Key Takeaways: Anza and Firedancer independently selected the Falcon post-quantum signature scheme for Solana, with code on Github. Blueshift’s Solana Winternitz Vault has been live for over 2 years and was cited by Google Quantum AI in 2025. Solana’s 3-step quantum roadmap can activate quickly when needed, with no meaningful performance impact expected. Solana Ecosystem Runs 2-Year Quantum-Safe Vault as Falcon Gains Developer Backing Quantum computing poses a long-term risk to the cryptographic systems that blockchains depend on. At a sufficient scale, quantum machines could break the digital signature schemes that secure wallets and transactions. For most networks, that risk …
