Even so, the authors argue that uncertainty around future advances in quantum computing warrants early planning to avoid disruption later.\nAt the center of the discussion is the growing debate over Bitcoin held in addresses protected by existing ECDSA and Schnorr signatures. According to the report, some community members support establishing a migration deadline after which those signature schemes would no longer be accepted, effectively freezing coins that have not moved to quantum-resistant addresses. \nSupporters of that approach argue it would prevent future quantum attackers from gaining control of large amounts of BTC and potentially affecting the market.\nOthers within the Bitcoin community take the opposite view. As outlined in the report, critics argue that rendering coins unspendable would amount to confiscation of private property and would conflict with Bitcoin’s long-standing principles of immutability and user control over assets.\nThe report leaves the governance decision to Bitcoin users\nRather than endorsing either position, Coinbase’s advisory board said the question of whether vulnerable coins should eventually be frozen, burned, or left untouched must be decided by the Bitcoin community itself.\nInstead of backing any of the competing proposals, the authors declined to recommend a preferred outcome for legacy Bitcoin holdings.\n\n“We refrain from providing any specific recommendation regarding the treatment of vulnerable coins.”\n\nOn the governance question, the report argued that the final outcome should emerge through Bitcoin’s consensus process rather than being dictated by a small group of researchers.\n\n“The decision should be made by the Bitcoin community.”\n\nSeveral figures cited in the report illustrate why the debate has become increasingly significant. According to the advisory board, roughly 1.7 million BTC are held in older pay-to-public-key addresses whose public keys are already exposed, making them potentially vulnerable to future quantum attacks.\nThe report notes that many of those coins are believed to belong to lost wallets, including holdings commonly attributed to Bitcoin creator Satoshi Nakamoto.\nDrawing on research from Project11, the report also notes that as many as 5 million BTC could face exposure through address reuse, although a substantial portion of those holdings are believed to remain under the control of active users and institutions.\nTechnical proposals are already being explored\nAlongside the debate over legacy coins, the report outlines several proposals designed to ease Bitcoin’s eventual transition to quantum-resistant security.\nOne proposal, known as Hourglass, would limit how many BTC from vulnerable addresses could be moved in each block, reducing the risk of a sudden influx of recovered coins entering circulation. Another proposal, BIP-361, would allow users to prove ownership through post-quantum cryptographic methods even after legacy signatures are retired.\nThe report also discusses Post Quantum Address Commitments, or PACTs, a mechanism that would let users commit to future quantum-safe addresses before a migration deadline without immediately moving funds on-chain.\nWhile the advisory board stopped short of recommending any single solution, it delivered two clear conclusions. According to the report, development of quantum-resistant migration tools should begin immediately, and Bitcoin users should receive clear information about potential risks and available migration paths well before quantum computing becomes a practical threat.\nThe publication comes as Coinbase pursues a wider expansion of its platform, with the company recently outlining plans to integrate trading, lending, payments, derivatives, and AI-powered services into a unified financial ecosystem.\n\n\n\n\n\n                Read more:\n            \n\n                Anthropic shuts down Fable 5 access after US intervention","kind":"highlight","is_publish_news":true,"is_publish_highlight":false,"is_publish_live":false,"is_publish_wemedia":null,"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":"4.44.0","shortVersion":"4.44.0","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/2643242211","isCrawlerRequest":true}
