#239 Grigore Rosu: The K framework – a framework to formally define all programming languages
In the past few years, we witnessed the development of multiple smart contract languages – Solidity, Viper, Michelson, Scilla etc. These languages need to enable developers to write correct, predictable behavior smart contract code. Each language development effort therefore ends up spending resources into building formal verification toolsets, compilers, debuggers and other developer tools.
We also cover his efforts to express the Ethereum virtual machine using the K framework, and to develop a new virtual machine technology, called IELE, specifically tailored to the blockchain space. Check out the episode to understand a game changing technology in the formal verification and smart contract safety space.
Topics discussed in this episode:
- Grigore’s background with NASA and work on formally verified correct software
- Motivations to develop K framework
- Basic principles behind the operation of K framework
- How K deals with undefined behavior / ambiguities in a language definition
- The intersection of K framework and smart contract technology
- Runtime Verification’s collaboration with Cardano
- KEVM and IELE, smart contract virtual machines developed by Runtime Verification
- Broader implications of the K framework for the blockchain industry
