A sufficiently powerful quantum computer could, in theory, derive private keys from exposed public keys and authorise transactions without the owner’s approval. The U.S. National Institute of Standards and Technology describes this as a future risk and has already standardised algorithms designed to resist quantum attacks.\nHoskinson said quantum computing would test whether Bitcoin can change without weakening the qualities that support its value. He said BTC may not remain the leading cryptocurrency if its governance cannot make progress. However, he did not name another network that would replace it or give a date for a threat.\nBitcoin developers are already studying migration options\nBitcoin has no formal onchain voting body. Developers can propose code, but users and node operators decide whether to run it. Miners, exchanges and wallet providers also influence whether an upgrade gains enough support. This slower process avoids frequent rule changes, though it can make urgent coordination harder.\nWork on quantum resistance is already active. Bitcoin Optech has tracked BIP 361, which outlines a phased move away from current ECDSA and Schnorr signatures after developers select a post-quantum system. Other proposals cover new address formats, hybrid signatures and recovery paths. These ideas remain under review.\nAny such change would also need wallets, exchanges, custodians and long-dormant holders to migrate funds without splitting the network or creating conflicting ownership rules during a limited transition.\nSome researchers estimate that millions of BTC sit in addresses whose public keys are visible. Those coins could face greater exposure if a capable quantum computer appears. The timing remains uncertain, and researchers continue to debate which coins should move, freeze or remain spendable.\nCardano points to formal onchain governance\nCardano completed its move to full community governance through the Plomin hard fork in January 2025. ADA holders can vote directly or delegate voting power to representatives known as DReps. Stake pool operators and a constitutional committee also take part in selected decisions. The system can approve hard forks and treasury withdrawals onchain. \nHoskinson said Cardano could use that structure to vote on a migration away from quantum-vulnerable infrastructure. Yet Cardano has not completed such a migration. Its governance system must still evaluate technical designs, approve funding and organise users, developers and service providers around any change.\nThe process has also produced disputes.Cardano delegates rejected or challenged several proposals linked to Hoskinson and Input Output during 2026. One request included research into Leios scaling and quantum-resistant cryptography. Formal voting does not guarantee approval of a founder-backed plan.\nCardano prepares scaling work alongside security research\nHoskinson also said Cardano is preparing for its largest upgrade and claimed the network would become “60 times faster.” Development updates show teams are testing Ouroboros Leios, a design intended to increase throughput by separating block roles and allowing more work in parallel. Developers continue to integrate the prototype with Cardano node software. \nThe 60-fold figure remains Hoskinson’s estimate rather than a measured result from the live network. Leios still requires testing, technical review and governance approval. Cardano’s recent van Rossem hard fork shows that DReps, stake pool operators and the constitutional committee can coordinate an upgrade.\nHoskinson described Cardano as a “spiritual successor” to Bitcoin because it keeps a fixed-supply monetary model while adding smart contracts and formal governance. Bitcoin supporters may reject that comparison, since Bitcoin’s limited change process forms part of its security model. Bitcoin depends on broad offchain consensus, while Cardano records many decisions directly onchain.\nThe quantum issue remains open for both networks. Bitcoin developers are designing migration options, while Cardano is funding research and building governance tools. Neither network has deployed a complete post-quantum transaction system. The practical test will come when developers agree on secure cryptography and communities must decide how to move users and funds.\n\n\n\n\n\n                Read more:\n            \n\n                XRP Ledger adds $2.6B as RWA inflows rank second","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":"4.46.0","shortVersion":"4.46.0","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/2654065599","isCrawlerRequest":true}
