Modern smart contracts are first implemented on ETH, and the ETH public chain and EVM jointly ensure the operation of the contract. At present, there are also preliminary references to smart contracts on some public chains (ETH, EOS). These contracts are all running in the public chain, using the public chain as the carrier, such as relatively elementary games and exchanges. However, due to its own limitations, there is still a big gap from the application in all aspects of real life, and it is difficult to use in real life. In addition, most of the tradable smart contracts are limited by the speed of the public chain platform itself, and the speed is not high. Although centralized transactions are fast, they have the problems of unsupervised and low security.

Based on the above-mentioned terminal hardware structure, various embodiments of the present application are proposed.

In an embodiment of the present application, the present application provides a smart contract system, the smart contract system includes:

Mining contracts and trading contracts.

Among them, the mining contract is used to allocate the corresponding rights and interests according to the contribution of each application node connected to the smart contract system;

The transaction contract is used to perform transactions and arbitration services for exchanges connected to the smart contract system.

In a nutshell, a smart contract refers to a commitment agreement that is defined and automatically executed by a computer program. Among them, the mining contract in this application is different from the current mining mechanism (relying solely on power consumption and computing power) in that the mining contract in this application is based on the contributions of alliances, communities, funds, ecological malls, industrial services, etc. Mining to obtain corresponding rights and interests. The contribution degree can more directly and effectively reflect the contribution of each application node to the entire ecology, instead of simply judging based on power loss. Application nodes such as communities, e-commerce services, industrial platforms, etc., because different application nodes have different divisions of labor in the overall ecology, they do not all need to consume electricity to compete for computing power. Different application nodes are based on their actual requirements for public chain platforms. The beneficial work can obtain the corresponding corresponding contribution degree, and then obtain the rights and interests through the corresponding contribution degrees. The rights and interests in different scenarios can be uniformly converted into the corresponding WID in the public chain. The transaction contract can also be called a transaction management contract. The main function of the contract is to conduct transactions, management, query, arbitration and other operations for OTC transactions in the decentralized exchange. When the rights and interests including WID need to be traded, The transaction process is managed according to the transaction contract to complete the transaction, management, query and arbitration process of the transaction. The exchange can be the W-CBEx exchange or other exchanges that meet the contract requirements. Referring to Figure 2, the smart contract system includes mining contracts and transaction contracts, and the smart contract system is connected with exchanges, application nodes and public chains.

In another embodiment, the mining contract allocates corresponding rights and interests according to the contribution of each of the application nodes, and conducts cross-chain communication with the public chain so that the public chain generates corresponding rights and interests. That is, the corresponding contribution generation rules can be determined by the type of application nodes, corresponding rights and interests in different scenarios can be allocated, and the generated rights and interests-related information can be sent to the public chain through cross-chain communication, so that the public chain can generate corresponding rights and interests.

In another embodiment of the smart contract system, the transaction contract can run on the contract chain of the side chain of the public chain and adopts the WBFT consensus protocol based on BFT, that is, the transaction contract is not located on the public chain and does not belong to the exchange. Rewritten by a third party, it is more secure, and because it is based on BFT, it will be faster.

Among them, WID is used as a general interest in the public chain. In different application scenarios, different application nodes can generate different rights and interests. At the same time, WID is a common interest in the public chain. The rights and interests in different application scenarios can use WID as a standard in the transaction process to complete the corresponding transaction process.

This application also proposes a smart contract management method.

3, in the first embodiment of the smart contract management method, the smart contract management method is based on the smart contract system, and the method includes:

Step S10, obtaining the contribution degree of the application node connected to the smart contract system;

Application nodes include: alliances, development communities, promotion communities, e-commerce services, industrial platforms, etc. The contribution degree is obtained by different application nodes according to the work that is beneficial to the entire platform. For different application nodes, the contribution degree is obtained. standards are different. For each node in the industrial chain platform, the corresponding contribution can be obtained by completing the beneficial work corresponding to the platform. At the same time, the mining contract obtains the contribution of each application node, and then determines the corresponding equity distribution according to the contribution.

Step S20, calculating the equity of the application node according to the contribution degree and the mining contract;

The mining contract calculates the rights and interests of each application node according to the contribution degree of each application node. Different from the traditional power consumption competition, when obtaining the corresponding rights and interests according to the contribution degree, the mining contract first obtains the contribution degree of each application node. Then, according to the contribution of each application node, the corresponding equity is calculated and distributed to each application node.

