FIG. 1 is a flow chart of a method of renting a property in one embodiment of the invention, including the steps of:
step S1, house source information is uplink: the method comprises the steps that a property leasing node obtains property information provided by a lessor, generates a unique identifier, generates a property block by the unique identifier and the property information, uplinks the property block in a block chain system to form a new block chain, and records the unique identifier, the property information and a hash value in the uplinked property block in a preset uplinked list.
The blockchain system is a system based on the blockchain technology, also called as a distributed ledger technology, and is an internet database technology. The method is characterized by decentralization, disclosure and transparency, so that each user can participate in maintaining database records. The blockchain system mainly comprises a network layer, a consensus layer, a data layer and the like. Blockchain systems are novel application modes of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanisms, encryption algorithms, and the like. The data layer encapsulates the underlying data blocks and related basic data such as data encryption and time stamping and basic algorithms, and the underlying data blocks are presented in a chain structure, i.e. the blockchain is a chain data structure formed by sequentially connecting data blocks in time sequence, and is a distributed account book which is not tamperable and not falsified in a cryptographic manner.
The distributed record is that any one of the property leasing systems which can record the lease information in the property agency is set as a certain node in the block chain system, the node is a property leasing node, the property information is recorded, a property block is generated and is uplinked in the block chain system, the property information is recorded instead of a centralized mechanism, and the distributed storage is that the data can be stored in all nodes which participate in maintaining the data, and not in the centralized mechanism node.
And presetting a uplinked list in a database by all nodes in the blockchain system, wherein the uplinked list comprises unique identifiers, house source information and hash values corresponding to all blockchains, and recording the unique identifiers, the house source information and the hash values corresponding to the uplinked house source blocks in the uplinked list after the house property leasing nodes finish the uplinking.
The house source information in this step may include house source details including a house source address, lessor information, a house area, and a rent, and status information including three statuses that can be leased, and not allowed to be leased.
The unique identification may be a real estate right number or an inauthentic right number, or may be a real estate source address or a unique code generated by a code generator, as long as the uniqueness of the real estate source information can be determined.
The hash value is the hash value of the last block in the chain in the blockchain corresponding to a piece of room source information.
The process of linking up a room source block when it is linked up in a blockchain system is the process of storing the room source block in the data layer of the blockchain system.
Step S2, house source information display: and the property leasing node displays all the property information in the uplink list in a preset property viewing interface.
In order to allow lessees to view the house source information, a house source viewing interface is preset at each house source leasing node, and all the house source information stored by the house source leasing node is displayed through the house source viewing interface. The tenant can see the house, negotiate with the tenant, etc. through the house agency of the house renting node. When the lessee and lessor reach a house lease transaction, the next step is performed.
Step S3, renting rooms and linking up with the chain: the house renting node receives a house renting contract containing renters, lessees and intermediary electronic signatures, the house renting contract contains unique identifiers, the house renting node generates a contract block from the house renting contract and house source information corresponding to the unique identifiers, the contract block is linked in a block chain system and is linked to a hash value corresponding to the unique identifiers through a chain structure of the block chain system to form a new block chain, and the house renting node records the house renting contract in a linked list.
The house renting node can be preset with a house renting contract receiving interface, a house renting contract uploading interface can be additionally arranged on a house source information interface in a house source checking interface, and an electronic signature system of the house renting contract can be preset so that renters, lessees and intermediaries can sign the house renting contract.
In this step, the house lease contract includes, in addition to the unique identifier, contract details including lessor information, lessee information, intermediary information, house area, lease, payment method, payment record, and deadline.
In the embodiment, in the conventional property renting process, the property information and the contract information are recorded through the nodes of the blockchain system, the property information is unique, a lessor does not need to hang more than one room, a lessee does not need to search for a plurality of intermediaries to search for the property, and all the nodes in the blockchain system can check the property information. Because the information of the house property leasing nodes is consistent, the intermediary party is changed from the comparison information to the comparison service, and the service quality of the house property leasing market is improved.
