ECC is the most popular standard, with Bitcoin, Ethereum, Solana, Cardano, Polkadot, Avalanche, Stella,r and other major blockchains all reliant on it, but with varying implementations.<\/p>\n<p>ECC has been impossible to breach with today\u2019s classical computers. Its discrete logarithm maths problem is hard enough that a normal computer can\u2019t recover a private key from a public key (or more simply, your public key can\u2019t be reverse engineered to reveal your private key). However, quantum computers solve the challenge and can derive your private keys and even forge your digital signature.<\/p>\n<h2>XRPL Now Quantum Ready<\/h2>\n<p>XRPL will now run on CRYSTALS-Dillithium, a new digital signature scheme designed to withstand quantum attacks. While it signs transactions just as ECC would, it relies on lattice-based cryptography for which there\u2019s no known workaround, even with the most powerful quantum computers.<\/p>\n<blockquote class=\"twitter-tweet\" data-width=\"550\" data-dnt=\"true\">\n<p lang=\"en\" dir=\"ltr\">\ud83d\udea8 JUST IN: <a href=\"https:\/\/twitter.com\/hashtag\/XRPL?src=hash&amp;ref_src=twsrc%5Etfw\" target=\"_blank\" rel=\"noopener\">#XRPL<\/a> is pioneering quantum-resistant transactions with Dilithium cryptography, positioning it ahead in blockchain security. <a href=\"https:\/\/t.co\/RuSPtnCsWz\">pic.twitter.com\/RuSPtnCsWz<\/a><\/p>\n<p>\u2014 RippleXity (@RippleXity) <a href=\"https:\/\/twitter.com\/RippleXity\/status\/2004528868494107042?ref_src=twsrc%5Etfw\" target=\"_blank\" rel=\"noopener\">December 26, 2025<\/a><\/p>\n<\/blockquote>\n<p>While CRYSTALS-Dillithium makes XRPL quantum-secure, it comes at a cost. First, the keys and signatures will be much longer (nearly 40 times larger), resulting in higher bandwidth and storage costs. This also leads to blocks filling up quicker and nodes having to relay more data, which could end up in higher transaction fees. Transactions could also become slower, especially for a high-throughput chain like XRPL.<\/p>\n<p>XRPL joins others like Algorand and Solana in testing post-quantum technology. Algorand implemented Falcon, yet another signature scheme relying on lattice-based cryptography. Most recently, Aptos proposed its first post-quantum digital signature scheme under the AIP-137 proposal, as<a href=\"https:\/\/www.crypto-news-flash.com\/aptos-post-quantum-signature-upgrade\/\"> CNF reported.<\/a> The scheme, dubbed SLH-DSA-SHA2-128s, will be rolled out gradually, with users getting the option to either upgrade or rely on slower less secure schemes.<\/p>\n<p>XRP trades at <strong>$1.84<\/strong>, gaining slightly in the past day, despite a <span>40%<\/span> dip in trading volume.<\/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.
