0xarthur.sui@0x_hellopanda·
我来解释一下sui的这两个BUG吧。 先说一下第一个漏洞是怎么来的。 漏洞一:gas计算溢出漏洞 sui推出了稳定币转账免费后,在Gas的计算上出现了问题,导致了溢出漏洞。 Sui 在处理 Gas时,为了节省存储和计算,会对地址的余额做 pruning,也就是把一些不再需要的余额记录清理掉。 但是,当一笔交易因为资金不足,而提前 abort 时,系统仍然对那个地址做pruning。此时地址的余额已经不足了,再去计算gas就会发生一个溢出bug,让执行引擎状态不一致,共识节点无法产生区块。 漏洞二:恶意字符串导致DOS攻击 第一个漏洞使用了一个热补丁修复,第二个漏洞我觉得完全是安全审计部门粗心了。 在sui-indexer-alt-graphql,代码会直接把客户端请求头里的 SDK version拿来作为 Prometheus 的 label 使用。 虽然做了一些简单清理,但没有做白名单限制,恶意客户端可以随意使用各种字符串构造version。比如我们的版本是1.7.2,这个是正常的请求,但是恶意客户端可以随意编辑任意字符串当做版本号。 然后Prometheus 的 label 数量可以无限扩大,直到所有节点的服务器宕机。 目前修复方案是做了一个白名单的验证。 第一次宕机是设计缺陷,那么第二次就是黑客攻击。估计哪个黑客提前开了空单,就是为了给sui弄宕机。 总结:我看你们的代码都是Claude直接vibe coding后提交的,那么庞大的项目,不应该只是完全依靠AI。应该多个AI模型批量检测后,人工做最终校验去提交。
Sui@SuiNetwork

Activity on Sui mainnet has resumed, and transactions are flowing normally. Both today’s and yesterday’s halts are due to the interaction of the 1.72 release, which introduced Address Balances, and gas charging logic. Yesterday’s implemented fix was an interim measure designed to restore functionality to the network while the Sui Core Team worked on a long-term solution. The interim fix had a known issue with a low probability of causing a halt. This morning, the network hit a variant of the known issue and halted. As of now, the long-term solution has been implemented by validators, fully addressing known issues caused by the original bug, and network activity has resumed. A more detailed incident review is forthcoming. Thank you for your patience.

Kamino Intern@kaminointern·
16% APY + @xStocksFi points? yes you can farm airdrops and actually make money at the same time. Step 1: buy $STRCx (11.5% APY) Step 2: loop it 2x on @kamino via STRCx/USDC Multiply strategy Step 3: enjoy your 16% APY + points. for anyone who's never heard about STRC, here's how it works: - STRC is @Strategy's preferred stock. it currently pays an 11.5% dividend yield and has a $100 par value. - @Strategy uses the money raised from STRC to buy more BTC and bets that BTC will outperform the dividend cost. - STRC is already a $10B+ product today, backed by roughly $4 of BTC for every $1 of STRC. by looping STRCx on @kamino, the 11.5% yield can currently be amplified to around 16% APY at 2x leverage. STRC is trading around $99 right now. since there's no redemption mechanism, the market decides the price. maybe it goes lower, maybe it goes back to $100. > if STRC stays below $100 for long enough, @Strategy can raise the dividend to bring in more demand. depending on when you see this tweet, liquidity can get pretty thin on weekends. intern would probably wait until monday before opening a position. -> the good thing is that @kamino doesn't use DEX prices for the oracle. $STRCx pricing comes directly from U.S. equity markets, helping avoid manipulation and wrongful liquidations. there's not much looping liquidity left on @kamino (<$100k) first come, first served.

这是我最重要的信息转发之一。 这篇论文的第一作者是我极为钦佩的人,也是我的好朋友,来自@Tsinghua_Uni 姚班顶尖选手Guowei Xu,现在他在@Harvard 进行人工智能大模型的科研工作。 Guowei这篇论文精准击中了目前LLM搜索的两个致命瓶颈: ① 只有最后一步对错的sparse verification ② 所有候选答案都靠自回归生成,永远困在模型自己概率分布的entropy shell里 由此,Guowei和他的团队提出BES这个全新的搜索框架,引入Forward Evolution,让大模型像生物演化一样思考,打破大模型原有的概率限制,逼它组合出平时根本写不出来的神仙脑洞。同时进行Backward Decomposition,把大任务拆成一堆一眼就能看出对错的子目标。这样大模型在往前走的时候,每走一步都有及时的Dense Feedback,走偏了立刻能纠正。 BES 在理论上成功证明了演化算子能帮大模型跳出思维定势,而倒推法可以指数级减少模型试错所需的样本量。 当目前主流的Post-training提升算法都失效时,BES 依然能带得动并且让模型能力持续输出稳定提升,这无疑是打破了主流算法的天花板,值得许多人关注学习。 我认为,Guowei这篇论文给Agent指明了新路。 对于现在大火的 AI Agent 任务流、多智能体协同来说,这种一边基因重组思路,一边倒推拆解目标的方式,提供了一套更高效、更不容易跑偏的底层搜索算法。 值得一提的是,@Kevin_GuoweiXu 同学不仅在清华姚班极其优秀,他曾经也是2022 年第 52 届国际物理奥林匹克竞赛(IPhO)的世界第一,金牌。他未来会在美国直博,大家可以多多关注follow!

🚀 How should LLMs sample on hard reasoning problems during post-training and inference where direct rollouts rarely produce a correct answer? Best-of-N (e.g., GRPO) and tree search share two limitations: 🔻 Verification signals are sparse 🔻 Candidates stay within the model's own distribution We introduce BES: Bidirectional Evolutionary Search — a search framework that couples forward candidate evolution with backward goal decomposition. ✅ Works for both post-training and inference.

#Stablecoins aren’t just changing payments. They’re reshaping global financial power. In 2025, digital assets reached a tipping point: • Stablecoin volumes ~1% of global money flows • Crypto assets ~1% of global financial assets Still small — but no longer ignorable. Now comes the real shift in 2026: A conflict between #USD stablecoins vs national monetary sovereignty. When businesses and users adopt USD stablecoins at scale: • Capital flows bypass local banking systems • Domestic currencies lose influence • Financial policy becomes harder to enforce This isn’t just innovation. It’s a structural change in how money moves globally. And history shows: When infrastructure shifts — power follows. The next phase won’t be about issuing more tokens. It will be about building trusted, compliant payment infrastructure that connects real-world use cases. That’s where platforms like XREX Pay come in. The full outlook breaks down risks, opportunities, and what 2026 really means ⬇️ 🔗 Read the full industry outlook: xrex.io/blog/industry-… #CrossBorderPayments #DigitalAssets #FinTech #Payments #XREX
