CATALOGUE — V1

Seed proofs, precisely.

A timestamped ownership receipt today. A head start for the seed holder later.

FIG. 1 — ANATOMY OF A STAMP

A · CURVE KEY ONLY

Has scalar. No seed.

01Signs a valid signature · e.g. 7b21…

02Cannot reproduce exact signature

03Hash ≠ commitment · e.g. 1c04…

Can't prove an earlier stamp.

B · SEED HOLDER

Has the seed and deterministic prefix.

01Re-signs the same message

02Identical signature · e.g. 9f3a…

03Hash = on-chain commitment

Proves ownership first.

FIG. 2 — AFTER A BREAK · Earliest stamp wins. Only the seed can reproduce it.

A · YOUR BROWSER

64-byte signatureVerified and hashed here. It stays here.

B · SEEDPROOF + SOLANA

32-byte hash onlyPublished in a timestamped memo.

FIG. 3 — WHAT THE SERVER SEES

§1

Why stamp now

A stamp is a timestamped ownership receipt. If curve signatures are ever broken, the earliest matching commitment gives the real seed holder a head start.

§2

How it works

Your wallet signs one fixed message twice. The browser checks that both deterministic signatures match, hashes seedproof-v1 ‖ signature, then writes only that hash to Solana.

Someone with a recovered scalar can forge a valid signature. They cannot reproduce your exact deterministic signature without the seed-derived prefix.

§3

Why we never ask for a seed phrase

Your wallet already knows how to sign. Seedproof never needs, transmits, or stores a seed phrase or private key.

Anyone asking for either is stealing.

§5

Honest limits

Seedproof is a head-start receipt designed to pair with Solana's planned seed-proof migration and the Anza POKOS prototype. It is not a protocol guarantee and is not endorsed by Solana Foundation or Anza. Nothing here promises profits.