In one embodiment, after the house renting node is completely uplink, the uplink house source block or the contract block is also broadcast to other nodes in the blockchain system, after the other nodes receive the broadcast, the house source information and the hash value corresponding to the house source block are updated to the uplink list of the respective node, and the other nodes record the house renting contract corresponding to the contract block to the uplink list of the respective node.
All nodes in the blockchain system are preset with the uplink list, and the uplink list of each node should be synchronous, i.e. the house source information is consistent. Therefore, after a certain node finishes the uplink, the uplink block is broadcasted, and after other nodes receive the broadcast, the uplink list in each node is synchronously updated or recorded. In this embodiment, all the room source information in all the blockchain systems can be checked only at a certain node, and the room source information is the latest information.
In one embodiment, in step S1, the unique identifier and the room source information are generated into a room source block, and before the room source block is uplink in the block chain system, as shown in fig. 2, the room property leasing node further determines whether the room source information is the unique room source:
step S101, comparing the unique identification: and comparing the generated unique identifier with all the unique identifiers in the uplink list by the property leasing node, generating a property source block by the unique identifier and the property source information when the unique identifier is not in the uplink list, uplink the property source block in the block chain system, so as to generate a block chain of the property source information, and recording the unique identifier, the property source information and the hash value corresponding to the uplink property source block in the uplink list.
In order to ensure the uniqueness of the room source information to be uplinked by the room lease node and avoid the problem of multiple uplinking of the same room source information, the step judges whether the room source information is the uplinked room source information or not by comparing the unique identifier generated by the room lease node with all the unique identifiers in the uplinked list, and considers that the room source information is not uplinked when the unique identifier is not in the uplinked list, and the room lease node continues to generate a room source block and uplinking work. After the uplink is completed, the house property leasing node also records the unique identifier, the house source information and the hash value corresponding to the house source block which is just uplink in the uplink list for the synchronization and unification of the data.
Step S102, judging house source information: when the unique identifier is contained in the uplink list, whether the house source information is the same as the house source information corresponding to the unique identifier in the uplink list is continuously judged, and if so, the house source information is not uplink by the house property leasing node.
When the unique identifier is contained in the uplink list, the house source information is considered to be uplink, at the moment, whether the uplink house source information is the same as the house source information provided by the lessor and acquired by the house property leasing node is continuously judged, if so, the information is the same house source information, and in order to avoid repeating the uplink, the house property leasing node does not uplink the house source information.
Step S103, uplink: if the property leasing node is different, the property leasing node generates a property source block from the unique identification and the property source information, the property source block is uplinked in a block chain system, the property source block is connected to a hash value corresponding to the property source information through a chain structure of the block chain system, a new block chain is formed, and the property source information and the hash value are updated into an uplinked list.
When the house source information of the uplink is judged to be different from the house source information provided by the lessor acquired by the house property leasing node, the condition that the lessor updates the house source information is considered, the house source information is not repeatedly uplink, but the updated information is connected to the block chain which is already uplink, and at the moment, the house property leasing node continues to generate a house source block and uplink work. After the uplink is completed, for synchronization and unification of data, the house property leasing node also updates the house source information and the hash value corresponding to the house source block which is just uplink to the uplink list.
In order to determine the uniqueness of the house source information to be linked, the embodiment compares and judges the unique identification with the house source information, and ensures the uniqueness of the house source information of the link, so that the latest unique house source can be checked on any node, and the phenomenon of one house with multiple hanging is avoided.
In one embodiment, the house source information includes status information, the status information includes three states of rentable, rented or not allowed, the status information is set to a rentable state before the house source node generates a house source block from the unique identifier and the house source information, and the house source information is updated to the on-link list, and the status information is set to a rented state before the house source node generates a house source block from the house source contract and the house source information corresponding to the unique identifier, and the house source information is updated to the on-link list.
