Cardano SL is the original Haskell implementation of the Cardano cryptocurrency, implementing the Ouroboros proof-of-stake consensus protocol. The codebase is deprecated and superseded by the modular Shelley-era components such as cardano-node and cardano-wallet.

Use cases

  • run a Cardano proof-of-stake blockchain node
  • study the Ouroboros consensus protocol implementation
  • explore legacy Cardano SL source code
  • research proof-of-stake cryptocurrency design in Haskell

When to choose

  • you need to read or audit the original Ouroboros PoS implementation
  • you are researching the history of Cardano's codebase

When to avoid

  • you want to run or build on Cardano today - use cardano-node and related components instead
  • you need an actively maintained blockchain node
  • you want Shelley-era features or current wallet support
