Ownership Attestation
A verifier asks a question, the owner of a bond signs the answer, and the verifier checks the signature against the contract. It proves who owns a bond at one block. It is not a zero-knowledge proof: the signing address and the bond are both visible.

Ask an owner to prove a bond is theirs
You make a challenge and send it to the person who claims the bond. It names the bond, this network and contract, who is asking, a random nonce and an expiry. It holds no secret; any channel will do.
