RiB Newsletter #15 – Turbofish in the Blocksea

Welcome to the #15 edition of Rust in Blockchain, the hypest newsletter about the hypest tech. Previous: #14.

Rust blockchain development continued at its typical blistering pace, and again it’s impossible to follow everything going on.

This month we see continued advancement in zero-knowledge computing, an obvious focus from the entire blockchain industry on the DeFi phenomenon, and some new hackathons with opportunities for Rust developers.

Every month seems to bring advancements in zero-knowledge proofs, and new implementations in Rust. It is a research area that will probably impact the general computing industry eventually, and one where the blockchain industry is leading the way, and one where Rust has a huge foothold. Even projects that are not written in Rust we see implementing their zero-knowledge cryptography in Rust. But this stuff is extremely technical, and improving at a rapid pace. We fear we will never understand it.

There are several Rust blockchains now in development that are built around zero-knowledge VMs, whose smart contracts create zero-knowledge proofs:

  • Aleo. A new platform with its own zero-knowledge programming language, Leo.
  • Slingshot. A research project from Stellar.
  • Dusk. Not entirely in Rust.

These are networks that support nearly arbitrary computation over secret inputs. Like programable Zcash.

Speaking of Zcash, the zkSNARK pioneers announced their next-generation zero-knowledge proof system, called Halo 2, which uses a new zkSNARK construction, PLONK.

Two projects built on Rust blockchains launched this month: Serum, a decentralized exchange built on Solana; and Flux, a prediction market built on NEAR. Soon Secret Network launches their mainnet.

Finally, Mozilla laid off all but one of its full-time Rust employees. There are a few other people left at Mozilla who actively contribute to Rust as part of their role in Firefox, but this mostly ends Mozilla’s commitment to Rust’s development.

There’s no need to worry though. Rust was designed to outlive Mozilla’s withdrawal, and the project will continue nearly unaffected.

Project Spotlight

Each month we like to shine a light on a notable Rust blockchain project. This month that project is…


This is a blockchain with built-in software license management. We’re excited about this because license management is a rare non-currency use case for blockchains that makes a lot of sense. While we might expect to see more blockchain platforms devoted solely to digital licensing, fluence is actually a complete distributed computing platform, with a unique vision about using license management to generate profit from open source software.
