Specific embodiment

Example embodiments are described in detail here, and the example is illustrated in the accompanying drawings.Following description is related to When attached drawing, unless otherwise indicated, the same numbers in different drawings indicate the same or similar elements.Following exemplary embodiment Described in embodiment do not represent all embodiments consistent with this specification one or more embodiment.Phase Instead, they are only some aspects phases with the one or more embodiments of as detailed in the attached claim, this specification The example of consistent device and method.

It should be understood that the sequence that might not show and describe according to this specification in other embodiments executes The step of correlation method.In some other embodiments, step included by method can than described in this specification more It is more or less.In addition, single step described in this specification, may be broken down into other embodiments multiple steps into Row description；And multiple steps described in this specification, it may also be merged into single step progress in other embodiments Description.

Block chain is normally divided into three types: publicly-owned chain (Public Blockchain), privately owned chain (Private ) and alliance's chain (Consortium Blockchain) Blockchain.In addition, there are also a plurality of types of combinations, such as privately owned chain The different combinations such as+alliance chain, alliance's chain+publicly-owned chain.It is publicly-owned chain that wherein decentralization degree is highest.Publicly-owned chain with than Special coin, ether mill are representative, and the participant that publicly-owned chain is added can read data record on chain, participate in business and compete newly Book keeping operation power of block etc..

Moreover, each participant's (i.e. node) freely can be added and exit network, and carry out relevant operation.Privately owned chain then phase Instead, the write-in permission of the network is by some tissue or mechanism controls, and reading data permission is by organization prescribed.In simple terms, private There is chain can be for weak center's system, participating in node has stringent limitation and less.Such block chain more suitable for It is used inside particular organization.

Alliance's chain is then the block chain between publicly-owned chain and privately owned chain, it can be achieved that " part decentralization ".Alliance Each node usually has corresponding physical mechanism or tissue in chain；Network and composition benefit is added by authorization in participant Beneficial correlation alliance, it is common to safeguard the operation of block chain.

Whether publicly-owned chain, privately owned chain or alliance's chain may all provide the function of intelligent contract.Intelligence on block chain Contract is the contract that can be executed by transaction triggering on block catenary system.Intelligent contract can pass through the formal definition of code.

By taking ether mill as an example, user is supported to create in the network of ether mill and call the logic of some complexity, this is ether Mill is different from the ultimate challenge of bit coin block chain technology.Ether mill is ether mill void as the core of a programmable block chain Quasi- machine (EVM), each ether mill node can run EVM.EVM is the complete virtual machine of figure spirit, it means that can be with The logic of various complexity is realized by it.It is exactly to run on EVM that user, which issues in ether mill and call intelligent contract,.It is real On border, what virtual machine was directly run is virtual machine code (Virtual Machine bytecodes, lower abbreviation " bytecode ").It is deployed on block chain Intelligent contract can be the form of bytecode.

Such as shown in Fig. 1, Bob by one comprising create the transaction (Transaction) of intelligent contract information be sent to Too after the network of mill, the EVM of node 1 can execute this and trade and generate corresponding contract example.In 1 in figure " 0x68e12cf284 ... " represents the address of this contract, and what the data field of transaction saved can be bytecode, transaction To field is an empty account.After being reached an agreement between node by common recognition mechanism, this contract is successfully created, and subsequent user can To call this contract.

Contract creation after, on block chain occur a contract account corresponding with the intelligence contract, and possess one it is specific Address, contract code and account storage will be stored in the contract account.The behavior of intelligent contract is controlled by contract code, and The account storage (Storage) of intelligent contract then saves the state of contract.In other words, intelligent contract to produce on block chain The raw virtual account stored comprising contract code and account.

It is previously mentioned, the byte that can be the intelligence contract saved comprising creating the data field of transaction of intelligent contract Code.Bytecode is made of a series of byte, and each byte can identify an operation.It is more based on development efficiency, readability etc. From the aspect of, developer can not directly write bytecode, but select a high level language intelligence contract code.Example Such as, using high-level languages such as Solidity, Serpent, LLL language.For the intelligent contract using high level language Code can compile by compiler, generate the bytecode that can be deployed on block chain.

