The example of the consistent device and method of some aspects be described in detail in attached claims, this specification.
It is only to be not intended to be limiting this explanation merely for for the purpose of describing particular embodiments in the term that this specification uses
Book.The "an" of used singular, " described " and "the" are also intended to packet in this specification and in the appended claims
Most forms are included, unless the context clearly indicates other meaning.It is also understood that term "and/or" used herein is
Refer to and includes that one or more associated any or all of project listed may combine.
It will be appreciated that though various information may be described using term first, second, third, etc. in this specification, but
These information should not necessarily be limited by these terms.These terms are only used to for same type of information being distinguished from each other out.For example, not taking off

For the first information.Depending on context, word as used in this " if " can be construed to " ... when " or
" when ... " or " in response to determination ".
The intelligent contract checkschema that this specification provides can be applied in non-area in addition to that can apply in block chain
In block chain.
For applying in block chain, intelligent contract (Smart contract) is that one kind is intended to apply and can be deployed in
The computer protocol that contract is propagated, verified or executed in a manner of information-based on block chain.By stating industry in intelligent contract
Business logic may be implemented to execute corresponding operating.Intelligent contract permission carries out credible transaction in no third-party situation.These
It trades traceable and irreversible.Intelligent contract is capable of providing the safety better than traditional contracts method, and reduces related to contract
Other transaction costs.
Firstly, introducing the deployment way of intelligent contract in traditional block chain.Traditional intelligence contract is directly to be deployed in block
In chain interior joint equipment, and when node device executes transaction request, the corresponding intelligent contract of local disposition is directly run；And
Node device is also stored with the transaction data of full dose.In order to avoid individual node equipment is done evil such as altered data；Such as Fig. 1 a institute
Show, the intelligent contract checking procedure of traditional block chain are as follows:
1. block catenary system can send transaction to multiple node devices.
2. the pre-execution that each node device is traded, and the result set of pre-execution is returned (usually also with corresponding section
The signature of point device).
3. pair each result set verifies, if each pre-execution result is consistent, it is determined that verification passes through.
4. pre-execution result is broadcast to the whole network and is known together (verification for carrying out data mode) after verification passes through.
As it can be seen that needing multiple node devices to repeat pre-execution intelligence contract in existing intelligence contract verification, and pre- every time
Execution all may need the world state for accessing block chain to obtain corresponding data mode, and frequently accessing data mode can consume
Many resources, and efficiency is lower.
This description presents a kind of intelligent contract checkschema based on block chain, is divided into contract administration system for block chain
System and data-storage system, the intelligent contract of the contract administration system only memory block chain, the data-storage system are only deposited
The data mode of storage area block chain.
By reading and writing collection caused by an intelligent contract node pre-execution Intelligent target contract, so that other intelligence contracts
Node, according to memory node, can simulate performance objective intelligence contract using read-write collection without access number again；If it is described its
The simulation implementing result that its intelligent contract node returns is consistent with pre-execution result before, then can determine that verification passes through.Such as
This, on the one hand, the safety that intelligent contract executes can be promoted by logic verify, single intelligent contract node is avoided to do evil.
On the other hand, the intelligent contract node of logic verify is carried out without obtaining data mode again, reduces access data storage section
The number of point.In another aspect, contract verification and data check decoupling in process of exchange are divided into independent two parts；It closes
Node device about in management system is only responsible for contract logic verify, and the node device in data-storage system is only responsible for data school
It tests；It simplifies verification and executes logic, the reduction verification cycle of operation.
The block chain described in this specification can specifically include privately owned chain, shared chain and alliance's chain etc., in this theory
Without being particularly limited in bright book.Node device in the block chain unconfined can add, and each node device can be with
A synchronous system time, to ensure the timeliness of intelligent contract execution.
It should be noted that transaction (Transact ion) described in this specification, refers to through block chain
Client creation, and a data for needing finally to be distributed in the data-storage system of block chain.
Usually there is point of the transaction of narrow sense and the transaction of broad sense in the transaction in block chain.The transaction of narrow sense refers to use
The value Transfer that family is issued to block chain；For example, transaction can be user and exist in traditional bit coin block chain network
One initiated in block chain transfers accounts.And the transaction of broad sense refers to the industry being intended to business that user issues to block chain
Business data；For example, operator can build alliance's chain based on actual business demand, rely on the deployment of alliance's chain it is some with
Unrelated other types of in line service (for example, wide in range can be divided into inquiry business, calling business etc.) of value Transfer, and
In this kind of alliance's chain, transaction can be the service message or business with business intention that user issues in alliance's chain
Request.
Above-mentioned client may include any type of underlying services data stored using in block chain as data branch
Support, to realize the upper layer application of specific business function.
The pre-execution described in this specification can refer to and run intelligent contract without the mistake that is recorded to operation result
A kind of journey, it can be understood as logic execution.One complete volume implementation procedure, including intelligent contract executes and implementing result
Record；But pre-execution is only that intelligent contract executes.
Fig. 1 b is please referred to, Fig. 1 b is the configuration diagram for the block catenary system that this specification provides:
The block chain is divided into contract administration system 11 and data-storage system 12, and the contract administration system 12 stores intelligence
Energy contract, the 12 storage service data of data-storage system.
Include the equipment of several intelligent contract nodes in the contract administration system 11, is wrapped in the data-storage system 12
Equipment containing several data memory nodes.
By linking SDK13 connection between the contract administration system 11 and data-storage system 12, to complete data friendship
Mutually.
