In addition, the of the present invention first intelligent contract, the second intelligent contract and third intelligence contract be not merely to
It is substantially exactly the intelligent contract on block chain with the noun distinguishing intelligent contract in embodiment and defining.For example, first
It is used when an intelligent contract that intelligent contract is that event agent's intelligence contract only executes；Second intelligent contract is event agent's intelligence
Contract also additionally executes used when other intelligent contracts other than the first intelligent contract；Third intelligence contract is then series winding multilayer
Event agent's intelligence contract when it is used.
Cooperation schema is described further the event connection system and method for intelligent contract of the invention below, please first joins
Fig. 1 is read, Fig. 1 is that the event of the intelligent contract of the present invention connects the system block diagram of system, this system includes: initial module 110 connects
Connection module 120, transaction modules 130 and execution module 140.Wherein, initial module 110 at the beginning, to issue event in advance
Intelligent contract, the first intelligent contract (such as: renting room intelligence contract) and event agent's intelligence contract are transmitted to block chain, the thing
Part, which acts on behalf of intelligent contract, has event agent's intelligence contract address, and includes interface function to allow event to transmit intelligent contract
Transmission event.In actual implementation, the event transmits intelligent contract and refers to the intelligent contract that can transmit event (Event), such as:
Application program intelligence contract, digital cash intelligence contract etc., for example, digital cash intelligence contract be to digital cash into
The intelligent contract of row processing, comprising setting publisher's permission of digital cash, limiting and only issue digital cash, verifying by publisher
The processing such as digital cash publisher and transmission digital cash, wherein including by submitting when sending digital cash: originating party address,
The event of debit address and number of transaction.Described first intelligent contract is another intelligent contract on block chain, such as: rent room
Intelligent contract, intelligent contract of hiring a car, rent book intelligence contract etc..It is then via interface letter as event agent's intelligence contract
Number receives the event that intelligent contract is transmitted from event, and has the permission that the first intelligent contract is executed according to this event.It is special
Not it is noted that initial module 110 at the beginning, can also issue the second intelligent contract (such as: renting room and insure intelligent contract)
It is held respectively so that execution module 140 is after event agent's intelligence contract receives event according to the event received in block chain
The first transaction function (such as: renting room function) in the intelligent contract of row first, and execute in the described second intelligent contract the
Two transaction functions (such as: purchase insurance function), these transaction function stands the programmed logic of transaction content.In addition, in reality
On border is implemented, event agent's intelligence contract can also execute the corresponding second intelligent contract according to different debit addresses, later will
Cooperation schema elaborates to this part.
Link block 120 transmits the registration function of intelligent contract to execute event, and when the ground of registration function transmitting
When location is event agent's intelligence contract address, setting event transmits intelligent contract and transmits event to event agent by interface function
Intelligent contract, and the proxy function of the first intelligent contract is executed, and intelligently close according to the event agent that this proxy function is transmitted
About address makes event agent's intelligence contract have the permission for executing the first intelligent contract.In actual implementation, when registration function passes
The address passed be preset value (such as: when 0x0), remove the connection that event transmits intelligent contract and event agent's contract, work as transmitting
Address be event agent's contract address (such as: when 0x4d9e6d999e113b52ce96aee86a42f3279c115a73),
The parameter of event agent's contract address write-in declaration is referred to as to register, at this point, establishing event transmits intelligent contract and thing
The connection of part correspondent contract.The connection refers to enables indirect relevant different intelligent contract to transmit letter by function call
Breath, for example, event transmits intelligent contract and gives event agent's contract by interface function transmitting event, and event agent's contract
Then by the proxy function of the first intelligent contract, event agent's intelligence contract address is passed into the first intelligent contract, to incite somebody to action
Event agent's intelligence contract address is set as agent, or when the first intelligent contract is to rent room intelligence contract, event
Originating party address is set as tenant (tenant) by correspondent contract by the rent room function of the first intelligent contract, and can be according to block when
Stamp (Block Time Stamp) is set at the beginning of tenant charters and the end time.
Transaction modules 130 transmit the transmission function of intelligent contract when executing transaction, to execute event, such as: in thing
When the intelligent contract of part transmitting is digital cash intelligence contract, hair money address is treated as in the originating party address, the debit address is treated as
Gathering address and the number of transaction treat as transaction amount, and transaction amount can be sent to gathering address by executing transmission function,
And include via interface function transmitting: the event of hair money address, gathering address and transaction amount to event agent's intelligence contract.
In actual implementation, transaction modules 130 can first judge whether the remaining sum for sending out money address is less than transaction amount, if so, returning not
It executes transaction and does not also transmit event, if it is not, the remaining sum for sending out money address is then subtracted transaction amount, and by the remaining sum for address of collecting money
In addition transaction amount, then transmits event again.
