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 The codebase is deprecated and superseded by the modular Shelley-era components such as cardano-node and cardano-wallet.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
