ライブラリー > Functional Blockchain Contracts
This paper describes Plutus Platform, a functional blockchain smart contract system for coding distributed applications on top of the Cardano blockchain. Most blockchain programming platforms depend on a custom language, such as Ethereum’s Solidity, but Plutus is provided as a set of libraries for Haskell. Both off-chain and on-chain code are written in Haskell: off-chain code using the Plutus library, and on-chain code in a subset of Haskell using Template Haskell. On-chain code is compiled to a tiny functional language called Plutus Core, which is System Fω with iso-recursive types and suitable primitives.
Plutus and Cardano are available open source, and Plutus Playground provides a web-based IDE that enables users to try out the system and to develop simple applications.
