However, many already rely on “k-deep” confirmation rules, which offer no formal guarantees. A transaction in such models is only treated as confirmed once a predefined number of blocks have been added on top of it.\nDevelopers say the rule can be introduced without hard-forking, though client and API integration is still required.\nClient teams are already working on implementations, with deployment expected to allow nodes to adopt the rule without network-wide coordination.\nWhen using FCR, rather than counting blocks, the system evaluates validator attestations to determine whether a block is safe to treat as confirmed. This can solve the issue of slow bridging between Ethereum L1 and downstream platforms.\nIt does this by relying on two assumptions: that validator messages propagate quickly across the network and that no single entity controls more than 25% of staked Ether. While these thresholds fall short of Ethereum’s stricter finality guarantees, they are considered sufficient for most real-world use cases.\nIn cases where more security is needed, the system waits longer before confirming a block, Ma explained, adding that “it’s a feature, not a bug.”\nMixed community reaction\nEthereum co-founder Vitalik Buterin said the mechanism can provide a “hard guarantee” that a transaction will not be reverted after a single slot under the right network conditions.\nBut other community members remained skeptical about the proposal. Some argued that the model leans heavily on trust assumptions and may face challenges under stressed network conditions.\n\n\n\n\n\n                Read more:\n            \n\n                Ethereum ETFs hit three-week high inflows, will ETH price break $2,400?","kind":"highlight","is_publish_news":true,"is_publish_highlight":false,"is_publish_live":false,"is_publish_wemedia":null,"editions":null,"column":"","sentiment":"1","news_tag":"corporation","news_rank":0,"symbols":[],"gpt_button":0,"need_auth":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,"tenantId":"TBGLOBAL","deviceId":"web-server-community-laohu8-v3","version":"4.37.0","shortVersion":"4.37.0","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/2620925567","isCrawlerRequest":true}
