Create your own battery passport
and anchor it on Midnight.
In about five minutes you will create a small battery passport, anchor it on the Midnight blockchain and prove a confidential claim about it, without revealing the number. No wallet extension, no tokens, no signup.
Your producer identity
Freshly created for you. Your passport is issued and anchored under this identity.
Your battery passport
Anchoring your passport
Freshly generated for you. The bind step anchors the blake2b-256 hash of exactly this id on-chain, and the explorer will list your passport under it.
This runs live on Midnight preview. Every step with a tx link is a real on-chain transaction.
Done. Your passport is on-chain.
Your confidential CO2 value never left the server. What is on-chain is the passport's anchor and a zero-knowledge proof of the claim, verifiable by anyone.
