A risk score to see exposure, a guided… pic.twitter.com/yj4eSbxzrO— BitGo (@BitGo) July 29, 2026\n\nBitGo turns public-key exposure into a wallet metric\nFor common hashed-key Bitcoin outputs, spending reveals the public key needed to verify the transaction. If coins remain tied to that key through address reuse or a partial spend, they could become targets if a cryptographically relevant quantum computer eventually derives private keys from public keys.\nTaproot requires a separate distinction. Its output key is visible when the output is created, rather than only after a later spend. The draft BIP 360 proposal also identifies Pay-to-Public-Key outputs, reused outputs and Taproot outputs as exposed to long-duration attacks under a future quantum scenario.\nBitGo’s Quantum Risk Score gives clients an in-platform measure of exposure across supported wallets. However, the company has not published the score’s formula, weighting system or thresholds. It is therefore a company risk-management measure, not an independent Bitcoin security standard.\nFour controls change how institutions handle UTXOs\nThe new UTXO selection method groups coins by address. When a wallet selects one UTXO from an address, it attempts to include every other UTXO associated with that address. The approach is intended to avoid leaving funds behind after a spend exposes the relevant public key.\nThe Fix Exposed Addresses workflow moves affected funds into newly generated addresses whose public keys have not appeared onchain. Updated defaults are also intended to reduce reliance on address types and transaction patterns that create earlier exposure.\nBitGo said Taproot and Pay-to-Public-Key funds require separate remediation because those formats expose public-key information from creation. The company did not identify support for those remediation paths in the current product release.\nBitGo quoted Blockstream co-founder Adam Back as saying “nobody has a quantum computer that can touch Bitcoin today.” That assessment means the product addresses a future risk rather than an active method of stealing Bitcoin. It also does not change Bitcoin’s signature system or protect the network by itself.\nBitcoin developers are separately discussing BIP 360, a draft soft-fork proposal for Pay-to-Merkle-Root outputs. The design removes Taproot’s key-path spend and aims to reduce long-exposure attacks. However, its authors say faster attacks against keys revealed while transactions await confirmation may require post-quantum signatures.\nBIP 360 remains a draft and has not been activated on Bitcoin. Any network-wide change would still need technical review, implementation, testing and broad adoption across wallets, nodes and other infrastructure.\nOnchain data explains the institutional focus\nGlassnode estimated in May that 6.04 million BTC, or 30.2% of issued supply, had public-key exposure at rest. It classified 1.92 million BTC as structurally exposed through output design and 4.12 million BTC as operationally exposed through address reuse, partial spending or custody practices.\nThe research did not claim those coins can be stolen today. Instead, it measured where public keys are already visible and where better wallet management may reduce exposure. Exchange-related balances represented 1.63 million BTC within Glassnode’s operational category.\nHowever, BitGo and Silence Laboratories tested post-quantum signing inside an institutional custody workflow in May. In related coverage, nine companies pledged $15 million over three years to a Bitcoin security consortium that named post-quantum research as its first focus.\nBitGo has not disclosed how many clients can access the controls, whether they carry separate fees or when support may expand. Institutions can use the tools to review and move exposed balances, while wider protection will depend on future Bitcoin proposals and adoption.\n\n\n\n\n\n                Read more:\n            \n\n                U.S. sanctions Iranian maritime firm over Bitcoin payments","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/2655825715","isCrawlerRequest":true}
