DeFi 新王登场?

marsbitОпубліковано о 2025-09-28Востаннє оновлено о 2025-09-29

Curve Finance 的创始人 @newmichwill 正在推出 @yieldbasis,一个没有无常损失的比特币 AMM 流动性平台(深潮注:IL,无常损失,指当你作为流动性提供者向 AMM 提供资金时,相比于简单持有这些代币,可能会遭受的损失);

同时 @yearnfi 的创始人、DeFi 之神 @AndreCronjeTech 正在构建 @flyingtulip_,一个统一的 AMM+CLOB(深潮注:自动做市商+中央限价订单簿,AMM 提供持续的流动性和自动定价,CLOB 提供更精确的价格发现和订单执行)交易所)。

两种不同的尝试,解决同一个问题 —— 如何让链上流动性真正发挥作用:

  • Yield Basis ($YB): 一种 Curve 原生的 AMM,通过持有恒定的 2 倍杠杆 BTC-crvUSD 流动性池,消除 BTC 流动性提供者的无常损失(LP 的价值与 BTC 保持 1:1,同时赚取交易费用)。用户可以铸造 ybBTC(收益型 BTC)。
  • Flying Tulip ($FT): 一个链上的统一交易所(包括现货、借贷、永续合约、期权以及结构化收益),基于波动性感知的混合 AMM+CLOB 架构,结合滑点感知的借贷机制,以及作为激励核心的 ftUSD(一种 Delta 中性美元等价物)。

Yield Basis

  • 传统 AMM 让 BTC 流动性提供者在价格上涨时卖出,或在价格下跌时买入(√p 敞口,深潮注:以价格平方根为单位来衡量的市场风险敞口),导致的无常损失通常超过了提供流动性赚取的费用。
  • Yield Basis 的具体机制将在后续详细介绍,但核心是:用户将 BTC 存入平台,协议借入等量的 crvUSD,形成一个 50/50 BTC-crvUSD 的 Curve 流动性池,并以 2 倍复合杠杆运作。
  • 一个重新杠杆化的 AMM 和虚拟池会保持债务约等于流动性池价值的 50%;套利者通过维持杠杆恒定来获利。
  • 这使得流动性池的价值线性地随 BTC 变化,同时赚取交易费用。
  • 流动性提供者持有 ybBTC,这是一种收益型 BTC 收据代币,自动复合以 BTC 计价的交易费用。
  • 平台还提供治理代币 $YB,可以锁定为 veYB,用于投票(例如选择流动性池奖励分配)。
  • Yield Basis 主要面向希望在解决无常损失问题的协议中释放生产性 BTC 并赚取费用的 BTC 持有者。

Flying Tulip

  • 传统的去中心化交易所(DEX)的用户体验和风险设置通常是静态的。而 Flying Tulip 通过根据波动性调整 AMM 曲线以及根据实际执行情况/滑点调整借贷的贷款价值比(LTV),目标是将中心化交易所(CEX)级别的工具引入链上。
  • 其 AMM 根据测量的波动性(EWMA)调整曲率——即在波动较小的情况下趋于平坦(接近常和),以压缩滑点和无常损失;在波动较大的情况下更具乘积特性,以避免流动性枯竭。
  • ftUSD 代币化的 Delta 中性流动性池头寸生成,并用于激励机制和流动性计划。
  • 平台代币 $FT 可能用于收入回购、激励和流动性计划。
  • Flying Tulip 是一个 DeFi 超级应用:一个交易所同时支持现货、借贷、永续合约和期权。
  • 执行品质依赖于准确的波动性/影响信号以及在压力环境下的稳健风险控制。

两项目展望

Yield Basis 希望成为 BTC 流动性的平台;而 Flying Tulip 则致力于成为所有链上原生交易的平台。在当前永续合约去中心化交易所(Perp DEX)为主流的时代,Flying Tulip 的推出显得恰逢其时。坦白说,如果能带来最佳执行效果,Flying Tulip 甚至可以将未来的 BTC 流量引流至类似 YB 的资金池。

如果 Yield Basis 成功实现,ybBTC 可能成为比特币的「stETH」原语:BTC 敞口 + 流动性提供者 (LP) 交易费,且没有无常损失。

Flying Tulip 有潜力推出其整合堆栈,让用户获得中心化交易所 (CEX) 级别的工具;尝试「一站式交易,覆盖所有 DeFi」。

尽管对这两个项目保持谨慎乐观态度,但不可忽视的是,这些元老级创始人和顶级团队的项目仍未经过测试,而且创始人还需兼顾其他协议(如 Curve 和 Sonic)的发展。

Deep Dissection of the Anthropic Account Banning Storm: The Behind-the-Scenes of the Safety Religion, AI Civil War, and Claude's Dilemma Under US-China Decoupling

"Deconstructing Anthropic's Account Banning Storm: Safety Dogma, AI Civil War, and the Claude Dilemma Under US-China Decoupling" analyzes the aggressive user account suspension policies of Anthropic, particularly for its product Claude Code. The article attributes this to a multi-layered convergence of factors. The root cause is traced to founder Dario Amodei's personal "safety religion." Shaped by his father's illness and his exit from OpenAI over safety disagreements with Sam Altman, Amodei embedded this "zero-tolerance" philosophy into Anthropic's DNA. This manifests in technologies like Constitutional AI and a "preventive enforcement" approach to risk, prioritizing safety over user experience or growth. This stance defines Anthropic's position in the US "AI Civil War," pitting "safety-first" proponents like Amodei against "accelerationists" like Altman who prioritize rapid development and commercialization. Anthropic's strict model aligns with its business strategy targeting high-value, low-risk enterprise clients who pay a premium for security, unlike OpenAI's mass-market approach. Capital from Amazon and Google supports Anthropic but also creates a delicate balance, as these investors need its safety reputation without allowing overly restrictive policies to cripple its commercial viability. The conflict escalated when Anthropic refused a US Department of Defense contract requiring the removal of safety guardrails, leading to its placement on a "supply chain risk" blacklist—a key example of the public battle between the two AI factions. For Chinese users, the stringent bans are further compounded by US-China tech decoupling. Anthropic's policies act as a tool for compliance with US export controls, making Chinese users—who often circumvent regional blocks via VPNs or virtual cards—primary targets for "preventive" account terminations to avoid regulatory penalties. The article concludes that Anthropic's harsh account control measures are unlikely to loosen in the near future, being integral to its founding philosophy, business model, and geopolitical compliance needs, positioning it as a unique, security-obsessed player in the tripartite global AI competition involving US safety and acceleration factions and rising Chinese AI power.

