Sorella Labs 开发 Brontes 和 Angstrom 工具来缓解应用层面的 MEV。

撰文:0xNatalie

Sorella Labs 昨日宣布完成 750 万美元种子轮融资,该轮融资由 Paradigm 领投,其他参与者包括 Uniswap Ventures、Bankless Ventures、Robot Ventures 和 Nascent。Sorella Labs 是一家致力于解决以太坊生态系统中 MEV 问题的加密初创公司。

核心工具概览

Sorella Labs 正在开发两款核心工具:

Brontes:一款开源的区块链分析工具,能够处理以太坊区块数据,分类交易行为,并通过模式匹配和分析识别 MEV。可以被视为一个具有自定义区块分析功能的开源 Etherscan。Brontes 已于今日上线并开放使用。

具体来说,Brontes 能够根据交易的具体行为进行分类,包括交易的发起者、接收者、交易金额、Gas 费用等。并将原始的以太坊区块链数据转化为结构化、易于分析的格式,极大简化了数据预处理过程。此外,Brontes 还结合了链外数据(如中心化交易所价格、元数据、点对点数据等),使得分析更加全面和准确。为了满足不同用户的需求,Brontes 提供了一个模块化框架,用户可以根据自己的需求创建和应用不同的分析方法。这使得 Brontes 成为一个开放性极高的工具,适合用于复杂的区块链数据分析。

Angstrom:一款旨在减少去中心化交易所中常见套利行为的工具,计划作为 Uniswap V4 的一个 hook 推出。Uniswap V4 引入了一些新功能包括 hook、单例设计(所有的流动池都由一个合约管理)和支持原生 ETH 交易对等,预计将在今年下半年上线。V4 中,hook 是一种与流动性池绑定的可定制智能合约,允许开发者在流动性池生命周期中的特定点执行自定义代码,从而实现复杂的逻辑和功能。Angstrom 作为 hook 将通过 Sorella 的链下网络,在每个区块内运行两次拍卖机制。

  • 第一次拍卖:目的是决定哪个交易可以在区块内最先被处理。交易顺序通常是由交易的 Gas 费用和提交时间决定的,容易被抢跑交易者(front-runners)利用,他们通过支付更高的 Gas 费用来确保在大额交易之前执行交易,从而利用大额交易导致的价格变化来获利。而 Angstrom 的第一次拍卖是公平竞价的,即使抢跑交易者尝试插入他们的交易,也需要通过拍卖机制来争夺优先权。这样一来,攻击者无法再仅仅通过提高 Gas 费用或快速提交交易来确保自己的交易在大额交易之前被处理。

  • 第二次拍卖:是一个批量拍卖,所有订单会在同一个价格点执行,避免因单笔大额交易导致的价格剧烈波动,从而防止三明治攻击和一般套利行为,进一步增强了防护。

Sorella Labs VS Flashbots

Flashbots 和 Sorella Labs 目标相似,但在具体实现方式和目标用户上有所不同,形成了互补的关系。

Flashbots 专注于解决以太坊协议层面的 MEV 问题,旨在通过优化矿工和验证者的操作流程,实现更公平和透明的 MEV 提取。Flashbots 推出了 MEV-Boost 等一系列工具,通过建立一个标准化的 MEV 拍卖系统,减少网络中的恶意竞争行为,确保矿工和验证者能够在公平的环境中提取 MEV。这些工具不仅减少了验证者之间的不公平竞争,还缓解了 MEV 的负面影响。Flashbots 的核心目标是提升以太坊网络的整体安全性和透明度,同时为参与者创造一个更公平的竞争环境。

Sorella Labs 则聚焦于应用层面的 MEV 缓解,开发 Brontes 和 Angstrom 等工具,直接作用于 DeFi 应用程序层,旨在减少流动性提供者的损失并提高用户的交易执行质量。Sorella Labs 的核心目标是通过改善应用层的交易公平性和效率,保护 DeFi 用户的利益。

Opinion: AI Bubble Bursts, Bitcoin and Other Risky Assets Are the First to Be Impacted

BIS Warns AI Investment Boom Could Trigger Market Stress, Impacting Bitcoin First The Bank for International Settlements (BIS) warns that a potential bursting of the "AI bubble" could tighten liquidity and severely impact risk assets like Bitcoin in the near term. Major tech firms are projected to spend over $1 trillion on AI infrastructure in 2025-2026. The BIS cautions that if returns fail to meet expectations, a sudden withdrawal of financing could turn this investment boom into a prolonged bust, creating ripple effects across financial markets. While AI holds long-term economic promise, the current scale and speed of investment, coupled with intense competition and physical bottlenecks (e.g., semiconductors, power grids), mirror historical bubbles. The report highlights that the AI funding web—spanning corporate debt, private credit, and complex vendor agreements—makes systemic risks harder to see. A disappointment in AI adoption could transmit stress through this chain, widening credit spreads and pressuring weaker borrowers. For Bitcoin, the initial reaction to such a market shock would likely be defensive. As liquidity tightens, investors typically sell liquid assets first, and Bitcoin often trades in line with other risk assets during portfolio de-risking. Recent correlations, like Bitcoin's drop following a sharp decline in South Korea's stock market, support this view. However, the longer-term outcome for Bitcoin depends on the policy response. If an AI-driven credit crunch forces central banks to inject liquidity and ease policy eventually, it could reignite Bitcoin's narrative as a hedge against monetary debasement. Yet, traders betting on this outcome may first have to endure significant market volatility and potential price declines.

South Korea Reaps Riches, America Turns Hostile

The US has filed a collective antitrust lawsuit in California against Samsung, SK Hynix, and US-based Micron, alleging they colluded to create a "RAMpocalypse" by slashing traditional DRAM production and raising prices 700% over four years amid the AI boom. This lawsuit targets the heart of the AI supply chain: High Bandwidth Memory (HBM), critical for Nvidia's GPUs. Currently, SK Hynix (57%), Samsung (22%), and Micron (21%) dominate global HBM production. The case highlights a deeper US concern: in the AI era, South Korea, through its HBM dominance, is capturing an estimated 35% of global AI profits, second only to the US (49%). SK Hynix's operating profit margin recently hit a record 72%. In response to the lawsuit, South Korea announced a massive $800 trillion won investment to build four new chip plants, doubling down on its strategic position. Analysts see the lawsuit not merely as a consumer price issue but as strategic pressure. It aims to support Micron's US manufacturing expansion (subsidized by the CHIPS Act) and secure America's share of AI profits by bringing more HBM production onshore. However, South Korea's rapid execution and massive cash flow from current HBM sales give it a significant speed advantage over US build-out timelines. The conflict underscores a fundamental shift: AI infrastructure like GPUs and HBM is becoming a new form of strategic national resource, akin to oil. While Nvidia and Korean memory giants are interdependent, the struggle over profit distribution and industrial sovereignty in this new landscape is just beginning. This lawsuit may be the first major skirmish in the AI resource wars.
