Overview
- Solana Foundation, which published a report Monday, said the network has a researched path to switch to post‑quantum cryptography if the threat emerges.
- Anza and Jump Crypto’s Firedancer each chose Falcon, a compact signature scheme built to resist quantum attacks.
- Both teams have early Falcon code running in tests.
- The roadmap phases in protections with research first, optional support for new wallets next, and later migration of existing wallets, with no immediate protocol change.
- The foundation expects the shift to be manageable because Falcon’s small signatures suit Solana’s high throughput, and it highlighted Blueshift’s two‑year‑old Winternitz Vault that Google Quantum AI recently cited.
