In order to make the objects, technical solutions and advantages of the present disclosure more apparent, the technical solutions of the present disclosure will be clearly and completely described below with reference to the specific embodiments of the present disclosure and the accompanying drawings. It should be apparent that the described embodiments are only some of the embodiments of the present application, and not all of the embodiments. All other embodiments obtained by a person skilled in the art without making any inventive step based on the embodiments in the description belong to the protection scope of the present application.
The technical solutions provided by the embodiments of the present application are described in detail below with reference to the accompanying drawings.
The embodiment of the application provides a method and a corresponding scheme for guaranteeing the deposit interest of a user based on a block chain, and the characteristics of high technical safety and strong traceability of the block chain are utilized to supervise the deposit of the user, so that when the deposit is used due to the problem of enterprise management and management, the flow direction of property can be traced, and meanwhile, a deposit return strategy is set through an intelligent contract of the block chain, so that the deposit interest of the user is guaranteed.
Fig. 1 is a schematic flow chart of a method provided in an embodiment of the present disclosure. As shown, the method comprises:
s101, receiving a mortgage contract established between a mortgage person and a mortgage obligee, and storing the mortgage contract in a block chain;
s102, a communication interface between the block chain and a trusteeship bank is established, so that the deposit paid by the mortgage is transferred to the trusteeship bank through the block chain.
The block chain is a chain data structure formed by combining data blocks in a sequential connection mode according to a time sequence, and is a distributed account book which is guaranteed in a cryptographic mode and cannot be tampered and forged. Although the underlying technology of blockchains has been developed for many years, it has not been possible to achieve effective application in a particular scenario.
According to the embodiment of the invention, in step S101, an intelligent contract for managing deposit information is set on the blockchain, and the intelligent contract is an automatically running script deployed on the blockchain and has a transparent characteristic due to being set on the blockchain. A user presets rules through an intelligent contract so as to write data into a block chain and acquire data browsing permission, and disclosure of privacy information is avoided to a great extent. Of course, the smart contracts are not the only implementation manner of the present application, and are set correspondingly according to different blockchain platforms, such as an ethernet house, a super book, and the like.
According to the specific embodiment of the present invention, the setting of the node of the block chain is not particularly limited, and may be a related financial regulatory department, and the like.
According to an embodiment of the present invention, in step S101, the mortgage contract may be stored in the block chain by extracting data of the main body, the amount of money and the main items involved in the mortgage contract, and writing the extracted data into the block chain, and preferably, information of the items obtained by extracting data may be sent to the mortgage and the mortgage owner for confirmation, and then stored in the block chain.
According to an embodiment of the present invention, in step S102, the establishing a communication interface between the block chain and a hosting bank, so that the deposit paid by the mortgage person is transferred to the hosting bank through the block chain, includes: and establishing the communication interface according to the service agreement between the mortgage owner and the escrow bank so as to enable the mortgage owner to call part of the deposit and the interest of the deposit.
It will be appreciated that the escrow bank may be replaced by a trusted entity or the like, by providing a dedicated user deposit escrow account and communication interface between the mortgage owner and the escrow bank, so that the mortgage owner can withdraw from the trust some of the user deposits and interest in the deposits, preferably no more than 30% of the total user deposit.
According to a specific embodiment of the present invention, the method of the embodiment of the present invention further includes: the block chain receives a deposit return request sent by the mortgage; and verifying the deposit return request through the intelligent contract of the block chain, and sending a deposit return instruction to the escrow bank after the deposit return request is established.
Specifically, the instructions for verifying the request by the intelligent contract of the blockchain and sending a return deposit to the escrow bank after the request is established include: determining whether the deposit in the escrow bank meets deposit withdrawal requests of a plurality of mortgagers through an intelligent contract of the block chain; and if the deposit is not satisfied, feeding back a preset deposit withdrawal strategy to the plurality of the mortgages to enable the plurality of the mortgages to determine a deposit withdrawal mode, and if the deposit withdrawal strategy is satisfied, directly withdrawing the deposit to the mortgages.
More specifically, the deposit withdrawal mode includes: queuing for returning the deposit with the sufficient amount; and or generating an insufficient deposit through the smart contract and queuing to wait for the remainder of the deposit to be returned.
Generating the insufficient deposit may be understood as generating the corresponding insufficient deposit by recording the credit during the use of the product by the user and the performance of the contract, etc., the better the credit, the greater the amount of the insufficient deposit.
According to a specific embodiment of the present invention, the method further comprises: receiving enterprise operation condition information sent by a supervision mechanism, wherein the enterprise operation condition information is generated by the supervision mechanism according to a financial statement of an enterprise; and determining whether to close a communication interface between the block chain and the escrow bank according to the enterprise operation condition information.
Firstly, the enterprise operation information sent by the monitoring mechanism has certain public credibility, the situation that the block link receives error information to close the communication interface is reduced, and secondly, the problem that the enterprise transfers the user deposit privately can be effectively avoided through the mode.
Based on the same idea, some embodiments of the present application further provide a device and a non-volatile computer storage medium corresponding to the above method.
Fig. 2 is a schematic diagram of an apparatus framework provided in an embodiment of the present disclosure, and an apparatus for managing secured user deposit based on blockchain includes:
at least one processor; and the number of the first and second groups,
a memory communicatively coupled to the at least one processor; wherein,
the memory stores instructions executable by the at least one processor to enable the at least one processor to:
receiving a mortgage contract established between a mortgage person and a mortgage obligee, and storing the mortgage contract in a block chain;
and establishing a communication interface between the block chain and the escrow bank, so that the deposit paid by the mortgage person is transferred to the escrow bank through the block chain.
Some embodiments of the present application provide a non-volatile computer storage medium corresponding to fig. 1 for securing a user deposit based on a blockchain, the medium storing computer-executable instructions configured to:
receiving a mortgage contract established between a mortgage person and a mortgage obligee, and storing the mortgage contract in a block chain;
and establishing a communication interface between the block chain and the escrow bank, so that the deposit paid by the mortgage person is transferred to the escrow bank through the block chain.
