If tomorrow&#8217;s supercomputers manage to crack current private keys, the entire security of <strong>Web3<\/strong> would collapse, leading to a catastrophic scenario. To counter this existential risk, Solana&#8217;s core developers, <strong>Anza<\/strong> and <strong>Firedancer<\/strong> (backed by Jump Crypto), have conducted independent research. Their conclusion is unanimous: the network must adopt <strong>Falcon<\/strong>, an ultra-secure <strong>post-quantum digital signature scheme<\/strong>.<\/p>\n\n\n\n<figure class=\"wp-block-embed is-type-rich is-provider-twitter wp-block-embed-twitter\"><div class=\"wp-block-embed__wrapper\">\n<blockquote class=\"twitter-tweet\" data-width=\"500\" data-dnt=\"true\"><p lang=\"en\" dir=\"ltr\">Solana Selects Falcon Post-Quantum Signature Scheme, Prepares Upgrade Path<br><br>Solana Foundation said its ecosystem has selected the Falcon post-quantum signature scheme following independent research by Anza and Jump Crypto, with an initial implementation completed. The foundation\u2026 <a href=\"https:\/\/t.co\/No1lM3Ohcx\">pic.twitter.com\/No1lM3Ohcx<\/a><\/p>&mdash; Wu Blockchain (@WuBlockchain) <a href=\"https:\/\/twitter.com\/WuBlockchain\/status\/2048906564527161535?ref_src=twsrc%5Etfw\">April 27, 2026<\/a><\/blockquote><script async src=\"https:\/\/platform.twitter.com\/widgets.js\" charset=\"utf-8\"><\/script>\n<\/div><\/figure>\n\n\n\n<p>What is Falcon and why choose it? This protocol stands out for its <strong>compact signatures<\/strong>, a vital feature for maintaining the performance of a <strong>high throughput<\/strong> and <strong>low latency<\/strong> blockchain like Solana. Unlike other heavy solutions that could slow down the network and cause a bottleneck in the DeFi ecosystem, Falcon guarantees a seamless transition. The first code implementations are already available on the GitHub repositories of both teams.<\/p>\n\n\n\n<p>This technological foresight sends a strong signal to the market. As preparations for the next <a href=\"https:\/\/investx.fr\/en\/learn\/crypto-bullrun\/\"><strong>bull run<\/strong> <\/a>intensify, reassuring institutional players about the network&#8217;s long-term viability is crucial. Solana proves its ability to innovate without compromising on speed, thereby consolidating its position as a <strong>technological leader<\/strong> against its direct competitors.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" class=\"wp-block-heading\" id=\"a-meticulously-planned-roadmap-to-avoid-chaos\">A meticulously planned roadmap to avoid chaos<\/h2>\n\n\n\n<p>Although the quantum threat is not expected to materialize for several years, the <strong>Solana Foundation<\/strong> refuses to fly blind. It has unveiled a <strong>three-phase roadmap<\/strong> to integrate Falcon without disrupting users.<\/p>\n\n\n\n<p>The first stage focuses on continuous research and performance testing. Then, if the threat becomes imminent, <strong>post-quantum cryptography<\/strong> will be enforced for all new wallets created on the network, preventing any unpleasant surprises.<\/p>\n\n\n\n<p>Finally, the third phase will involve migrating existing wallets to this new security standard. The objective is clear: to avoid any massive market <strong>bug<\/strong> caused by a technical error. Moreover, the Solana ecosystem is no stranger to resilience. Blueshift&#8217;s <strong>Winternitz Vault<\/strong>, a cryptographic primitive resistant to quantum attacks, has already been running smoothly on the <strong>mainnet<\/strong> for over two years.<\/p>\n\n\n\n<p>Developers assure that these modifications will have no significant impact on current performance. By avoiding rushed protocol changes, Solana maintains the stability of its <strong>decentralized infrastructure<\/strong>. This pragmatic approach allows traders and investors to stay focused on price action and <strong>rally<\/strong> opportunities, without fearing a sudden security breach.<\/p>\n\n\n\n<p>Nevertheless, the implementation remains complex and sensitive to side-channel attacks. In short, side-channel attacks do not attempt to crack Falcon&#8217;s codes. Instead, they exploit information leaks that occur during the program&#8217;s execution on a physical computer. If the code is not <strong>constant-time<\/strong>, an attacker with physical or close access to the machine such as a server, hardware wallet, or smartphone can observe these variations and deduce information about the private key. Therefore, this primarily endangers wallets and validator nodes rather than the signatures themselves.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" class=\"wp-block-heading\" id=\"what-is-the-impact-on-sol\">What is the impact on SOL?<\/h2>\n\n\n\n<p>On a fundamental level, this preemptive upgrade is an <strong>extremely positive catalyst<\/strong>. By removing the quantum risk from the equation, Solana becomes one of the most future-proof blockchains on the market. This narrative could attract <strong>massive capital<\/strong>, especially since <strong>spot ETFs<\/strong> and institutional products demand flawless long-term security guarantees.<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img decoding=\"async\" width=\"1024\" height=\"764\" src=\"https:\/\/media.investx.fr\/wp-content\/uploads\/sites\/5\/2026\/04\/28102417\/SOLUSDT_2026-04-28_09-30-48-1024x764-1.jpg\" alt=\"Solana price chart over two weeks with order blocks\" class=\"wp-image-28693\" srcset=\"https:\/\/media.investx.fr\/wp-content\/uploads\/sites\/5\/2026\/04\/28102417\/SOLUSDT_2026-04-28_09-30-48-1024x764-1.jpg 1024w, https:\/\/media.investx.fr\/wp-content\/uploads\/sites\/5\/2026\/04\/28102417\/SOLUSDT_2026-04-28_09-30-48-1024x764-1-300x224.jpg 300w, https:\/\/media.investx.fr\/wp-content\/uploads\/sites\/5\/2026\/04\/28102417\/SOLUSDT_2026-04-28_09-30-48-1024x764-1-768x573.jpg 768w\" sizes=\"(max-width: 1024px) 100vw, 1024px\" \/><\/figure>\n\n\n\n<p>Technically, the SOL token is showing signs of weakness and bearish divergences.
