RiB Newsletter #41

Welcome to the #41 edition of Rust in Blockchain, the monthly newsletter about Rust, distributed systems, cryptography, and other industry topics. Previous: #40.

 

Thanks

Thanks to contributors: djddo, Hunter Trujillo, maxim, 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…

tlock-rs and zk-timelock.

These projects, both by the same author, implement timelock encryption, by which data can be encrypted and then only decrypted after a certain moment. It relies on the drand randomness beacon.

Papers

Projects

  • Cartesi Rollups. It contains the on-chain and off-chain pieces that are used to deploy, launch and interact with Cartesi Rollups DApps.
  • zkcreds-rs. A cryptographic library for designing anonymous credential systems in a flexible, issuer-agnostic, and efficient manner using general-purpose zero-knowledge proofs.
  • zk-timelock. Arkworks circuits for verifiable time-lock encryption.
  • rs-tlock. Pure Rust implementation of drand/tlock scheme. It provides time-based encryption and decryption capabilities by relying on a drand threshold network and identity-based encryption (IBE).
  • fastcrypto. MystenLabs’ crypto library.

Rust in Bitcoin

It’s been a crazy month in the Bitcoin space. In light of the mayhem happening on LND, it bears mentioning there are two Rust Lightning implementations, LNP and LDK, activity on both listed below. In lighter news, Iris wallet, an Android Bitcoin wallet that supports RGB tokens was released, and it makes use of rgb-lib, behind Kotlin language bindings using rust-ffi. LDK released 0.0.112, a largely incremental release to meet expanding use-cases as the project matures. BDK 0.23 was released shortly after last newsletter, and they’re now gearing up for a 0.24 release containing support for rust-bitcoin 0.29, as mentioned in RiB #39. The Fedimint team is working hard on new features, including an experimental web interface, and a 2nd-generation key generation system based on discrete-log cryptography, which should be more secure. Finally, bitmask-core 0.4 was published, with support for Taproot P2TR addresses, and also LNDHub support.