By taking Solidity language as an example, the contract write with it and class (Class) the very phase in Object-Oriented Programming Language Seemingly, a variety of members, including state variable, function, function modifier, event etc. can be stated in a contract.State variable It is the value being permanently stored in the account storage of intelligent contract, for saving the state of contract.

This specification be directed to it is a kind of build public good platform based on block chain, and by being disposed in block chain Intelligence contract relevant to public good project to promote the links such as the donations of public good project are handled and donations execute, Lai Tisheng automatically The solution of the transparency of public good project and the public to the degree of belief of public good project.

Realize when, the operator (such as charity) of public good project, can according to the project plan of public good project with And the specific implementation details of promotion of item, carry out developing intellectual resource contract, is stated at donations relevant to the public good in intelligent contract Logic is managed, and donations execute logic, the intelligent contract that exploitation is completed then is distributed to block chain and carries out intelligent contract deployment.

The management platform (such as trusteeship party of public good project) of public good project, can be by all portions in the form of intelligent contract The public good project of administration is pushed to the client of donor, is presented to donor in the form of bulleted list, so that donor It can carry out selection target public good project, from bulleted list to complete to offer.

After donor has selected the target public good project for being desired with donation, client can be according to the tax of donor Object is given to construct donations transaction, and the node device that the donations transaction of building is sent in block chain, to be invoked at block The intelligent contract corresponding with the target public good project disposed on chain.

And the node device in block chain can respond the donation transaction, be invoked at disposed on block chain with the target public affairs The donations processing logic stated in the corresponding intelligent contract of beneficial project, is transferred to sound in intelligent contract for the donations object of donor Bright donations trusteeship party, and when determining that the target public good project meets preset whip-round completion condition, it can further call The donations stated in the intelligence contract execute logic, by solicit contributions the donations object completed be transferred to stated in the intelligence contract with The target public good project is corresponding by donor.

Fig. 2 is referred to, Fig. 2 is a kind of process for public good donation method based on block chain that an exemplary embodiment provides Figure.As shown in Fig. 2, this method is applied to the node device in block chain, comprising the following steps:

Step 202, the donations for target public good project that donor initiates are received to trade；The donations transaction includes contributing Give object；

Step 204, it trades in response to the donations, calls publication corresponding with the target public good project on block chain Intelligent contract in the donations processing logic stated, the donations object is transferred to the donations support stated in the intelligent contract Guan Fang；

Step 206, when determining that the target public good project meets preset whip-round completion condition, further described in calling The donations stated in intelligent contract execute logic, by solicit contributions the donations object completed be transferred to stated in the intelligence contract with The target public good project is corresponding by donor.

Above-mentioned donations object may include contributor to the public good fund or public welfare forestry donated by contributor；Wherein, Above-mentioned public welfare forestry can be physical item, be also possible to virtual objects.Correspondingly, the whip-round object of above-mentioned public good project, it can To be public good fund, it is also possible to public welfare forestry.

For example, under a kind of whip-round scene shown, the donations object of the whip-round object and contributor of public good project, To be public good fund；In such a scenario, the operator of public good project can use donations trustship account and contribute to manage contributor The public good fund given, and after whip-round, the public good fund in trustship account will be donated, transferred accounts to by contributor's account；Or Person provides the charity account of service towards contributor.

For another example, under another whip-round scene shown, the whip-round object of public good project can be public welfare forestry, and offer The donations object of people's donations can be public good fund.The operator of public good project can use the public good fund of contributor's donations The public welfare forestry solicited contributions is needed to purchase, then offers the public welfare forestry of buying to by contributor.

1) public good project is disposed in the form of intelligent contract

In the present specification, the operator (for example can be charity) of public good project is initiating a public good project When, the detailed project plan and the project plan can be specified to promote related specific implementation details based on actual demand；

For example, detail involved in the project plan of public good project, may include the Project Introduction of public good project, it is public The whip-round period of beneficial project, the acquisition side of the public welfare forestry of whip-round and shopping list, the total value of the public good fund of whip-round, are offered The details of people, trusteeship party's account solicit contributions completion condition, solicit contributions termination condition, etc..

The operator of public good project, can be thin according to the project plan of public good project and the specific implementation of promotion of item Section, carrys out developing intellectual resource contract, and trusteeship party's account, the details by contributor of public good project are stated in intelligent contract； And execution logic relevant to the public good project.For example, above-mentioned execution logic, specifically can be the operator of public good project Execution function based on high-level language exploitation.

