Specific embodiment
To keep the purposes, technical schemes and advantages of the application clearer, below in conjunction with the application specific embodiment and
Technical scheme is clearly and completely described in corresponding attached drawing.Obviously, described embodiment is only the application one
Section Example, instead of all the embodiments.Based on the embodiment in the application, those of ordinary skill in the art are not doing
Every other embodiment obtained under the premise of creative work out, shall fall in the protection scope of this application.
It, may concurrent large-scale intelligent contract on block chain in the prior art as background technology part is stated
Application, but the characteristic of the intelligent contract on existing block chain is single, is unable to satisfy the demand of different application scene.Such as：
" contract " attribute of some intelligent contracts is very strong, after contract foundation either party without weight update, recall, that is, believe in
" code is law "-code is exactly law；And if the subsequent desired update of contract participant upgrades the contract, will appear can not
The problem of updating upgrading；Also some intelligent contracts are more like traditional building in this distributed operating system of block chain
On application, contract is all to be at will updated upgrading to intelligent contract, but will appear the problem of trusted mechanism is destroyed,
Such as：Contract is all to move the contract gold of participant privately.
It can be seen that being continuously increased with contract scale intelligent on block chain, the intelligent contract of single characteristic is obviously got over
To be more difficult to meet the needs of more application scenarios.
Based on this, the present invention provides a kind of block chain intelligence contract update method, passes through the security level to intelligent contract
It is divided, obtains the security level of multiple and different characteristics, to be adapted with the demand of the different application scene on block chain, with
The prior art is compared, and the exploitation iteration of intelligent contract and the spirit of deployment on the basis of not influencing trusted mechanism, can be effectively improved
Activity.
Application scenarios of the invention are illustrated referring to attached drawing.
Referring to Fig. 1, a kind of application scenarios can be：
It include node 1, node 2 ... node 6 etc. in block chain.Wherein, it is each equipped with update management module on each node,
The update management module is for determining the security level for the intelligent contract being committed on this block chain, to upgrade intelligence for subsequent update
It can contract offer basis.Optionally, the specific number of the node on block chain is not limited herein.
By taking node 1 is the corresponding node of all sides (account) of the first intelligent contract as an example, need in all sides to first
When intelligent contract is updated upgrading, more new information request is submitted into cochain in the form of transaction request by node 1.Then, area
Common recognition node on block chain determines the security level of the first intelligent contract, and then can be based on the corresponding contract characteristic of the security level
Common recognition verifying is carried out to the transaction request, if allowing more new information cochain by common recognition verifying, with to the first intelligent contract into
Row updates upgrading.
Wherein, common recognition verifying refers to ballot by special joint, in a short period of time the verifying of complete swap and
Confirmation.
Below in conjunction with attached drawing, the technical scheme provided by various embodiments of the present application will be described in detail.
Fig. 2 is a kind of flow diagram for block chain intelligence contract update method that one embodiment of this specification provides, ginseng
See Fig. 2, this method can specifically include following steps：
Step 22 receives the first transaction request that the first transaction node is initiated, and first transaction request will for request
The more new information of intelligent contract submits cochain, and first transaction node is the corresponding node of all sides of the intelligent contract；
Wherein, which is the intelligent contract of cochain；More new information be in intelligent contract right, obligation,
The information that the condition etc. of triggering clause is modified, for adding the updates such as clause, deleted clause operation；All sides are with this
The account of intelligent contract permission, can be contract participant, be also possible to the third party of contract participant trustship.
It should be noted that further including before step 22：Intelligent contract cochain step, in conjunction with Fig. 3, the step is specific
Include the following steps：
Step 32 receives the second transaction request that first transaction node is initiated, and second transaction request is for asking
It asks and the intelligent contract is submitted into cochain；
It wherein, include the security level of the intelligent contract in second transaction request, the security level is prewired
The parameter of degree of risk size set, for indicating the corresponding transaction of the intelligent contract, the security level the big, shows to hand over
Easy risk is bigger, it is on the contrary then show when time transaction risk it is smaller；First transaction node is had on the intelligence contract
Signature.
