Specific embodiment

Herein, block chain virtual machine refers to that each block chain node is executing the execution program relied on when transaction.Block chain virtual machine provides performing environment for the transaction of block chain.

It should be noted that block chain virtual machine not only can be the ether mill virtual machine recorded in the agreement of ether mill(Ethereum Virtual Machine, EVM) can also be signified in other block chain agreements in addition to the agreement of ether millVirtual machine.

Herein, intelligent contract compiler will refer to for that programming language (such as solidity language) will be used to writeIntelligent contract is compiled into the journey for the machine language (such as bytecode, binary code) that block chain virtual machine can be identified and be executedSequence.It should be noted that being deployed in the intelligent contract in block chain network, generally refer to after intelligent contract compiler compilesIntelligent contract, i.e. the intelligent contract of bytecode form or binary code repressentation.

In ether mill agreement or the other similar block chain agreement in ether mill agreement, block chain virtual machine is in local dimensionThe mapping relations (as shown in table 1 below) between several groups instruction and operation are protected, also, block chain virtual machine is locally also deployed withThe code logic of each operation in table 1.1~command N of instruction is all the instruction of the defaulted support of block chain virtual machine, instruction 1~command N constitutes the instruction set of block chain virtual machine.Block chain virtual machine is when calling intelligent contract, if from intelligent contractIn read any instruction in table 1, the code logic for executing the corresponding operation of the instruction will be triggered.It should be noted thatInstruction as described herein is usually bytecode form or binary code repressentation.

Command N	Operate N

Table 1

Therefore, if it is desired to allowing any operation in block chain virtual machine execution table 1, it is necessary to be wanted in block chain virtual machineIt calls in intelligent contract, is previously written the corresponding instruction of the operation.It means that intelligent contract compiler is in advance to the intelligenceWhen contract is compiled, statement in intelligent contract (writing using programming language) can be realized to the interior of any operation in table 1Appearance is compiled into corresponding instruction, so that block chain virtual machine can identify.This requires intelligent contract compiler is also required to default1~command N of instruction in support matrix 1,1~command N of instruction constitute the instruction set of intelligent contract compiler.

In short, in ether mill agreement or the other similar block chain agreement in ether mill agreement, usually by block chainVirtual machine, intelligent contract compiler and the specific business demand of intelligent contract cooperative achievement.

But existing ether mill virtual machine is limited in the operation that locally default is supported, and business demand is complicatedMultiplicity.For example, existing ether mill virtual machine and the intelligent contract compiler in ether mill do not default the following operation of support, leadIt causes in the framework of existing ether mill, cannot achieve some dependent on the business demand operated as follows:

1, it is based on the coding-decoding operation of 64 printable characters (BASE64).

2, RSA signature verification operation；Wherein, RSA Algorithm be 1977 by Peter Lonard Lee Vista (Ron Rivest),A Di Shamir (Adi Shamir) and Leonard A Deman (Leonard Adleman), RSA Algorithm also hence obtains one's name.

3, to the processing operation of JS object numbered musical notation (JavaScript Object Notation, JSON) data；Wherein,JSON is a kind of common data interchange format, and JSON data are that have the data of this data interchange format.

4, to the processing operation of extensible markup language (eXtensible Markup Language, XML) data；ItsIn, XML is a kind of common data interchange format, and XML data is that have the data of this data interchange format.

5, the operation of the transaction Hash of currently performed transaction is obtained.

6, for a money transfer transactions, under the premise of not exposing the assets remaining sum and transfer amounts of the people that transfers accounts, judgement turnsWhether the assets remaining sum of account people pays the transfer amounts of this money transfer transactions enough.

Do not defaulted due to the intelligent contract compiler of existing ether mill virtual machine and ether mill and supports asking for aforesaid operationsTherefore topic in the prior art, is operated for any of the above-described kind, general use directly writes the code logic for realizing the operationEnter the mode of intelligent contract, so that ether mill virtual machine when executing transaction, calls intelligent contract to execute the code of the operationLogic.Although the code logic of aforesaid operations is written that is, ether mill virtual machine does not default support aforesaid operationsIntelligent contract, and allow the ether mill virtual machine call intelligence contract, ether mill virtual machine also may be implemented and execute aforesaid operationsPurpose.

But in practice, the local code logic disposed in advance is directly executed compared to ether mill virtual machine, ether mill is emptyThe efficiency that quasi- machine executes the code logic in intelligent contract is lower.

