Description

Intelligent Service Trading System

technical field

The invention relates to the technical field of block chain applications, in particular to an intelligent service transaction system.

Background technique

The blockchain was born from Satoshi Nakamoto's Bitcoin. Since 2009, various Bitcoin-like digital currencies based on public blockchains have emerged. Blockchain is essentially a decentralized database, which has the advantages of decentralization, information tamper-proof, openness and transparency, and high robustness. A smart contract is a concept proposed by Nick Szabo in the 1990s. It is a computer program running on a replicable and shared ledger that can process information, receive, store and send value. In the blockchain context, a smart contract is a computer program running on a blockchain database that can execute itself when the conditions written in its source code are met. Since the smart contract is automatically executed and does not rely on the characteristics of a trusted third party, it can be trusted by users. In addition, due to the immutable nature of blockchain data, smart contracts are also immutable.

With the development of blockchain technology and the further promotion of smart contract applications, more and more people will come into contact with smart contracts in real life. Platforms such as Ethereum provide support for the deployment and implementation of smart contracts. Smart contracts can have innovative applications in the fields of finance and the Internet of Things, and they can provide services that some traditional central institutions cannot or are unwilling to provide. Smart contracts can provide a variety of smart services. At present, there is no fixed mode for smart service transactions based on smart contracts, and there are various forms, which are not conducive to overall maintenance and security analysis, and may have multiple potential security loopholes, which may easily cause economic losses.

Among them, use functions such as user information registration and transaction information verification provided by the block chain infrastructure module 170 oriented to group intelligence services, and further information provided by the demand side (of course, the demand side can also choose whether to provide according to the actual situation. This is not specifically limited), financial institutions that provide loans can refer to the traditional review process to conduct further data review on the demand side, including review of the company's audit report, dishonest behavior and other materials and information. The final review results of this part will be supervised by the regulatory authorities.

After the data review is completed, the two parties enter the negotiation stage of transaction content and parameters. In this stage, the two parties conduct further detailed negotiations on the requirements released during the prior matching. These details include the existing content in the requirements and the parts that are not in the requirements, such as some terms that cannot be accurately described in the contract. In the case that the needs of both parties of the matching results cannot be fully and simultaneously met, the two parties can complete the negotiation of parameters at this stage, that is, re-modify the specific parameters already in the requirements stated at the time of release, such as interest rates, years, etc. Similarly, the negotiation results of the transaction content will also be supervised by the regulatory authorities.

The module 150 mainly includes a smart contract construction platform, as well as contract security inspection facilities and a contract delivery acceptance platform. The contract construction platform provides a number of transaction options and input interfaces. Both parties to the transaction input the pre-agreed agreement parameters (such as loan conditions, loan amount, etc.) into the contract construction platform, and the platform will automatically generate a smart contract that includes the needs of both parties. Afterwards, the contract security inspection facility in the module 150 will provide a security check of the corresponding contract to ensure the logical security of the contract. When the smart contract generated by the construction platform passes the security inspection, both parties to the transaction can visually verify the contract on the smart contract delivery acceptance platform in this module, that is, display the contract in a certain visual way to verify the generated smart contract. Achievable functions. After final acceptance and confirmation by both parties to the transaction, the contract will enter the smart contract deployment and evolution module 150, which is deployed on the blockchain.

Further, in one embodiment of the present invention, the smart contract deployment and evolution module 160 is also used to update and adjust the content of the smart contract, or terminate and revoke the smart contract in advance when the preset condition is met.

Among them, supervision can be divided into ex-ante supervision, interim supervision and post-event supervision according to the time of supervision intervention.

Further, in an embodiment of the present invention, as shown in FIG. 1 , the system 100 of the embodiment of the present invention further includes: a subject credit dynamic evaluation module 190 . Among them, the subject credit dynamic evaluation module 190 uses the information obtained by the supervision module and the basic information of the transaction subject recorded on the blockchain infrastructure, financial statements and audit reports, default records and deferred repayment records to conduct a comprehensive evaluation of the transaction subjects in the entire system. Credit dynamic evaluation, and the evaluation results are recorded in the blockchain to provide users with reliable transaction subject credit information.

Specifically, subject credit dynamic evaluation module 190: This module 190 mainly uses part of the information obtained by the supervision module and the basic information of participants recorded on the blockchain infrastructure, financial statements and audit reports, default records, and deferred repayment records As well as other evaluation related materials, etc., the credit dynamic evaluation of the participants of the entire system is carried out, and the evaluation results are recorded in the blockchain to provide users with reliable participant credit information.