It should be noted that being pre-configured the first implementation of security level step can be：
When contract participant is formulated or uploads intelligent contract, corresponding node provides security level choosing for contract participant
Frame is selected, security level choice box therefrom selects a safety for showing at least one security level, by the negotiation of contract participant
Security level of the rank as the intelligence contract.
Be pre-configured security level step second of implementation can be：
It is the security level of intelligent one default of contract configuration by corresponding node.It specifically can be exemplified as follows：
Example 1, corresponding node scan the keyword in intelligent contract, safety level needed for assessing contract based on keyword
Not；Specifically：
Corresponding node scans intelligent contract and determines amount of money involved therein, participant type (company, unit, colleges and universities, individual
Deng), clause quantity etc. keyword；Intelligent contract is assessed based on keyword, determines its security level that may be needed,
Assessing rule can be：The amount of money is more, and required security level is higher；Clause is more, and required security level is higher；Participant type
Required security level is generally company > unit > > people of colleges and universities；
Example 2, corresponding node determine the contract type of intelligent contract, safety level needed for assessing contract based on contract type
Not；Specifically：
Corresponding node scans intelligent contract header or scans the content of intelligent contract, determines the contract type of intelligence contract；
The corresponding safety level of intelligence contract is selected from the security level that empirical value/expert advice etc. is various contract Specific dispositions
Not.Wherein, the security level of various contract Specific dispositions can be exemplified as：Commercial affairs contract configures highest security level；Life
In common contract (such as：For electricity consumption, water, air and heat power contract etc.) the lower security level of configuration.
Wherein, corresponding node can be the corresponding node of contract participant, or the corresponding node of all sides of contract.
Step 34 know together to second transaction request and test；
It should be noted that a kind of implementation of step 34 can be：
It verifies the signature for whether having designated user on the intelligence contract and whether signature is legal, if so, determining common recognition
Verification result is to pass through；If not, it is determined that common recognition verification result is not pass through；
Wherein, the requirement of participant when designated user depends on the classification of intelligent contract, formulates.
Step 36, common recognition verifying result be by when respond second transaction request.
That is, common recognition verifying result be by when, the second transaction request of response allows intelligent contract cochain, by the intelligence
In energy contract deposit memory node；
As it can be seen that the present embodiment is by the way that before cochain intelligence contract, the demand based on its application scenarios is closed in advance for intelligence
A suitable security level is about configured, and then can determine its update mechanism, the update for rear rumming agreement provides basis.
Step 24, the security level for determining the intelligent contract, and first transaction is asked based on the security level
It asks and carries out common recognition verifying；
That is, characteristic of this step based on different classes of intelligent contract, discriminatively carries out common recognition verifying to intelligent contract,
A kind of its implementation can be：
Step S1, based on the security level and security level and the corresponding relationship being pre-configured between rule is updated, really
The update rule of the fixed intelligent contract；
Step S2, common recognition verifying is carried out to first transaction request based on the update rule.
For step S1, it should be noted that the characteristic of intelligent contract as needed for different application scene is different,
Such as：Some application scenarios require intelligent contract that can not modify, some application scenarios require intelligent contract can multiparty collaboration repair
Change.Therefore, it is to include that the corresponding relationship being pre-configured between the security level in the present embodiment and update rule, which can be exemplified,：
First security level (lower), it is suitable for the application scenarios that weak contract services by force, correspond to the first kind and update rule
Then, i.e., contract is all can arbitrarily upgrade contract code；
Such as：In medical institutions' deployment contract, the application scenarios to safeguard individual subscriber health data, due to the contract
It will not influence the number one of user, therefore, after user authorizes medical institutions under normal circumstances, medical institutions can arbitrarily upgrade
Contract.
Second security level (higher), it is suitable for the application scenarios of multiparty collaboration, correspond to the second class and update rule, i.e.,
All sides of contract are in the scalable contract in signature rear for obtaining all or part of designated user；
Such as：It contracts in both sides, and by contract trustship in the application scenarios of the third party, the third party is all as contract
Side, when updating upgrading contract, the signer for needing to obtain both sides or at least one party can have the right to carry out contract more new liter
Grade.
