The Plutus Core team is building the core of Cardano’s smart contract functionality on the bedrock of functional programming languages. This interdisciplinary team carries out original R&D and turns the results into production systems. This team has designed and implemented four languages for Cardano smart contracts (Plinth, Plutus IR, Typed Plutus Core, and Untyped Plutus Core) and improved the compiler and runtime with more built-in functions and optimizations, expanding the expressiveness, capability and security of smart contracts on Cardano. The team has formalized the semantics of Typed and Untyped Plutus Core using Agda, developed novel compilation techniques for data types, and Implemented a compiler for compiling Plinth into Untyped Plutus Core, which uses Plutus IR and Typed Plutus Core as intermediate representations. They also implemented evaluators for Typed and Untyped Plutus Core, in Haskell and Agda. They also contributed to Cardano ledger updates for smart contracts, and published peer-reviewed research. .
