RiB Newsletter #33

Welcome to the #33 edition of Rust in Blockchain, the monthly newsletter about Rust, distributed systems, cryptography, and other industry topics. Previous: #32.

 

Thanks

Thanks to contributors: Dan Shields, David, John Adler, oiclid, 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…

teleport-transactions.

This is an implementation in Rust of CoinSwap, a long-discussed, but never implemented technique for improving the privacy and fungibility of Bitcoin. It involves an interactive agreement between two parties, performed over Tor, that results in exchanging ownership of two different addresses.
