The threat is not immediate, Ripple stressed, but it is no longer abstract enough to ignore.<\/p>\n<h2>Ripple says the issue is now operational, not theoretical<\/h2>\n<p>The company\u2019s argument is fairly straightforward. Most blockchains still rely on cryptographic schemes that would become exposed if sufficiently powerful quantum computers arrive. On XRP Ledger, every signed transaction reveals a public key onchain, which means long-lived, high-value accounts become especially important to protect over time.<\/p>\n<p>Ripple also highlighted a quieter danger often described as harvest now, decrypt later. In that scenario, attackers collect public cryptographic data today and store it until quantum hardware becomes capable of exploiting it later. That possibility does not put assets at risk right now, but it does make migration timelines matter more than they used to.<\/p>\n<p>Ripple\u2019s case is that <a href=\"https:\/\/www.crypto-news-flash.com\/xrpl-adopts-quantum-safe-signatures\/\">XRP Ledger<\/a> is not starting from scratch. The network already supports native key rotation and seed-based deterministic key generation, two features the company says could make a <a href=\"https:\/\/www.crypto-news-flash.com\/google-sets-2029-post-quantum-deadline-putting-bitcoins-long-term-security-back-in-focus\/\">post-quantum<\/a> migration more practical than on some rival chains.<\/p>\n<h2>The roadmap stretches from emergency recovery to full migration<\/h2>\n<p>Rather than treating quantum resistance as a single software patch, Ripple laid out a four-phase roadmap. The first phase focuses on Q-Day recovery, including potential mechanisms for moving funds to post-quantum-secure accounts if classical cryptography fails suddenly.<\/p>\n<p>The second and third phases, running through 2026, center on testing NIST-recommended post-quantum algorithms, benchmarking performance and experimenting with parallel signature schemes on development environments.<\/p>\n<p>The final phase targets a full XRP Ledger amendment and ecosystem-wide transition by 2028.<\/p>\n<p>That timeline is ambitious, but it reflects a larger point Ripple is clearly trying to make. The quantum threat may still be years away. The preparation window, in its view, is already open now.s<\/p>\n<p> <a href=\"https:\/\/www.crypto-news-flash.com\/\">Source<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p>All news is rigorously fact-checked and reviewed by leading blockchain experts and seasoned industry insiders.