Execution module 140 executes the to after event agent's intelligence contract receives event, according to the event received
The first transaction function in one intelligent contract.In actual implementation, the first intelligent contract only allows agent and owner to execute,
It passes through address to determine whether being agent or owner.Due in link block 120, having passed through the first intelligent contract
Proxy function transmit event agent's intelligence contract address, event agent's intelligence contract address is set as acting on behalf of by this mode
People hands over so the first intelligent contract allows event agent's intelligence contract to execute first in the first intelligent contract according to the event
Easy function.Assuming that the first intelligent contract is to rent room intelligence contract, it includes the first transaction function may include: rent room function, move back
Room function etc..
Then, referring to Fig. 2, Fig. 2 is the method flow diagram of the event connection method of the intelligent contract of the present invention, step packet
It includes: at the beginning, preparatory publication event transmitting intelligence contract, the first intelligent contract and event agent's intelligence contract to block chain,
Wherein, event agent's intelligence contract has event agent's intelligence contract address, and includes interface function to allow event to transmit
Intelligent contract transmits event (step 210)；Execution event transmits the registration function of intelligent contract, and when registration function transmitting
When address is event agent's intelligence contract address, setting event transmits intelligent contract and transmits event to event generation by interface function
Reason energy contract, and the proxy function of the first intelligent contract is executed, and intelligently close according to the event agent that proxy function is transmitted
About address makes event agent's intelligence contract have the permission (step 220) for executing the first intelligent contract；When executing transaction, hold
The transmission function that part transmits intelligent contract is acted, number of transaction is sent to debit address, and transmit and wrap via interface function
The event of address containing originating party, debit address and number of transaction is to event agent's intelligence contract (step 230)；In event agent's intelligence
After contract receives event, the first transaction function (step 240) in the first intelligent contract is executed according to the event received.It is logical
Cross above-mentioned steps, can by being transmitted between intelligent contract and the first intelligent contract for receiving event in the event of transmission event,
Increasing event agent's intelligence contract with interface function, the event that provides transmits intelligent contract and transmits event with interface function, with
And event agent's intelligence contract address is transmitted by the proxy function of the first intelligent contract, event agent's intelligence contract is set as
Therefore permission with the intelligent contract of execution first when the event of design transmits intelligent contract, learns the first intelligence without preparatory
The content of contract, and can make to send and receive event and be completed in the same block of block chain.
Cooperation Fig. 3 to Fig. 5 is carried out as described below by way of examples below, is please using this hair referring initially to Fig. 3, Fig. 3
The bright schematic diagram in the situation for renting room.Assuming that the first intelligent contract is to rent room intelligence contract, if wanting under the situation for renting room
It buys again and rents room insurance, then the second intelligent contract is and rents room to insure intelligent contract.Described first intelligent contract and the second intelligence
Contract can pass through source code (311,312) Lai Shixian as schematically shown in Figure 3.At the beginning, event can be transmitted intelligent contract,
First intelligent contract, event agent's intelligence contract and the second intelligent contract publication are in block chain, wherein publication event agent's intelligence
Contract can obtain event and transmit intelligent contract entity, so as to time call registration function, such as " registerEventProxy " and band
Enter an address, when this address is event agent's intelligence contract address, that is, represents registered events and act on behalf of intelligent contract.Then,
The first intelligent contract entity is obtained, so as to Call Agent function " setDelegate " and brings event agent's intelligence contract address into,
So that event agent's intelligence contract is set as agent, that is to say, that event agent's intelligence contract, which has, executes first intelligence
The permission of energy contract.Next, from originating party address (hair money side；Tenant) transaction of block chain is sent, it sends and rents the room amount of money to debit
Address (beneficiary；House owner), and after event agent's intelligence contract receives the event that event transmits intelligent contract transmission, according to connecing
This event for receiving executes the first transaction function in the first intelligent contract, rents room insurance if to buy again, then executes the again
The second transaction function in two intelligent contracts, by taking the situation for renting room as an example, the first transaction function is to rent room function " rent "；The
Two transaction functions are to buy insurance function " RentalHomeInsurance ".In the example for renting room situation, in addition to executing the
Except the second transaction function in two intelligent contracts, the entity on behalf purchase insurance that can also increase one second intelligent contract newly is closed
About, and the constructor (Constructor) in the second intelligent contract is executed to change its parameter state.If in this way,
Want extended function or practice other situations (such as: renting book, hire a car etc.), it is only necessary to establish corresponding event agent's intelligence contract and
First intelligent contract, and new event agent's intelligence contract address strap incoming event is transmitted intelligent contract by time call registration function,
So that event is transmitted intelligent contract and be directed toward new event agent's intelligence contract, for example, assuming that the block for being 100 in number, former
Originally practice of event agent's intelligence contract on address " 0x0001 " is used.But the version of later event agent's intelligence contract
This upgrading, therefore the block for being 150 in number issues new version, obtained new address is " 0x0002 ", can at this time be led to
Registration function is crossed to register new event agent's intelligence contract, it is assumed that block chain caused by registration function, which is traded in number, is
Block chain is included into when 160 block, then event agent's intelligence contract, in the block that number is 160, address quilt dynamic is more
It is newly " 0x0002 " in other words, to pass through the variable event agent's intelligence contract being more directed to of registration function.
