Bond the claim,
not the trust.
A carbon claim is only as good as the trust behind it. Raters disagree, registries get questioned, and a buyer is left to take the number on faith. VPAY makes a carbon claim bonded, challengeable, and recomputable on a public blockchain — accountability anyone can verify, not a number you have to believe.
No verification, no trust.
The market is fleeing claims
it can't verify.
The same project earns a high rating from one house and a low one from another — and not one of them stakes anything on being right. The claim is an assertion, and an assertion is what greenwashing feeds on. As authenticity becomes legally load-bearing, "trust us" stops being good enough.
Ratings without skin in the game
The same project routinely gets contradictory ratings — and none of them bonds its number.
Authenticity is now the law
CORSIA becomes mandatory; Article 6 corresponding adjustments make a credit's integrity a compliance obligation.
A willing payer
Buyers and regulators increasingly will not accept a claim they cannot independently verify.
Accountability, not just a number.
We don't measure or rate the carbon — we make whoever did accountable for it. We prove who stood behind a claim and staked something on it. That is the honest, defensible thing to verify.
Bond the claim
Whoever makes a carbon claim stakes a bond they lose if it is false. Skin in the game, on-chain.
Open the challenge
Anyone can challenge a bonded claim within its window. A successful challenge is rewarded; a false claim is slashed.
Anchor it public
The claim is sealed and written to a public blockchain — permanent, timestamped, tamper-evident.
Recompute it
The proof is open math, not a private database. A buyer, an auditor, a regulator each verifies it themselves.
The math is the audit.
Recompute it yourself.
Every bonded claim becomes a hash written on-chain. Take the claim data, hash it again, and check it matches — right here, in your browser.

SHA-256 over the sample claim, computed locally. The live contract uses keccak-256 over canonical bytes — same principle, recompute and compare.
A neutral rail — for everyone
who touches the claim.
This isn't another rating to argue with. It's the layer that makes any rating, measurement, or credit accountable. Raters are customers, not just rivals — bonding a rating is how it earns the trust the rest can't match.
