Detailed Description
In order to better understand the technical solutions, the technical solutions of the embodiments of the present specification are described in detail below with reference to the drawings and specific embodiments, and it should be understood that the specific features of the embodiments and embodiments of the present specification are detailed descriptions of the technical solutions of the embodiments of the present specification, and are not limitations of the technical solutions of the present specification, and the technical features of the embodiments and embodiments of the present specification may be combined with each other without conflict.
In a first aspect, as shown in fig. 1, an embodiment of the present specification provides a smart contract-based collection system, which includes a plurality of user terminals, where the plurality of user terminals include a contract creation terminal 100 and at least one contract participation terminal 200, and includes:
the contract creating terminal 100 is configured to create a charge share collecting contract in the blockchain 300, acquire a contract address of the charge share collecting contract, and send the contract address to each of the at least one contract participating terminal 200;
each of the plurality of user terminals is configured to acquire the contract address, download the charge sharing charging contract from the contract address, run the charge sharing charging contract, automatically execute the charge sharing charging contract locally, and pay the amount of the contract in the charge sharing charging contract.
In the embodiment of the present specification, the contract creation terminal 100 may be any one of the plurality of user terminals; further, the cost is shared by the contracts of collection, namely AA contracts of collection.
In this embodiment of the present specification, when creating the expense share collecting contract, the contract creating terminal 100 first needs to obtain item data corresponding to the expense share collecting contract, where the item data at least includes a commonly involved item and a payout amount; the charge share collection contract is then created in blockchain 300 based on the project data.
Of course, the amount of money to be paid by each terminal may be limited in creating the charge share receiving contract, and thus, the maximum amount of money to be paid by each terminal may be set. Wherein, the project data can also comprise data of the source of the project participated in together, the time of the project participated in together and the like.
In this embodiment of the present specification, when the contract creation terminal 100 creates the charge share collecting contract, the private key of the contract creation terminal 100 needs to be used to sign the charge share collecting contract.
In this embodiment of the present specification, the contract creation terminal 100 creates the charge share collecting contract, which specifically includes:
and setting a contract main body and contract terms of the charge sharing collection contract, wherein the contract main body is a payment account of each of the plurality of user terminals, the contract terms comprise response conditions and response rules, the response conditions comprise credit-granting cross-link payment behaviors, and the response rules comprise that collection is initiated to each of the plurality of user terminals after the transaction amount is shared.
In this embodiment of the present specification, in the process of creating the expense equalizing charge contract, the contract creating terminal 100 further needs to set a charge account number of the expense equalizing charge contract, where the charge account number is a payment account of any one of the plurality of user terminals.
In this embodiment, the payment account may be represented by a key and a unique address, where the unique address may be a hash value of the elliptic curve cryptography public key used by the blockchain 300. .
Specifically, the response condition includes a credited cross-chain payment behavior, and the credited cross-chain payment behavior is used for crediting a payment behavior in the charge share agreement so that after the charge share agreement is established, the user terminal can automatically deduct money from an account corresponding to the user terminal without being credited again through the response condition and the response rule, thereby prompting the charge share agreement to be automatically executed.
In this embodiment of the present specification, when each of the plurality of user terminals runs the charge share collecting contract, it is necessary to write a payment account of the terminal into the charge share collecting contract, and then sign the charge share collecting contract written into the payment account using a private key of the terminal.
In this embodiment of the present specification, in the process of paying the agreed amount in the charge share agreement at each of the plurality of user terminals, a relay technology may be used to exchange values outside and inside the block chain 300 through a third-party connector, so as to realize the payment of the agreed amount in the charge share agreement, where the relay technology may be a Po l kadot relay technology.
Specifically, since the first token (token) circulating in the blockchain 300 is generally used for conducting the transaction in the blockchain 300, and the transaction money is generally required to be conducted in the actual transaction process outside the blockchain, wherein the transaction money includes the legal money and other tokens, the first token is used in the charge share collection contract, the deduction is the transaction money when the charge share collection contract is used for conducting the deduction, and the value exchange between the outside and the inside of the blockchain 300 through the third-party connector is required to realize the payment of the agreed amount in the charge share collection contract.
