Block catenary system is a kind of system based on block chain technology, and also referred to as distributed account book technology is a kind of mutual
Networking data library technology.Its main feature is that it is decentralization, open and clear, allow each user to each may participate in maintenance data-base recording.Area
Block catenary system mainly includes network layer, common recognition layer and data Layer etc..Block catenary system is Distributed Storage, point-to-point biography
The new application mode of the computer technologies such as defeated, common recognition mechanism, Encryption Algorithm.Wherein, data Layer encapsulates bottom data block
And the basic datas such as relevant data encryption and timestamp and rudimentary algorithm, and bottom data block is presented with chain structure,
I.e. block chain is a kind of a kind of linked data structure for being sequentially in time combined into data block in such a way that sequence is connected,
And the distributed account book that can not be distorted He can not forge guaranteed in a manner of cryptography.
Therefore this step is able to achieve the distributed recording and distributed storage of information of real estate using block chain technology, and so-called point
Cloth record is exactly that can be set as in block catenary system by any house lease system for recording information of renting a house in house property medium
A certain node, the node be house lease node, record information of real estate, generate source of houses block and in block catenary system on
Chain, information of real estate rather than recorded by the mechanism of a centralization, so-called distributed storage is that data can store all
In the node for participating in maintenance data, rather than it is centrally stored in the agency node of centralization.
All nodes all preset cochain list in the database in block catenary system, and cochain list includes all areas
The corresponding unique identification of block chain, information of real estate and cryptographic Hash, after house lease node completes cochain, by the source of houses block pair of cochain
Unique identification, information of real estate and the cryptographic Hash answered are recorded in cochain list.
Information of real estate may include source of houses details and status information in this step, and source of houses details include source of houses address, hire out
People's information, floor space and rent, status information include that can hire out, hire out, not allowing to hire out three kinds of states.
Unique identification can be house and land property card number or real estate warrant number, can also be source of houses address or pass through coding
The unique encodings that generator generates, as long as the uniqueness of information of real estate can be determined.
Cryptographic Hash is to be located at the cryptographic Hash of the last one block in chain in the corresponding block chain of a certain information of real estate.
Source of houses block is stored in block catenary system by the upper chain process by source of houses block in block catenary system when cochain
Data Layer in process.
Step S2, information of real estate are shown: house lease node is by informations of real estate all in cochain list in preset room
Source is checked in interface and is shown.
In order to check information of real estate for tenant, the source of houses is preset in each house lease node and checks interface, is passed through
The source of houses checks all informations of real estate of this house lease node of showing interface storage.And tenant sees room, the negotiation with lessor
Process etc. under house property medium side's line of this house lease node by carrying out.It is handed over when tenant and lessor reach house lease
Yi Shi is carried out in next step.
Step S3, contract cochain of renting a house: house lease node is received containing lessor, tenant and party intermediary electronic signature
House-leasing contract, include unique identification in house-leasing contract, house lease node is by house-leasing contract and unique
Identify corresponding information of real estate and generate contractual block, by contractual block in block catenary system cochain, and pass through block catenary system
Chain structure, contractual block is linked to the corresponding cryptographic Hash of unique identification, forms new block chain, house lease node will
House-leasing contract is recorded in cochain list.
It can be preset with house-leasing contract receiving interface in house lease node, can also be checked in interface in the source of houses
A certain information of real estate interface adds house-leasing contract and uploads interface, can also preset the electronic signature system of house-leasing contract
System, so that lessor, tenant and party intermediary sign to house-leasing contract.
It also include contract details in this step in house-leasing contract in addition to including unique identification, contract details include
Lessor's information, lessee information, party intermediary information, floor space, rent, payment method, payment record and time limit.
Traditional house lease process is recorded information of real estate and contract letter by the node of block catenary system by the present embodiment
Breath, and information of real estate is unique, lessor hangs more without a room, and tenant finds the source of houses without finding multiple party intermediaries, as long as
All nodes in block catenary system can view information of real estate.Since the information of house lease node is consistent, intermediary
Side is become comparing with service from competition information, improves the service quality in house lease market.
In one embodiment, also that the source of houses block or contractual block of cochain is wide after the completion of house lease node cochain
It broadcasts to other nodes in block catenary system, after other nodes receive broadcast, by the corresponding information of real estate of source of houses block and Kazakhstan
Uncommon value is updated in the list of cochain of respective node, and the corresponding house-leasing contract of contractual block is recorded respectively other nodes
From in the list of cochain of node.
All nodes in block catenary system are all preset with cochain list, and the list of cochain of each node should be same
Step, i.e., information of real estate is consistent.Therefore also the block of cochain is broadcasted after a certain node completes cochain, other nodes receive
To after broadcast, update or record are synchronized to the list of cochain in respective node.The present embodiment is as long as long as a certain node
It can check all informations of real estate in all block catenary systems, and information of real estate is newest information.
