Public chains made ownership verifiable by making it observable. One address links every mint, trade, and token-gated login you ever signed into a single permanent record. Anyone can read your portfolio, your cost basis, and your habits, and they can keep reading them forever.
A bond is SHA-256(asset · salt · key): the asset, a 16-byte secret salt and a 32-byte one-time key, hashed in the holder's browser. The hash reveals neither the asset nor the keys. The holder can anchor it in a transaction from their own wallet, and the bond NFT contract carries it as a token and nothing more.
A transfer seals the receipt in an AES-GCM package under a passphrase, stretched with PBKDF2 at 100,000 rounds. The recipient imports it, checks it against its commitment, and re-cloaks the asset under a fresh salt and key, which gives it a new commitment. The sender's old receipt still verifies until the sender discards it, because a hash cannot forget an opening. On the NFT contract, retiring the old bond burns its token and publishes a nullifier, the commitment and nullifier construction Zcash uses.
To show ownership, the holder sends one receipt to one counterparty. The counterparty's browser recomputes the hash on /verify and returns one bit: true or false. The receipt opens that bond and no other.
Salts, keys and receipts stay in the holder's browser storage until the holder copies a receipt or sends a transfer package. The site holds no keys and no funds, and neither contract has an owner, an admin key or a pause switch, so nobody can freeze or seize a bond.
$n0n fair launches on the Pons launchpad on Robinhood Chain. Two contracts tie into it. The bond NFT collection, deployed against the $n0n address, mints only to wallets that hold $n0n. The Uniswap v4 fee hook takes 0.30% of every swap that buys $n0n in its pool, burns 80% of that fee and sends 20% to the prover fund.
Ledger: cloaking, proofs, transfers and verification run in your browser, and nothing reaches a chain until you send a transaction from your own wallet. The bond NFT contract is written and compiled, the v4 fee hook is written, the project has deployed neither, and $n0n is not issued yet.