Specifically, the contract administration system 11 can be a set of independent block catenary system, be mainly responsible for intelligent contract
Deployment (creation), upgrading (updates) and operation.Also, the contract administration system 11 also needs the execution to intelligent contract
Carry out logic verify.
The data-storage system 12 can be the another set of independent block catenary system for being different from contract administration system 11,
It is mainly responsible for the corresponding data mode of the intelligent contract of storage and change.Also, the data-storage system 12 also needs logarithm
Data check is carried out according to Status Change.
Referring to FIG. 2, Fig. 2 is the stream for the intelligent contract method of calibration based on block chain that one embodiment of this specification provides
Cheng Tu.As shown in Figure 1 b, which can be divided into contract administration system and data-storage system.

Node 1.
2. the transaction is broadcast to the intelligent contract node of any one in contract administration system by data memory node 1；It is set as
Intelligent contract node 1.
Specifically, transaction can be broadcast to any one in contract administration system by data memory node 1 by linking SDK
A intelligence contract node.
3. returning to the result set of signature after intelligent 1 pre-execution intelligence contract of contract node.
Intelligent contract node 1 responds the transaction after the transaction for receiving the broadcast of data memory node 1, can be with prerun
The corresponding Intelligent target contract of the transaction；And by the read-write collection generated during pre-execution Intelligent target contract and other letters
Breath is packaged as result set；Then it signs to the result set, to endorse to result set.Similarly, the intelligence contract section
Point 1 is also the result set for returning to signature to data memory node 1 by linking SDK.
4. the result set that intelligent contract node 1 returns is sent to other intelligent contract nodes by data memory node 1.
Data memory node 1 can also pass through the result set after receiving intelligent contract node 1 and returning the result collection
Linking SDK is sent to other intelligent contract nodes in addition to intelligent contract node 1.
5. other intelligence contract nodes carry out logic verify to result set；If verification is by adding itself in result set
It signs and returns to data memory node 1.
The logic verify includes: that simulation executes intelligent contract, to obtain simulation read-write collection；Whether judge simulation read-write collection
It is consistent with the read-write collection in result set.If consistent, verification passes through；If inconsistent, verification does not pass through.
6. the result set that data memory node 1 returns to other intelligent contract nodes carries out validity check.
Here validity check, which can refer to, verifies the signature of result set, if containing all other intelligence
The signature of contract node, it may be considered that validity check passes through.
7. data memory node 1 occurs to be total to other data memory nodes after validity check passes through, by transaction
Know.
Demonstrate result set it is effective after, can be concentrated from read-write and extract data mode result of variations, and by the number
Other data memory nodes are sent to according to state change result to know together.
8. data storage section carries out data check to data state change；If verification passes through, corresponding data mode is modified,
And transaction is set for effectively transaction.
Here common recognition mechanism mainly carries out data check to data state change；If the data mode changes and this
The data mode of ground storage unanimously then illustrates that verification passes through.To modify corresponding data mode, and transaction is set effectively to hand over
Easily.
9. data memory node 1 returns to prompt information after common recognition passes through.
After common recognition passes through, data memory node 1 can return to prompt information, such as implementing result or generation to user
Block event.Such one complete transaction flow terminates.
Below in conjunction with example shown in Fig. 3, the stream that intelligent contract node 1 obtains data mode to data memory node 1 is introduced
Cheng Tu.
1. data memory node 1 is sent to intelligent contract node 1 by linking SDK and is traded.
Wherein, execution parameter is carried in the transaction.The execution parameter can specifically include contract parameter and business
Parameter.
The contract parameter can be used for positioning Intelligent target contract.The contract parameter may include Contract ID, adjust
With information such as function name, contract version number, input parameter, transaction id, timestamps.
2. intelligent 1 response transaction of contract node executes the corresponding intelligent contract of the transaction；Executing intelligent contract process
In, data mode is obtained to data memory node 1.
Intelligent contract node 1 based in the contract parameter Contract ID, call the information such as function name, can determine tune
With function interface method.
Data mode needed for the service parameter can be used for positioning execution contract logic.
The difference of service parameter illustrated below and data mode:
Assuming that the transaction that client is sent is to enable a+1.Then field a and plus 1 be service parameter, and a current value is
Data mode.In actual operation a+1, it is necessary first to obtain the original value (business datum) of a, then add on the basis of original value
1 can just obtain implementing result.
As shown in figure 3, intelligent contract node 1 can produce read-write collection (r/w set) in executing contract logical process.
The read-write collection may include Contract ID, state is read and state write-in.
Here which intelligent contract Contract ID is for indicating that read-write collects corresponding.Here state reading refers to intelligence
Energy contract node 1 accesses data memory node 1 by linking SDK to the data mode of reading.Here state write-in refers to
According to the calculated changed data state of the data mode read.
Typically for complicated intelligent contract, is read there are multiple groups state and state is written；That is read-write collection can be closed intelligently
The data acquisition system that all states are read about in implementation procedure and state write-in is constituted.It can really reflect intelligence by reading and writing collection
The entire execution calculating process of contract.
3. implementing result can be returned to data memory node 1 after intelligent contract node 1 has executed intelligent contract.
Here implementing result can be to collect result set made of packing for contract parameter, read-write, and is the result
Collection carries out signature endorsement.
This specification embodiment can be applied in traditional block other than applying the block catenary system shown in above-mentioned Fig. 1 b
In catenary system, as shown in Figure 4:
1. Client-initiated transaction is sent to any one node device by block catenary system.