In one embodiment, in step S1, unique identification and information of real estate is generated into source of houses block, source of houses block is existed
In block catenary system before cochain, as shown in Fig. 2, whether house lease node is also that unique source of houses judges to information of real estate:
Step S101, compare unique identification: house lease node is the institute in the unique identification and cochain list of generation
There is unique identification to be compared, when not having unique identification in cochain list, house lease node is by unique identification and the source of houses
Information generate source of houses block, by source of houses block in block catenary system cochain, cause generate information of real estate a block chain, and
The corresponding unique identification of source of houses block, information of real estate and the cryptographic Hash of cochain are recorded in cochain list.
All unique identifications recorded in cochain list are all the informations of real estate of cochain, in order to guarantee house lease
Node will cochain information of real estate uniqueness, avoid the problem that the multiple cochain of same information of real estate, this step is by by room
It produces the unique identification that lease node generates to be compared with all unique identifications in cochain list, judges whether it is cochain
Information of real estate, when there is no unique identification in cochain list, it is believed that this information of real estate is not also by cochain, house lease node
Continue to generate source of houses block and cochain work.After the completion of cochain, for the synchronization and uniformly of data, house lease node is also
The corresponding unique identification of source of houses block, information of real estate and the cryptographic Hash of rigid cochain are recorded in cochain list.
Step S102, judges information of real estate: when containing unique identification in cochain list, continue judge information of real estate and
Whether the corresponding information of real estate of unique identification identical in cochain list, such as it is identical, then house lease node to information of real estate not
Carry out cochain.
When containing unique identification in cochain list, it is believed that this information of real estate cochain, at this point, also continuing judging cochain
The information of real estate that provides of the lessor that obtains of information of real estate and house lease node it is whether identical, it is such as identical, then it represents that be phase
Same information of real estate, in order to avoid repeating cochain, house lease node is to information of real estate without cochain.
Step S103, cochain: as different, then unique identification and information of real estate are generated source of houses block by house lease node,
By source of houses block, source of houses block is linked to the source of houses and by the chain structure of block catenary system by cochain in block catenary system
The corresponding cryptographic Hash of information forms new block chain, and information of real estate and cryptographic Hash is updated in cochain list.
In the information of real estate difference that the lessor that the information of real estate and house lease node that judge cochain obtain provides, recognize
There is the case where updating information of real estate for lessor, this information of real estate is not to repeat cochain, but should connect more new information
Onto the block chain of cochain, house lease node continues to generate source of houses block and cochain work at this time.After the completion of cochain,
For the synchronization and uniformly of data, house lease node also by the corresponding information of real estate of source of houses block and cryptographic Hash of rigid cochain more
Newly into cochain list.
The present embodiment in order to determination will cochain information of real estate uniqueness, unique identification and information of real estate are compared
To judgement, guarantee the uniqueness of the information of real estate of cochain, so that newest unique source of houses can be checked by realizing on any node, avoids
One room hangs phenomenon more.
It in one embodiment, include status information in information of real estate, status information includes that can hire out, hired out or not permit
Perhaps three kinds of states are hired out status information is arranged before unique identification and information of real estate are generated source of houses block by house lease node
For state can be hired out, and information of real estate is updated in cochain list, house lease node is by house-leasing contract and uniquely
Before identifying corresponding information of real estate generation contractual block, the state of having hired out is set by status information, and information of real estate is updated
Into cochain list.
The status information of the present embodiment can clearly state the case where information of real estate, and tenant can pass through status information
The status for understanding the information of real estate, when the subsequent source of houses checks showing interface information of real estate, status information is also used as selecting
When item is checked for tenant, information of real estate is screened, such as checked in interface in the source of houses and just look at the room that can hire out state
Source information.
In one embodiment, as shown in figure 3, the payment of hire process between tenant and lessor can use it is as follows
Step:
Step S401, payment or rent: financial service node receives the payment request that tenant initiates, and includes in payment request
There are lessor's fund account, rent and unique identification, financial service node provides payment of hire to lessor according to payment request
Golden account.
In block catenary system, it will realize that any financial services system of payment function is set as block chain in financial institution
One node of system, the node are financial service node.It is public that financial services system can be insurance company, bank or loan
Department etc. provides the system of financial service.Financial service node participates in block catenary system, checks the source of houses in block catenary system
Information etc. puts up cash for lessor and flows the service such as loan.Financial service node can also look at the payment of house-leasing contract
Mode and payment record are supplied to the follow-up services such as tenant's credit card.Financial service node is tenant and goes out in this step
Rent people's cash call stream service.
Step S402, payment record cochain: financial service node is corresponding to unique identification by the content record of payment request
House-leasing contract payment record in, the house-leasing contract containing payment record and information of real estate are generated into payment area
Block will pay block cochain in block catenary system, and pass through the chain structure of block catenary system, and payment block is linked to only
The corresponding cryptographic Hash of one mark, forms new block chain.
