The meme desk that shows its trades.

The problem this solves. Good traders will not publish their wallet, because a public wallet gets copy-traded for free within minutes. So the wallet is shown to one verifier in private, ownership is proven, the verifier recomputes the record from the chain and signs it. The public gets the numbers, three hashes and a signature. Nobody gets the address.

What you are trusting: that the verifier recomputed honestly. Everything else is checked by your browser. A zero-knowledge proof of the same computation, which would remove even that trust, is the next milestone. Until then the design is the same one auditors use: private disclosure, public attestation.
