Detailed Description
In order to make the invention more comprehensible, preferred embodiments are described in detail below with reference to the accompanying drawings.
The invention relates to a house leasing system based on a alliance chain architecture, which achieves the effect of safe leasing by introducing authentication nodes and record nodes into an alliance chain organization, authenticating the authenticity of house source and personal identity information and backing up leasing contract information.
The participating nodes of the federation chain are respectively: authentication department node, record management department node, leasing public node. The authentication department node has the functions of authenticating house source information and authenticating personal identity information, the record management department node has the functions of recording a lease contract and registering a leaser, and the lease public node has the functions of contract signing and contract canceling, so that the lease contract can be cancelled within a certain time.
As shown in fig. 3, three intelligent contracts are designed, wherein a tenant calls a red contract, the red contract calls a Record management contract and an Identification contract, and the contract content is as follows:
(1) rent contract function design: and signing lease terms, wherein the terms comprise information contents such as house lease starting and ending dates, house monthly rent fees, overdue daily fees, damaged house fees, relevant provisions and the like.
Rent lease term contract pseudo code design:
Input:personR,personB，tx，house
If reg(personR)and reg(personB)and reg(house)
Write(tx)
Wait time 72h
If(message)withdraw tx
Else return
End if
Output:tx
description of the drawings: personR and personB are respectively a tenant, a landlord, house property, tx is a transaction contract, and message is a withdrawal contract message.
The premise of signing the lease contract is that identity information of both parties of the lease is verified to be correct, house property information verifies that information such as service life is true under the name of a house owner, then both parties reach consensus, house lease terms are signed, and lease behaviors are finished. If the tenant regresses repeatedly within 72 hours, a message can be sent for revocation.
(2) The Identification contract function design: and relevant information contents such as resident identity information authentication, house source authentication and the like.
Identification authentication contract pseudo code design:
Input:person,house
If reg(person)and reg(house))
Person_state＝yes,house_state＝yes
Else Return
End if
Output:person_state,house_state
description of the drawings: person is personal information, house is a property, person _ state and house _ state are corresponding personal information state and property state.
Before the lease contract is signed, the lease contract needs to go through an authentication center to verify information such as personal credit and confirm house property information under name, so as to obtain an authentication result.
(3) Record management contract functional design: recording house information and recording renter information.
RecordManage records contract pseudocode design:
Input:tx,tx_state
Wait time 72h
If(tx.state)
pack(tx)return yes；
Else Return no；
End if
Output:yes/no
description of the drawings: tx is the transaction and tx _ state is the transaction state.
The record management department carries out record management on the achieved lease contract, and the record can be used for handling lease affair disputes and analyzing the lease status of floating population.
As shown in fig. 4, the house leasing method based on the alliance chain architecture of the present invention includes the following steps: the method comprises the steps that a tenant firstly logs in a house leasing system, finds out a proper house source, achieves leasing intention with a house source leasing party, triggers an intelligent contract in the system, achieves the contract after the contract is authenticated by an authentication department, if the tenant has the intention of repenting within 72 hours, the contract can be cancelled, otherwise, after the time limit is passed, a record management department records the related information of the leasing contract, and the whole leasing process is completed.
Wherein the house source renting party is as follows: private landlors, public rental houses, rental companies. The tenant is a house renter, and the authentication department comprises personal identity information authentication, house property authentication and record management department for managing rental records. The renters and house resource renters are collectively called the renting public. The related recorded account book is stored by adopting a block chain, and the rented mass account book is simultaneously managed by an authentication department and a record management department, as shown in figure 5.
When the intelligent contract is triggered, a Rent intelligent contract is triggered at first, a Record management intelligent contract and an Identification intelligent contract are called at the same time, the Identification contract confirms identity information of a tenant and authenticates a house source at the same time, the house source is authenticated under the condition that the house is subordinate to the house owner, the result is returned to the Rent contract after the authentication is completed. And (3) finishing the preliminary house leasing, after 72 hours, carrying out node broadcast Record accounting on the leasing Record by using a Record management contract, finishing the whole leasing process, and if the tenant withdraws the leasing intention, terminating the Record management.