And core of the invention thought is, on the one hand, be extended, increase above-mentioned to the instruction set of block chain virtual machineCorresponding instruction is operated, while in the corresponding code logic of the local aforesaid operations of deployment in advance of block chain virtual machine, so that blockChain virtual machine can default support aforesaid operations.On the other hand, the instruction set of intelligent contract compiler is also extended, is increasedThe corresponding instruction of aforesaid operations.It wherein, is that the instruction set of block chain virtual machine is increased corresponding to the operation for same operationInstruction should be consistent with the increased instruction corresponding to the operation of instruction set for intelligence contract compiler.As shown in table 2.

In this way, by taking above-mentioned BASE64 encoding operation as an example, it can be when writing intelligent contract using programming language, in intelligenceIt can state to call BASE64 encoding operation in contract, intelligent contract compiler is when being compiled intelligent contract, by this section of soundIt is bright to be compiled into BASE64 coded command.After the intelligence contract is deployed in block chain network, user, can in the business of initiationIt is seted the tone with initiating to refer in transaction in business with the intelligence contract, in this way, block chain virtual machine is when the business of execution is initiated to trade, justThe intelligence contract can be called, and when reading BASE64 coded command from the intelligence contract, triggering is performed locally correspondingBASE64 codimg logic, to realize BASE64 encoding operation.

In order to make those skilled in the art more fully understand the technical solution in this specification embodiment, below in conjunction with thisAttached drawing in specification embodiment is described in detail the technical solution in this specification embodiment, it is clear that describedEmbodiment is only a part of the embodiment of this specification, instead of all the embodiments.The embodiment of base in this manual,Those of ordinary skill in the art's every other embodiment obtained, all should belong to the range of protection.

Below in conjunction with attached drawing, the technical solution that each embodiment of this specification provides is described in detail.It should be noted that due toThe technical idea that each embodiment below is based on all be it is similar, therefore, each embodiment hereafter can be mutually referring to understanding.

Embodiment one

Fig. 1 is a kind of process signal for coding method based on block chain intelligence contract that this specification embodiment providesFigure, comprising the following steps:

S100: the node in block chain network obtains business and initiates to trade and be broadcast to other nodes.

S102: for each node in the block chain network, which leads to when executing the business initiation transactionBlock chain virtual machine is crossed, the business intelligence contract is called.

S104: the node is by block chain virtual machine, according to the BASE64 coded command in the business intelligence contract, touchingHair executes the BASE64 codimg logic, to perform the encoding operation to data to be encoded.

In the present embodiment, it needs to be pre-configured with for block chain network, so that:

1) include BASE64 coded command in the instruction set of block chain virtual machine, also, be deployed in block chain virtual machineBASE64 codimg logic corresponding to the BASE64 coded command.

It 2) include the BASE64 coded command in the instruction set of intelligent contract compiler, through the intelligent contract compilerIt include the BASE64 coded command in the business intelligence contract of compiling.

3) it is disposed in block chain network and is stated business intelligence contract.

The business intelligence contract is to need to call intelligent contract corresponding to the business of BASE64 encoding function.

In each embodiment of this explanation, block chain network includes multiple nodes.Wherein, from software view, nodeRefer to the block chain program for realizing block chain function；From hardware view, node, which refers to, is equipped with block chain programUser equipment.In practical applications, each node can dock at least one client (or wallet), the transaction in block chainUsually client constructs.

The transaction described in each embodiment of this explanation (transaction) refers to that user passes through the visitor of block chainThe creation of family end, and a data for needing finally to be distributed in the distributed data base of block chain.Transaction is in block chain agreementA kind of data structure arranged, a data will be stored in block chain, it is necessary to be packaged into transaction.

Transaction in block chain, there are points of the transaction of narrow sense and the transaction of broad sense.The transaction of narrow sense refer to user toOne value Transfer of block chain publication；For example, transaction can be user in block in traditional bit coin block chain networkOne initiated in chain transfers accounts.And the transaction of broad sense refers to the business number being intended to business that user issues to block chainAccording to；For example, operator can build alliance's chain based on actual business demand, relies on alliance's chain and dispose some and valueShift it is unrelated it is other types of in line service (for example, business of renting a house, vehicle scheduling business, settlement of insurance claim business, credit takeBusiness, medical services etc.), and in this kind of alliance's chain, transaction, which can be one that user issues in alliance's chain, has business meaningThe service message or service request of figure.

In block chain network, user initiates business usually in the form of transaction.Specifically, node needs to obtain business hairIf playing the above-mentioned business intelligence contract of transaction is not the unique intelligent contract disposed in block chain network, business initiates transactionIn can also indicate the Contract ID of the business intelligence contract, the intelligent contract of required calling when executing clearly to trade.

