Orbiter Finance 与以太坊基金会及加州大学圣巴巴拉分校合作加强桥接协议的安全模型

链捕手Published on 2024-11-25Last updated on 2024-11-25

Orbiter Finance 正在积极推进其在以太坊生态系统中的整合。最近，该公司与以太坊基金会的 Kyle Charbonnet、加州大学圣巴巴拉分校的教授，以及 Nubit 的创始人 Feng Yu（@captain8299）联合发布了一项关于跨链桥安全性的研究，题为《Scutum: Temporal Verification for Cross-Rollup Bridges via Goal-Driven Reduction》。这篇论文由以太坊生态安全领域的专家和学术教授共同撰写，提出了一种数学模型，并对 Orbiter 桥在过去 2-3 年的链上数据进行了回测，旨在通过建模的方式提前识别欺诈交易。这一合作旨在为 Orbiter 的 Maker 系统提供理论支持和实践指导。

研究论文的核心内容

该论文深入探讨了如何通过可扩展验证器系统来评估跨 Rollup 桥接的安全性。研究团队强调了三个关键点：

  1. 可扩展验证器：Scutum 对主流跨 Rollup 桥（包括 Orbiter Finance）的评估发现了多个零日漏洞（zero-day vulnerabilities）。该方法利用一个全面的多模型框架，捕捉个体行为与各组件之间复杂交互的时间属性。同时，为了增强可扩展性，论文引入了通过合同图表示法进行可达性分析。
  2. 安全模型构建：Scutum 通过合同图的可达性分析来近似时间安全验证，结合程序分析技术。此外，它还采用冲突驱动的细化循环，以消除假阳性，从而提高模型在不同桥接模型中的预测准确性。
  3. 性能表现：Scutum 工具展示了良好的运行时性能，使得高效的分析适用于实时或近实时的应用场景。

对安全性的承诺

自 2021 年成立以来，Orbiter 一直在安全性方面进行深入探索，致力于成为跨链领域可靠的基础设施。Orbiter Finance 的核心产品 Vizing 技术负责人 Juson Xia 表示：“我们永远不会放弃构建更安全的跨链桥模型。除了通过回测链上数据主动识别潜在的欺诈交易外，我们还将深化与以太坊和加密学家的学术沟通与工程合作。”

Solana under pressure: Pump.fun’s $10M SOL move sparks THIS Q3 debate

The article discusses the impact of memecoin launchpad Pump.fun's recent sale of $10.08 million worth of SOL on the Solana ecosystem and its price outlook. While Pump.fun's high trading volume and revenue growth demonstrate strong on-chain activity and demand for Solana's network, its large-scale SOL sales have sparked a debate about value extraction from the ecosystem. This selling pressure, coupled with a broader risk-off sentiment, is testing Solana's fundamentals. Despite robust network metrics, SOL struggles to break key resistance levels like $100 and $80. The central Q3 debate is whether Solana's underlying network growth and application activity can generate enough demand to overcome this selling pressure and support a price recovery, or if the weakness will persist.

Swift readies blockchain ledger for live tokenized payment pilots with 17 global banks

Swift has transitioned its blockchain-based ledger from development to live implementation, announcing pilots with 17 global banks across six continents for cross-border payments using tokenized deposits. This marks Swift's first live use case for the ledger, enabling 24/7 payments while settling through existing financial infrastructure. The initiative signals institutional adoption of regulated digital asset technology over public blockchains. The shared ledger acts as an orchestration layer, allowing banks to move tokenized deposits from their own ledgers, improving liquidity and flexibility without altering compliance frameworks. Initial pilot banks include major institutions like Citi, HSBC, and UBS. Unlike stablecoin-based systems, Swift's platform uses bank-issued tokenized deposits, keeping transactions within the regulated banking system to enhance efficiency and transparency while maintaining existing settlement rails.

Decoding EigenCloud’s market defying rebound – 2 factors fueling EIGEN

EigenCloud's EIGEN token has staged a significant rebound amid broader market turmoil, driven by two key bullish factors. First, on-chain capital flows have strengthened, with Total Value Locked (TVL) rising by over $353 million to approximately $4.719 billion, indicating growing investor conviction. Second, derivatives market activity turned bullish, marked by a 27% surge in Open Interest (reaching ~$43 million) and a positive Funding Rate, signaling strong long positioning, though increased retail participation introduces volatility risk. Furthermore, the protocol's fundamentals improved as quarterly losses narrowed substantially, from $8.70 million in Q1 2026 to about $2.43 million. The combination of rising on-chain liquidity, bullish trader sentiment, and better financial performance suggests the rally may have room to extend.

Pantera Capital: As Perpetual Swaps Move to the Financial Center, Hyperliquid is Attempting to Contain Everything

"Perpetual futures are evolving from a crypto-native innovation to a fundamental shift in market structure, increasingly adopted by traditional investors. Offering advantages like no expiry dates, simplified risk management, and 24/7 trading, they are becoming the dominant tool for leveraged directional exposure. While pioneered in crypto by BitMEX, decentralized exchanges (DEXs) like Hyperliquid are now driving significant growth. Hyperliquid, the largest DEX for perps, has captured ~40% of on-chain volume by building a custom L1 blockchain for high performance and enabling permissionless listing of assets through HIP-3. Its vision to 'accommodate all finance' has led to expansion into equities, commodities, and indices. During market closures or events (e.g., weekends, geopolitical tensions), Hyperliquid serves as a price discovery venue, attracting attention from traditional funds and exchanges like ICE, which now views it as a competitor. While regulatory uncertainty in the U.S. remains a key risk, recent CFTC actions approving certain crypto perpetual contracts signal a potential shift. The core question is whether blockchain-based infrastructure like Hyperliquid can become the primary venue for pricing and trading risk across all finance."

Zapper shuts down after 7 years despite $13B peak volume – Details

Zapper, a DeFi asset manager, is shutting down after nearly seven years of operation. Despite attracting over 2 million active monthly users and processing over $13 billion in peak transaction volume, the company failed to build a sustainable business model. Intense competition led to declining revenue and narrowed profit margins, while infrastructure costs remained high. The platform will cease operations on August 3. CEO Seb Audet acknowledged Zapper fell short of its mission to make DeFi more accessible. The shutdown underscores a key challenge in the sector: monetizing infrastructure beyond user growth. Zapper had secured $15 million in venture funding but was unable to achieve profitability, highlighting a shift where investors now prioritize sustainable revenue over growth alone. The case suggests successful DeFi projects require strong monetization, disciplined spending, and clear competitive advantages for long-term survival.
