Relational Verification of Smart Contracts
|Typ:||MA / PdF|
Ethereum is a platform for smart contracts: Programs which automatically manage resources in a decentralised network. Changing an Ethereum smart contract directly (e.g., to fix a bug or improve performance) is not possible: The contract has to be deleted, and a new contract can be deployed instead. But how to convince the stakeholders that the new version does the right thing? Does it really only fix a bug? Does it really behave identically except for improved performance? In a smart contract network, different agents do not necessarily trust each other - so we better had proof!
Formal verification for smart contracts is a very active research area. However, there is no established methodology for comparing the behavior of two different smart contracts.
Ethereum smart contracts are usually written in the Solidity programming language. In this project, the goal is to develop an approach for Relational Verification of smart contracts written in Solidity.
Understanding of first order and temporal logic as taught, e.g., in the Formale Systeme lecture.