Wherein, it is usually that user is constructed by client and is sent to node that business, which initiates transaction,.In general, blockThe client of chain network docking and each user correspond.

Business after being initiated transaction and being broadcast to other nodes by node, and for each node, the node is receivingIt states business to initiate after trading, needs to execute the business by business intelligence contract described in block chain virtual machine call and initiate to hand overEasily.Herein it should be noted that in block chain network, block chain virtual machine is deployed on each node, node executes friendshipYi Shi, the block chain virtual machine actually disposed on node are executing transaction.

In example 1, after business intelligence contract described in block chain virtual machine call, it can read the business intelligenceBytecode or binary code in contract simultaneously execute, when reading the BASE64 coded command in the business intelligence contract,It is equivalent to and specifies and need to carry out BASE64 encoding operation at this time, therefore, block chain virtual machine can trigger at this time executes preparatory portionIt is deployed on local BASE64 codimg logic, to perform the encoding operation to data to be encoded.

In practical applications, depending on the difference of specific business demand, data to be encoded can be contained within the business hairIt rises in transaction, also may include in the business intelligence contract, can also be that block chain virtual machine is executing the industryIt is generated when business initiation transaction.

It is initiated except transaction in addition, each node executes business except through block chain virtual machine, it is also necessary to be based on common recognition machineThe business is initiated transaction write-in block chain by system.

It is further to note that if block chain virtual machine refers to according to the BASE64 coding in the business intelligence contractTriggering is enabled to execute BASE64 codimg logic, then, used data transfer mode is usually that stack transmits (i.e. in the process of implementationIn data write-in stack after generally BASE64 being encoded), still, for the data after BASE64 is encoded, numberIt is unfixed according to length, if by the way of stack transmitting, it is desirable to may all be preset when data length for variousCorresponding BASE64 coded command, implements complex.

For this purpose, embodiment two below provides another coding method based on block chain intelligence contract.

Figure 18 is a kind of process signal for transfer account method based on block chain intelligence contract that this specification embodiment providesFigure, includes the following steps:

S1800: the node in block chain network obtains money transfer transactions by external account of transferring accounts and is broadcast to other nodes.

I.e. node receives the money transfer transactions that client (having logged in external account of transferring accounts) constructs and send.

S1802: for each node in the block chain network, which passes through when executing the money transfer transactionsBlock chain virtual machine calls the business intelligence contract and according to the discrepancy checking command in the business intelligence contract, triggeringExecute the discrepancy check logic.

S1804: if check results be it is yes, which is executed in the business intelligence contract by block chain virtual machineUser's asset table modify logic.

In the framework of ether mill, each external account and each user are corresponded, the behavior reality of transferring accounts between two usersUpper is exactly the behavior of transferring accounts between two external accounts.

Assuming that external account A wants to transfer accounts to external account B, then, external account A can be constructed comprising transfer amounts firstWith the money transfer transactions of the account address of external account B, then, which can be broadcast to each section in block chain networkPoint.After each node is verified money transfer transactions, money transfer transactions are executed, external account B is written into transfer amounts.

It should be noted that the remaining sum that each node generally comprises verifying external account A to the verifying item of money transfer transactions isNo abundance, i.e., whether the remaining sum of external account A is greater than or equal to transfer amounts, if so, being verified.It means that existingIn the framework of some ether mills, if to transfer accounts, the account balance and transfer amounts for the people that transfers accounts can all be exposed to areaEach node in block chain network.

In embodiment 13, a kind of business demand is actually given, i.e., between the node in block chain networkA money transfer transactions, not expose transfer accounts user assets remaining sum and transfer amounts under the premise of, judgement transfer accounts user'sThe whether enough transfer of payment amount of money of assets remaining sum.

In order to meet this business demand, present invention employs a kind of new models of transferring accounts, and do not use block chain networkIn external account in remaining sum transferred accounts and receipt on account, but create business intelligence contract, in business intelligence contract againBuild the assets system of a user.In this assets system, there is no assets remaining sum concept, the assets that each user possessesIt is the equal of a kind of virtual object, user spends out an assets, this assets will disappear.

Specifically, the business intelligence contract is disposed in block chain network, the business intelligence contract is corresponding with userAsset table, user's asset table (correspond) corresponding assets for recording each external account with each user, forAny assets, the assets are the data comprising encrypting the amount of money, which obtained after encrypting to the amount of money of the assets's.

The following table 3 gives user's asset table with showing column.

