Anthropic 宣布要彻底切断了所有未经授权的二级股权销售渠道,包括 SPV、远期合约甚至是代币化债权。看到了一个分析,说这背后的逻辑是,公司要夺回 IPO 的定价主权。如果二级市场提前流出了疯狂的隐含估值,就会破坏公司在 IPO 轮次的议价能力,让中间商卷走稀缺性溢价。 Anthropic 这种做法让很多映射了真实股权的链上 pre-IPO 资产交易平台挺难受的,将来这些映射了真实股权的链上资产怎么确权成了问题。但是同时,也让通过永续合约做「合成资产」来做 pre-IPO 资产交易的平台更值得关注了。既然你不让卖股票,那大家就直接交易价格预期,用这种完全脱离实物、基于现金结算的合成敞口,让发行人的禁止令鞭长莫及。 这种东西是否真的有效、真的能做价格发现或者拿到定价权,马上要 IPO 上市的 Cerebras (CBRS)就很值得观察了。 TradeXYZ 在 Hyperliquid 上推出的 Pre-IPO Perpetual (IPOP) 产品,可以交易 CBRS,应该是目前最好的观察窗口。 - 估值背离:目前 CBRS 的 IPOP 标记价格大概超过 290 美元,隐含估值近 800 亿美元。 - 溢价惊人:看新闻说,Cerebras 已将 IPO 指导价上调至 150-160 美元,但链上合成市场的定价仍高出 77% 以上。 - 不过交易量看着不是很大。 Cerebras 应该是 5 月 14 日正式登陆纳斯达克,到时候就可以重点观察: 这种永续合约定价的链上市场是否具备前瞻指标性?还是说,交易者仅仅是为了抢先获得这种无法触达的资产而支付了过高的准入溢价? 按照 TradeXYZ 的机制,一旦 CBRS 开始公开交易,合约将转换为由预言机定价的永续合约,到时候就会是链上原生定价 vs 传统金服定价的一次正面硬刚。我个人非常希望,在未来,真正的价格拍卖不再发生在上市公司和华尔街大佬路演的五星级酒店里,而是在链上的黑暗森林中。

还可以对比一下 Tempo 的设计: - 在 Tempo 上,没有原生代币,费用以美元计价。 - 也没有原生 gas 代币,gas 费用以美元计价,可以使用稳定币支付。 - 整体设计上,主打 gas 抽象/代付,fee sponsorship 让服务端可以帮用户代付 gas。 - 如果钱包界面显示了一个类似原生币的位置,那只是兼容历史钱包习惯的 placeholder。Tempo 文档的说法:「从历史上看,区块链钱包一直默认每条区块链都有原生 gas 代币。但在 Tempo 上,并没有原生 gas 代币,因此所显示的数值只是一个占位符。」

Circle 在公布季报的同时,公布了自己做的 EVM 链 Arc 的 2.22 亿美元的融资信息(估值 30 亿美元),并且明确说明:完成的是代币融资。也就是说,这条链会发币,这让 Circle 成为首家进行代币预售的上市公司。 在这之前,Arc 的文档中写的很清楚:Arc 链 gas 用的是 USDC。 那这个即将推出的 ARC 代币是干什么用的呢? 看了看刚公布的白皮书:ARC 被设计成整个 Arc 系统的「原生协调资产」,也就是,通过 staking 确保链的安全、通过 ARC 代币获得平台权益、获取协议费收入的价值捕获、参与经济治理等等。 这是现在流行的稳定币公链的两层代币模型设计:USDC 负责做 gas 来「使用链」;ARC 负责「拥有链、协调链、治理链、分享链的增长」。 ARC 代币经济的信息: • 初始供应量 = 100 亿 • 早期通胀率预计约为每年 2–3% • 通胀率随时间递减 • 长期目标 = 通胀中性 • 25% — Circle(基金会/核心团队) • 60% — 生态系统(代币销售、开发者资助、网络增长计划等) • 15% — 长期储备