Wherein, it should be noted that the execution logic relevant to public good project stated in above-mentioned intelligent contract, usually It may include donations processing logic, and donations execute logic.

Above-mentioned donations processing logic is executed, the donations object that contributor donates can be transferred to and to be stated in intelligent contract Donate trusteeship party；Above-mentioned donations trusteeship party, in particular to the trusted third party for being responsible for the donations Object Management group that management is solicited contributions.

It executes above-mentioned donations and executes logic, the donations object that the whip-round for donating trusteeship party's management is completed can be transferred to intelligence Can state in contract by donor.

In a kind of embodiment shown, in the above-mentioned intelligent contract that the operator of public good project is developed, in addition to can To state other than above-mentioned donations processing logic and above-mentioned donations processing logic, can also state relevant to above-mentioned public good project to sentence Disconnected logic and donations rollback logic, etc..

Wherein, above-mentioned decision logic can handle after logic is finished in above-mentioned donations and trigger execution.Intelligent contract The decision logic can be further executed, judges the public good item after the donations object of contributor to be transferred to donations trusteeship party Whether mesh meets preset whip-round completion condition and solicits contributions termination condition.

Correspondingly, above-mentioned donations execute logic, above-mentioned decision logic can be being executed, judge that above-mentioned public good project meets It triggers and executes after preset whip-round completion condition.Above-mentioned donations rollback logic, can be on executing above-mentioned decision logic, judging It states after public good project meets preset whip-round termination condition and triggers execution.The donations rollback logic is executed, can be completed soliciting contributions Donations object be retracted into corresponding donor respectively.

Wherein, above-mentioned whip-round completes condition and solicits contributions termination condition, can be by the operator of public good project according to specific Demand is customized.

In a kind of embodiment shown, if the whip-round object of public good project is public welfare forestry, and contributor is donated Donations object be public good fund；Under this public good scene, since the operator of public good project finally needs to utilize to solicit contributions The public good fund arrived, to purchase corresponding public welfare forestry；Therefore, the above-mentioned intelligent contract that the operator of public good project is developed In, it can also include article buying side and the shopping list of public welfare forestry of statement.It wherein, can be in the shopping list Including public welfare forestry to be purchased, and unit price of procurement corresponding with public welfare forestry to be purchased.

Due under this public good scene, if statement buying side and corresponding do not purchased clearly in advance in intelligent contract It is single, it not only results in buying side and specific shopping list is not transparent enough, can also can not may give the public one due to charity A clearly specific effect expectation, causes the public discontented to the desired effect of public good project；

For example, the public may have objection to public welfare forestry procurement price, the specified buying side of charity can be queried and deposited In Tunneling etc.；Moreover, the period of public good project is usually all long, the procurement price of public welfare forestry may in the meantime It fluctuates, the case where overspending or never running out occurs in the public good fund that the public may query whip-round.

Therefore, charity is clear by the intelligent contract of public good project, stating buying side and corresponding buying in advance It is single, allow charity to give the public one clearly specific effect expectation, can further promote the transparent of public good project The degree of belief of degree and the public to charity.

Correspondingly, in such a scenario, condition is completed in above-mentioned whip-round specifically can be, within the preset whip-round period, turn The public good fund for moving to donations trusteeship party's account, reaches the procurement payment total value in above-mentioned shopping list；And above-mentioned whip-round Termination condition specifically may is that within the preset whip-round period, is transferred to the public good fund of donations trusteeship party's account, does not reach To the procurement payment total value in above-mentioned shopping list.

In the present specification, after completing the exploitation of above-mentioned intelligent contract, the operator of public good project can create one Transaction comprising the intelligence contract, and send the transaction on the management platform of public good project.

Wherein, it should be noted that the management platform of the public good project of this specification description specifically can be one and be based on The distributed pipes platform that block chain technology is built.It may include that several nodes as in block chain are set in the management platform Standby service equipment；For example, server.

After node device in block chain receives the transaction, the EVM of node device can execute the transaction, and set in node The common recognition mechanism carried between standby by block chain, after reaching an agreement to the execution of the transaction (i.e. transaction common recognition passes through), It will appear a contract account corresponding with the intelligence contract on block chain, intelligence contract deployment at this time is completed.

