Embodiment Construction

[0068] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0069] Aiming at the security issues that are concerned by users in the current block chain system; the present invention applies the formal method to the block chain system security verification, and is used for the security verification of computer software and hardware. The invention uses MSVL to model the block chain, uses PPTL to describe the property of the block chain, and finally verifies in the MC to determine whether the property of the block chain is correct.

[0070] The application principle of the present invention will be described in detail below in conjunction with the accompanying drawings.

Abstract

The invention belongs to the field of formalization methods, and discloses a blockchain system modeling and safety verification method and system based on an MSVL. The method comprises the following steps: modeling a blockchain system by using the MSVL in MC, and representing the blockchain system by a program p; describing the property of the blockchain system by using a PPTL, and expressing theproperty by a formula phi; and in the MC, adding a modeling program p of the MSVL and the property phi described by using the PPTL, and verifying the safety of the blockchain system. According to theblockchain system modeling and safety verification method based on the MSVL provided by the invention, the blockchain is modeled by using an MSVL program, and the safety property of the blockchain isdescribed by using the PPTL; the PPTL is a proposition subset of PTL, and the MSVL is an executable subset of the PTL, so that the MSVL and the PPTL can be executed in the MC in a unified mode; compared with other methods, the method does not need to use another formal languages and also does not need to call other tools and a lot of manual certifications, and only needs to provide a PPTL formulaof the property to be verified, so that the proof process is automatically completed by the MC.

Description

technical field [0001] The invention belongs to the technical field of computer-aided design, and in particular relates to a method and system for modeling and safety verification of a block chain system based on MSVL. Background technique [0002] At present, the existing technologies commonly used in the industry are as follows: At present, the technological development of system applications using blockchain technology can be roughly divided into three stages. The first stage mainly develops into a digital encrypted currency system; the second stage mainly develops into a financial system; the third stage mainly develops into a blockchain society. We are currently in the early stages of Phase 2, and we certainly won't be in that period for long. The blockchain organizes data with time clues, and packs the data into blocks every once in a while, and then links these blocks in a chain and chronological order to form a specific data structure, which ensures its traceability...