今天有个机会和 John Collison 简单交流,我正好问了他这个问题:第一波真正有可能规模化的 agent 支付用例会是什么。他觉得会是那些针对开发者的产品和服务,比如说调用 API 、购买云服务等等,过去这些都要开发者去注册、购买,但实际上这些更适合 agent 自己去支付。
wispig@wispig66

@fishkiller 对于agent来说,现阶段有哪些支付场景呢

Stripe 推出了可以让 agent 使用的 Link 钱包,因为,过去这段时间他们发现, CLI 用户(应该就是那些用命令行来做支付的用户?)增长速度太快了,是时候让 agent 拥有自己的钱包了。 Stripe 产品与业务总裁 Will Gaybrick 说的很幽默:如果人工智能能攻克诺贝尔难题,却连域名都买不了,那肯定不对。 现在好了,从今天起,大家可以授权自己的 agent 使用 Link 来做支付了。(我看背后方面大部分是 Privy 的功劳)。

非常清晰的信号:Polymarket 要离开 Polygon 了。可以开个市场,猜一下它要迁移到哪里去了。
Josh@devjoshstevens

This is my 3rd week as VP of Engineering DeFi at @Polymarket , and I'm going to be straight: the traction @Polymarket has seen has massively outpaced our infrastructure, and we haven't done nearly enough to scale to keep up. I hear you, and fixing this is our entire focus. We're a major company now, and we need to engineer like one. Here's exactly what we're doing: - Onchain data latency. We're working on making this near-instant so the experience is incredible. - Chain migration. We need more block space, cheaper gas and much smaller block times so settlement is instant. - Transactions are getting cancelled. We understand this is one of the most frustrating issues right now, and we have a complete fix coming very soon. - Massive focus on the website to make it faster, more responsive, and with better UX. - We added observability everywhere. Proper alerting so we catch issues ourselves, market makers should not be the ones telling us something is down. That's been unacceptable, and we know it. - E2e tests throughout, starting with the CLOB, so issues get caught in CI before anything ships. - CLOBv2 is not a rewrite. It won't improve performance or stability on its own; it's an upgrade that unlocks us to move fast right after. We'll do better with communication next time. - We are rebuilding the CLOB from the ground up. Most important thing we're doing. Without it, we can't be the best DeFi exchange in the world. We know it, we're on it, it's mission critical. - Unified TypeScript SDK for all APIs, which is shipping soon. - Unified API. One WS connection for everything, with a schema that's actually readable. - New Polymarket contract in the works that unlocks things that are simply impossible on the current protocol. - New hires: Head of QA Automation, Head of Dev Tooling, Head of Internal Tooling, Head of Data Engineering. - Smaller, dedicated teams. Fewer focus points per person, clearer ownership. People do what they're good at and are accountable for it. - Working closely with customer support to give them real debugging tools so any user issue gets properly diagnosed, not lost. - Proper communication with marketing and market makers so everyone knows what's coming and when, and MM can submit feature requests with a clear path to get them into engineering and shipped. - Working with 4 security teams daily to ensure we're super secure and that funds are always safe. - Perps incoming. Brand new contracts and a backend built from scratch in Rust. We're proud of this one. - A lot of other fixes are running in parallel right now. Starting next Friday, I will be posting weekly engineering updates. I joined because I genuinely believe in what @Polymarket is trying to do. @shayne_coplan built this so the world has somewhere to go to find out what's actually going to happen, not what the media thinks, not what a pundit says, but what thousands of people are willing to put money on. But right now, our engineering isn't living up to that. We've let people down, and I'm not going to dress that up. I came here to fix it, and that's exactly what we're going to do. The next few months are going to speak for themselves. Stay with us.