External account 1	Assets 1, assets 2
		External account 2	Assets 3, assets 4, assets 5
External account 3	Assets 6

Table 3

For example, external account 1 is transferred accounts 120 yuan to external account 2, it is assumed that the amount of money of assets 1 is 100 yuan, the amount of money of assets 2It is 50 yuan, then external account 1 needs cost to fall oneself assets 1 and assets 2, then, assets 1 and assets 2 disappear, and produceAssets 7 (amount of money is 120 yuan) and assets 8 (amount of money is 30 yuan), external account 1 obtains assets 8, and external account 2 obtains assets 7.As it can be seen that assets 1+ assets 2 are actually this input transferred accounts, assets 7+ assets 8 are actually the output that this transfers accounts.ByAfter this pen is transferred accounts, table 3 will be updated the table 4 being as follows.

External account 1	Assets 8
		External account 2	Assets 3, assets 4, assets 5, assets 7
External account 3	Assets 6

Table 3

In this way, in the present invention, for the problem that a money transfer transactions, verifying remaining sum is converted into verifying input and outputThe problem of whether balancing.Since the amount of money of each assets is actually to encrypt, because being not exposed to block chain virtual machine, thisIt is meant that requiring block chain virtual machine when executing money transfer transactions, using homomorphic encryption algorithm (such as PedersenCommitment algorithm), whether the assets for verifying input are equal with the assets of output, if check results are yes, it is meant thatThis money transfer transactions is feasible (remaining sum for being equivalent to the people that illustrates to transfer accounts is sufficient).

For specifically embodiment, in the present embodiment 13, needs to be pre-configured with for block chain network, make:

It 1) include entering and leaving checking command, also, be deployed in block chain virtual machine pair in the instruction set of block chain virtual machineThe discrepancy check logic for Hash acquisition instruction of trading described in Ying Yu.

Wherein, the discrepancy check logic includes:, using homomorphic encryption algorithm, to verify this turn for any money transfer transactionsThe sum of the amount of money for the small change assets that the amount of money of the specified assets of transferring accounts of account transaction and the money transfer transactions are specified, if transfer accounts equal to thisThe sum of the amount of money of the specified each cost assets of transaction.

It should also be noted that, the money transfer transactions are actually that previously described business initiates transaction, only thisThe business at place is specially to encrypt transferred account service.

2) include the discrepancy checking command in the instruction set of intelligent contract compiler, compiled through the intelligent contract compilerIt include the discrepancy checking command in the business intelligence contract translated.

3) it is disposed in block chain network and is stated business intelligence contract.

The business intelligence contract is the intelligent contract of the function of transferring accounts for realizing hiding transfer amounts and assets remaining sum.

In step S1800, node actually refers to the corresponding node of the user that transfers accounts.External account of transferring accounts actually refers toThe external account that the user that transfers accounts is controlled.

Node obtains money transfer transactions by external account of transferring accounts, and the user that actually transfers accounts logs in client (or " moneyPacket "), it constructs money transfer transactions and is sent to node.

It include transfer accounts assets, small change assets and at least one cost assets in the money transfer transactions.Wherein, described at least oneA cost assets are actually to be input to this assets transferred accounts, and assets of transferring accounts are actually that this pen is transferred accounts with small change assetsThe assets of output.

In embodiment 13, after business intelligence contract described in block chain virtual machine call, the business intelligence can readIt bytecode in contract or binary code and can execute, when reading the discrepancy checking command in the business intelligence contract,It is equivalent to and specifies and need to carry out discrepancy verification operation at this time, therefore, block chain virtual machine can trigger execution deployment in advance at this timeIn local discrepancy check logic, to use homomorphic encryption algorithm, the amount of money and the small change of assets of transferring accounts described in verification are providedWhether the sum of amount of money of production is equal to the sum of the amount of money of each cost assets.

If check results be it is yes, illustrate that this money transfer transactions is feasible.In turn, block chain virtual machine needs to be implementedThis money transfer transactions modifies user's asset table according to money transfer transactions.The user's asset table for modifying user's asset table modifies logicIt is actually pre-written into business intelligence contract.It is external account of transferring accounts described in releasing that user's asset table, which modifies logic,With the corresponding relationship of each cost assets, the corresponding relationship of transfer accounts described in foundation external account and the small change assets, and receipts are establishedThe corresponding relationship of account external account and the assets of transferring accounts.

In addition, in practical applications, occurring following situation in order to prevent: certain malicious users when initiating money transfer transactions,Negative is set by the actual value for the assets of transferring accounts for including in money transfer transactions, other people assets are stolen in a manner of transferring accounts；WithAnd user is initiating money transfer transactions operation error, sets negative for the actual value for the small change assets for including in money transfer transactions,The amount of money of the practical assets produced of user is caused to be greater than the amount of money for assets of transferring accounts, the method that can use zero-knowledge proof is turningUnder the actual value of account assets and all sightless situation of the actual value of small change assets, verification transfer accounts assets actual value withWhether the actual value of small change assets falls within specified numberical range, and such as (0,2⁶⁴].If check results be it is yes, just eliminate withOn a possibility that happening.

