RiB Newsletter #39

September 07, 2022

Welcome to the #39 edition of Rust in Blockchain, the monthly newsletter about Rust, distributed systems, cryptography, and other industry topics. Previous: #38.

Thanks

Thanks to contributors: Dan Shields, djddo, Eli Corrales, Ganzaro, Hunter Trujillo, Mayoeba Yabureru, Paul, Piotr Dziubecki, Rodairos, Brian Anderson, and Aimee Zhu. Thank you for your help!

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 by submitting a PR to the next draft.

Project Spotlight

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

automerge-rs.

Automerge is a popular JavaScript library for working with conflict-free replicated datatypes (CRDTs). CRDTs allow multiple parties to independently make changes to a shared data structure, while guaranteeing that those changes can all be resolved unambiguously in the future. The most commonly-understood use of CRDTs is in collaborative document editing. Automerge is network-protocol agnostic and can be used in asynchronous contexts.

automerge-rs is a re-implementation, by the original authors, in Rust, and is wasm-compatible.

Rust in Bitcoin

Lots of activity in BDK and LDK this week. Be sure to scroll down to their respective sections for links to details on the new developments. LNP/BP also did a number of talks recently, but no recordings have been published yet. Also, rust-bitcoin 0.29 was released, with BIP-152 support, and it’s now using Rust 2018 and enables clippy support in CI, which will make it easier to make contributions in the future.

For discussion join the Rust in Bitcoin Telegram group.
