zkGolf is a competition to build the cheapest zero-knowledge circuits, proven correct in Lean 4. Pick a challenge, write a leaner circuit, and prove it stays correct against the spec. Verified submissions are scored on cost (allocations plus constraints); the tighter your circuit, the further under par you land.
