Episode 169: Arkworks SNARK libraries with Pratyush Mishra

In this week’s episode, Anna and Robert Habermeier chat with Pratyush Mishra, co-author of the Arkworks toolkit. Arkworks is a collection of Rust libraries designed to simplify development with SNARKs, both for developing high-level application circuits and building custom SNARK implementations.

Pratyush lays out what possibilities and trade-offs Arkworks offers, diving into the details of the Rust implementation and why it is the best language for developing cryptographic primitives. Anna, Rob and Pratyush then branch out into the philosophical and practical questions of open-source and blockchain development.

Here are a few links to Arkworks and the topics they discussed:

Arkworks GitHub page and Telegram group.

Pratyush’s GitHub, Twitter and Berkeley pages.

Bellman and Libsnark, some of the other libraries that are similar to Arkworks.

The Celo and Mina protocols, two major projects using Arkworks.

Here is a basic explainer of what projects like Arkworks are trying to do and why it’s useful, with a particular focus on ZoKrates, one of the languages Pratyush mentioned.

Intros to Circom, Leo and Zinc, some of the higher level languages.

An earlier episode with Robert Habermeier about the work he does on Polkadot.