AngelList 创始人给 USVC 画了画重点(费、核心优势、可能风险等等等等)。 我看到的重点是:USVC 还没有准备好大规模接受国际投资者,但,正在努力。
Nivi@nivi

I spent the morning digging into USVC fees. TLDR: In my opinion, there is no lower-cost way to invest in VC other than becoming one. I’m expecting to pay the same or less than it costs to invest in a good VC fund. And a lot less than investing in a fund-of-funds. All while getting the benefits of a fund-of-funds that can do direct, secondary, and fund investments. Carry. If USVC invests in a fund or SPV, I will pay that manager’s ~20% carry. That’s what I expected. All fund-of-funds do it this way. I’m glad to pay carry to invest with good managers. USVC doesn’t charge additional carry. Direct investments. There is no underlying carry on USVC’s direct investments and they aim to make this a major portion of the portfolio. This would bring down the blended cost of USVC substantially, compared to a VC fund. Fees. The annual fee in the first year is capped at 2.5%. This includes the fees of the underlying funds that USVC invests in, which is a huge deal. Just investing in a VC fund costs 2-2.5% a year. Also, the fee would be 3.6% but AngelList is subsidizing it in the first year. There’s a possibility the annual fee could go up in the future and I’ve told the team that this is extremely confusing and weird, and they are working on it with haste. Overall, I’m expecting to pay the same or less than it costs to invest in a good VC fund, but I’m actually getting access to a fund-of-funds that can do direct, secondary, and fund investments. A typical fund-of-funds charges another 1/10 (fees/carry) on top of the VC’s 2/20, for a total of 3/30. Some other things I learned: Early-stage. Early-stage deals are planned. I would rather invest now in case those early-stage investments get marked up quickly. These deals will be riskier and more illiquid, so there’s no free lunch here. The current portfolio includes late-stage (OpenAI, Anthropic, xAI) and mid-stage (Sierra, Vercel, Crusoe, Legora). Illiquidity. This is venture capital. The underlying investments are illiquid. Don’t invest if you’re uncomfortable with illiquidity. That said, USVC is working on redemptions of up to 5% of the fund every quarter. It’s not guaranteed, but if it’s offered, you can choose to get partial liquidity along the way. International. There is a lot of demand from international investors. USVC is not yet set up to accept international investors at scale, but they’re working on it. Sales load. There is no sales load. USVC is only available on usvc dot com and the sales load is waived if you buy through the site. In the future, brokers that list USVC may charge up to a ~3% sales load; that’s how they make their money. Disclosure: I’m a co-founder of AngelList and have shares in the business.

毫无疑问在这个春天我再次被北京斩杀了,原来不止北卡北欧有斩杀线,北字辈的都有一定的危险在。我还记得刚来北京第一年,和姑娘在学校的花粉雨和沙尘暴里面穿行,她眼睛越来越红我则一直打喷嚏,不知道是互相过敏还是互相挂念,后来也跃入人群不知所终。 若干年后的这个春天则多了某种滑稽感,可能是我越来越成年人了,一回北京吸食柳絮之后即刻倒下(OD了应该是),在家里面冷得打摆子,梦到三个印度人围着我教我说印度语,叽里呱啦的,床上坐起来印度语也没有停,以至于我怀疑单身公寓隔壁可能在拍摄三傻大闹宝莱坞。 终于忍不住了去医院挂急诊,医生先是抱怨我血管质量像个老头找不到入手点(有人说我是少年感的爹或是此因),然后又说我水喝得太少了。我大惊:明明一天喝了几大瓶挂逼怡宝,怎么还不够。医生翻了个白眼,说这个摄入量计算公式是按照质量x超过常温的温度来计算的,以此度之本人担任一匹硕大的烤全马毫无问题。我终于接受自己是个绝望的胖子,抽血等结果时在过道困得不行,唱起了春天里。

Haseeb 讲了讲 Arbitrum 怎么在技术上剥夺了黑客的资产: Arbitrum 安全委员会使用紧急权力注入了一个 ArbitrumUnsignedTxType,强制将攻击者的全部 30,765 ETH 从中心地址转移到一个协议控制的恢复接收地址。 所谓的 ArbitrumUnsignedTxType,只有链本身(通过 sequencer / ArbOS 升级路径,由 Arbitrum 安全委员会控制)才能注入。它完全绕过了攻击者的私钥。 也就是说,安全委员会使用了一个特权的状态覆盖交易类型(这是 ArbOS 的一部分,但基本上从未使用过),让攻击者的私钥仍然可以签名交易,但该地址的 ETH 由链本身转移了。
Haseeb >|<@hosseeb

