Embodiment Construction

[0049] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be noted that the following embodiments are intended to facilitate the understanding of the present invention, but do not limit it in any way.

[0050] Such as figure 1 As shown, the smart contract monitoring system for blockchain supervision includes: business rule management module, contract template management module and business contract operation state management module.

[0051] The workflow of the smart contract monitoring system is as follows: figure 2 As shown, the details are as follows: by defining contract business rules to describe metadata information, you can customize and upload business rules for registration, and at the same time automatically generate business contract templates for specific business types; by extending the standard library supervision functions of the smart contract virtual machine, The wasm (WebAss...

Abstract

The invention discloses an intelligent contract monitoring method and system for blockchain supervision, and the method comprises the steps: defining contract business description metadata information, and registering a business rule on a supervision contract; generating an intelligent contract template for the specific business; the intelligent contract template injects a code logic for registering basic information of a current business contract to the supervision contract in an initialization method of the business contract, and adds a code logic for reporting specific data to the supervision contract in a business process method associated with the supervision message; when the business contract is deployed on the blockchain platform, registering the business contract to a supervisioncontract; the supervision contract analyzes the business contract and verifies whether the business contract satisfies an associated contract business rule; and when the business contract is called and the contract method associated with the supervision event is called, actively delivering a corresponding supervision message to the supervision contract. According to the invention, a penetrating contract management and control capability is provided, so that the service compliance on the blockchain is ensured.

Description

technical field [0001] The invention relates to the fields of block chain and supervisory technology, in particular to a smart contract monitoring method and system for block chain supervision. Background technique [0002] With the continuous and vigorous development of blockchain technology represented by Bitcoin, blockchain technology has gradually surpassed the era of programmable currency and entered a new era of large-scale application based on smart contracts. [0003] In the process of traditional informatization construction, the system data of various institutions lacks a safe and effective way to share. For the regulatory authorities, it is difficult for the regulatory system to safely connect with the regulated system, and it is impossible to realize real-time regulatory audit. Blockchain technology responds to real pain points, integrates distributed, consensus, encryption and other technologies, and establishes a secure intercommunication and sharing mechanism...
