Endorsement strategy determines method, apparatus, electronic equipment, storage mediumTechnical field
The present invention relates to computer application technology more particularly to a kind of endorsement strategy determination sides based on block chainMethod, device, electronic equipment, storage medium.
Background technology
Block chain is a kind of technology of shared account book.Specifically, block chain is Distributed Storage, point-to-point biographyThe new application pattern of the computer technologies such as defeated, common recognition mechanism, Encryption Algorithm.So-called common recognition mechanism is realized in block catenary systemThe mathematical algorithm for trusting, obtaining equity is established between different nodes.
Intelligent contract is applied to block chain technology.One intelligent contract is a set of promise defined in digital form(promises), including contract participant can execute these agreements promised to undertake above.A set of promise refers to that contract participates in(often mutual) rights and duties of Fang Tongyi.These promises define the essence and purpose of contract.It is closed with a saleAbout exemplary.Seller, which promises to undertake, sends cargo, the rational payment for goods of buyer's acceptance and guarantee.The intelligent contract of digital form meaning is establishedRights and duties, be to be executed by a computer or computer network.Diversification based on contract and convertible, intelligenceThe business that contract is carried is very flexible, and not only service logic itself is very flexible, but also the related participant of service logic is alsoChangeable.
For raising efficiency, in block chain the execution of intelligent contract be not necessarily required to whole nodes (including node and endorsementNode) it is carried out.In block chain technology, each transaction can promote confidence level by way of node endorsement.From systemOverall performance is considered, every time the calling of intelligence contract, and performed node too many (such as cannot need whole sections in block chainPut to execute), the expense otherwise known together and checked can be bigger.Consider from security of system, every time the calling of intelligence contract, instituteThe node of execution cannot very little (such as only there are one nodes to execute), and otherwise implementing result is easily controlled and distorts.
During existing block chain is realized, only support for single intelligent contract (Smart Contract orChaincode static endorsement strategy) is specified.That is, for specified intelligent contract, no matter how many function tune inside contractWith, need the node endorsed with the rule of endorsement to be as.The single intelligence contract layer and endorsement strategy of static state can not expireThe demand of sufficient practical application scene.

Fig. 1 shows the according to the ... of the embodiment of the present invention kind of flow chart that method is determined based on the endorsement strategy of block chain.GinsengFig. 1 is examined, the endorsement strategy based on block chain determines that method may comprise steps of：
Step S110：The business function and the parameter transaction needed for business function for determining transaction calling；
Step S120：Endorsement strategy, the endorsement strategy packet are determined according to the business function and/or the parameter transactionInclude endorsement node and endorsement rule；And
Step S130：Endorsement request is sent to the endorsement node of identified endorsement strategy, so that verification node is according to instituteIt states business function and/or the parameter transaction and determines endorsement strategy again.
In the endorsement strategy determination method based on block chain of exemplary embodiments of the present invention, the present invention passes through dynamicThe endorsement strategy of state meets different service logics, can also increase the execution efficiency of transaction while compromise between security.
Specifically, block chain includes multiple nodes.Endorsement node is to be chosen from multiple nodes for executing endorsementThe node of rule.
The node refers to the communication entity of block chain.Node belongs to a logical concept, different types of multipleNode may operate in above the same physical server.
The type of node can be client or submission client (client or submitting-client), peerNode and common recognition service node or voter's node.Client submits client to submit an actual transaction to endorsement nodeIt calls, and merchandises motion (trans- to sequence service node (a kind of common recognition service node or voter's node) broadcastproposal).Client indicates the entity of terminal user, merchandises for creating and calls transaction, can and meanwhile and node and rowSequence service node is communicated.Obviously, to realize that communication must be first coupled to a node communicated with block chain.Client canTo be connected on the arbitrary node of its selection.
Peer nodes submit transaction, safeguard the copy of state and general ledger (ledger).In addition, node can endorse.Specifically, peer nodes receive the ordered state update from sequence service node (ordering service), state is moreIt is newly stored in the form of block, while node is additionally operable to maintenance state and general ledger.Executing the node of endorsement rule can makeFor node of endorsing, functionally, endorsement node is mainly used for responding the endorsement request of specific chain code, is submitted in transactionIt is preceding that endorsement processing is carried out to transaction.
