The agency said the timing of a capable quantum computer remains uncertain, but upgrading cryptographic systems across decentralized networks could take years.\nThe first report focuses on cryptocurrency wallets, while the second examines attackers storing encrypted information today for possible decryption years later. Europol did not say current quantum machines can break cryptocurrency security.\nQuantum threats focus on crypto wallet keys\nEuropol’s cryptocurrency report identifies wallet authorization keys as the main potential point of exposure. Many blockchain systems rely on public-key cryptography to prove that a wallet owner authorized a transaction.\n\nJUST IN: Europol warns Bitcoin & crypto wallet keys face quantum risk.• Only exposed public keys are at risk• No timeline projected• Nothing new—no reason to panicDo not reuse addresses! pic.twitter.com/Ig9gB0ZN2X— Bitcoin Archive (@BitcoinArchive) October 7, 2026\n\nA sufficiently capable quantum computer could theoretically use an exposed public key to calculate its corresponding private key. An attacker could then sign transactions and transfer assets without permission, Europol said.\nThe agency drew a distinction between digital signatures and blockchain hash functions. Europol said cryptographic hash functions used for important parts of blockchain security are comparatively resistant to quantum attacks. The report therefore focuses heavily on wallet signatures, public-key exposure and key management.\nIts findings do not predict an inevitable collapse of cryptocurrencies. Europol instead recommends a phased migration toward post-quantum cryptography, with blockchain developers, wallet providers, policymakers and users coordinating future upgrades.\nBitcoin developers are already discussing parts of that problem. Draft BIP-361 proposes a planned migration away from legacy ECDSA and Schnorr signatures after a post-quantum Bitcoin output type becomes available. The proposal remains a draft and has not been activated on Bitcoin.\nAs crypto.news previously reported, related Bitcoin proposals have sparked debate over how users could move vulnerable coins and what should happen to dormant funds that never migrate.\nQuantum security work has already reached crypto wallets\nSome crypto custodians and blockchain developers have started testing post-quantum systems before a practical threat exists.\nBitGo and Silence Laboratories tested post-quantum multiparty computation signing earlier this year. As crypto.news reported, the demonstration used ML-DSA inside an institutional custody workflow to test how quantum-resistant signatures could fit existing wallet infrastructure.\nBitGo later introduced four controls for supported institutional Bitcoin wallets. In related crypto.news coverage, the company added tools for measuring public-key exposure, consolidating outputs and helping users move funds from addresses considered more exposed under a future quantum scenario.\nCoinbase is working on a similar custody problem. Crypto.news reported in September that the company was designing infrastructure capable of supporting different post-quantum signature schemes, since Bitcoin developers have not yet selected a final replacement standard.\nOther networks are pursuing account-level changes. Sui plans optional quantum-safe authentication based on NIST-approved signature schemes, with native post-quantum accounts targeted for mainnet in 2027. As crypto.news reported, the proposal would let users retain existing recovery information while adopting new authentication methods.\nMonad researchers have proposed separating blockchain addresses from their authentication keys. In related coverage, the design would allow keys to change without requiring users to abandon the same account address. The proposal remains under development.\nNIST standards give developers migration options\nEuropol’s recommendation comes after the U.S. National Institute of Standards and Technology finalized its first major post-quantum cryptography standards.\nNIST approved FIPS 203, FIPS 204 and FIPS 205 in August 2024. The standards cover quantum-resistant key establishment and digital signatures.\nFIPS 203 specifies ML-KEM, derived from CRYSTALS-Kyber, for establishing shared secrets. FIPS 204 specifies ML-DSA, derived from CRYSTALS-Dilithium, for digital signatures. FIPS 205 uses the hash-based SLH-DSA signature system derived from SPHINCS+.