Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.
Publishing an under-chain asset as an on-chain digital asset typically requires a process of under-chain asset hosting transfer, under-chain asset entitlement confirmation, under-chain asset hosting registration, and publishing as an on-chain asset. The purpose of hosting the transfer is to host the down-chain asset to the asset hosting party for subsequent up-chain operations on the down-chain asset. The purpose of asset validation is primarily to ensure that the user has valid possession of the down-link asset and that the user has already managed all of the down-link assets that are to be hosted on the uplink to the asset hosting party. The main purpose of the escrow registration is to facilitate the inquiry and verification of the down-link asset during subsequent uplink operations, and to ensure the validity of the down-link asset to be linked so that the down-link asset is published as an on-link digital asset.
The invention provides a managed registration system and a method of an under-link asset to be linked.
According to an aspect of an embodiment of the present invention, there is provided a hosted registration system for a downlink asset to be linked.
FIG. 1 is a schematic diagram of the main components of the system for custody registration of an under-link asset to be linked. As shown in fig. 1, a hosted registration system 100 for a downlink asset to be linked according to an embodiment of the present invention includes: an asset hosting system 101 and a storage service system 102; wherein,
the asset hosting system 101 generates hosted asset information according to the right transfer result information of the to-be-linked down-link asset hosted to the asset hosting party, signs the hosted asset information and sends the signed hosted asset information to the storage service system 102;
the storage service system 102 verifies the signature of the asset hosting system 101, stores the hosted asset information with the asset hosting system signature after the verification is passed, generates registration index information according to the hosted asset information, signs the registration index information and sends the registration index information to the asset hosting system 101;
the asset hosting system 101 verifies the signature of the storage service system 102 and the registration index information, and registers the registration index information after the verification is passed, so as to implement the hosting registration of the linked asset to be linked up.
A escrow party refers to a principal for an asset under the escrow chain, such as a fund, a trusted product, and so forth. The asset hosting system can be a system for hosting and managing the real-name registered assets under the chain by a user through a designated hosting party and for registering and managing the process of issuing the digital assets on the block chain by the hosted assets; the user may access the asset hosting system via the Web or otherwise.
The storage service system may be a cloud storage system, or may be another system having a storage function.
After the user transacts the transfer of the down-chain asset hosting system to the asset hosting system, right transfer result information can be sent to the asset hosting system through the asset application terminal to indicate that the user has hosted the down-chain asset to the asset hosting system. The asset application terminal system is security software and hardware installed on the terminal equipment. The terminal device may be various electronic devices having a display screen and supporting web browsing, including but not limited to smart phones, tablet computers, laptop portable computers, desktop computers, and the like.
The right transfer result information is information indicating whether the asset under the chain is completely transferred to the asset hosting party, and may be description information or related vouchers generated after the transfer, such as asset right transfer vouchers, vouchers of the asset hosting party for holding the asset, and the like. And the related certificate is stored in the storage service system, so that later inquiry and audit are facilitated.
According to the invention, the chain-down asset is managed and registered before being released as the chain-up asset, so that the chain-down asset can be conveniently inquired and verified during subsequent chain-up, the effectiveness of the chain-down asset to be chain-up can be ensured, the chain-down asset can be conveniently released as the chain-up digital asset, and the chain-up of the traditional chain-down asset in a hosting way is realized.
The hosted asset information may include: the method comprises the steps of asset hosting uplink request information with signatures of two parties of a user and an asset hosting system, and right transfer result information with signatures of three parties of the user, the asset hosting party and the asset hosting system.
The asset managed uplink request message corresponds to the managed uplink protocol. In some embodiments, the asset hosting system initiates its signed hosting uplink protocol, the user confirms the protocol content through the asset application terminal system and returns to the asset hosting system after signing up, and the asset hosting system notifies the user to handle the transfer of the linked asset hosting to the asset hosting system after confirming the protocol content. In other embodiments, the user sends the signed mandated upper chain agreement to the asset hosting system through the asset application terminal system, and after the asset hosting system confirms the user asset right, the asset hosting system confirms the agreement content and signs a contract, and then informs the user to handle the operation of transferring the down-chain asset hosting to the asset hosting system. Whether a user directly initiates a managed uplink protocol through an asset application terminal system or the asset hosting system initiates the managed uplink protocol, the managed uplink protocol carries signatures of both the asset application terminal and the asset hosting system, so that the asset hosting relationship of the down-link asset can be confirmed subsequently according to the signatures of both the asset application terminal and the asset hosting system.
The right transfer result information is provided with the signatures of the user, the asset hosting party and the asset hosting system, so that the transfer transaction and the hosting participating parties are confirmed, errors are prevented, and errors in the hosting asset information generated based on the right transfer result information during uplink are avoided.
In some embodiments, before the asset hosting system sends the hosted asset information to the storage service system, the asset hosting system signs the hosted asset information and sends the hosted asset information signed by the asset hosting system to the asset application terminal system; the asset application terminal system displays the signed managed asset information of the asset hosting system to a user, and signs the signed managed asset information of the asset hosting system again after the user confirms; the asset hosting system sends the re-signed hosted asset information to the storage service system. Both the asset application terminal system and the asset hosting system are signed before storage, facilitating subsequent confirmation of the asset hosting relationship. But not necessarily. Because the managed asset information is provided with the right transfer result information confirmed by the down-link asset right registration system, and before the user finishes the asset transfer, the asset application terminal and the asset hosting system have double-signed managed uplink protocol.
Optionally, the registration index information includes: an index identification for retrieving the hosted asset information, and tamper-resistant information for verifying the hosted asset information. The storage service system is adopted to store the asset hosting information, and the asset hosting system only stores the index identification, so that on one hand, the system safety can be improved, on the other hand, the storage burden of the asset hosting system can be greatly reduced, the operation efficiency of the asset hosting system is improved, and in addition, the asset hosting system is convenient to inquire the storage system according to the index information registered by the hosted asset. The setting of the tamper-proof information can play a role in verifying the stored information against tampering. The content of the tamper-resistant information may be selectively set according to an actual situation, and optionally, the tamper-resistant information is: the method comprises the steps of hosting digital fingerprint information of asset information or signing the digital fingerprint information by utilizing an asset hosting system and a storage service system. The digital fingerprint information refers to information obtained by performing an operation on the managed asset information by using a certain algorithm, for example, a hash value obtained by performing a hash operation on the managed asset information. It should be noted that the digital fingerprint information may also be information obtained by calculating the managed asset information by using other algorithms, as long as the calculated information uniquely corresponds to one managed asset information.
