It is shown, this method comprises:
Step 101, the first user participation node knows second user to the discreditable behavior of the first user, and generate and break one's promise row
For corresponding record of breaking one's promise, wherein record of breaking one's promise includes: the first of contract information, promise breaking information and carrying time limit first time
It assures information, and is broadcast in block chain network after carrying out the first private key signature to record of breaking one's promise.
Wherein, it is the equipment corresponding to the first user in block chain network that the first user, which participates in node, can be intelligence
Terminal, laptop etc..
In addition, second user includes the first user when trading with second user to the discreditable behavior of the first user,
A variety of behaviors without the transaction of Information fulfillment as agreed, for example, not according to agreement repayment date or repayment amount refund credit
The behavior of card, for example, not paying up the behavior etc. of telephone charge, water rate or gas charge, rent etc. according to the time limit.
In the present embodiment, when the first user is not with second user Information fulfillment trading activity as agreed, then really
Determining second user has discreditable behavior to the first user, thus, the first user participates in node and knows second user to the first user
With discreditable behavior, in order to enable the node in block chain knows the discreditable behavior, in order to second user participate in node into
The judgement of row credit, broadcasts the discreditable behavior in block chain network, and specifically, the first user participates in node generation and discreditable behavior
Corresponding record of breaking one's promise, wherein include the first of contract information, promise breaking information and carrying time limit first time in the record of breaking one's promise
Assure information.
Wherein, above-mentioned promise breaking information is corresponding with contract information, is used to indicate the specific violation of agreement of second user, in order to
The interdependent node for receiving record of breaking one's promise determines the credit grade etc. of second user based on the contract information and promise breaking information.Separately
Outside, above-mentioned underlying mortgage information includes security cost etc., to send record of breaking one's promise for constraining the first user participation node
Authenticity, when the first user participate in node send break one's promise be recorded as false record when, need to pay corresponding Guarantee fee
With etc., wherein underlying mortgage information can be based on Rulemaking pre-set in block chain network, be also possible to by
One user participates in node and makes setting by oneself, wherein needing to meet greater than block chain when the first user participates in node sets itself
Pre-set minimum guarantee information standard in network.
In an embodiment of the present invention, underlying mortgage information carries time limit first time, which is used for
It limits to complaint time of record of breaking one's promise, in time limit first time, second user can be appealed, not to second user
Record of breaking one's promise carries out generation blocks operation, likewise, time limit first time can be by based on pre-set in block chain network
Rulemaking, it is also possible to make setting by oneself by the first user participation node, is voluntarily set wherein participating in node in the first user
Periodically, it needs to meet and is greater than pre-set minimum time standard in block chain network, that is to say, that in time limit first time
It is interior, it can be ensured that first participating user's node can receive realization and record and complete to appeal.
In turn, in the present embodiment, the identity for participating in node for the first user based on the first public key and the first private key is recognized
Card, the first private key oneself are held by participation node, and the first public key is sent to block chain network in the form broadcasted, so that with first
Corresponding relationship of the interdependent node based on the first public key and the first private key that user participates in node communication participates in node to the first user
Carry out authentication.It is broadcast in block chain network after carrying out the first private key signature to record of breaking one's promise.

Freezed with the security cost of node last time by the corresponding management platform of block chain network.
The deduction of corresponding security cost is finally carried out according to complaint result, if knowing second user pair according to complaint result
There are discreditable behaviors by first user, then the security cost for deducting B last time participates in node to the first user and compensates, and
Certain credit payment expense is paid for block chain network, if knowing that second user does not deposit the first user according to complaint result
In discreditable behavior, then the security cost for deducting A last time participates in node B to second user and compensates, and is block chain
The certain credit payment expense of network payment, and retract the security cost of B.
Certainly, in practical implementation, security cost is raised by malice in order to avoid user participates in node, so that right
Square user participate in node can not the higher security cost of Zhi Fuqi and credit complaint can not be carried out, point at any time, node A and
B can conciliate or request the progress ruling of third party authoritative institution under line, and ruling result or reconciliation result are sent to block
Chain network, so that last security cost and ruling result or reconciliation result of the block chain network according to node A and node B
Carry out the processing of security cost.

Card, then generates the first credit accounting information, and be broadcast in block chain network if the verification passes.
Dig mine accounting nodes the first credit Accounting message is recorded in block chain account book, and according to underlying mortgage information from
First user participates in node and obtains corresponding credit payment expense, and later, it is logical that other nodes are that second user participates in node
When letter, you can learn that being rejected by and trading with it if its credit record is bad to its credit record, form as a result,
Credit constrains strength.If user B thinks to break one's promise and records falseness, second user participate in node can previous existence time limit first time at
Corresponding credit complaint message is recorded with breaking one's promise, if winning a lawsuit, it is required that the first user participates in node publication revocation statement, and is given
The certain compensation of user B is given, if lost a lawsuit, user B needs the compensation certain to the user A of platform sum.
