Beyond the Quantum Threat: Demonstrating Real-World Blockchain Resilience
summary
Claims a live migration of an existing cryptocurrency to NIST-finalist post-quantum algorithms while keeping throughput and interoperability intact, avoiding hard forks by adding a second quantum-resistant signature encoded into transactions via a zero-knowledge proof; prototype wallet-layer retrofit is blockchain-agnostic, reduces block impact, and is undergoing patenting and PoC work with Hyperliquid. Notes practical hurdles: larger keys raise gas fees, block size limits, and ~20–25% of wallets are irrecoverable, QDay estimates ~3–5 years.
