STARK Lab: An Interactive Deep Dive into Zero-Knowledge Proofs
STARK Lab is an interactive, visual environment for exploring how STARK proofs work.
In the world of zero-knowledge proofs, protocols like STARKs are often treated as “moon math”. Even experienced security researchers tend to treat STARKs as oracles rather than inspecting their internal logic because the underlying mathematics feels too intimidating.
I’ve always found that the fastest way to truly understand a system is to debug it. Being able to inspect intermediate states, break invariants, and see why something fails has helped me internalize complex systems far more effectively than reading equations in isolation. That’s why I built STARK Lab, an interactive, visual environment for exploring how STARK proofs actually work end to end.
The app lets you:
- Write small programs using a simple assembly-style DSL
- Generate and verify STARK proofs for those programs
- Inspect execution traces, constraints, and polynomials
- See how changing a program or constraint affects the proof
- Learn the core ideas behind STARKs through hands-on exploration
The site also includes explanations of the underlying math and links to further reading if you want to go deeper.
Who Is This For?
STARK Lab should be useful for security researchers who want to audit or reason about ZK systems, as well as protocol engineers building or integrating STARK-based designs. Note that this is not a production prover.
It’s a learning, debugging, and inspection tool — designed to make STARKs feel understandable rather than mystical.
Explore It Yourself
If you’ve ever wanted to look inside a STARK proof and see what’s really going on, I hope this tool helps.
