FOR IMMEDIATE RELEASE
LOGAN, UTAH - March 2026
Every hardware wallet on the market today - Ledger, Trezor, Coldcard, BitBox - signs transactions with ECDSA, a cryptographic algorithm designed in the 1990s. The National Institute of Standards and Technology (NIST) estimates that quantum computers capable of breaking ECDSA will arrive in the 2030s. When they do, every Bitcoin address with an exposed public key becomes vulnerable. Every hardware wallet becomes a liability.
The Toshi PQ1 was designed so this transition is built in from the start.
On March 22, 2026, in Logan, Utah, the Toshi PQ1 successfully generated its first ML-DSA-65 cryptographic keypair entirely on-device. ML-DSA-65 is the NIST FIPS 204 standard for post-quantum digital signatures, finalized in August 2024. The 1,952-byte public key and 4,032-byte secret key were created on the device's STM32 chip. The secret key has never left the device and never will.
The claim is self-attesting: the announcement about the device's post-quantum design was signed by the post-quantum hardware wallet itself.
The quantum threat is not theoretical. NIST has mandated that federal agencies begin transitioning to post-quantum cryptography by 2027. The migration timeline for the broader technology industry is measured in years, not months. Hardware wallets are particularly vulnerable because they are designed to store keys for decades - the same timeframe in which quantum computers are expected to become cryptographically relevant.
Many existing hardware wallet ecosystems may eventually need a post-quantum migration path. That migration can introduce operational risk. The Toshi PQ1 was designed around post-quantum signatures from the beginning.
"We didn't build a quantum-resistant upgrade for an existing wallet. We built a quantum-resistant wallet from scratch. The difference matters. An upgrade has a before and after. The PQ1 only has after."

The Toshi PQ1 implements a dual seed architecture: one BIP39 mnemonic for classical Bitcoin keys (ECDSA) and one PQ mnemonic for post-quantum identity (ML-DSA-65). The two seed spaces are cryptographically independent. Compromising one cannot compromise the other. Both are recoverable. Both are anchored to Bitcoin's genesis block via the root PQ hash.
The Toshi PQ1 is not a standalone product. It is the hardware anchor for the Bitcoin Attestation Network - a post-quantum Layer 1 blockchain where every node runs a real Bitcoin node, every block anchors to Bitcoin via Taproot, and verified work can qualify for qBTCTM allocations as rollout expands.
The network's genesis block was produced on January 3, 2026 - the same date as Bitcoin's genesis block, 17 years to the day. The hardware wallet and the network were designed as one inseparable system.
"The PQ1 is not just a hardware wallet. It is the physical proof that post-quantum Bitcoin is real. You can hold it in your hand. The key was generated on the chip in my office in Logan. No laboratory. No corporate R&D budget. Just two brothers and the conviction that someone needed to build this before quantum computers made it urgent."

The following git commits are independently verifiable in the Bitcoin Attestation Network repository:
The attestation document is itself signed with the Toshi PQ1's ML-DSA-65 key, creating a self-referential proof: the capability is demonstrated by the device that produced it. No other hardware wallet on the market generates ML-DSA-65 keys on-device.
The Toshi PQ1 is currently available through the private testnet program. Organizations and individuals interested in early access can sign up at bitcoinattestationnetwork.org.
The Bitcoin Attestation Network is a post-quantum, Bitcoin-anchored Layer 1 blockchain for identity, verifiable credentials, decentralized AI, and consumer-hardware participation. Self-sovereign by design. Every node runs a real Bitcoin node (Bitcoin Core or Knots). Built in Logan, Utah by Anthony Derbidge (Proofnet BTC LLC) and Drew Derbidge (Blockie Talkie LLC).
