Specific embodiment
In order that the technical problems to be solved by the invention, technical scheme and beneficial effect become more apparent, below tie
Drawings and Examples are closed, the present invention will be described in detail.It should be noted that specific embodiment described herein is only used
To explain the present invention, it is not intended to limit the present invention, can realizes that the product of said function belongs to equivalent and improvement, includes
Within protection scope of the present invention.Specific method is as follows：
Embodiment 1：In block catenary system, the execution step of general contract is as follows:
1. contract details is all agreed to by each side for participating in contract；
2. the details of contract is decided through consultation and reached an agreement；
3. transaction is shared after execution date, between contract side；
4. completion is performed.
If cannot reach an agreement between contract side, then the payment of transaction cannot be completed.Accordingly, it would be desirable to arbitrator is closing
About mediated between side.Arbitrator is often third party trusty, such as NGO, arbitration court.Arbitrator needs
Complete following behavior：
1. arbitrator is checked the content of contract；
2. the data that pair contract side gives is examined；
3. the result of pair contract is determined；
4. force contract side to be performed by the content of contract.
The execution of contract depends on the reliability of contract side, and arbitrator can force contract side to perform.The execution of contract can consume
Take extra fund and energy, also, need to meet having among these at 2 points：The each side of contract will trust each other, to arbitration
Person accomplishes to trust immediately.
Therefore, contract side is required for trusting each other and accomplishing to trust immediately.For contract, the selection of arbitrator
And the execution of contract has certain difficulty, has following conflict situations should be noted：
1. the judgement system for being used for contract judgement may have hysteresis quality；
2. judgement system may be destroyed；
3. in the implementation procedure of contract, may be disturbed by other each contract sides or external factor.
Contract side may come from each different country, relatively more difficult to reach contract, accomplish that contract side trusts very immediately
Difficulty, and the high cost trusted immediately, or even can be higher than the profit of contract, the cost for solving contract conflict is also very high.
Intelligent contract has following unique advantage mainly for the trust problem immediately of contract：
1. it is reliable that contract is performed；
2. contract can be carried out between phase mutual mistrust between each contract side；
3. the arbitrator that need not be trusted；
4. the block chain account book in quantum catenary system is automatically carried out, it is not necessary to the participation of personnel.
The execution logic of intelligent contract is as follows：
1. contract side needs definition standard intelligence contract in advance or creates a new intelligent contract；
2. intelligent contract is permanently stored in the block chain of quantum catenary system, it is impossible to changed by any each side；
3. concluded the business for each side that intelligent contract is provided with funds directly can send to intelligent contract；
4. when arriving at the moment for performing, intelligent contract is by freezing of funds；
5. after execution date, intelligent contract is automatically for fund is shared by the contract side for participating in.
In the implementation procedure of whole intelligence contract, without trusting between contract side, any each side can participate in intelligence
Contract.The crypto module of all responsible quantum catenary system in contract side, and give and trust, without the arbitrator for trusting.Intelligence is closed
Specific execution about is as shown in Figure 2.
Intelligent contract solves the problems, such as law suitable for the transaction of various countries.Legal issue comprising boundary it is not clear, the 3rd
Conflict of laws and the solution cost of side's intervention are, it is necessary to the negotiation and the compromise of each side of complexity.The running cost of transaction can be in intelligence
Can automatically be deducted in contract.
Embodiment 2：
The execution of intelligent contract generally requires the input of definition transaction in advance and the output of transaction.When transaction recipient with
The quantity of transaction is determined, and the recipient of transaction can be instantly available their deserved money.Intelligent contract once changes, transaction
Recipient cannot determine with quantity.When being arrived between upon execution, intelligent contract can make due judgement.
When the output of transaction is uncertain, the relation of time shaft is there is from the execution for being created to transaction of transaction, handed over
Between easy creation time and the execution time of transaction, intelligent contract is created, after reaching transaction execution time, intelligent contract is made
It is corresponding to determine, output is determined, as shown in Figure 3.
The type of transaction of intelligent contract mainly has two kinds：Intelligent contract starting transaction and intelligent contract funds transaction.Intelligence
The parameter for being used for concluding the business can be included in contract.Intelligent contract starting transaction is first participant of intelligent contract.When intelligent conjunction
All participants about have started to conclude the business and there is funds transaction with intelligent contract, and transaction starts.In transaction execution
Before time arrives, all funds are frozen all in transaction, are no longer used by anyone.When the implementing result of intelligent contract
After out, all participants can just obtain fund.Intelligent contract is provided with automaticity, it is not necessary to the participation of personnel.Intelligent contract
For each side of All Activity provides variable, flexible fund sharing mechanism.The output of transaction only starts in intelligent contract
Just start afterwards.
The data that intelligent contract is finally received are possibly used for the decision that last fund is shared.Intelligent contract can be as all
The information of block chain, transaction, account, the entrance of assets.
When needing to obtain information from the external world, it is necessary to Oracles.The supplier of Oracles is to write-in letter in Oracles
Breath, intelligent contract can be write by Oracles vector sub-block chain account books.Oracles is embedded in block chain account book, can be fast
It is read fastly.The supplier of Oracles can be tissue or personal, and function is to write data in block chain.Write-in data
Form be JSON forms, write data during, quantum catenary system can carry out the inspection of correctness and security to data
Look into, only to the data of intelligent contract supply security.
The block chain network of Quantum Chain is a network system being made up of node.Intelligence can be set up in network system
Contract.Intelligent contract is only recognized by most of nodes, could be recognized.One side of the win of only intelligent contract determines how to spend
Take fund.
Intelligent contract must have predictive behavior, if being not previously predicted behavior, then intelligent contract will randomly determine to pay
The object of money.When intelligent contract determines how the distribution of fund, cannot just change the decision of the distribution.
Intelligent contract must have the presence that the basic reason of predictability is common recognition process.Intelligent contract will know together
Be used to calculate in journey, propagated in the node of each decentralization, be performed fully, dependent/non-dependent.In common recognition process
The execution of middle intelligent contract, different time might have difference.But implementing result at any time, any node be all identical
's.For intelligent contract, available constraint is there is in input data and functionally.For intelligent contract, each
Node and function have clearly logical relation.In initialization, intelligent contract can be defined to the output concluded the business.
The input of transaction is as shown in Figure 4 with the value transmittance process of the output of transaction.If last defined in the initialization of intelligent contract
The execution time, oracles need not provide necessary data.If to the last execution time, intelligent contract still cannot
With, then fund must be returned to each side for participating in intelligent contract.
The preferred embodiments of the invention is the foregoing is only, claims of the invention are not limited to.
Simultaneously it is described above, for those skilled in the technology concerned it would be appreciated that and implement, therefore other be based on institute of the present invention
The equivalent change that disclosure is completed, should be included in the covering scope of the claims.
Useful achievement of the invention is：The advantage of the intelligent contract type implementation of quantum catenary system of the invention is：
The execution reliability of intelligent contract is high；Even if contract side distrusts each other, it is also possible to carry out the transaction of intelligent contract；It is not required to
Arbitrator is wanted to be mediated between contract side；Block chain account book in quantum catenary system can be automatically carried out, it is not necessary to volume
The participation of outer personnel.
