One test proof, checked in front of you

This is a TEST proof in the scoped-proof format Almstins is building for Verify. It is signed with a throwaway TEST key, not Almstins' production key, and its digest is anchored in a Bitcoin block through OpenTimestamps. Nothing below trusts our word. Your browser recomputes every check live with real cryptography, and you can check the timestamp yourself against the public chain.

What this proof claims

Scope is explicit. This proves control of the address only. It is not a claim of legal ownership of any underlying asset, and not a statement that the address is safe to transact with.

What "Verified" means here — and what it never claims

Unaltered and dated

An unaltered proof in the Almstins format, signed with a TEST key and submitted for a Bitcoin timestamp. This part is fully checked below. It vouches for the document, and, once Bitcoin confirms the receipt, for when it existed.
Control of the address — not who holds it

It attests that whoever controls this address proved it with an action only the key-holder can take. When the claim is an on-chain action, the record can carry a transaction hash so you pull it off the chain yourself — the hash and the status are optional, since not every claim is on-chain. In this demo the self-send entries are illustrative.
Never a person

Almstins does not link an address to a legal identity. It proves control, never ownership by a named party. That refusal is the design, not a gap.

What your browser just checked

Bitcoin timestamp

—

Block time of the Bitcoin transaction that commits this proof's digest. Almstins cannot forge or backdate it — it would have to rewrite Bitcoin.

Anchor: OpenTimestamps → Bitcoin
Digest

Confirm it independently. Download the raw OpenTimestamps receipt and verify it against Bitcoin yourself — with the OpenTimestamps client or web verifier. It resolves to the same block time without asking Almstins anything.

Honest framing: the cryptography here is entirely real: the Ed25519 signature, the Merkle root, and the OpenTimestamps submission to Bitcoin. But this is a TEST proof. It is signed with a throwaway TEST key, not Almstins' production signing key (the only key published at /.well-known/almstins-signing-key.json), and isTest: true sits inside the signed manifest, so the mark cannot be removed without breaking the signature. The record set inside the proof is illustrative — sample self-send entries, not a live wallet. What a production proof adds is the wiring that fills this exact structure with independently verified facts. The proof container is done; connecting the facts is the build.

This test proof shows the proof format Almstins is building for Verify. Claim and prove control of your own address — no wallet connection, no private keys.

Try Almstins Verify almstins.com

Verified locally with your browser's WebCrypto — SHA-256 Merkle tree, RFC-8785 canonical manifest, and Ed25519 signature. No request leaves this page to check the proof. The TEST key that signed this proof was generated in memory for this one signing, never saved, and discarded afterward. Its key ID is not Almstins' published production key (listed at /.well-known/almstins-signing-key.json), so this proof cannot pass as a real Almstins record.
