUoxZN5gP
1JKZTtav8W5QtW9Q2hSmPNPPjwbi5yJwFQ 0.00000001
a9318dd76447ceea10c2953ee819b5d21cd063e0c753c157fd406b9c362de669false
it should be noted that 1J4hLts82hNBXEothfDmGX2b8hUoxZN5gP is the mother address of the registration server; 1JKZTtav8W5QtW9Q2hSmPNPPjwbi5yJwFQ is a receiving address; a9318dd76447ceea10c2953ee819b5d21cd063e0c753c157fd406b9c362de669 is the data fingerprint of the asset and 0.00000001 is the quantity of the asset. Where 0.00000001 represents the minimum unit, that is, 0.00000001 may represent the number of assets corresponding to one data fingerprint. The above-mentioned transfer order is only an example, and the embodiment of the present invention does not limit the transfer order.
The transfer object assets in the embodiment of the invention are physical assets, the data fingerprints generated after the hash operation is carried out on the data information of the physical assets, and the measuring units of the number of the transfer objects corresponding to the data fingerprints are the number, the set number, the breadth number, the auxiliary number, the number and the like.
Step S103: the transfer account packing server packs the transfer information according to the packing rule of the block chain, and after a timestamp is covered, the transfer account packing server broadcasts the transfer information in the whole network
In the above steps, after the transfer information containing the data fingerprints is sent to a transfer packaging server, the transfer packaging server packages the transfer information according to the packaging rule of the block chain, and after a timestamp is covered, the whole network broadcasting is carried out.
Fig. 2 is a block diagram of a digital asset registration server based on a blockchain according to an embodiment of the present invention, as shown in fig. 2.
In fig. 2, the registration server 201 sends the transfer information to the transfer packaging server 203 through the hub 202 of the blockchain, and then the transfer information is packaged by the transfer packaging server. The purpose of packing is to pack the transfer information into blocks, namely to enable the physical assets corresponding to the data fingerprints in the transfer information to be traded through a block chain.
The registration server is a server of the endorsement authority for some assets. For example: a server at a house authority, a server at a exchange, a server at a bank, or other server that provides asset registration services, etc.
It should be noted that when the digital asset corresponding to the data fingerprint is damaged or invalid, the data fingerprint is transferred to an address without the private key, and the digital asset corresponding to the data fingerprint stops transferring in the blockchain, i.e. the digital asset is "burned" or is cancelled. For example: when an antique vase is broken, the antique vase can not transfer money any more, so that the data fingerprint corresponding to the antique vase is transferred to an address without a private key.
Fig. 3 is a schematic structural diagram of a block chain-based digital asset registration server according to an embodiment of the present invention. As shown, a blockchain-based digital asset registration server includes a computing module, an embedding module, and a transmitting module.
In the server, the computing module is used for performing hash operation on data information of an asset to generate a data fingerprint of the asset; the embedding module is used for embedding the data fingerprint of the asset into transfer information; and the sending module is used for sending the transfer information to a transfer packaging server, and the transfer packaging server packages the transfer information according to the packaging rule of the block chain, and performs whole-network broadcasting after covering a timestamp.
According to the embodiment of the invention, the data fingerprint is generated by carrying out Hash operation on the data information of the real asset, the data fingerprint is embedded into the transfer information and is sent to the transfer packaging server, the transfer packaging server packages the transfer information according to the packaging rule of the block chain, and the transfer information is broadcasted in the whole network after being covered with the timestamp. By the embodiment of the invention, the transfer transaction of the physical assets can be carried out.