As schematically shown in Figure 4, Fig. 4 is the schematic diagram that the data flow of intelligent contract is connected using the present invention.Firstly, on Fig. 4
Fang Chengxian most basic connection type, it may be assumed that event transmitting intelligence and about 410, event agent intelligence and about 420 and the first intelligence are closed
About 430.Wherein, event transmitting intelligence and about 410 via event agent intelligence and about 420 interface function (such as:
It proxySentEvent), is digital goods with event transmitting intelligence and about 410 by event transmission to event agent's intelligence and about 420
For coin intelligence contract, hair money address, the gathering data such as address and transaction amount to event agent's intelligence and about 420 will be brought into；
Event agent's intelligence and about 420 the first intelligence of calling and about 430 functions, to change the first intelligence and about 430 corresponding each
Parameter state.Especially it is noted that in different use situations, with different event agent's intelligence and about 420 and first
Intelligence and about 430, for example, in the case where renting room situation, event agent's intelligence and about 420 practices " renting room " and " purchase is insured "
Logic, the first intelligence rent room intelligence contract with about 430, provide and rent room function (such as: rent) for calling and changing rent
The parameter state of room intelligence contract, for example, changing the parameter states such as tenant address, time started and end time.In reality
In implementation, event agent's intelligence and about 420 is succession (Inheritance) one only with the intelligent contract of interface function, and
And to override former interface function based on the interface function of different setting designings, and then generate event agent's intelligence of corresponding different situations
It can be with about 420.
Then, event agent's intelligence and about 420 is then presented below Fig. 4 can be performed simultaneously multiple intelligent contracts (that is: the
One intelligence and about 430 and second intelligence and about 440a~440n) connection type, in actual implementation, it is assumed that second intelligence close
About 440a is to rent room to insure intelligent contract, and event agent's intelligence and about 420 can pass through instruction " new
RentalHomeInsurance () " generates new intelligent contract entity.In addition, it is previously noted that event agent's intelligence contract also
The corresponding second intelligent contract can be executed according to different debit addresses.By taking the connection type below Fig. 4 as an example, it is assumed that debit
Location is " 0x00001 ", executes the second intelligence and about 440a；Assuming that debit address is " 0x00002 ", the second intelligent contract is executed
440b, and so on, it can be performed to the second intelligence and about 440n.In other words, event agent's intelligence contract can be according to difference
Payee define different event handling logics.
As schematically shown in Figure 5, Fig. 5 is the schematic diagram using present invention connection multilayer event agent intelligence contract.In practical reality
Shi Shang, event agent's intelligence contract may include father event agent intelligence and about 510 and subevent act on behalf of intelligent contract (511,
512), the father event agent intelligence and about 510 receives the event that event transmits intelligence and about 410 transmission by interface function,
Each subevent acts on behalf of intelligent contract (511,512) and is inherited from father event agent intelligence and about 510, and corresponding with executing
The permission of third intelligence contract (such as: renting book intelligence contract, rent room intelligence contract and insure intelligent contract etc.) is with Fig. 5
Example, subevent agency's intelligence and about 511 have the permission for executing and renting book intelligence and about 521；Subevent agency's intelligence and about 512 tools
Have execute rent room intelligence and about 522 and insurance intelligence and about 523 permissions, similarly, these third intelligence contracts are equally respective
With corresponding proxy function, to transmit the address that intelligent contract (511,512) is acted on behalf of in subevent, close subevent agency's intelligence
About (511,512) have the permission for executing third intelligence contract.
In summary, it is known that the difference between the present invention and the prior art is by transmitting intelligence in the event of transmission event
It can increase event agent's intelligence contract with interface function between contract and the first intelligent contract of reception event, thing is provided
Part transmits intelligent contract and transmits event with interface function, and transmits event agent's intelligence by the proxy function of the first intelligent contract
Event agent's intelligence contract is set as with the permission for executing the first intelligent contract, therefore, in design event by energy contract address
When transmitting intelligent contract, without learning the content of the first intelligent contract in advance, and it can make to send and receive event in block
It is completed in the same block of chain, can solve the problems of prior art by this technological means, and then reach raising
The design flexibility of intelligent contract and the technical effect of transaction security.
Although as above with embodiment above-mentioned explanation, however, it is not to limit the invention, any institute of the present invention by the present invention