Common recognition service node or voter's node are the nodes for running communication service, realize transmission and ensure.For example, atomBroadcast and completely sequence are broadcasted.Specifically, sequence service node is a kind of common recognition service node or voter's node.Sequence clothesBusiness node forms sequence service, and sequence service may be implemented as various ways.Such as, from the service of a centralizationTo distributed agreement.Sequence service provides the shared communication channel for leading to client (client) and peer nodes, providesInclude the message broadcast service of transaction.It is that can be carried out to all nodes by this channel when client is connected to channelBroadcast message, you can complete to send the task of message to all block chain nodes.
In the embodiment for the related realization that block chain is endorsed, in the net of transferring accounts that one is made of participant A, B, CNetwork (and three nodes all can be endorse node), the business of required progress is bipartite transfers accounts.It transfers accounts x to B for AMember, in the embodiment of related realization, it is therefore possible to use endorsement strategy for example have 3 kinds：
1) any of three nodes node is endorsed
According to the endorsement strategy, then the client of A needs to send transaction request to any one node, obtains endorsement resultAfterwards directly transaction is sent to sequence service node.A, B, C tri- confirms that node contains the transaction by service node acquisition of sortingBlock write the result into respective account book after verifying the endorsement strategy of the transaction and the version of the results set after transferring accounts.Potential risks are, under the endorsement strategy, it is understood that there may be A only need the endorsement node by A to generate endorsement as a result, by AEndorsement node can forge the result set after transferring accounts, and cannot achieve the safety transferred accounts；
2) any two node is endorsed in three nodes
According to the endorsement strategy, collude with if A and C are ganged up, for all A to the money transfer transactions of B, A all by A andThe endorsement node of C is endorsed, and the endorsement node of A and C forges the result set after transferring accounts together, then A still has cheatingPossibility.
3) three nodes are carried out at the same time endorsement.
According to the endorsement strategy, if the endorsement node C as the unrelated participant in transferring accounts this transaction to B in A is notThe endorsement of the transaction is responded, then this money transfer transactions can not obtain the endorsement of three nodes, also can not successful execution.Meanwhile threeThe endorsement that a node is carried out at the same time endorsement is less efficient.
It can be seen that the realization of these static endorsement strategies, it can not compromise between security and efficiency.
It is such in order to prevent to happen, safety and the efficiency of the transaction of block chain are improved, present invention employs dynamicsEndorsement strategy.Illustrate specific embodiments of the present invention with reference to Fig. 2, Fig. 2 shows according to the one of the specific embodiment of the inventionKind determines the sequence diagram of method based on the endorsement strategy of block chain.
In the embodiment shown in Figure 2, step S202 is first carried out in client 291：Determine the business function that transaction is calledAnd the parameter transaction needed for business function.
Business function describes the parameter needed for type of transaction and transaction.In certain embodiments, business function canTo state the form of Transfer (from, to, assets) as, wherein Transfer indicates the function corresponding to the service logicTitle, from, to, assets are then corresponding function parameters (i.e. parameter transaction), and from indicates that the assets side of producing, to indicate moneyRecipient is produced, assets indicates shifted assets.If the business function, for transferring accounts, assets indicates x members.For example,Transfer (A, B, 20) indicates that A transfers accounts 20 yuan to B.In other specific embodiments, for example, two people of A, B possesses one respectively30% and 70% assets of automobile, if A by the assets transfer of 15% automobile to C, can with Transfer (A, C,15%) it indicates.
Then client 291 executes step S204：Endorsement plan is determined according to the business function and/or the parameter transactionSlightly, the endorsement strategy includes endorsement node and endorsement rule.
Specifically, step S204 may include being based on endorsement strategic function according to the business function and/or the friendshipEasy parameter determines endorsement strategy, and the endorsement strategic function is described from the business function and/or the parameter transaction to describedThe conversion of endorsement strategy.
In some embodiments, the parameter transaction includes each side to participate in business, and the endorsement strategy is according to the friendshipEasy parameter is using the node of each side to participate in business as endorsement node.The endorsement strategic function can be deployed in each nodeOn.
