Building on Bulletproofs
Published:
Link to Medium post. I explain how Bulletproofs works, and how we’re building a confidential assets protocol and confidential smart contract language using this proof system. This post was originally written for the MIT Digital Currency Review newsletter.

Programmable Constraint Systems for Bulletproofs
Published:
Link to Medium post. I discuss the programmable constraint system (R1CS) API for writing custom zero knowledge proof circuits over Bulletproofs. I also introduce Cloak, Chain’s Confidential Asset framework that uses custom proofs built using this API.
Multi-Party Computation in Rust with Session Types
Published:
Link to Medium post. I discuss how to use Rust’s memory model to implement session types, which is useful for enforcing correct state transitions in multi-party computation protocols.
