BB84

Quantum-born. Quantum-proof. ⚛️ Excited to join the @solrocketpad incubator and build toward a quantum-safe future on Solana. Real quantum hardware. Post-quantum cryptography. One mission: stronger security for the on-chain world. Let’s build. 💙

Binance. Polymarket. Another hack every day. Get off CEXs. Self-custody with Metamask,Phantom or Solflare. But today’s wallet keys won’t survive a quantum computer ,AI Attacks in future . That’s why we built BB84 Falcon smart accounts on Solana: • Falcon-512 post-quantum signatures, verified on-chain (~300k CU) • Keys seeded from a real quantum computer (Rigetti via AWS Braket,IBM), with the job receipt recorded on-chain • 897-byte public key registered once, so only the 666-byte signature travels in each tx • Q-Day switch: irreversible. After it, only Falcon can move funds, even if your Ed25519 key is stolen • One Falcon signature authorizes any Solana instruction: SOL, SPL tokens, memos, calls to other programs • Every signature covers the exact instructions, a nonce, and an expiry slot, so no tampering and no replays • A relayer pays gas but holds no keys and can’t change your request • Other programs can require Falcon approval via CPI (authorize_pq) Don’t trust us, test it. We published a vault owner’s Ed25519 private key. The SOL is still there, because only a Falcon signature can move it. Live on devnet. Audit next, then mainnet. bb84.sh

SIMD-0708 adds 512-bit vector intrinsics to the SVM. We ran the prototype ourselves. On Zen 4, matching the authors' numbers: • Falcon-512 verify: 20,770 CU (scalar today ~183k) • Keccak-f: 988 CU per permutation (vs 11,824) • 64 valid sigs accepted, 128 tampered rejected What it unlocks for bb84 • Our Falcon smart account costs ~298k CU per tx today. With vectors: several post-quantum signatures in one tx (Falcon multisig, Falcon + ML-DSA hybrid) • ML-DSA (FIPS 204) is Keccak-heavy, so it becomes practical in a single tx • qsim, our on-chain quantum circuit simulator, uses i32×i32→i64 multiply-adds, which map straight onto the new ops. Benchmarks coming ⚛️

🔐 Post-quantum accounts on Solana. 🗂️ Key table: each Falcon-512 key is stored once on-chain, with its registration slot and a qproof receipt. That's public proof the key existed then. 🏦 Vault: withdraw with your normal Ed25519 key or a Falcon signature. 🔒 Q-Day switch: irreversible. Once on, only Falcon can move funds, even if your Ed25519 key is stolen. ⚡ Smart account: one Falcon signature runs any Solana instructions (SOL, SPL tokens, other programs) in one tx. A relayer pays the fee. ~298k CU per check, with blueshift's solana-falcon512 verifier. ⚛️ We run jobs on real quantum computers through IBM Quantum (ibm_fez) and Amazon Braket (Rigetti Cepheus-1-108Q), with receipts on Solana. IQM Garnet/Emerald and IonQ Forte are next.

⚛️ Quantum computers run the circuit. Solana checks the answer. We built solana-qsim: a quantum circuit simulator that runs inside a Solana program and scores real QPU results on-chain. 🧪 The demo (devnet): • 5-qubit GHZ circuit, 1,024 shots on Rigetti Cepheus via Amazon Braket • Receipt on Solana: job, circuit hash, counts hash • Our program re-runs the circuit itself and scores the hardware's counts 📊 Result: fidelity 0.70 · XEB 10.2 (ideal 15, random noise ≈ 0) · ~26k compute units 🛡️ Forged "perfect" counts sent straight to the program → rejected on-chain. Random noise posing as a QPU result scores 0.07. Up to 11 qubits in one transaction, 20 across transactions. It's a classical simulation that checks QPU results Code (MIT), with byte-identical builds of the deployed programs: github.com/bb84sh/solana-qsi… Scoring tx: explorer.solana.com/tx/ynsk9…

A Solana program that simulates quantum circuits on-chain: it checked a real Rigetti quantum computer's result against its receipt and scored it (fidelity 0.70), and rejects forged results. 11 qubits per transaction.

Our first quantum-seeded Solana transaction ⚛️ IBM's 156-qubit ibm_fez → 4,096 quantum bits → receipt + random value on Solana devnet. A public challenge (Solana block hash + NIST beacon) set the circuit before the run: predicted 63.0% ones, measured 62.1%. 2s of QPU time. 23/23 public checks pass. Challenge: explorer.solana.com/tx/43FqA… QPU receipt: explorer.solana.com/tx/389gH… Final value: explorer.solana.com/tx/5XBW7…

Building bb84 ⚛️ Our first Solana transaction seeded by a real quantum computer is in IBM Quantum's queue right now. A public challenge (Solana block hash + NIST beacon) is already on-chain. The QPU's bits, its receipt and a random value land on Solana next, verifiable by anyone. Quantum-born. Quantum-proof.