All nodes in block catenary system are preset with cochain list, and the list of cochain of each node should be same
Step, i.e., information of real estate is consistent.Financial service node is also the node in block catenary system, therefore also presets in financial service node
Cochain list.It include the information of real estate, unique identification, cryptographic Hash, house lease of all cochains in cochain list
Contract etc..Financial service node first passes through unique identification and obtains corresponding house rent in the cochain list of this node before cochain
It rents contract, by the payment record of the content record of payment request to house-leasing contract, then by house-leasing contract and room
Source information generates payment block and cochain, checks specific payment record for other nodes in block catenary system.
Broadcast payment block: the payment block of cochain after the completion of financial service node cochain, is also broadcast to by step S403
Other nodes in block catenary system, other nodes arrange the cochain that payment record is updated to respective node after receiving broadcast
In table.
By way of broadcast, other nodes in block catenary system can be by payment record synchronized update to respective node
In cochain list.
The present embodiment will realize that any financial services system of payment function is set as block catenary system in financial institution
Financial service node can have several financial service nodes in block catenary system, and tenant can choose any financial service section
Point completes payment of hire, and lessor can choose any financial service section and fulfil fund, and entire payment of hire process is transparent.Finance
Service node can provide subsequent financial service according to payment of hire situation for tenant.Government organs can also pass through block
Catenary system is supervised, and responsibility is defined.
In one embodiment, as shown in figure 4, the process of supervision of government organs can use following steps:
Step S501, supervisory node show information of real estate: supervisory node is to informations of real estate all in this node preset
The source of houses is checked in interface and is shown.
In block catenary system, a node in block catenary system is set by supervisory systems any in government regulation,
The node is supervisory node.Supervisory node is also preset with cochain list.It include the room of all cochains in cochain list
Source information, unique identification, cryptographic Hash, house-leasing contract etc..Supervisory node opens up the information of real estate in cochain list
Show, provides supervision data for supervisor.
Step S502, violation content cochain: supervisory node receives the source of houses violation information that supervisor sends, and the source of houses is in violation of rules and regulations
Information includes violation content and unique identification, and the status modifier in the corresponding information of real estate of unique identification is not permit by supervisory node
Perhaps state is hired out, violation content, unique identification and information of real estate are generated supervision block by supervisory node, by supervision block in block
Cochain in catenary system, and pass through the chain structure of block catenary system, by unique mark in controlled area block chaining to cochain list
Know corresponding cryptographic Hash, forms new block chain.
Check that a certain information of real estate interface at interface can add source of houses violation information input word in the source of houses of supervisory node
Section uploads interface.It, can be directly to this information of real estate when supervisor checks that a certain information of real estate is checked at interface by the source of houses
Record violation content.Supervisory node has the permission for forbidding a certain information of real estate to hire out, and permission specific manifestation is in information of real estate
Status information in, when status information is revised as not allowing taxi state, definition thus information of real estate in violation of rules and regulations, answer offline.Cause
After this supervisory node receives source of houses violation information, modification status information and cochain are looked into for other nodes in block catenary system
It sees.
Broadcast supervision block: the supervision block of cochain after the completion of supervisory node cochain, is also broadcast to block by step S503
Information of real estate is updated to the cochain list of respective node after receiving broadcast by other nodes in catenary system, other nodes
In, it will be in the list of cochain of violation content record to respective node.
By way of broadcast, other nodes in block catenary system can update violation content synchronization to respective node
In cochain list.
Supervisory systems any in government regulation is set the supervisory node in block catenary system, block linkwork by the present embodiment
Can have several supervisory nodes in system, supervisory node checks information of real estate by block catenary system, can also to information of real estate into
Row subsequent statistical increases violation content, realizes and facilitate the purpose that supervision is rented a house in real time for not being inconsistent information of real estate normally.
Include government regulation in block catenary system, more can guarantee lessor and tenant's common interest.
In one embodiment, after when house lease nodes records to the information of real estate containing violation content, house lease
The source of houses is checked that the progress of the information of real estate in interface containing violation content is offline by node, and house lease node will be in cochain list
Information of real estate without containing violation content is checked in interface in the source of houses to be shown.
Information of real estate containing violation content is defined as that process of renting a house can not be carried out, therefore house lease node is looked into the source of houses
The information of real estate that violation content is free from shown in interface is seen, so that tenant checks.And the source of houses containing violation content
Information is checked offline in interface from the source of houses.
The present embodiment embodies the supervision achievement after government participates in block catenary system, and the violation source of houses is realized from rent
The source of houses head when that is, tenant checks information of real estate, is forbidden checking, the possibility for avoiding the violation source of houses from being leased.