Step S30, sending the calculated rights and interests results to a public chain connected to the smart contract system through a cross-chain protocol, so that the public chain generates the rights and interests;

After each application node needs to obtain the corresponding rights and interests according to the contribution degree, according to the cross-chain protocol, the calculated rights and interests results are sent to the public chain, and the public chain allocates the corresponding rights and interests to the corresponding application nodes and stores them according to the calculated rights and interests result information. into the account of the corresponding application node. Among them, the general rights and interests in the public chain are WID, that is, the rights and interests in different application scenarios can be converted into WID according to a certain conversion relationship. During the transaction process, the conversion between different rights and interests and WID is determined through the exchange and trading contract. The ratio, that is, in different transactions, the conversion ratio will be dynamically adjusted. Mining generates rights and interests according to the degree of contribution and links the generation of rights and interests with industrial applications, and the data information flow between industry chain platforms can also be carried by WID. Then the intrinsic value of the corresponding WID will also be higher, which will stimulate the application nodes to increase their contribution to mining, thus forming a benign positive feedback, so that each application node in the platform can actively participate in the construction of the platform.

Step S40, when receiving the transaction request for the rights and interests, complete the transaction operation according to the transaction contract;

After the application node obtains the corresponding rights and interests, it can conduct transactions according to the rights and interests in its own account, and the main function of the transaction contract is to provide operations such as transaction, management, query, arbitration, etc. for OTC transactions in the exchange. At the same time, the transaction contract runs on the contract chain of the side chain of the public chain, which is independent of the public chain and will not be easily rewritten by others, making it more secure. The transaction management contract can receive the lock-up request from the exchange, and then lock the rights and interests of the corresponding application node in the public chain accordingly. If the exchange and the buyer and seller have no objection to the transaction, the exchange will report to the transaction contract. Send the transaction confirmation information. When the transaction confirmation information is received, the cross-chain transfer operation will be completed according to the previous lock-up information. If there is any objection, the exchange will arbitrate the transaction, and the exchange will combine the transaction arbitration confirmation information with multiple The signature is sent to the transaction contract, and then the transaction contract can perform cross-chain transfer based on the arbitration confirmation information and multi-signature information, that is, transfer the locked rights to the seller or re-transfer back to the buyer.

In this embodiment, the contribution degree of the application nodes connected to the smart contract system is obtained; the rights and interests of each application node are calculated according to the contribution degree and the mining contract; The calculated rights and interests results are sent to the public chain connected to the smart contract system, so that the public chain generates the rights and interests; when a transaction request for the rights and interests is received, the transaction operation is completed according to the transaction contract. Through the mining contract and transaction contract in the smart contract, various rights and interests, including the generation and transaction of WID in the main chain, are managed, put into the same contract system, and the entire ecological chain is formed into a closed loop that can be implemented. . At the same time, the corresponding rights and interests are allocated to each application node according to the contribution degree, so that each application node can truly cooperate with each other in the same ecosystem.

Further, on the basis of the above-mentioned embodiments of the smart contract management method of the present application, a second embodiment of the smart contract management method is provided. In the second embodiment,

Before step S10, it includes:

Step A1, obtaining the node type of the application node;

Common application node types include: alliances, development communities, industry nodes, etc. The alliance generally includes financial institutions, and the development community includes members who develop functions for the application platform. Industrial nodes can include various nodes that use the application platform for practical applications, such as e-commerce enterprise nodes, data nodes, resource nodes, information nodes, etc. .

Step A2, according to the node type, determine the contribution degree generation rule of the application node;

For different application nodes, because they play different roles in this industry chain platform and undertake different tasks, the rules for obtaining contribution degrees are not exactly the same. It is not limited to the traditional acquisition of corresponding rights and interests based on the power consumption of computing power. For example, for the application node of the alliance type, the alliance node includes banks, funds, etc., which can provide services such as payment services, supervision and certification. Its contribution to obtain corresponding rights and interests. For community-type application nodes, community members can make their own contributions to the entire platform, such as developing and maintaining the public chain platform, putting forward good construction suggestions, etc., and they can obtain the contribution degree and obtain the corresponding rights and interests according to the contribution degree. For application nodes that are industrial nodes, such as e-commerce enterprise nodes, data nodes, resource nodes, information nodes, etc., various work contribution behaviors in the nodes, such as e-commerce dividend profit output, data upload, value analysis, information confirmation, etc. Corresponding contribution can be obtained to obtain corresponding benefits. The corresponding rights and interests are obtained through the contribution degree, including the WID in the public chain, and the WID is linked to the industrial application of each application node, and the data information flow between the industrial chain platforms can also be carried by the WID. Then the intrinsic value of the corresponding WID will be higher, thus stimulating the application nodes to increase their contribution to mining, forming a benign positive feedback.

Obtain the work results of the application nodes connected to the smart contract system, that is, the corresponding work completion status. Through the previous contribution generation rules, it is judged that the work results of each application node match the effective work of the application type, that is, the work that is beneficial to the industry chain, such as the corresponding payment or supervision work in the application node of the alliance type, for the development type The application node can be the development work for industrial applications. After the effective work of each application node is counted, the contribution of each node is allocated according to the effective work.

Among them, WID is used as a general interest in the public chain. The more users use WID, the corresponding developers and builders will work harder to develop some communities and applications that use WID. Similarly, this will prompt other application nodes to use WID more frequently, which will make WID again The value increases, which in turn promotes the development and use of corresponding WID applications and communities again, forming a corresponding positive cycle.