Third security level (highest), it is suitable for most application scenarios on block chain, correspond to third class and update
Rule, i.e. contract can not be updated upgrading once deployment success, either all sides of contract or other users to it.It can
Choosing, the security level that third security level can be defaulted as block chain.
In addition, though only illustrating three kinds of security levels herein, but understandable is that security level is flexibly to divide
, the corresponding rule that updates is also flexibly configurable.Therefore, the division of other security levels and its update rule is also at this
Within the protection scope of embodiment.
Based on the exemplary security level of step S1 and the corresponding relationship between rule is updated, the common recognition in step S2 verifies step
The first rapid implementation can be：
If the intelligence contract is the first security level, it is determined that it is that the first kind updates rule that it, which updates rule,；Further
Ground can update rule based on the first kind, carry out common recognition verifying to the signature having on the more new information；If the update
The signature of first transaction node is had in information, it is determined that the result for verifying of knowing together is to pass through.
That is, as long as all sides of contract can be can reach as a result, in same address by verifying by having the signature of all sides of contract
The purpose of any upgrading contract code.
Common recognition verification step second of implementation can be：
If the intelligence contract is the second security level, it is determined that it is that the second class updates rule that it, which updates rule,；Further
Ground can update rule based on second class, carry out common recognition verifying to the signature having on the more new information；If the update
The signature of target transaction node is had in information, it is determined that the result for verifying of knowing together is to pass through；Wherein, the target transaction node
Including：The corresponding node of participant of first transaction node and the intelligent contract.Participant can be whole participants,
It is also possible to subparticipation side；Specifically depending on the more new demand by all participants when formulating intelligent contract.
Common recognition verification step the third implementation can be：
If the intelligence contract is third security level, it is determined that it is that third class updates rule that it, which updates rule,；Further
Ground can update rule based on the third class, determine that the result of the common recognition verifying is not pass through.
That is, when node of knowing together determines that the intelligence contract is nonupdatable third security level, without verifying signature etc.
Information directly determines verifying and does not pass through.
Step 26 responds or refuses to respond first transaction request according to the result of common recognition verifying.
It is understandable to be, when the result of common recognition verifying is not pass through, then first transaction request is refused to respond, is not permitted
Perhaps upgrading is updated to the intelligence contract；
When common recognition verifying result be by when, then respond first transaction request, allow to the intelligence contract progress more
New upgrading；
Wherein, update, which upgrades a kind of implementation of intelligent contract, to be：
The address information for the memory node for including in first transaction request is obtained, is stored in the memory node
State intelligent contract；Verification result of knowing together be by when, the address information based on memory node obtains intelligent contract；Based on institute
More new information is stated, the intelligent contract is updated.
Wherein, the effect of memory node is：Intelligent contract used, the memory node when trading between store transaction node
Node can be participated in for contract, be also possible to other nodes.
As it can be seen that different demands of the present embodiment based on application scenarios, divide the security level of intelligent contract, obtain
The security level of multiple and different characteristics, such as：All sides unconditionally update the upgrading rank of contract, all sides have ready conditions more new liter
The rank of grade, rank of non-renewable upgrading contract etc..Suitable update mechanism is configured for the intelligent contract of each security level,
To be discriminatively updated upgrading to the intelligent contract of different security levels, compared with prior art, can not influence it is credible
On the basis of mechanism, the exploitation iteration and the flexibility of deployment of intelligent contract are effectively improved.
Fig. 4 a and Fig. 4 b are a kind of schematic diagram for intelligent contract update method that another embodiment of this specification provides, below
This method is illustrated in conjunction with Fig. 4 a and Fig. 4 b：
A referring to fig. 4, a kind of example can specifically include following steps：
Step 1., assume to trade between node 2 and node 3, both sides pass through interaction under line, are abided by with to formulate needs
Intelligent contract and its security level, and sign on intelligent contract；
Wherein, intelligent contract can be exemplified as：
When second day maximum temperature is greater than 38 °, account 3 of the account 2 on node 3 on node 2 pays 100 yuan；
Account 2 payment 100 of the account 3 on node 2 when second day maximum temperature is less than or equal to 38 °, on node 3
Member；
For convenient for subsequent change, both sides are that the security level of intelligent contract configuration is the second security level.