Claude explains the $71M @arbitrum clawback: What this transaction is Tx: 0x5618...0f6b on Arbitrum, block 454686044, April 21, 2026 03:35 UTC From: 0x5d39...7Ccc — labeled on Arbiscan as “Kelp DAO Exploiter 1” To: 0x0000000000000000000000000000000000000DA0 — a special system/recovery sink (not the normal 0x...dEaD burn address) Value: 30,765.667 ETH (~$71M) — effectively the entire Arbitrum-side balance of the attacker’s hub wallet Tx type: ArbitrumUnsignedTxType (EIP-2718 type 0x65 / 101) The “type 101” is the key. That is not a user-signed transaction — a normal EOA physically cannot produce one. ArbitrumUnsignedTxType is an ArbOS system transaction that only the chain itself (via the sequencer / ArbOS upgrade path controlled by the Arbitrum Security Council) can inject. It bypasses the attacker’s private key entirely. The remediation (this tx): Arbitrum’s Security Council used its emergency powers to inject an ArbitrumUnsignedTxType that forcibly moved the attacker’s full 30,765 ETH from the hub address into a protocol-controlled recovery sink (0x...0DA0). Why it’s “extraordinary” Arbitrum did not perform a reorg or historical rewrite — the chain’s ordering is intact. Instead, the Security Council used a privileged state-override transaction type that is part of ArbOS but has essentially never been used before. It is functionally a state-level clawback: the attacker’s private key still signs txs, but that address’s ETH was moved by the chain itself. This is the mechanism Arbitrum’s progressive-decentralization docs reserve for “catastrophic” emergencies (12-of-N Security Council action), and this is one of the clearest public demonstrations of it being invoked. Note that it only recovered the Arbitrum leg of the theft — the ~75,700 ETH on Ethereum is outside Arbitrum’s control and remains with the attacker, which is why Aave is still facing up to ~$230M of potential bad debt on the Ethereum side. Sources: Arbiscan tx: arbiscan.io/tx/0x561804424… Arbitrum Docs — ArbOS / Sequencer forced inclusion: docs.arbitrum.io/run-arbitrum-n… Arbitrum Foundation — progressive decentralization & Security Council: docs.arbitrum.foundation/state-of-progr…

拉黑,罪名:被买稿当枪手使
Rachel🥥@Zesee

开源圈最近爆出了一个大瓜,我仔细扒完了 Evolver 团队发布的这篇深度拆解博客evomap.ai/zh/blog/hermes…,把这两个项目的仓库翻了个底朝天,帮大家理清这起抄袭风波背后的蛛丝马迹。   先看时间线,这是最硬的锤。   Evolver 早在 2026 年 2 月1日就开源了,连带着那套核心的 GEP 协议也全盘托出。而 Nous Research 的 Hermes Agent 呢?直到 3 月中旬才上线。   这中间足足有一个多月的空窗期,在瞬息万变的 AI 圈,这几乎是半个世纪了。   当时在 GitHub 搜自进化 Agent,Evolver 是唯一的头部,要说大厂团队没看过,那真的很难让人信服。   再聊聊技术架构,如果说英雄所见略同,那这相似度也太高了。   Evolver 提出了三层资产体系和三层记忆体系,Hermes 换了个皮,但层级逻辑和语义划分简直是 1:1 像素级复刻。最离谱的是那个 10 步进化的主循环,从加载、评估到最后的持久化,每一步的编排顺序都一模一样。   虽然代码从 Node.js 换成了 Python,但这种底层的工程决策,比如原子写入、多维加权评分、约束门控模式,全都对上了号。   我把两者的核心概念做了一个对比,大家可以直观感受一下这种系统性的概念替换(见下图)。  最让我感到不平的是零归属。 Hermes 团队在文档里引用了学术界的论文,也提到了其他大厂的项目,但唯独对这个在架构上给他们提供无限灵感的独立开发者项目 Evolver 闭口不提。   这种换汤不换药的搬运,确实伤害了开源社区的根基。
