About Me
Hi, I am Rasmus Kirk. I hold a bachelor’s degree in Computer Science from Aarhus University, Denmark, and I am currently pursuing a master’s degree with a specialization in Cryptography (specifically SNARKs) and Formal Software Verification, that I will finish March 2026. I have been working part-time as a student worker at Concordium, a cryptocurrency firm, for about three years, primarily writing in Rust.
Here is a list of some of my software interests:
- Decentralized Technologies
- Cryptography
- SNARKs
- Zero-Knowledge Proofs
- Free and Open Software
- Functional Programming
- NixOS
- Linux
Some notable projects:
- Roping in Lasso: An accessible guide to Lasso, which enables lookup arguments from much larger tables than previously possible. Lasso is the primary component of Jolt, the SNARK‑based virtual machine (zkVM) that proves correct execution for RISC-V programs via large table lookups
- My Master’s thesis: Where I implemented the Halo2 proof system and used it to prove correct blockchain light node catch-up.
- My bachelor’s thesis: High Assurance Cryptography - Implementing Bulletproofs in Hacspec
- A Rust Toy-Blockchain: A toy blockchain project based on the exercises from the course “Distributed Systems and Security” from Aarhus University.
- Halo2 Accumulation in Rust: A Rust implementation of the accumulation scheme used in halo2. The repo also contains a report explaining the background, theory and implementation details of the project.
- Nixarr: A Nixos module that aims to make the installation and management of a home media server as easy, and pain free, as possible.
- Submerger: Combines subtitles from two files into one, with customizable position and color settings.
- Rustle: An open source rust program that keeps your speakers active.
Feel free to explore my projects and reach out if you have any questions.
Experience
Student Software Engineer | Concordium October 2022 – March 2026 (approx. 3.5 years)
Smart contract tooling: Mainly around testing and building infrastructure related to the WebAssembly smart contracts.
SDK Development - Maintaining and expanding the capabilities of the SDK’s (Rust, JS, Dotnet).
Rust Services Fixing and expanding various Rust-based services.
I’ve also participated in discussions with the Science Team related practical applications to the SNARK-based studies I’ve been pursuing in my Masters.
