Problems solved by technology

[0007] However, the problem with the above two types of technologies is that they only model the behavior of each transaction in the contract, and lack of modeling the relationship between transactions, resulting in the loss of transaction relationship information, so that some relationships with transactions cannot be analyzed in the subsequent verification process. Related vulnerabilities, such as transaction order dependency vulnerabilities, etc.

Abstract

The invention discloses an Ethereum intelligent contract-oriented protocol automatic formalized modeling method and system, which can model behaviors of transactions in a contract and also can model relationships (namely sequences and block variables of transactions) between the transactions on the premise of not needing manual participation, so that the method and the system have the advantages that the modeling efficiency is greatly improved, and the system and the method are suitable for popularization and application. The method can be applied to verification: 1) whether a specific security attribute is satisfied under different transaction sequences; 2) whether transactions in different blocks meet specific attributes or not can be used for analyzing bugs such as overflow and reentry, and can also be used for automatically analyzing bugs of transaction sequence dependence and block variable dependence.

Description

technical field [0001] The invention relates to the technical field of Ethereum smart contract security analysis and formal verification, in particular to a protocol automatic formal modeling method and system for the Ethereum smart contract. Background technique [0002] Ethereum is currently one of the most mainstream blockchain platforms. An Ethereum smart contract is a piece of program code that exists on the Ethereum chain and can be triggered to execute. Smart contracts have the characteristics of traceability and non-tampering, so they can be used as transaction agreements between different accounts on the Ethereum platform. [0003] It is difficult to change the Ethereum smart contract after it is deployed, so once there is a code loophole, it may cause security problems for the relevant account (contract deployer or contract user). In order to ensure its security, formal verification methods can be used to analyze and verify the security of the contract before dep...
