# Quantum ID

#

**Status:** Planned · **Group:** Identity & security

## A name only a post-quantum key can move.

**alice.quantum** or **alice.pqc** is a quantum-safe identity, seeded on a real quantum computer. The name is the handle, and inside it sit a Falcon wallet, a Falcon signing key, an optional multisig and the quantum proof of where it came from. Each ID is a Metaplex NFT.

| Field     | Value                  |
| --------- | ---------------------- |
| NFT       | Metaplex Core          |
| Wallet    | Falcon smart account   |
| Signature | Falcon-512             |
| Multisig  | 2-of-3 post-quantum    |
| Seed      | Real QPU run           |
| Proof     | QPU receipt · slot     |
| Price     | {{QUANTUM_ID_PRICE}}   |
| Renewal   | {{QUANTUM_ID_RENEWAL}} |

## Seeded via real quantum hardware

* Every ID is seeded on a real quantum computer, through IBM Quantum or Amazon Braket.
* QPU bits are mixed with randomness from your own device, so no one else, bb84 included, can compute your key.
* The QPU job is recorded on Solana with a bb84 proof receipt (hashes only), linked from the ID.

Security comes from Falcon-512. The QPU gives each ID its origin and a public, auditable record of it. See [Hardware](../hardware.md).

## Six parts, one name

| Part              | What it is                                                                                                                                                                    |
| ----------------- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| **The name**      | alice.quantum or alice.pqc, a child name under roots bb84 holds in the Solana Name Service. Each ID is also a Metaplex Core NFT, so it shows up in wallets and can be traded. |
| **bb84 Wallet**   | SOL and tokens sent to the ID land in a Falcon-512 smart account. One Falcon signature runs any instruction.                                                                  |
| **Signature**     | The ID holds the owner's Falcon-512 key, registered once on-chain, so any program can check a post-quantum signature from that name.                                          |
| **bb84 Multisig** | Optional M-of-N post-quantum keys, for example 2-of-3 across phone, laptop and guardian, for teams and DAO treasuries.                                                        |
| **Quantum proof** | The bb84 proof receipt of the real QPU job that seeded the ID, plus the registration slot that proves the key existed before Q-Day.                                           |
| **Records**       | SOL address, post-quantum key commitment, ML-KEM key for encrypted messages, and an avatar drawn from the QPU shots.                                                          |

## What you can do with an ID

| Action                     | How                                                                    |
| -------------------------- | ---------------------------------------------------------------------- |
| Receive SOL and tokens     | Send to alice.quantum; it lands in the bb84 Wallet                     |
| Spend                      | Sign with your Falcon key; a relayer pays the fee                      |
| Run a team treasury        | dao.quantum with a 2-of-3 post-quantum multisig                        |
| Get encrypted messages     | Others look up your ML-KEM key                                         |
| Prove you're quantum-ready | "Registered before slot X with a PQ key", checkable by any program     |
| Sell the name              | Transfer the NFT, with a post-quantum signature from the current owner |

## The hard part: a quantum-safe NFT

A plain NFT transfer needs only Ed25519, so on Q-Day an attacker could take the name even if the wallet is safe. Quantum IDs gate transfers with a Metaplex Core plugin: a transfer is approved only after a valid post-quantum signature from the current owner.

Before Q-Day, marketplace sales use a hybrid path (Ed25519 and a post-quantum signature). In Q-Day mode only the post-quantum path works.

## Honest limits

* Names resolve through the bb84 app and SDK first; other wallets need to add the resolver.
* .quantum and .pqc are roots in the Solana Name Service, not official SNS top-level domains.
* Fees still need an ordinary Ed25519 payer (the relayer), which never controls funds.
