Solana developers outline plan to protect network from quantum threats
Two of the network’s core developer teams, Anza and Jump Crypto’s Firedancer, have landed on the same solution: a new type of digital signature called Falcon.

What to know:
- The Solana Foundation said in a new blog post that its core developer teams have aligned on a potential post-quantum solution, identifying the Falcon signature scheme and already building early implementations.
- While quantum computing threats remain years away, Solana says it has a clear, phased plan to upgrade wallets and maintain performance if the risk becomes real.
The alignment is notable given Solana’s technical constraints. The network’s high-speed, low-latency design has raised questions about whether more computationally intensive post-quantum cryptography could be adopted without trade-offs. The foundation said, however, that any eventual migration would be manageable and unlikely to significantly impact performance.
The blog post comes as debate intensifies across the crypto industry about whether advances in quantum computing could eventually undermine blockchain security. The Solana Foundation’s position: the risk is real but still distant.
“Quantum is still years away,” the foundation said, adding that migration plans are “well-researched, understood, and ready to deploy.”
