Welcome to the #41 edition of Rust in Blockchain, the monthly newsletter about Rust, distributed systems, cryptography, and other industry topics. Previous: #40.
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.
Each month we like to shine a light on a notable Rust blockchain project. This month that project is…
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.
- Blockchain Consensus Mechanisms Compared. Just an easy to understand basic overview.
- Creating wasm-opt Rust bindings with cxx
- Introducing Noir: The Universal Language of Zero-Knowledge. We have spotlighted this project previously.
- Polygon zkEVM Architecture
- MEV Resistance on a DAG. A good explanation of the new generation of high-throughput DAG-based consensus protocols like Narwhal / Tusk. This one introduces Fino.
- Secure Randomness: From Zero to Verifiable Delay Functions, Part 1
- Public Randomness and Randomness Beacons
- Explained: The BNB Chain Hack (October 2022)
- Security Analysis of Avalanche Consensus
- Beyond IBC
- Major New Cryptowatch Desktop Trading Release using fast Rust-native GUI Framework
- Hyperproofs: Aggregating and Maintaining Proofs in Vector Commitments
- Flexible Anonymous Transactions (FLAX): Towards Privacy-Preserving and Composable Decentralized Finance

- Secure Distributed Key Generation for Discrete-Log Based Cryptosystems
- BG: A Modular Treatment of BFT Consensus
- FairPoS: Input Fairness in Proof-of-Stake with Adaptive Security
- Eagle: Efficient Privacy Preserving Smart Contracts
- An efficient verifiable state for zk-EVM and beyond from the Anemoi hash function
- Report: Validity Rollups on Bitcoin
- 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
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
For discussion join the Rust in Bitcoin Telegram group.
Fedimint is a Bitcoin banking protocol. Highlights from the last month include:
- Distributed key generation so federation setup has no single point of failure
- Modularization so that developers don’t have to fork the repo to modify functionality
- Proper database transactions
- Improved connection to Lighting Network
- Deriving our anonymous IOUs from a cryptographic seed to enable safer recovery schemes