The status information of the embodiment can clearly show the condition of the house source information, and the lessee can know the current situation of the house source information through the status information, and when the house source information is displayed on the subsequent house source viewing interface, the status information can also be used as a selection item for the lessee to view, the house source information is screened, for example, only the house source information in the rentable state is viewed on the house source viewing interface.
In one embodiment, as shown in FIG. 3, the lease payment process between a lessee and lessor may take the following steps:
step S401, paying rents: the financial service node receives a payment request initiated by a lessee, wherein the payment request comprises a lessor fund account, rent and a unique identifier, and pays the rent to the lessor fund account according to the payment request.
In the blockchain system, any financial service system realizing the payment function in the financial institution is set as a node of the blockchain system, and the node is a financial service node. The financial service system may be a system that provides financial services for insurance companies, banks, loan companies, or the like. The financial service node participates in the blockchain system to check house source information and the like in the blockchain system, and provides services such as cash flow loans and the like for lessors. The financial service node can also check the payment mode and payment record of the house lease contract, and provide the lessee with the subsequent services such as credit card. In this step, the financial service node provides cash flow services for lessees and lessors.
Step S402, payment record chaining: the financial service node records the content of the payment request into a payment record of a house lease contract corresponding to the unique identifier, generates a payment block from the house lease contract and house source information containing the payment record, uplinks the payment block in a blockchain system, and links the payment block to a hash value corresponding to the unique identifier through a chain structure of the blockchain system to form a new blockchain.
All nodes in the blockchain system are preset with a uplinked list, and the uplinked list of each node should be synchronous, namely, house source information is consistent. The financial service nodes are also nodes in the blockchain system, so that the uplink list is preset in the financial service nodes. The uplink list contains all the uplink house source information, unique identification, hash value, house lease agreements and the like. Before the financial service node is uplink, the corresponding house lease contract in the uplink list of the node is acquired through the unique identification, the content of the payment request is recorded in the payment record of the house lease contract, and then the house lease contract and the house source information are generated into a payment block and are uplink, so that other nodes in the block chain system can check the specific payment record.
Step S403, broadcast payment block: after the financial service node finishes the uplink, the uplink payment block is also broadcast to other nodes in the block chain system, and the other nodes update the payment records to the uplink lists of the respective nodes after receiving the broadcast.
Other nodes in the blockchain system can synchronously update payment records into the uplink list of the respective node by broadcasting.
In this embodiment, any financial service system that realizes the payment function in the financial institution is set as the financial service node of the blockchain system, and there may be a plurality of financial service nodes in the blockchain system, so that the lessee can select any financial service node to complete the lease payment, and the lessor can select any financial service node to exchange funds, so that the whole lease payment process is transparent. The financial service node can provide subsequent financial services for the lessees according to the lease payment condition. Government agencies may also oversee, define responsibilities, through blockchain systems.
In one embodiment, as shown in FIG. 4, the government agency's regulatory process may take the following steps:
step S501, the supervision node displays house source information: and the supervision node displays all the room source information in the supervision node in a preset room source checking interface.
In a blockchain system, any one of government regulations is set as a node in the blockchain system, which is a regulatory node. The supervising node is also pre-provided with a list of already-wound links. The uplink list contains all the uplink house source information, unique identification, hash value, house lease agreements and the like. And the supervision node displays the house source information in the uplink list and provides supervision data for supervision personnel.
Step S502, illegal contents are uplink: the monitoring node receives house source violation information sent by a monitoring person, the house source violation information comprises violation content and unique identification, the monitoring node modifies the state in the house source information corresponding to the unique identification into a state of not allowing renting, the monitoring node generates a monitoring block from the violation content, the unique identification and the house source information, the monitoring block is in a chain-in-block system and is in chain connection with a hash value corresponding to the unique identification in the chain-in list through a chain structure of the chain-in-block system, and a new chain-in-block is formed.