Specifically, in this embodiment, a kind of mode of possible realization of endorsement strategy of Transfer isTransferEndorsementPolicy=AND (Peer_From, Peer_To) indicates, for this service logic of Transfer, to needSimultaneously by the endorsement of the endorsement node corresponding to from and to.In the case that A transfers accounts X members to B, indicates while needing A's and BNode is endorsed；If B transfers accounts to C, substitutes into and understand while the node of B and C being needed to endorse.
In further embodiments, the parameter transaction includes the assets participated in business, and the endorsement strategy is according toAssets are using all nodes with the assets before transaction and after transaction as endorsement node.
Specifically, in this embodiment, if it is multiple participants that the owner of Asset is corresponding, strategy one of endorsingKind is possible to be achieved in that TransferEndorsementPolicy=AND (Peer_AssetOwners, Peer_AssetRecievers).Peer_AssetOwners indicates that assets owning side, Peer_AssetRecievers indicate that assets connectDebit.For example, A and B co-own some assets --- an automobile, the ratio that wherein A possesses are the ratios that 30%, B possessesIt is 70%.If A gives C to by its ownership transfer a part of (15%), then it represents that be Transfer (A, C, 15%Car).At this point,It substitutes into above-mentioned formula and obtains TransferEndorsementPolicy=AND (A, B, C), indicate the transaction while needing A, BIt endorses with the node of C.In this embodiment, the assets (such as Asset Type) for including by parameter transaction, to determineWhether it has multiple participants, thus, it is possible to which the incoherent C that will merchandise, is also contained in the set of identified endorsement nodeIn.
In having some embodiments, it can also be determined according to different business functions (business function name) and be merchandised using whichParameter determines endorsement node.For example, in some embodiments, above-mentioned transfer accounts uses different function names with assets transfer, thenWhich parameter transaction endorsement node can be determined using to determine according to function name.
Then client 291 executes step S206：Client 291 is sent out to the endorsement node 292 of identified endorsement strategyEndorsement is sent to ask, so that the endorsement node executes the endorsement rule of identified endorsement strategy.
After endorsement node 292 receives endorsement request, endorsement rule is executed.Specifically, in some embodiments, the back of the bodyIncluding at least the parameter transaction needed for the business function and business function, the endorsement node 292 can be according to institute for book requestIt states business function and/or the parameter transaction determines the endorsement strategy to execute the endorsement rule of identified endorsement strategy.Further, endorsement node 292 asks mock trading according to the endorsement, and generates endorsement signature according to mock trading, describedConfidence level of the endorsement signature for improving the transaction.
Later, endorsement node 292 executes step S208, and endorsement node 292 returns to endorsement result and corresponding endorsement signatureTo client 291.
Later, client 291 executes step S210, after collecting the endorsement result for meeting endorsement strategy and signature, the row of transmissionSequence service node is ranked up.It is appreciated that the endorsement node of different number is had due to merchandising every time, sequence serviceNode 293 can determine the minimum endorsement needed for this time merchandising according to the instruction for the startup sequence service that client 291 is sentThe quantity (part that also can be used as endorsement strategy determines in step S202) of signature, when sequence service node 293 receives footAfter enough endorsement signatures (quantity for being more than required minimum endorsement signature), executes step S212 and sent out to verification node 294Send Transaction Information.Transaction Information may include the block comprising transaction and each endorsement strategy endorsed performed by node.
Followed by, respectively verification node 294 executes step S214 according to the business function and/or the parameter transaction againDetermine endorsement strategy；
Then, respectively verification node 294 (can also be client 291) executes step S216 after receiving Transaction Information,Verification endorsement strategy and transaction.Specifically, step S216 may include steps of：According to identified endorsement policy validationEndorsement strategy performed by each endorsement node obtains the first verification result (for example, the version of the endorsement strategy of both verificationsIt is whether identical, by verification if identical, if differing authentication failed)；Verification includes the block of transaction, obtains the second verificationAs a result.
Finally, respectively verification node 294 executes step S218, according to first verification result and the second verification result by instituteIt states in the block write-in account book of transaction (if for example, the first verification result and the second verification result are all to be verified, by transactionBlock write verification node 294 account book).
