Verify the data
Follow the material, not the claim.
Enter a GreenPrint certificate ID to check it against the public ledger — the material, the verified weight, the GreenPoints minted and the block that sealed it.
How verification works
Proof you can recompute yourself.
⛓01
Every record is chained
Each verified drop-off is sealed into a block whose hash includes the hash of the block before it, all the way back to genesis.
⛓02
We recompute, not trust
When you search, GreenPrint recomputes every hash from genesis. If a single byte was edited, the chain breaks and verification fails.
⛓03
Anyone can audit
No login needed. Certificates, blocks and hashes are public, so recyclers, brands and auditors all check the same ledger.