And a house source violation information input field or an uploading interface can be additionally arranged on a house source information interface of a house source viewing interface of the supervision node. When a supervisor views certain room source information through the room source viewing interface, the supervisor can directly record illegal contents for the room source information. The supervision node has the authority for prohibiting the renting of a piece of room source information, the authority is embodied in the state information of the room source information, and when the state information is modified to be in a state of not allowing renting, the supervision node is defined as the violation of the room source information and is required to be disconnected. Therefore, after receiving the house source violation information, the supervision node modifies the state information and links the state information to be checked by other nodes in the blockchain system.
Step S503, broadcasting the supervision block: after the supervision node is completely uplink, the uplink supervision block is also broadcasted to other nodes in the block chain system, the other nodes update the house source information to the uplink list of the respective node after receiving the broadcast, and the illegal contents are recorded to the uplink list of the respective node.
Other nodes in the blockchain system can synchronously update the illegal contents to the uplink list of the respective nodes in a broadcasting way.
In the embodiment, any one of government supervision systems is set as the supervision node in the blockchain system, a plurality of supervision nodes can be arranged in the blockchain system, the supervision node can check the house source information through the blockchain system, and can also carry out subsequent statistics on the house source information, and for the house source information which does not accord with rules, the violation content is added, so that the aim of conveniently supervising and renting houses in real time is fulfilled. The block chain system comprises government supervision, so that the benefits of both lessors and lessees can be guaranteed.
In one embodiment, after the property leasing node records the property source information containing the illegal content, the property leasing node downloads the property source information containing the illegal content from the property source viewing interface, and the property leasing node displays the property source information which does not contain the illegal content in the uplink list in the property source viewing interface.
The house source information containing the illegal contents is defined as that the house renting process cannot be carried out, so that the house source information without the illegal contents is displayed in the house source viewing interface by the house renting node for viewing by a lessee. And the room source information containing the offending content is taken off line from the room source viewing interface.
The embodiment embodies the supervision result after the government participates in the blockchain system, and realizes the aim of checking the house source information from the source of the renting house, namely, the lessee, so as to avoid the possibility that the source of the renting house is rented.
In one embodiment, as shown in fig. 5, five nodes are included in the blockchain system, namely, a property leasing node 1, a property leasing node 2, a financial service node 3, a financial service node 4 and a supervision node 5. The five nodes are all preset with a uplink list, and the uplink list can be shown in the following table 1:
| unique identifier | House source information | Hash value | Details of the contract | Illegal contents |
| XXXX | XXXX | XXXX | XXXX | XXXX |
TABLE 1
A lessor may provide house source information through either of the house renting nodes 1 or 2. The house information input interface can be preset in the house viewing interface, and when the lessor provides the house information, the house information can be provided through the house viewing interface. For example, if a lessor provides a piece of room source information to the room source lease node 1 through the room source information input interface, the room source lease node 1 acquires the room source information, generates a unique identifier, and determines whether the room source information is a unique room source.
As shown in fig. 6, the property leasing node 1 compares the unique identifier with all the unique identifiers in the uplink list, determines whether the uplink list contains the unique identifier, and when the uplink list does not have the unique identifier, the property leasing node 1 links the property information, records the property information and the like into the uplink list, broadcasts the property information to other nodes, and the other nodes synchronously update the property information. When the unique identifier is contained in the uplink list, whether the house source information is the same as the house source information corresponding to the unique identifier in the uplink list is continuously judged, if so, the house source information is defined as repeated house source information, the uplink is not performed, and a prompt that the repeated house source is not uplink can be fed back to a lessor through a house source information input interface. If the house source information is different, the house source information is defined as the house source information on the update chain, after the house source block is generated by the house property leasing node 1 to be uplink, the house source information and the like are recorded in the uplink list and broadcast to other nodes, and the other nodes synchronously update the house source information.
A tenant can view all the up-linked house source information without illegal contents in the blockchain system through a house source viewing interface of the house rental node 1 or the house source rental node 2.
