## Claims and open questions

- Hoskinson wrote on X that he is personally developing a programming language for Cardano with Lucas Rosa, a software engineer at Input Output Global who co-created Aiken, according to CoinDesk.
- Hoskinson said the language would support three tools: transaction intents, proof-carrying data and Groth16 proofs, CoinDesk reported.
- Hoskinson has not shared the language's name, any public code or a date when developers can start using it, CoinDesk reported.
- What the language will be called and when developers will be able to use it, which would be confirmed by a project announcement or published code and documentation.
- Whether the language will replace or complement existing Cardano smart contract languages such as Plutus and Aiken, which would be clarified by an official statement from Input Output Global.