SpaceX IPO Rush: A Capital Feast That Could Reshape the Landscape of AI and Crypto

SpaceX's potential IPO is emerging as a pivotal event that could reshape the landscape for both AI and Crypto markets. Far more than a traditional aerospace offering, SpaceX represents the core of Musk's future-tech ecosystem, with its Starlink satellite network positioning it as a global digital infrastructure company. This shift could redefine the foundational layers of the internet, communication, and data flow. Historically, major tech capital market movements, like AI booms or Bitcoin ETF approvals, have profoundly influenced crypto cycles. The SpaceX IPO could trigger a similar "super-narrative" fusion, boosting investor sentiment toward future digital infrastructure. This is particularly relevant for Crypto, which aims to build decentralized versions of such global systems. Key crypto sectors likely to benefit include: * **DePIN (Decentralized Physical Infrastructure Networks):** Projects like Render, Filecoin, and Helium, which incentivize real-world infrastructure for compute, storage, and connectivity. * **AI Crypto:** Platforms such as Bittensor and Fetch.ai, which leverage blockchain for decentralized AI computation, data markets, and agent economies. * **On-chain Payments & SocialFi:** Ecosystems like Solana and Ton, which could gain traction if Musk's X platform integrates digital payments and stablecoins. Ultimately, the IPO symbolizes a broader capital re-evaluation of core digital-age assets—networks, AI, data, and decentralized systems—aligning closely with crypto's long-term vision. It may act as a catalyst, redirecting global tech investment flows toward the crypto space as the next chapter in digital infrastructure unfolds.

KUN and Pharos Network Forge Strategic Partnership to Jointly Drive Innovation in RealFi, RWA, and Cross-Border Payment Infrastructure

Hong Kong. Layer 1 infrastructure Pharos Network and licensed digital payment expert KUN have signed a strategic MoU. They will integrate Pharos's institutional blockchain with KUN's licensed global payment rails to drive the tokenization of supply chain credit assets and enable more efficient global settlement on-chain. **Background:** Emerging market SMEs face severe working capital challenges due to slow, costly traditional trade finance, often waiting 30-90 days for payment after delivery. While RWA tokenization is a focus, few projects effectively connect underlying infrastructure to real commerce and licensed payment networks. **Collaboration Focus:** The partnership aims to bridge this gap by bringing supply chain credit and B2B cross-border payments on-chain compliantly. Initial priorities include: * Tokenizing supply chain credit assets to unlock liquidity. * Enabling native on-chain settlement of digital assets. * Exploring enterprise virtual card solutions. * Providing compliant on-chain financial services for verticals like commodities, trade, B2B e-commerce, and Web3. **Executive Quotes:** * Wish Wu, Co-founder & CEO of Pharos Network, highlighted KUN's trusted, licensed payment network as a perfect fit for bringing supply chain assets and cross-border capital flows on-chain accessibly. * Dr. Louis Liu, Founder & CEO of KUN, stated that settlement certainty is RealFi's final hurdle. Bridging KUN's payment rails with Pharos's infrastructure will help convert on-chain assets into real-world liquidity with institutional-grade trust. They will also explore AI-driven optimization for global capital flows. Pharos mainnet is live with over 50 dApps. This partnership strengthens its position as RealFi infrastructure by linking licensed payment systems with on-chain finance.

Deconstructing Anthropic: The Best AI Company May Also Be an Organizational Invention

Anthropic has emerged as one of the most notable AI companies, distinguished by its strategic focus and unique organizational culture. Strategically, Anthropic demonstrated exceptional foresight by prioritizing coding early on, recognizing it as a critical path for model learning, commercial value, and accelerating AGI research. Unlike OpenAI's expansive, multi-front approach, Anthropic maintained rigorous focus on scaling language models and the coding vertical, avoiding distractions like multimodal development. This discipline stemmed partly from resource constraints but also from the conviction of its leadership, particularly co-founder Dario Amodei, who exhibits a strong, independent strategic vision. Organizationally, Anthropic’s culture is its “secret sauce.” It is characterized by a strong, mission-oriented focus on AI safety, high trust, low ego among employees, and a distinct humanistic ethos. This culture has resulted in remarkably low talent attrition and high retention rates. Key practices sustaining this culture include stringent cultural screening in hiring, high-context transparency and writing practices led by leadership, a founding structure of seven co-founders with equal equity to diffuse values, and a deliberate “one team” approach that minimizes internal silos and hierarchy. This culture is both a reaction to the political dynamics its founders experienced at previous companies and a functional necessity for the data-intensive, collaborative “dirty work” required to excel in coding and agentic AI. While OpenAI remains a formidable competitor with greater resources and exploration, Anthropic’s success illustrates how focus, cultural cohesion, and a steadfast mission can be powerful drivers in the AI race.
