Been thinking about how @union_build uses ZK reputation proofs… it’s actually pretty smart.

Instead of just logging your testnet activity the usual way, they use zero‑knowledge to prove what you’ve done, across different chains, without exposing all your data.

✅ You get real credit for your contributions
✅ Your privacy stays protected
✅ And it all works no matter how many ecosystems you test on

So your wallet isn’t just a wallet anymore, it becomes this onchain resume of real participation.

In a multichain world, that changes a lot.
Not just collecting points, but proving your effort in a trustless way.

Union’s not just tracking users; it’s building actual onchain merit.
