Problems solved by technology

This includes testing and static analysis, but testing and static analysis cannot cover all potential defects
[0006] The current smart contracts are very short, and it is relatively not difficult to formally verify them. Due to their characteristics, the cost of all defects in smart contracts is very expensive, so it is worthwhile to conduct formal verification of smart contracts as comprehensively as possible.

Abstract

The invention discloses a smart contract development and verification method based on Noeses logic, and the method comprises the steps: preparing an interactive theorem prover and an abstract machinefor a smart contract on the interactive theorem prover, wherein the abstract machine for the smart contract comprises the smart contract and the abstract machine; on the interactive theorem prover andthe abstract machine for the smart contract, realzing a scheme of separation of calculation and states, and transferring all states and recording the same in an instruction mode; calculating an smartcontract through a transfer instruction based on the scheme of separation of calculation and states; and after the smart contract is calculated, writing the smart contract into a blockchain. The smart contract development and verification method based on Noeses logic has the advantage that the development and verification process of the zero-defect code of the smart contract on the blockchain canbe realized. According to the formalized verification method, the formalized analysis efficiency of the smart contract is improved, so that the execution efficiency of the smart contract is improved,and the security of the smart contract in the execution process is ensured.

Description

technical field [0001] The invention belongs to the fields of formal verification technology, smart contract technology and block chain technology, and specifically relates to a Noesis logic-based smart contract development and verification method. Background technique [0002] With the development of computer information technology, the value of blockchain technology has been gradually recognized and widely used, and it has provided a development platform for smart contract technology that has never been able to find a basis for development. As one of the basic technologies of blockchain technology, smart contract technology can be developed and put into application relying on blockchain technology. Blockchain technology is a distributed database technology that verifies and stores data with a block chain data structure. At the application level, more people are willing to understand it as a consensus algorithm that uses distributed nodes to ensure data consistency. Techno...
