Built for creators, founders, researchers — anyone whose credibility lives or dies on being first.
Your idea is hashed, sealed on-chain, and turned into a shareable proof URL. Done before you can blink.
Paste a draft, a prediction, an article — whatever you want to lock in time. Text, file, or URL.
Public for receipts you want to share. Sealed for predictions that auto-reveal on a date you set. Hash-only for total privacy.
Sealed permanently in about a second. You get a proof URL that works forever — independently verifiable, even if we don't.
For proofs that need the ultimate timestamp — anchor them directly in the Bitcoin blockchain via OP_RETURN. Independently verifiable by anyone, forever, using any Bitcoin block explorer. No TruthStamp required.
Create a stamp →Make a prediction now. The content stays hidden but the timestamp is permanently sealed. On the date you choose, your prediction auto-reveals — with mathematical proof the sealed content existed before the reveal date.
Start sealing predictions →TruthStamp is just an interface. Your receipts live on a decentralized verification layer that works without us. Even if TruthStamp shuts down tomorrow, your proofs stay verifiable forever.
