Description
Technical field
The present invention relates to electronic contract field, in particular to a kind of electronic contract management method based on block chain and it is
System.
Background technique
Electronic contract is also known as electronic business contract, can define are as follows: electronic contract is between both sides or multi-party party
The agreement for setting up, changing, terminating property civil rights and obligations relationship reached as electrons by electronic information network.
Traditional electronic contract includes EDI, E-mail, and management generally requires to rely on third-party server, data center etc. to complete,
There are the risks of leakage of personal information for electronic contract.For example, being disclosed in the patent document application No. is CN2017114048688
A kind of management method of contract, device, computer storage medium and electronic equipment, by recording the contract information of each user,
Wherein contract information includes room information, cost information, user information and the user caregiver information of user；Receive goal systems
The contract of transmission generates request, and it includes that target user identifies which, which generates request,；From the contract information of each user of record
It searches target user and identifies corresponding target contract information, and according to room information, cost information, the use in target contract information
Family information and user caregiver information generate target contract, target contract are sent to goal systems.That is the contract of the present embodiment
Service unit, to the managing and maintaining of being unified of contract information in endowment community's micro services system, when receiving target system
When the contract that system is sent generates request, target user's mark in request can be based on contract generated, is believed from each contract of preservation
The target user is obtained in breath and identifies corresponding target contract information, and target contract is generated according to the target contract information, into
And time and the network cost of contract generation are reduced, improve the formation efficiency of contract.It follows that itself or a kind of utilization
The system of third-party server completion contract management.
Block chain is a similar open network account book.It originates from bit coin, is the Floor layer Technology of bit coin,
The all information of transaction record can be packaged into one " block " and be stored, with the expansion of information interchange, area one by one
Block is connected with each other, and is formed block chain.It is a kind of point-to-point electronic cash system by the digital cash of representative of bit coin,
Transaction can all broadcast participant all in network every time, and just be recorded in account book after repeatedly confirming,
This account book is exactly " block chain ".Each participant can have the account book of oneself, in this way when deceptive information occurs, so that it may logical
It crosses and mutually verifies to abolish, to guarantee network security.Each node is equality in block chain, and there is no centralizations
Management organization, running do not need anyone intervention, can independently carry out self-authentication.In addition, the network of block chain is to complete
The world is open, anyone can carry out data query, thus whole system highly transparent by open port, in short, block
Chain is a believable database, is one reliable " account book ".
Generally speaking, block chain, Block Chain technology are that occur in recent years in the field financial technology (FinTech)
A kind of emerging technology, unique decentralization, information can not distort, multinode collective maintainability, publicity, secret protection etc.
Attribute can record based in incredible internet and provide believable trading information data.Block chain mainly includes P2P
Network, cryptography, common recognition mechanism, intelligence and about four component parts guarantee that its is exclusive by the technology integration in four fields
Characteristic.However, the management method of the current electronic contract based on block chain lacks effective user credit grade appraisement system.
Therefore, it is necessary to one kind, and center, anti-tamper, highly-safe, credit appraisal system to be gone to improve electronic contract management method
And system.
In view of the above problems of the prior art, the application uses following technical scheme.
Summary of the invention
In order to solve the above technical problems, the present invention provides a kind of electronic contract management method and system based on block chain.