Step 2., node 2 or node 3 by intelligent contract trustship to node 1；
That is, node 2 and node 3 entrust believable node 1 for all sides of intelligent contract jointly.
3., by node 1 step initiates the transaction request that the intelligence contract is submitted to cochain；
Common recognition verifying is carried out to the transaction request by common recognition node, if the result of common recognition verifying is to pass through, allows the intelligence
Energy contract cochain, and it is deposited into memory node；
Wherein, common recognition, which is verified, includes：Whether the signature for verifying the node 1, node 2 and the node 3 that have on intelligent contract closes
Method；
Step 4., node 2 and node 3 by interaction under line, reach common understanding to the more new information of contract, on more new information
Signature；
Such as：Node 2 and the corresponding user both sides of node 3 may all feel 38 ° in contract it is unreasonable, agree to by 38 °
35 ° are changed to, then contract more new information (being changed to 35 ° for 38 °) is constructed by any side, and sign；Then, it is initiated to another party
Update the request of contract, another party verifying more new information is errorless and other side's signature it is legal after, also sign；
5., from node 2 or node 3 step is initiated to update request to node 1；
Correspondingly, node 1 first looks at the security level and its corresponding update rule of the intelligence contract；Then, it verifies
Update whether request meets the requirement for updating rule；If so, signature, and execute step 6.；
Step 6., initiate by more new information submit cochain transaction request；
Common recognition verifying is carried out to the transaction request by common recognition node, if the result of common recognition verifying is to pass through, allows this more
New information cochain finds the intelligence contract, and then 38 ° in contract are revised as with the address information based on memory node
35°。
B referring to fig. 4 exists with the difference of the example shown shown in Fig. 4 a, in this example step 1. 4. can for
It is carried out on line.Assuming that node 2 is transaction initiator, the implementation of step 1. can be briefly described as follows：
Node 2 formulates contract based on the rights and duties of both sides, and after signature, initiates the first transaction to block chain and asks
It asks, the identity information of node 3 is carried in the first transaction request；
Node 3 verifies the signature of node 2 and the content of intelligent contract, if being verified, after signature, to area
Block chain initiates the second transaction request, and the identity information of node 2 is carried in the second transaction request；
Node 2 verifies the signature of node 3, if being verified, will have the intelligence that node 2 and node 3 are signed
Contract trustship submits cochain after being verified by node 1 to node 1.
The implementation of step 4. can be briefly described as follows：
The content that node 2 is modified based on needs formulates the more new information of intelligent contract, and after signature, sends out to block chain
Third transaction request is played, the identity information of node 3 is carried in third transaction request；
Node 3 verifies the signature of node 2 and the content of more new information, if being verified, after signature, to area
Block chain initiates the 4th transaction request, and the identity information of node 2 is carried in the 4th transaction request；
Node 2 verifies the signature of node 3, if being verified, will have the update that node 2 and node 3 are signed
Information trustship submits cochain after being verified by node 1 to node 1.
As it can be seen that the present embodiment configures a security level before cochain intelligence contract for it, block chain can determine it as a result,
Corresponding update rule；In turn, in subsequent update intelligence contract, common recognition can be carried out based on its corresponding update rule and is tested
Card, to reach the intelligent contract for different security levels, is updated upgrading using its corresponding update rule.With existing skill
Art is compared, and the exploitation iteration of intelligent contract and the flexibility of deployment on the basis of not influencing trusted mechanism, can be effectively improved.
In addition, for simple description, therefore, it is stated as a series of action groups for above method embodiment
It closes, but those skilled in the art should understand that, embodiment of the present invention is not limited by the described action sequence, because
