Prove a claim is real
A recycled-content claim points to its batch, mill and transfer history. The submitted evidence and every named holder stay tied to that claim, so a buyer can inspect the record. The issuer still has to establish that the original evidence is true.
“Trust us” cannot carry a market.
Carbon markets suffer from double-counting, opacity, and greenwashing, and the reason is structural: a buyer usually cannot independently verify what they purchased, where it came from, or whether it was already sold to somebody else. The submitted evidence and the transfer history are both there for a buyer to inspect; the issuer still has to substantiate the original claim.
Middlemen, ratings and audits add cost when the evidence is scattered. The issuer, the source evidence, every transfer and the retirement stay connected, so a buyer can inspect the claim's history. The quality of the original claim still depends on who supplied and verified that evidence.
Four steps, and retirement is final.
Issue on the ledger
The issuer identifies a batch of recycled pellets and links the mill's supporting evidence. That becomes a record later holders can inspect.
Bind it to its rules
Who may hold it, how it transfers, what retiring it takes. Your rules, not ours.
Track every transfer
Every hand it passes through is on the record.
Record retirement
Retired once and it cannot come back.
What keeps the claim attached to evidence.
Origin, evidence, current holder, still valid. A buyer needs all four and usually gets a PDF.
Carbon credits
Your credits are issued, tracked and retired in one place.
Agreements
Your rules on who may hold and how it retires.

The same proof can follow products and assets.
A credit and a pump need the same three proofs: origin, every change since, and an owner you can check.
