Put a prediction, claim or piece of work on the record with a timestamp nobody can edit, delete or backdate. When the moment comes, your password proves it was you. No screenshots, no "trust me".
"This startup ships a self-driving scooter before the end of 2027. Screenshot this."
Example of what anyone sees when you share your proof link.
No sign-up, no wallet, no fees. Checking a proof needs nothing installed either.
Your prediction, your claim, your lyric, your promise. Whatever you want on the record.
Your password is scrambled on your device and never sent anywhere. Only its fingerprint is sealed with the note.
Anyone can see exactly when it was sealed. When you type your password, it proves the note is yours.
Everyone has had the experience: you said it first, and you can't prove it.
Match scores, market calls, election results, "this will flop". Get the receipts when you're right.
"Final score 2–1, winner scores in extra time."
Lyrics, hooks, poems, story lines. Put a date on your work before it's everywhere.
"Chorus: we were never lost, just early."
Promises to your audience, your team or yourself, with a date nobody can quietly change.
"We will open-source the engine by June."
Seal your answer before the reveal. Settle it with a link instead of an argument.
"The killer is the brother. Calling it at episode 2."
Keda doesn't store your notes on its own servers. They're written to a public blockchain, a shared ledger that thousands of computers keep in sync.
No contract address set. Deploy the contract and update web/config.js.
Only by knowing your password. Anyone can copy the text, but the original record, its timestamp and the password lock stay with the first one.
Then nobody, including you, can prove ownership. The note stays public and timestamped, but the proof is gone. Use a password manager.
No. The text is public by design, because that's what makes it provable. Don't seal anything you wouldn't post.
Keda gives you tamper-proof evidence of what was written and when. It isn't a legal registration or a copyright filing.
Just a password. We pay the network fee for you. If you'd rather not rely on us, you can pay it yourself with a wallet such as MetaMask. Checking a proof needs nothing.
