An early architectural concept from Cardano's original roadmap that imagined two layers: a "settlement layer" for value transfer and a "computation layer" for running smart contracts. In practice, smart contract execution was built directly into transaction validation in the eUTXO model rather than existing as a separate layer. The term still appears in older Cardano writing and is kept here for context.