Wherein, it should be noted that common recognition mechanism used by above-mentioned block chain, in the present specification without especially limiting It is fixed；

For example, can prove (Proof of using such as proof of work (Proof of Work, POW) and equity Stake, POS) etc. needs contention book keeping operation power common recognition algorithm, such as practical Byzantine failure tolerance (Practical can also be used Byzantine Fault Tolerance, PBFT) etc., what the node that there is book keeping operation to weigh had been agreed upon before epicycle book keeping operation is total to Know algorithm.

2) public good project is promoted by way of calling intelligent contract

In the present specification, the management platform of public good project can be deployed in block in the form of intelligent contract for all Public good project on chain generates corresponding bulleted list, then the bulleted list of generation is pushed to the client of donor, to Donor is presented.And donor can be by the public good project list that presents in the user interface of viewing client-side, to select Corresponding target public good project is selected, to participate in public good project.

Fig. 3 is referred to, Fig. 3 is a kind of schematic diagram that public good project list is presented by client shown in this specification.

As shown in figure 3, by taking above-mentioned management platform is the management platform that public good books solicit contributions project as an example, charity can be with The public good books for disposing various demands in the management platform by way of disposing contract solicit contributions project；For example, shown in Fig. 3 It includes " whip-round of popular science category books " and " whip-round of history class books " etc. that public good books, which solicit contributions project,.Above-mentioned management platform can will be public The various public good books of beneficial mechanism deployment solicit contributions project, are presented to contributor by client in the form of bulleted list, so that Contributor can select the whip-round project desired to participate in above-mentioned user interface.

In the present specification, after donor has selected the target public good project for being desired with donation, client may be used also The details interface of the target public good project to be further presented to donor；It wherein, may include the mesh in the details interface The relevant informations for several alternative donations objects that mark public good project needs to solicit contributions, so that contributor is from the details interface The middle corresponding donations object of selection completes donations.

Fig. 4 is referred to, Fig. 4 is a kind of showing for details interface that public good project is presented by client shown in this specification It is intended to.

As shown in figure 4, still by taking above-mentioned management platform is the management platform that public good books solicit contributions project as an example, it is assumed that donor " whip-round of popular science category books " project shown in Fig. 3 is selected, client can further be presented this " popular science category books are raised at this time The details interface of tax " project；For example, above-mentioned details interface shown in Fig. 4 specifically can be one " popular science category customization book list " Interface shows the shopping list that intelligent contract is stated in advance to contributor in the interface, contributor is adopted above-mentioned Corresponding books are selected in purchase inventory, the tax of public good fund is then completed according to the unit price for the books stated in shopping list It gives.

In the present specification, the relevant information for the donations object that client can be donated according to donor, is contributed to construct The node device given transaction, and the donations transaction of building is sent in block chain, come be invoked at disposed on block chain with this The corresponding intelligent contract of target public good project.

For example, can specifically carry the conjunction of intelligent contract corresponding with the target public good project in the transaction when realizing About address, the function name of the execution function in the called intelligence contract, and the above-mentioned donations pair as call parameters The relevant information of elephant.

And the node device in block chain, after receiving the transaction, the EVM of the node device can execute the transaction, and The common recognition mechanism carried between node device by block chain after reaching an agreement to the execution of the transaction, calls the intelligence to close The donations stated in about handle logic, and the donations object in the transaction is transferred to the donations trustship stated in the intelligence contract Side.

For example, by taking the donations object of the donor is public good fund as an example, by calling the tax stated in the intelligence contract Processing logic is given, the public good fund in the transaction can be transferred to the donations trusteeship party account stated in the intelligence contract.

In a kind of embodiment shown, stated in the donations object in the transaction to be transferred to the intelligent contract Donations trusteeship party after, can further call the decision logic, judge whether the target public good project meets preset raise It contributes completion condition and solicits contributions termination condition；

For example, above-mentioned decision logic can be further still called so that the donations object of the donor is public good fund as an example, Judge that above-mentioned target public good project within the preset whip-round period, is transferred to the public good fund of above-mentioned donations trusteeship party account, is The no procurement payment total value reached in the above-mentioned shopping list stated in the intelligence contract；If so, showing the target public good item Mesh meets preset whip-round completion condition；(for example project alreadys exceed and solicits contributions the period) if not, shows the target public good project Meet preset whip-round termination condition.

