The invention provides a block chain-based asset guarantee checking and early warning method, which comprises the following steps: constructing a alliance chain, and enabling an asset ownership registration authority to send an asset certificate to an asset owner, wherein the asset certificate is provided with an electronic tag which can be read by each node in the alliance chain, and asset attribute information is recorded in the electronic tag; judging whether the target asset is mortgage or mortgage, if so, uploading mortgage or mortgage information to a alliance chain by a financial institution, and writing the mortgage or mortgage information of the target asset into an electronic tag by an asset ownership registering institution; after receiving the application of the principal to the target asset guarantee or replacement, the court node reads the electronic tag data and compares and checks the electronic tag data with the target asset information in the alliance chain to judge the authenticity of the target asset information, for example, when the asset rights registering mechanism carries out asset transfer on the owner of the target asset, the asset rights registering mechanism carries out the target asset guarantee or replacement information check, if the target asset has the guarantee or replacement, the court node is warned, and the handling of the asset transfer item of the target asset is stopped; and after receiving the alarm of the asset ownership registration mechanism, the court node checks and seals the target asset.
Description
Technical Field
The invention relates to an asset guarantee checking and early warning method, in particular to a blockchain-based asset guarantee checking and early warning method.
Background
In the court security execution process, the applicant of security provides a guarantee with the third party property, and the person to be secured (executor) takes the third party property as a replacement guarantee (similar anti-guarantee). In practice, because the information communication between the property rights registration authorities and the national court is not smooth, the risk of transferring the guaranteed assets by the third party after the security is granted and before the actual check is carried out exists, and the residual value of the replacement assets is difficult to estimate, so that the national court does not accept the replacement of the guaranteed assets by the third party.
Therefore, in order to solve the above-mentioned technical problems, a new technical means is needed.
Disclosure of Invention
In view of the above, the blockchain-based asset guarantee checking and early warning method provided by the invention can be used for performing real-time supervision and checking on the target asset, accurately checking the related information of the target asset when a third party performs asset guarantee and replacement, effectively preventing the target asset from being maliciously transferred, ensuring that a court accurately processes the guarantee, replacement and the like of the target asset, and ensuring the rights and interests of all parties related to the target asset.
The invention provides a block chain-based asset guarantee checking and early warning method, which comprises the following steps:
s1, constructing a alliance chain, wherein the alliance chain comprises court nodes, financial institution nodes, asset ownership registration institution nodes and assessment institution nodes;
s2, an asset ownership registration mechanism sends an asset certificate to an asset owner, wherein the asset certificate is provided with an electronic tag which can be read by each node in a alliance chain, and asset attribute information comprising ownership information, mortgage information and seal checking information is recorded in the electronic tag;
s3, judging whether the target asset is mortgage or mortgage, if so, uploading mortgage or mortgage information to a alliance chain by a financial institution, and writing the mortgage or mortgage information of the target asset into an electronic tag by an asset ownership registering institution;
s4, after receiving a target asset guarantee or replacement application of a principal, the court node reads the electronic tag data and compares and checks the electronic tag data with target asset information in a alliance chain to judge the authenticity of the target asset information, if the target asset is authentic, the step S5 is entered, and if the target asset is not authentic, the step S6 is entered;
s5, the court node sends a feedback request of the property value of the target asset of the same type to the evaluation mechanism node, the court node calculates the residual value of the target asset and judges whether the residual value of the target asset meets a set standard, if yes, the target asset is ensured to be ensured or replaced, and the information of ensuring the target asset to be ensured or replaced is synchronously uploaded to an asset ownership registration mechanism, if not, the step S6 is entered;
s6, the court refuses the guarantee or replacement application of the target asset by the principal;
s7, after the asset rights registering mechanism receives the warranty or replacement information of the target asset, updating the attribute information of the target asset and feeding back to the court node;
s8, if the asset rights registering mechanism carries out asset transfer by the target asset owner, the asset rights registering mechanism carries out target asset guarantee or replacement information verification, if the target asset is guaranteed or replaced, the system alarms to a court node, and simultaneously stops handling of asset transfer matters of the target asset; and after receiving the alarm of the asset ownership registration mechanism, the court node checks and seals the target asset.
Further, in step S2, the electronic tag is provided with a code uniquely corresponding to the asset certificate; when the court node reads the electronic tag information, public key and private key signature are carried out in a trusted execution environment through encoding, and verification is carried out synchronously with an asset authority;
and the asset rights registering organization has unique writing rights to the electronic tag, and other nodes of the alliance chain have reading rights to the electronic tag.
Further, the electronic tag also comprises right flaw information of the target asset.
Further, the assessment mechanism uploads in real time reference information for assessing the asset value within the same type, period and co-location set time as the target asset.
Further, in step S5, the residual value evaluation for the target asset is performed by the following method:
if the target asset does not have the mortgage, guaranty or check information, taking the actual value of the target asset as the residual value;
if the target asset has mortgage, guaranty or audit information, the remaining value of the target asset is:
(min(A1,A2)-B)×N；
where A1 is the average price of the target asset in the assessment institution, A2 is the assessment price of the assessment institution, B is the mortgage home of the target asset in the financial institution, N is whether the target asset determined by the asset equity registration institution has a check before, if so, n=0, if not, n=1.
Further, in step S8, if the target asset is requested to be transferred within the time interval between the guarantee time of the target asset and the actual seal time of the target asset, the asset ownership registration mechanism verifies whether the target asset on the federation chain has ready-to-mortgage and seal information, if yes, the asset ownership registration mechanism immediately performs early warning.
Further, in step S2, the electronic tag is an RFID electronic tag or an NFC electronic tag.
Further, the alliance chain adopts a Bayesian fault tolerance algorithm or a rayleigh network consensus algorithm.
The invention has the beneficial effects that: the invention can carry out real-time supervision and inspection on the target asset, can accurately inspect the related information of the target asset when a third party carries out asset guarantee and replacement, can effectively prevent the target asset from being maliciously transferred, ensures that the court carries out accurate processing on the guarantee, replacement and the like of the target asset, and ensures the rights and interests of all parties related to the target asset.