In this embodiment, different rights, including WIDs, are generated for different application nodes according to the contribution degree. At the same time, for different types of application nodes, the corresponding digital currency is not only obtained by relying on the computing power of power loss, but also the industrial chain can be realized. application of smart contracts.

Further, referring to FIG. 3 and FIG. 4 , on the basis of the above-mentioned embodiments of the smart contract management method of the present application, a third embodiment of the smart contract management method is provided. In the third embodiment,

Step S40 includes:

Step S41, when a transaction request for the rights and interests is received, acquire the lock-up information in the transaction request;

The exchange generates corresponding transaction information according to the transactions between buyers and sellers, and at the same time sends a transaction request to the transaction contract according to the transaction information. The transaction request includes the lock-up of the corresponding rights and interests of the seller to ensure that this part of the rights and interests cannot be traded temporarily.

Step S42, sending cross-chain lock-up information to the public chain according to the lock-up information, so that the public chain performs cross-chain lock-up;

At the same time, because the transaction contract runs on the contract chain of the side chain of the public chain, and the accounts corresponding to each application node are stored on the public chain, after receiving the lock-up information in the transaction request, the transaction contract will send a cross-border transaction to the public chain. Chain lock-up information, including which account and how much equity in the account is cross-chain lock-up. When the public link receives the relevant cross-chain lock-up information, it locks up according to the relevant content in the cross-chain lock-up information.

Step S43, judging whether the transaction objection information is received;

If the buyer and the seller have any objection to the transaction process, or send the dissenting information to the exchange, it will be judged that there is an objection in the transaction process and the exchange needs to arbitrate. .

Step S44, when the transaction objection information is not received and the transaction confirmation information is received, the cross-chain transfer information is sent to the public chain according to the transaction confirmation information, so that the public chain transfers the locked rights and interests;

The exchange will ask the seller to confirm when the buyer transfers, and at the same time ask the buyer and seller whether there is any objection to the transaction process. If there is no objection, the exchange will send a transaction confirmation message to the transaction contract to tell the transaction contract that the buyer and seller have reached an agreement and the transaction will be completed. It can be carried out normally, and transfers can be made. After the transaction contract receives the transaction confirmation information, it sends the cross-chain transfer information to the public chain according to the transaction confirmation information, so that the public chain completes the transfer, thus ending the entire transaction process and completing the corresponding transactions between buyers and sellers.

In this embodiment, the transaction contract in the smart contract supervises the transaction process of the buyer and the seller, and can accept the information sent by the exchange and want to transmit the information to ensure the security in the transaction process.

Further, referring to FIG. 4 and FIG. 5 , based on the above-mentioned embodiments of the smart contract management method of the present application, a fourth embodiment of the smart contract management method is provided. In the fourth embodiment,

After step S43, it includes:

Step S45, when receiving the transaction objection information and the arbitration confirmation information, obtain the multi-signature information in the arbitration confirmation information;

During the transaction between the buyer and the seller, if the buyer and the seller have objections to the transaction process, such as the amount of the transaction, the transaction method or other agreed information in the transaction process, the exchange will arbitrate the corresponding transaction, that is, to judge the transaction. What should the actual transaction information look like in the transaction process? Because the information in the blockchain is traceable, the exchange can judge the real transaction information by querying the information related to the transaction recorded in the entire blockchain. After the exchange makes the arbitration, it will send the arbitration confirmation information and multi-signature to the transaction contract. Multi-signature includes the platform signature and the signature of the winning party in the arbitration result.

Step S46, verifying the multi-signature information;

After receiving the arbitration confirmation information and the multi-signature, the transaction contract verifies the received multi-signature to judge the authenticity of the arbitration confirmation information and obtain the winning party in the arbitration to ensure the authenticity of the relevant information.

Step S47, if the verification is passed, send cross-chain transfer information to the public chain according to the arbitration confirmation information;

After the information verification is passed, the transfer information is sent to the public chain according to the arbitration confirmation information, so that the public chain can complete the transfer operation. If the arbitration result is that the buyer wins, the arbitration confirmation information includes the buyer's winning information, and the multi-signature includes the platform signature and the buyer's signature. At the same time, the public chain will transfer money according to the cross-chain transfer information. If the seller wins, the arbitration confirmation information It contains the seller's winning information, and the multi-signature includes the platform signature and the seller's signature.

Wherein, the transaction request and the arbitration confirmation information are generated by a decentralized exchange. Generally, the decentralized exchange can be a dedicated W-CBEx exchange or other decentralized exchanges that meet the contract requirements.

In this embodiment, when there is disagreement between the buyer and the seller in the transaction process, the exchange will arbitrate the transaction process, the transaction contract will determine the final cross-chain transfer result according to the arbitration result, and the fairness in the transaction process will be ensured through the arbitration mechanism.
