Commit first.Reveal later.Verify forever.

The verification layer for committed data and trusted reveals. Pre-commit pack contents, inventory, sealed bids, documents or credentials before a sale — reveal them after purchase — and let anyone independently prove the reveal matches the original commitment.

Committed before sale Anchored on-chain Independently verifiable
How it works

Hidden trust becomes public proof

1

Commit

Before the sale, every pack's contents are hashed, encrypted, and folded into a single on-chain commitment. Nobody can read them — but they're frozen.

2

Reveal

After purchase, the reveal key is published. The buyer decrypts exactly what was committed — the seller cannot swap, edit, or cherry-pick after the fact.

3

Verify

Anyone re-checks the reveal against the pre-sale commitment. Signatures, hashes, and the on-chain anchor all have to line up. No trust required.

Verify a proof

Scan, paste, or type a Pack ID

Buyers don't need to understand cryptography. Enter a Pack ID and we'll show a plain-English verdict — with the full technical and raw cryptographic proof one click away.
