Cardano’s Trickery: Bitcoin’s Smart Contracts Without a Single Change!
The thread describes a relay of representations that begins with high-level source code and ends inside Bitcoin Script. First, Cardano’s tool-chain lowers the contract into Untyped Plutus Core (UPLC), a stripped-down functional bytecode. UPLC is then serialized and handed to a miniature interpreter known as the Control–Environment–Continuation (CEK) machine. Instead of asking Bitcoin to interpret UPLC directly, IO compiles the CEK machine itself into RISC-V, “a real-world, simple CPU instruction set.” The resulting RISC-V program becomes the payload that Bitcoin ultimately verifies, with the serialized UPLC passed to it at run-time. 🧠⚡
