Quantum advisory: QSAVE & QKey

Jeremy Ryan serves as an advisor to QSAVE and QKey — two aligned projects tackling the same problem from protocol and wallet directions: making cryptocurrency survive the quantum era.

The problem

Bitcoin, Ethereum, and virtually every major chain rely on elliptic-curve cryptography. A sufficiently powerful quantum computer running Shor's algorithm could derive private keys from exposed public keys. Most proposed fixes demand a brand-new blockchain, a risky migration, or ongoing per-transaction fees — which is why almost nothing has actually shipped.

No separate blockchain

QKey's approach quantum-proofs assets at the wallet or exchange level — on the chains people already use. No new L1, no bridge risk, no fragmented liquidity.

No per-transaction fees

Quantum protection that doesn't tax every transaction. Security as a property of the wallet, not a toll on usage.

Ready to ship

This is built technology with a deployment path, not a whitepaper promising a future mainnet. For exchanges, custodians, and wallet providers, that distinction is everything.

Advisor · Protocol

QSAVE — Quantum Secure Asset Verification & Endowment

A multi-chain protocol for the quantum transition, focused on quantum-secure asset verification and long-horizon asset endowment. Jeremy advises on strategy, community, and market positioning.

Advisor · Wallet Layer

QKey — Post-Quantum Bitcoin Wallet Technology

Wallet-layer quantum hardening for Bitcoin and beyond: hardened HD wallet architecture (BIP39/BIP32/BIP44) designed to migrate to post-quantum signatures without re-seeding or moving funds, plus QD4 — a deterministic confidential watermark linking today's spend authority to a post-quantum authority. Jeremy advises on go-to-market, partnerships, and exchange/wallet adoption.

Who should talk to us about this

  • Exchanges and custodians whose clients will ask about quantum risk before you expect it
  • Wallet providers (software and hardware) planning a post-quantum roadmap
  • Funds and treasuries with long-horizon crypto holdings that must survive a cryptographic transition
  • Blockchain projects evaluating quantum-resistance narratives versus shippable reality
