RiB Newsletter #14 – Are We Smart (Contract) Yet?

Welcome to the #14 edition of Rust in Blockchain, the hypest newsletter about the hypest tech. Previous: #13.

We’re seeing a bunch of interesting Rust blockchain and crypto projects, so this month the “Interesting Things” section is loaded up with news, papers, and project links.

This month, Elrond, appeared on our radar with the launch of their mainnet. Although not written in Rust, it runs Rust smart contracts on its Arwen WASM VM, which itself is based on the Rust Wasmer VM. Along with NEAR, Nervos, and Enigma (and probably others), this continues an encouraging trend of blockchains enabling smart contracts in Rust. See the “Interesting Things” section for examples of Elrond’s Rust contracts.

Rust continues to be popular for research into zero-knowledge proofs, with Microsoft releasing Spartan, a zk-SNARK system without trusted setup.

In RiB news, we published a late one-year anniversary blog post. It has some reflection on the changes to, and growth of, RiB over the last year.

The Awesome Blockchain Rust project, which is maintained by Sun under the rust-in-blockchain GitHub org, has received a stream of updates recently, and is now published as the Awesome-RiB page on rustinblockchain.org.

It’s a pretty good resource for finding blockchain-related Rust projects, with links to many of the more prominent and mature projects noted in the RiB newsletter. It could use more eyes on it though.



This edition of RiB was produced with contributions from Calvin Lau, Darosior, EnforSys, Paulii Good, Sol, Tony Arcieri, Brian Anderson, and Aimee Zhu. Thank you for your help!

Also, Awesome Blockchain Rust has been updated. Thanks to the awesome contributors: Alfredo Garcia, Andy Nogueira, ChainSafe Systems, Lane Rettig, Michael Sproul!

RiB needs help to keep up with Rust blockchain projects. If you follow a particular project, or otherwise find information that is beneficial to the Rust & blockchain community, please contribute to the next issue. Either submit a PR to the #15 draft, or Tweet @rust_blockchain.


Project Spotlight

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


ethers.rs is an Ethereum & Celo library and wallet implementation, implemented as a port of the ethers.js library to Rust.

Ethereum client programming is usually done in JavaScript with either web3.js or ethers.js, with ethers.js being the newer of the two. These clients communicate to an Ethereum node, typically via JSON-RPC (or, when in the browser, via an “injected” client provider that follows EIP-1193, like MetaMask).

ethers.rs then provides a strongly-typed alternative for writing software that interacts with the Ethereum network.

As of now it is only suited for non-browser use cases, but if you prefer hacking in Rust to JavaScript, as some of us surely do, it is worth looking into for your next Ethereum project.

The author of ethers.rs, Georgios Konstantopoulos, accepts donations to sponsor their work.

Note that there is also a Rust alternative to web3.js, rust-web3.