For example, the total amount written in the charge share agreement is 20token, and 20token corresponds to 200 french coins, so when charging in the charge share agreement, if 5token corresponds to the first terminal, and according to the conversion relationship between token and french coin, the charge share agreement is about 5 × (200/20) to 50 french coins in the account corresponding to the first terminal.
Specifically, the third-party connector is a connector provided by a third-party payment mechanism and used for providing payment certificates for each terminal in the plurality of user terminals, and the whole process comprises the following steps that firstly, each terminal uses the payment function provided by the third payment mechanism to pay and uses the private key of the terminal to sign a payment receipt; secondly, the third party payment mechanism receives the payment receipt and generates a payment voucher; and after the payment voucher is detected to exist, automatically triggering the expense sharing collection contract, then controlling the expense sharing collection contract to locally operate, and automatically completing deduction.
In this embodiment of the present specification, after downloading the cost equalizing charge contract from the contract address, each of the plurality of user terminals needs to sign the cost equalizing charge contract by using a private key corresponding to each of the plurality of user terminals in the process of running the cost equalizing charge contract. Therefore, each terminal carries out private key signature on the charge sharing contract, the charge sharing contract is forced on the basis of the private key signature, the response condition of the contract terms in the charge sharing contract comprises the chain-crossing payment behavior of credit authorization, the payment behavior in the charge sharing contract is trusted, and therefore automatic charging can be carried out by utilizing the contract rule in the charge sharing contract.
In the embodiment of the specification, the charge sharing collection contract belongs to an intelligent contract, and the intelligent contract is a computer transaction protocol for executing contract terms and is an important component of the block chain 2.0. AA collection based on smart contracts is a formula for participants to joint payment behavior that once signed can not be tampered with, while being exposed over the network. The automatic execution of the collection is triggered after the occurrence of the expenditure which the participants should share, without the repeated confirmation of the participants, thus ensuring the collection of the full amount; and in the execution process of the collection contract, automatic deduction can be carried out without the need of reconfirming by the participant, and compared with the active deduction in the prior art, collection efficiency can be effectively improved, so that user experience is better.
In this embodiment, each of the plurality of user terminals may automatically execute the charge share charging contract locally after running the charge share charging contract.
For example, if the at least one participant terminal 200 includes a smartphone B1, a smartphone B2, and a smartphone B3, the contract creation terminal 100 initiates the AA collection contract, discloses the content of the AA collection contract, and sends a contract address to B1, B2, and B3; b1 downloads the AA collection contract from the contract address after the contract address is received by B1, runs the AA collection contract, writes the payment account of B1 into the AA collection contract during running the AA collection contract, and then signs the AA collection contract written with the payment account of B1 using the private key of B1, so that B1 becomes a contract participant of the AA collection contract; after acquiring the contract address, the contract creation terminals 100, B2 and B2 execute the same operation as that of B1, and all become contract participants of the AA collection contract; thus, the participants of the AA collection contract are enabled to create 4 terminals, terminal 100, B1, B2 and B3, for the contract.
If the content of the AA collection contract is a dinner group, the total amount is 50 tokens, and one token corresponds to 10 french coins, then according to a response rule in the AA collection contract, the total amount of 50 tokens is shared by the 4 terminals, so that the french coin corresponding to each terminal is determined to be 50 × 10/4 ═ 125, then according to the AA collection contract, collection is performed to each terminal, the collection amount is french coin 125, that is, the french coin 125 is deducted from the payment account of each of the 4 terminals, namely the contract creation terminal 100, B1, B2 and B3.
Further, if the charge account number set in the AA charge contract is the payment account of B1, the deduction from the payment account of each of the 4 terminals is placed into the payment account of B1, and 125 × 4 — 500 french coins are placed into the payment account of B1. Therefore, after each of the plurality of user terminals runs the expense sharing collection contract, the deduction can be automatically completed through the expense sharing collection contract, so that the collection efficiency can be improved under the condition of ensuring the full-amount collection, and the user experience is better.
