Processor in user's device will execute corresponding contract and work out program, such as step S307, including initial corresponding selection contract item
User interface, such as a kind of condition UI, system by this user interface require user input contract work out ginseng
Number, and receive the contract that interface generates whereby and work out parameter, such as step S309, forms a contract and work out content.
At this point, will require to use after the completion of treaty content in the case where the intelligent contract of the blocks chain such as ether mill makes a rule
Person pays expense with optional network specific digit digital cash (such as ether coin), and expense digs up mine the miner provided on the blocks chain such as ether mill
Excitation gold.And system still can require payout figure currency before contract starts to work out, this process program sequence of steps is simultaneously unlimited
Determine substantial technological feature.Then it is transmitted to contract server, with true after user agrees to payout figure currency such as step S311
Recognize digital token payment.While step, or within a certain period of time, it will be operated by software program in user's computer, or
It is operated by contract server, such as step S313, treaty content is compiled to form contract digital archives (binary file), such as walked
Rapid S315 generates the contract package that can be broadcast on block chain, and such as step S317, this package is published to area by contract server
On block chain, to wait the mining of each miner on block chain as a result, such as step S319.
Within a certain period of time, contract server will can receive mining as a result, being a contract address, such as step in practice
S321 after being received by server, is transmitted to user's device, informs contract address.Intelligent contract method for making and subscribing process flow operation exists
Between node on user's device, contract server and block chain, embodiment also can refer to intelligence contract system shown in Fig. 4
The two of the embodiment flow chart of binding method arrive wherein being shown as user 41, server 42 and the intermediate step S401 of block chain 43
The intelligent contract of S408 works out process.
Under this expression, user 41 operates user's device, such as personal computer, running gear, in user
A software program is run on device, embodiment is one user interface of initial, the option of formulation contract needed for being selected by user,
Once online server 42, contract options will be appended personal authentication's information, encryption data etc., transmit contract to server 42 and work out
The request (step S401) of service.
Server 42 is then by the software program initial user interface on user's device, such as the APP of running gear
Or web interface, it is desirable that input treaty content (step S402), such as token quantity, purposes, digital cash information (wallet position
Location, ether coin account etc.).After user 41 completes input, transmission treaty content and relevant authentication and safe information are (as used
Person's identification information) server 42 is arrived, and confirm publication contract (step S403).
At this point, server 42 can require payment token, it is desirable that user 2 provides digital cash account address, such as runs
Digital cash (step S404) on the block chain of ether mill.
If this is the fuel (gas) for activating intelligent contract on the block chain of ether mill by taking ether coin as an example, two kinds can be used
The account of type, first is that external account, the address message that saved by private key encryption and contract account, such as an operation obtain,
By contract code control.When paying ether coin, user sends payment message by digital signature, whenever contract account receives
When message, the code inside contract will be activated, and allow to read and write, to work out intelligent contract.
In this example, once user 41 sends the message (step S405) of confirmation payment to server 42, server 42 is compiled
Treaty content is translated, intelligent contract digital archives is formed, generates transaction code (transaction code), this is a kind of with number
The data packet (hash value) of signature, transaction code contain treaty content, user's identification information and payment information (token) etc., and
Contract (step S406) is issued on block chain 43, and waits the mining on block chain as a result, namely waiting a contract position
Location (step S407).When servomechanism 42 receives the mining on block chain 43 as a result, being in this instance exactly to generate new block (mine
Every dig to a successful block of works will obtain the reward of ether coin), the address of this contract is obtained, i.e., by this contract address
Notify the user 41 (step S408) of formulation contract.Once the account and digital currency payment that ensure to have unlock on block chain,
I.e. deployment is completed, and a contract will be worked out on block chain.
Later, contract address is announced on internet (such as community media) by user 41, interesting person can participate in closing
Together.After contract completes deployment, that is, it can refer to the process for using figure of one embodiment of the invention shown in Fig. 5, this legend process step
S501-S509 describes intelligent contract process for using.
As shown in figure 5, at the beginning, such as step S501, user successfully passes through intelligent contract system and is filled by user
The user interface set generates and obtains contract address, for another example step S503, and a certain number of tokens are transmitted to by user
Contract address, ticket that these tokens can be interested in for consumer admission ticket, allow to prove using the permission of special article,
Again after announcing contract address, such as step S505, start execution contract, that is, starts one coin program.
The consumer of participation contract, such as step S507, the contract item that user can be followed to be published on network social association
Part sends digital cash to contract address, and after a confirmed payment, such as step S509, token will be dispatched to by intelligent contract automatically
Consumer, in the digital cash wallet account including consumer.
For example, when user works out contract, which includes the meal coupon, the wallet address that transmit a certain number of tokens
And temporal information (termination of contract time limit), consumer can learn contract address from contract enactor, interesting person can be according to
Digital cash is transmitted according to wallet address, it, will be to send coin program that meal coupon is sent with charge free to the device of consumer after a confirmed payment
On, it can be the digital cash wallet account for being assigned to consumer.
Then, intelligent contract system provides the scheme for terminating (or claiming currency) intelligent contract, as shown in Figure 6 the present invention one
The stop intelligent contract and settlement process figure of embodiment.
When intelligent contract because condition meets or when user terminates, such as step S601, will stop sending coin program, such as with
For upper meal coupon, i.e. expiration of contract or token is used up, that is, is automatically stopped and is sent coin, and consumer payment digital cash is no longer received
Obtain meal coupon.At this moment, the user for working out contract can login contract server, such as step S603, it is desirable that claim the number received
Currency, such as ether coin.In the process, user generates the message of ping by the software program operated on user's device, passes
It is sent to contract address, such as step S605, server executes the instruction that contract is claimed, and contract is just valuable by the digital cash received etc.
Contract coin, i.e. outturn currency is transmitted in the digital cash account of user, such as step S607.
Once intelligent contract is successfully worked out, an address is occupied on block chain, at permanent record, i.e., not
It must delete.However, for contract, it is possible to must break one's promise under specific circumstances, herein the scheme of intelligent contract method for making and subscribing
In, it can be using the flow chart of the intelligent contract of cancellation of one embodiment of the invention as shown in Figure 7.
In condition, since contract formulation is all revealed intelligent contract system through the invention, such as step S701 institute
It states, contract server provides user's block chain account and digital cash wallet address, user can pass through intelligence whereby
User's account that energy contract system provides executes contract deregistration procedure.
Then such as step S703, contract server are closed by the user interface prompt intelligence operated on user's device
Same several Xiang Gongneng, including contract nullify function, nullify function once executing this contract, such as step S705, contract server is connect
The function of receiving the cancellation of bill treaty generated by user interface selects, and software program generates a contract log-out instruction, such as step
S707, contract server are the log-out instruction for obtaining user's transmission, later such as step S709, after being issued on block chain,
After mining is just waited for as a result, being obtained miner's mining result, such as step S711, contract servomechanism and user's confirmation are nullified and are closed
Together.
The present invention also discloses the computer-readable storage device in contract server, wherein being stored in contract server
