How a timestamp works

We make a fingerprint of your document and have it recorded on Bitcoin through OpenTimestamps, a free public service. You don't sign anything or pay anything.

It usually completes within a few hours. When it does, you'll get a proof file (.ots). Keep it, along with your original document, exactly as it was. Together they show your document existed by that date, and anyone can check it against Bitcoin.

What a timestamp shows, and what it doesn't. It shows when your exact document existed. It does not show who wrote it, who owns it, or that it is true. It is not an official certification and not a copyright registration. How much weight it carries as evidence depends on where you are and the situation. Change even one character and the proof no longer matches, so keep your original safe.

How to use a crypto wallet

Sealing is paid for with crypto, so you need a wallet. It takes about 10 minutes the first time.

1
Get a wallet extension
Use Chrome, Brave or Edge on a computer. Install one wallet from its official site:

Unisat or Xverse for Bitcoin, Yours for BitcoinSV.
↓
2
Create your wallet
Open the extension and choose “Create new wallet”. Set a password.

Write down the recovery phrase (12 or 24 words) on paper. Anyone who has it can take your money. Never share it or type it into a website. Bitseal and the wallets will never ask for it.
↓
3
Add a little crypto
Buy Bitcoin (BTC) or BitcoinSV (BSV) on an exchange you trust (Bitcoin - BTC: Coinbase, Gemini, Kraken) (BitcoinSV - BSV & Bitcoin - BTC: Swapspace), matching the wallet you chose. In your wallet click “Receive” and copy your address. On the exchange, withdraw a small amount to that address. A few dollars is enough for a text seal.
↓
4
Connect it to Bitseal
When you seal a draft, the Save on-chain box lists your wallets. Click Connect next to yours. The wallet opens: log in, then approve. It turns green when it is connected.
↓
5
Pay and seal
Check the size and fee, then click Pay & seal. Your wallet opens a window showing the amount. Check it, click Sign or Confirm, and the payment is sent.
↓
✓
Wait for confirmation
Your draft shows as pending, then sealed once the network confirms it. Bitcoin can take 10 minutes or more. BitcoinSV is usually quicker.

Anything sealed on-chain is public and permanent. Payments can't be reversed, so check the amount before you sign.

Share to Nostr

Send the transaction ID so the other person can fetch and verify the record.

Note

Publishing is switched off in this demo, so no demo records reach real relays. Copy the note and post it from your Nostr app.

Delete your account?

This cannot be undone.

Your account, your profile and all of your drafts will be permanently deleted from Bitseal.

Anything you have already sealed stays on the blockchain, because no one can remove it. Bitseal will no longer show it in your archive.

Review queue

Drafts held or blocked by the automatic check. The check only flags; you decide. Approve lets the person seal it, Remove hides it, Ban account closes the account.

Before you seal

Sealing is permanent.

A sealed draft is recorded on the blockchain for the public to see. It can never be edited or deleted, by you or by anyone else.

I understand that sealing is permanent and public, and I agree to the Bitseal Terms and Conditions. I will not seal harmful, inappropriate or illegal content.
