According to @ItsDave_ADA, Cardano needs broader support for multiple widely used programming languages in transaction building and blockchain synchronization, stating current tooling is not acceptable or competitive for increased transaction growth; source: twitter.com/ItsDave_ADA/status/1975691508184719373. Cardano smart contracts are primarily based on Plutus, a Haskell-driven framework, with Marlowe and Aiken available as additional languages for the ecosystem; sources: docs.cardano.org, docs.cardano.org/marlowe, aiken-lang.org. Multi-language SDK efforts already exist via TypeScript libraries like Lucid, Rust and TypeScript cardano-serialization-lib, Java cardano-client-lib, and Python PyCardano, highlighting ongoing attempts to widen developer access; sources: github.com/spacebudz/lucid, github.com/Emurgo/cardano-serialization-lib, github.com/bloxbean/cardano-client-lib, pycardano.readthedocs.io.
