Sealed Chain
Proving since —

Nothing here asks to be trusted — every hash is recomputed in your browser.

Receipts on screen are re-derived automatically. This audits every receipt on the chain, including those not shown.

Device storage: checking…

Unlike a download — a snapshot that goes stale — this keeps a file on your disk that updates itself with every seal. A copy of your chain that does not depend on us.

    1 · Drop any file
    Or paste text. A contract, a photo, a dataset — anything.
    2 · Hashed locally
    SHA-256 in your browser. The file is never uploaded — only its 64-character fingerprint.
    3 · Sealed for 1 tick
    The fingerprint enters the chain. The receipt proves this exact content existed now.

    Live signals —

    Facts that exist nowhere else because they never had a place to live — each one expires, and each one leaves a receipt that does not.

    Public the moment you post. 1 tick mints your receipt — nothing is ever paid to anyone else.

    GOVERNED CHAT

    Every turn is sealed as a receipt on your chain — the conversation cannot be rewritten afterwards.

    Ticks are prepaid, non-transferable meter credits — 1 tick = €0.01, and one tick seals one receipt. Checkout opens in a new tab (Stripe); refresh the wallet after paying.

    AI Passport
    A sealed snapshot of your chain

    Your AI Passport is a sealed snapshot of your chain: how many receipts it holds, where it begins, and the exact tip it stands at right now — one PDF, generated from the chain itself and sealed on the Recognitium chain.

    Record
    Every receipt, counted and anchored to the chain tip
    Anteriority
    Your earliest seal — the date nobody can claim to precede
    Check
    Any receipt re-verifies at recognitium.com/verify — no account

    Hand it to a client, an auditor or a regulator as the cover page of your records. It asserts nothing on its own: every number re-derives from the chain, and anyone can check without trusting us. The chain is the tamper-evident log; the passport summarises it.

    Every receipt on your chain with the offline verification formula — the same export as the Sealed Chain tab.

    Your AI can seal and verify on this chain. It needs two things: where to reach Recognitium, and your key.

    1 · Your key
    --

    Shown masked. Treat it like a password — it authorises every receipt sealed on your account.

    2 · Connect your AI

    Add this to your MCP client (Claude Desktop, Claude Code, or any MCP-capable agent). Your AI can then prove a file, verify a receipt, or check anteriority on its own.

    loading…

    Verification is free and needs no key. Sealing costs 1 tick (€0.01) from the balance in your Wallet.