On the one hand, it if it is confirmed that the target public good project meets preset whip-round completion condition, can further call It states the donations stated in intelligent contract and executes logic, the donations object completed will be solicited contributions be transferred to and state in above-mentioned intelligence contract It is corresponding by donor with the target public good project.

In a kind of embodiment shown, by taking the whip-round object of above-mentioned target public good project is public welfare forestry as an example, such as Fruit confirms that the target public good project meets preset whip-round completion condition, then can further call and state in above-mentioned intelligent contract Donations execute logic, the public good fund completed will be solicited contributions, sound in above-mentioned intelligent contract is transferred to by above-mentioned donations trusteeship party account Bright article buying side account, and the shopping list stated in the intelligence contract is also sent to above-mentioned article buying side；And it is somebody's turn to do The public good fund solicited contributions and completed can be used in article buying side, and public welfare forestry is purchased according to the shopping list, then will buying Public welfare forestry logistics transportation to by donor；Alternatively, giving the public welfare forestry logistics transportation of buying towards being provided by donor The charity of service.

Wherein, above-mentioned article buying side, specifically can be the manufacturer of above-mentioned public welfare forestry；That is, above-mentioned by calling Donations processing logic, the public good fund that can will solicit contributions completion are directly transferred to above-mentioned intelligence by above-mentioned donations trusteeship party account and close The manufacturer for the public welfare forestry stated in about.

Due to transferring accounts public good fund to third-party buying side, adopted by third-party buying Fang Zaixiang manufacturer Purchase, the public still may can query buying side, and there are Tunnelings；Therefore, it is transferred accounts by will directly solicit contributions the public good fund completed To the manufacturer of public welfare forestry, can be purchased to avoid public good fund is transferred to incredible third party, so as to most Big degree gives up query of the public to public good project.

Certainly, in practical applications, if the public good fund of above-mentioned target public good project, confirming the target public good item When mesh meets preset whip-round completion condition, the donations stated in above-mentioned intelligent contract can further be called to execute logic, it will Solicit contributions the public good fund completed be transferred to stated in above-mentioned intelligent contract with by donor's account；Alternatively, being offered towards this Side provides service side's account of service.

For example, can be transferred accounts directly by the medical expense of whip-round for soliciting contributions medical expense to the sufferer of financial difficulties To the personal account of the sufferer；Alternatively, can also transfer accounts directly by the medical expense of whip-round and provide medical treatment clothes to towards the sufferer The account of the medical institutions of business.

On the other hand, if it is confirmed that the target public good project meets preset whip-round termination condition, (for example public good project is not Solicited contributions within the defined whip-round period and arrive enough public good funds), it can further call the tax stated in above-mentioned intelligent contract Rollback logic is given, the donations object completed will be solicited contributions and be retracted into corresponding donor respectively.

For example, the donations for donor record, can carry out depositing card on block chain.In turn, rollback link is being donated, It can be recorded based on the donations for depositing card on block chain, after being checked and write off to the public good fund that whip-round obtains by pen, whip-round is obtained Public good fund original donor is returned to by pen.

In this way, donor can utmostly be avoided when target public good project terminates for some reason Loss.

In the present specification, the case mechanism based on intelligent contract calls in intelligent contract in the transaction by initiating After executing logic, intelligent contract would generally trigger corresponding event, and the event that intelligent contract triggers is stored in block chain On；

For example, by taking ether mill as an example, the event of intelligent contract triggering, it will usually which write-in transaction (calls that of intelligent contract Transaction) execution journal (log), then by execution journal storage to the exchange block receipt (receipt) set In.The data tree uses MPT (Merkle Patricia Tree) tree, has recorded the exchange and owns within a block The receipt of transaction, and the hash value of the tree root of the receipt tree is recorded in the exchange in the area of block as receipt root In build.

And the node device in block chain, the thing that by intelligent contract is triggered of the monitor log on block chain can be passed through Part makes further event response to the event listened to.

Wherein, specific event response logic corresponding to the further event response made to the event listened to, In the present specification without being particularly limited to.