Specifically, it in embodiment 13, can be pre-configured with further directed to block chain network, so that:

It 4) further include amount of money checking command in the instruction set of block chain virtual machine, also, also disposed in block chain virtual machineThere is the amount of money check logic corresponding to the amount of money checking command.

5) further include the amount of money checking command in the instruction set of the intelligent contract compiler, compiled through the intelligent contractIt translates in the business intelligence contract of device compiling also comprising the amount of money checking command.

It also needs to include the proof related data for realizing zero-knowledge proof based on this, in Client-initiated money transfer transactions(such as Bullet Proof, Borromean ring signatures).

Block chain virtual machine can trigger when reading the amount of money checking command in the business intelligence contract and execute localThe amount of money check logic disposed in advance, i.e., according to the proof related data, the amount of money for assets of transferring accounts described in verification is looked for describedWhether the amount of money of zero assets falls within specified numberical range.

In addition, can also include cost assets check logic in business intelligence contract, so that block in embodiment 13Chain virtual machine, can also be according to user's asset table when executing business intelligence contract, external account pair of transferring accounts described in verificationIt whether include each cost assets in the assets answered.If check results be it is yes, illustrate to transfer accounts user institute cost assets to be usedIt is one's own assets.

In addition, being directed to any assets, the data structure of the assets can also include characterizing the assets cost or non-costFirst state parameter.It can also include first state parameter interrelated logic in business intelligence contract, so as to block chain virtual machineWhen executing business intelligence contract, for each cost assets in money transfer transactions, the first state which includes is joinedNumber, verifies the whether non-cost of the cost assets.Also, the first state parameter interrelated logic further include: if be finally directed toThe result of the complete verification of the money transfer transactions is all, then, the first state parameter for including to the cost assets is repairedChange, so that modified first state parameter characterization cost assets cost.If finally for the money transfer transactionsHave in the result of complete verification any result be it is no, then money transfer transactions will fail, each cost assets not gone out by cost, fromIt need not so modify to first state parameter.

In addition, being directed to any assets, the data structure of the assets can also be present or absent including characterizing the assetsSecond state parameter.It can also include the second state parameter interrelated logic in business intelligence contract, so that block chain virtual machine existsWhen executing business intelligence contract, for each cost assets in the money transfer transactions, include according to the cost assets secondState parameter, verifying the cost assets whether there is.In this way, malicious user, which can be effectively prevented, fabricates not existing assets simultaneouslyIt is transferred accounts using imaginary assets.

It is further to note that if block chain virtual machine is according to the discrepancy checking command in the business intelligence contractIt is executed with the triggering of amount of money checking command and enters and leaves check logic and amount of money check logic, then, it is used in the process of implementation to countIt is usually stack transmitting according to transfer mode.Embodiment 14 below provides another side of transferring accounts based on block chain intelligence contractMethod (mode of precompile contract).

Embodiment 14

Figure 19 is a kind of transaction Hash acquisition methods based on block chain intelligence contract that this specification embodiment providesFlow diagram includes the following steps:

S1900: the node in block chain network obtains money transfer transactions by external account of transferring accounts and is broadcast to other nodes.

S1902: for each node in the block chain network, which passes through when executing the money transfer transactionsBlock chain virtual machine calls the business intelligence contract, and verifies intelligence according to the discrepancy in the business intelligence contractThe Contract ID of contract calls the discrepancy to verify intelligent contract.

S1904: the node executes the discrepancy according to the discrepancy checking command for entering and leaving and verifying in intelligent contract, triggeringCheck logic.

S1906: if check results be it is yes, which is executed in the business intelligence contract by block chain virtual machineUser's asset table modify logic.

In embodiment 14, need to be pre-configured with for block chain network, so that:

1) include transaction Hash acquisition instruction in the instruction set of block chain virtual machine, also, disposed in block chain virtual machineThere is the transaction Hash for corresponding to the transaction Hash acquisition instruction to obtain logic.

2) include the discrepancy checking command in the instruction set of intelligent contract compiler, compiled through the intelligent contract compilerThe Contract ID of intelligent contract is verified in the business intelligence contract translated comprising entering and leaving, it is preparatory portion that the discrepancy, which verifies intelligent contract,The intelligent contract being deployed in the block chain network.
