The DeFi Download

MLABS - Building dApps on Cardano, Polkadot, Solana, and Radix

• Radix DLT

Share episode

In this episode of the DeFi Download, Piers Ridyard is joined by Ben Hart, CTO, and Amir, blossoming Scrypto developer at MLabs. Ben and Amir share their experience with different programming languages and platforms, such as Haskell, Plutus, Rust, and Scrypto. 

Summary

MLabs is a Haskell, Rust, and Blockchain AI consultancy working with various industries, such as fintech and blockchain. MLabs is also the developer of the Plutonomicon library, a major contributor to it, and one of the main contributors to the Plutarch eDSL version of the Plutus smart contract language.

Key takeaways

  • Ben came across Radix at Consensus 2023 and was impressed with the thoughtfulness and organization of the Radix team and builders. He found it easy to jump into Scrypto because of his previous experience with Rust. 
  • Amir found Scrypto to be easier to learn and use than Plutus because it abstracts away some of the lower-level details and has well-named concepts and design patterns. Amir was able to quickly understand and experiment with Scrypto by reading the documentation and the community examples that are available.
  • Radix’s guardrails and intent-based transactions make programming and building applications easier and safer, unlike Ethereum’s state-based transactions. It is difficult to explain Radix’s advantages to someone who has not faced Ethereum’s challenges.