\nNIST says organizations should begin moving toward quantum-resistant systems now. Its planned transition would deprecate and eventually remove quantum-vulnerable algorithms from NIST standards by 2035, while higher-risk systems are expected to move earlier.\nThe agency continues developing other options. HQC was selected for standardization in March 2025 as another key-establishment algorithm, while FALCON is being developed as a separate digital-signature standard.\nEuropol had already addressed migration planning in January. A report on financial services recommended a risk-based transition that identifies vulnerable cryptography first and prioritizes systems based on their exposure and importance.\nStored encrypted data faces a separate quantum risk\nEuropol’s second Oct. 7 report examines what security researchers call “harvest now, decrypt later.”\nUnder the scenario, attackers collect encrypted information even though they cannot currently read it. They store the material until future computing systems become capable of breaking the encryption protecting it.\nEuropol said the threat is most relevant for information that needs to remain confidential for years, including government communications, medical records, intellectual property and law-enforcement files.\nThe report, developed with University Carlos III of Madrid, says actual exposure depends on the encryption protocols, configurations and key-management methods protecting the data.\nEuropol found no clear evidence that harvest-now-decrypt-later attacks are currently being conducted systematically at scale. Collecting and retaining large amounts of encrypted information would require substantial storage, processing capacity and technical resources.\nLong-lived and high-value information remains the more plausible target under the report’s scenario. Europol recommends removing outdated protocols, reducing unnecessary data retention and testing post-quantum systems before quantum attacks become practical.\nCrypto migration could take years\nThe timetable remains one of the largest uncertainties surrounding quantum threats.\nNo publicly demonstrated quantum computer can currently derive cryptocurrency private keys at the scale required to steal assets protected by modern blockchain signature systems. Europol therefore frames the issue as a preparation problem instead of an active cryptocurrency attack.\nMigration itself could prove difficult because decentralized networks require coordination among developers, wallet companies, exchanges, custodians, miners or validators and individual asset holders.\nLedger CTO Charles Guillemet has argued that Bitcoin’s hardest problem may be migrating wallets and existing funds safely after developers agree on a new signature scheme. As crypto.news reported, dormant coins and users who fail to move assets create extra technical and governance questions.\nGalaxy Digital has committed money to that work. In related crypto.news coverage, the company created a $5 million program in July to fund Bitcoin research covering quantum-resistant signatures, migration tools and security audits.\nEuropol’s recommendation calls for cryptocurrency projects to identify exposed assets first, improve wallet and key-management practices, test post-quantum alternatives and communicate future migration requirements clearly to users.\n\n\n\n\n\n                Read more:\n            \n\n                Circle brings USDC and EURC payments to SAP","kind":"highlight","is_publish_news":true,"is_publish_highlight":false,"is_publish_live":false,"is_publish_wemedia":false,"editions":null,"column":"","sentiment":"0","news_tag":"","news_rank":0,"isVideo":false,"video":null,"symbols":[],"gpt_button":0,"need_auth":false,"need_login_tip":false,"code":"91000000","status":"200"},"commentList":[],"isCommentEnd":true,"newsSizeData":{"likeSize":0,"commentSize":0,"repostSize":0,"favoriteSize":0,"likeStatus":false,"favoriteStatus":false},"APP":{"userAgent":"Mozilla/5.0 AppleWebKit/537.36 (KHTML, like Gecko; compatible; ClaudeBot/1.0; +claudebot@anthropic.com)","isDev":false,"isTTM":true,"isLaohu8Offline":false,"tenantId":"TBGLOBAL","deviceId":"web-server-community-laohu8-v3","version":"4.50.1","shortVersion":"4.50.1","platform":"web","vendor":"web","appName":"ttm","isIOS":false,"isAndroid":false,"isTiger":false,"isTHS":false,"isWeiXin":false,"isWeiXinMini":false,"isWeiBo":false,"isQQ":false,"isBaiduSwan":false,"isBaiduBox":false,"isDingTalk":false,"isToutiao":false,"isOnePlus":false,"isHuaWei":false,"isXiaomi":false,"isXiaomiWebView":false,"isOppo":false,"isVivo":false,"isSamsung":false,"isMobile":false},"href":"/m/news/2673016830","isCrawlerRequest":true}
