Solana unveils stepwise Falcon quantum-signature upgrade while validators test builds; SOL trades around $85

The Solana Foundation published a blog setting out a step‑by‑step roadmap to address potential quantum computing threats, arguing networks should study the issue and prepare early even though the risk is still considered distant. Coinpedia and other outlets summarized the plan around a Falcon post‑quantum signature upgrade as the core mitigation approach ^{[1] [2]}.

Validator clients Anza and Firedancer have rolled out an experimental Falcon signature system aimed at resisting quantum attacks, and coverage describes the overall transition as phased to allow staged adoption and testing across the network ^{[3] [4] [1]}.

Market reports note SOL was trading near $85 after roughly a 2% decline, remaining inside a trading corridor between an $82 floor and an $89 ceiling; analysts also pointed out that the 50‑day and 200‑day moving averages sit above the spot price, a pattern described as bearing bearish undertones ^[3].

The Foundation frames the Falcon rollout as a precautionary, phased and experimental effort to bolster signature schemes ahead of any practical quantum risk, while validators and markets monitor implementation and price action ^{[1] [3]}.
