zkGolf

Code golf communities usually optimize for character count, so applying the same competitive-minimization instinct to zero-knowledge circuits with formal verification in Lean is a fun crossover of two fairly nerdy subcultures. It turns an obscure and often intimidating field into a leaderboard game, which is a clever way to get more people poking at ZK internals. This feels like the kind of project that quietly teaches you real cryptography while you are just trying to shave off constraints.
