He argues<\/span><span style=\"font-weight:400\"> that the m<\/span>ost pressing danger is not stored keys but the information flowing between institutions in real time, further adding:<\/p>\n<blockquote>\n<p>\u201cThe financial system\u2019s most dangerous vulnerability isn\u2019t stored data, it\u2019s the data moving between institutions right now. Every interbank message, every payment authentication record, and every digital signature traveling across a network today is being collected by sophisticated adversaries who don\u2019t need to read it yet.\u201d<\/p>\n<\/blockquote>\n<p>Gault\u2019s warning centers on a strategy security researchers call \u201charvest now, decrypt later.\u201d The idea is that an attacker does not need a working quantum computer today to benefit from one tomorrow. Encrypted traffic can be copied and stored cheaply <span style=\"font-weight:400\">now, then decrypted years later once a sufficiently powerful machine exists.<\/span><\/p>\n<p><span style=\"font-weight:400\">That reframes the quantum threat from a future event into a present-day data-collection problem. Post-quantum cryptography (encryption designed to withstand quantum attacks) only protects information going forward. Anything captured before the upgrade remains exposed to retroactive decryption, which is why Gault and others argue the clock is already running.<\/span><\/p>\n<h2><span style=\"font-weight:400\">Why the Proof Layer Matters<\/span><\/h2>\n<p><span style=\"font-weight:400\">The data being harvested is not just sensitive but foundational, Gault believes. He described the authentication records moving across networks as \u201cthe proof layer that determines who owns what, who authorized which transaction, and who bears legal liability.\u201d<\/span><\/p>\n<p><span style=\"font-weight:400\">If that layer can eventually be decrypted and forged, the consequences extend well beyond individual wallets. Settlement records, signatures and payment confirmations underpin the trust between banks, exchanges and <span>blockchains<\/span>. An adversary able to rewrite or impersonate them in the future could call past transactions into question, a systemic risk rather than a series of isolated thefts.<\/span><\/p>\n<p><span style=\"font-weight:400\">The warning sharpens an uncomfortable contrast because while Ethereum has moved toward a coordinated post-quantum migration, <a href=\"https:\/\/www.binance.com\/en\/price\/bitcoin\" class=\"lar_link lar_link_outgoing\" target=\"_blank\" rel=\"noopener noreferrer\">Bitcoin<\/a> has not adopted a comparable plan. <a href=\"https:\/\/www.binance.com\/en\/price\/bitcoin\" class=\"lar_link lar_link_outgoing\" target=\"_blank\" rel=\"noopener noreferrer\">Bitcoin<\/a>\u2019s transactions are secured by the <\/span><span style=\"font-weight:400\">elliptic curve digital signature algorithm<\/span><span style=\"font-weight:400\"> (ECDSA), a scheme that a powerful enough quantum computer could in theory break.<\/span><\/p>\n<p><span style=\"font-weight:400\">However, timelines are still quite contested as analyst Nic Carter believes that a so-called <\/span><a href=\"https:\/\/news.bitcoin.com\/nic-carter-raises-concerns-on-bitcoins-quantum-vulnerability-q-day-to-arrive-by-2035\/\"><span style=\"font-weight:400\">Q-Day could arrive by 2035<\/span><\/a><span style=\"font-weight:400\">, while other estimates are far more aggressive, placing a code-breaking machine as early as 2027. <\/span><a href=\"https:\/\/news.bitcoin.com\/googles-quantum-advances-bring-bitcoin-security-debate-into-focus\/\">Google\u2019s quantum advances<\/a> have repeatedly pushed the security debate back into focus, as venture investor Chamath Palihapitiya recently warned that non-state actors could one day target <a href=\"https:\/\/www.binance.com\/en\/price\/bitcoin\" class=\"lar_link lar_link_outgoing\" target=\"_blank\" rel=\"noopener noreferrer\">Bitcoin<\/a>\u2019s holdings as a \u201choneypot.\u201d<\/p>\n<p><span style=\"font-weight:400\">And, while developers have grown more vocal after years of relative silence, the prevailing approach still favors voluntary transitions and waiting for mature standards rather than a forced protocol change, a posture that Gault\u2019s comments implicitly challenge.<\/span><\/p>\n<h2>Securing Data In Transit<\/h2>\n<p><span style=\"font-weight:400\">Zerotier is not a neutral bystander in the debate as the firm recently launched <\/span><span style=\"font-weight:400\">Zerotier Quantum<\/span><span style=\"font-weight:400\">, a networking platform built to meet the U.S. government\u2019s highest cryptographic benchmarks, including standards set by the National Institute of Standards and Technology (NIST). Gault\u2019s framing naturally favors securing data in transit, the problem his product addresses.<\/span><\/p>\n<p><span style=\"font-weight:400\">Still, the underlying point is hard to dismiss. If adversaries are already banking encrypted traffic for a future payday, then the window to protect it is now, not on Q-Day. For <a href=\"https:\/\/www.binance.com\/en\/price\/bitcoin\" class=\"lar_link lar_link_outgoing\" target=\"_blank\" rel=\"noopener noreferrer\">Bitcoin<\/a> in particular, the question is whether a community that prizes deliberate, consensus-driven change can move fast enough to defend data that is being harvested while the debate continues.<\/span><\/p>\n<p> <!-- --><\/div>\n<p><a href=\"https:\/\/news.bitcoin.com\/bitcoin-quantum-threat-harvest-now-decrypt-later-zerotier-2026\/\">Source link <\/a><br \/>\n<br \/><\/p>\n","protected":false},"excerpt":{"rendered":"<p>(Originally posted on : Bitcoin News ) Key Takeaways Zerotier\u2019s Andrew Gault says harvested network data is crypto\u2019s top quantum risk.
