Hoskinson Says He Is Building a New Programming Language for Cardano

The project seeks to let applications attach compact cryptographic proofs to user requests so the chain can verify outcomes without redoing heavy computation.

Overview

  • Charles Hoskinson announced on X that he is personally developing the language and named Input Output Global engineer Lucas Rosa as his collaborator.
  • He described three technical goals for the tool: transaction intents to express user requests, proof-carrying data to attach verifiable evidence, and Groth16 zk‑SNARK proofs to keep those proofs small and quick to check.
  • No name, public specification, source code, or timeline for developer access has been released, leaving the effort at an early, non-public stage.
  • The announcement positions the new language alongside existing Cardano tooling such as Plutus and Aiken and IOG’s Compact language used on the Midnight privacy chain.
  • Founder-led engineering could steer Cardano toward more off‑chain computation with on‑chain verification, but practical impacts on developer tools and app design remain uncertain until IOG or Hoskinson publish details.
