A simulator of Solidity-style smart contracts in the theorem prover Agda
Fahad Alhabardi, Anton Setzer · 2023
This paper extends the previous paper [6] by implementing two blockchain simulators of Solidity-style smart contracts – a simple and a complex one, using the interactive theorem prover Agda. In the previous article [6], we built a simple and complex abstract model of Solidity-style smart contracts in Agda. These models had many features, such as calling different smart contracts, supporting the ability to call different smart contracts, and providing simple and complex instructions. Because of the use of coalgebras for representing smart contracts they supported loops and conditionals, using the support of those features for coalgebraic programs in Agda. The complex model supported gas costs and pure functions, similar to the Solidity language.
