5 月 5 日,总奖池 10 万美元的 ETHGlobal Sydney 黑客松,公布入围决赛的 8 个项目,分别是:Relief Link、HoverChain、Retake//Regen、Cache Coherence、0x Poll、Roman Kyoto、Zeke 和 AlibudaHabitBuilder。本文带你一览 8 个项目的相关信息:

Relief Link

Relief Link 是一项创新服务,旨在在灾害发生后立即自动分发援助,利用区块链技术进行高效安全的运营。该项目集成了 Chainlink 预言机,用于实时灾难监控和自动交易,确保及时向特定范围内的受影响者提供援助。该系统通过 Unlimit 和第三方网络的帐户抽象来吸引用户,甚至是那些刚接触加密货币的用户,从而方便地使用法定货币选项。

Relief Link 使用 Worldcoin 进行身份验证,以保持系统完整性并防止欺诈,确保每个经过验证的用户分发一次援助。Relief Link 平台利用 PredictHQ 的 API 来跟踪和分析用户注册位置 100 公里范围内的各种自然灾害(如洪水、火灾和地震)的影响。这些数据在网站上进行可视化展示,提供了对亚太地区最近灾害趋势的见解。

HoverChain

HoverChain 是一个 Google Chrome 扩展工具,可滚动访问区块链数据。只需选择区块链标识符(如以太坊地址或合约),就会显示一个详细的弹出窗口,其中包含重要统计数据,如钱包余额、最近的交易和可用的智能合约交互。HoverChain 利用 Alchemy API 和 Mantle Block Explorer API 来访问最新的区块链数据。

Restake//Regen

Eigenlayer AVS 公共产品,允许以太坊验证者通过承诺购买和退还高质量碳信用额度来抵消网络碳排放的一小部分。

验证者在 Restake//Regen AVS 注册(选择加入),并自行选择以太坊总网络的%承诺(0.0001% 到 1% 之间),然后每个 epoch(28 天)必须将所需数量的 CHAR 发送到 Restake//Regen 资金池合约,然后定期撤回。每笔捐款的收据都存储在资金池中。

Cache Coherence

Cache Coherence 使用 CCIP 和 World Coin 扩展账户抽象智能钱包,以恢复丢失的密钥。Cache Coherence 是 EIP-4337 账户抽象智能合约钱包的扩展,可以部署在任何 EVM 链上。钱包包括设置 WorldCoin ID。WorldCoin ID 提供了一个二次身份验证,可以在密钥丢失的情况下用作恢复方法。

然而,支持 WorldCoin 登录验证方法的区块链数量有限。因此,CCIP 是账户钱包和 WorldCoin 验证器之间的桥梁。 CCIP 是双向的,允许将证明从账户发送到 WorldCoin。验证成功或失败后,响应将通过 CCIP 发送回帐户。

0x Poll

政治投票平台0x Poll 旨在创建一个应用程序,允许用户将其 WorldID 与选民名册详细信息相关联,然后与反映澳大利亚联邦议会立法的投票平台交互,无需泄露任何个人信息。0x Poll 允许用户对个别立法进行投票,投票结果将在选民层面收集,以便有效地游说现任议员。

Roman Kyoto

Stablecoin Salaries: Why Are They Becoming the First Choice for Cross-Border Workers?

Stablecoin Salaries: Why They're Becoming the Top Choice for Global Remote Workers The traditional global salary system carries hidden exchange rate risks for freelancers in countries like India, Argentina, and Turkey who earn in USD but spend in local currencies. When salaries are instantly converted to local currency, workers lose purchasing power if that currency depreciates against the dollar. For instance, an Indian designer converting a $2000 monthly salary to rupees lost over 10% in purchasing power last year due to the rupee's decline. Holding even a portion of income in USD or USD-pegged stablecoins can preserve value. Stablecoins offer a solution by breaking down barriers to holding dollars. Opening foreign USD bank accounts is difficult, and international wire transfers incur high fees (averaging 6.5%) and delays. In contrast, stablecoin transfers are fast and low-cost. Furthermore, many countries with high inflation and depreciating currencies restrict citizens' access to foreign currency. Self-custody stablecoin wallets enable workers to hold dollar-equivalent assets without needing bank approval, bypassing these limits. These wallets integrate multiple functions: they allow users to convert only what's needed for daily expenses into local currency, keep the remainder in stablecoins, connect to on-chain lending or yield products, and even link to payment cards for direct spending. While challenges remain—such as the lack of deposit insurance and evolving regulatory frameworks—the trend is clear. Reports indicate a growing preference for USD or stablecoin payments among freelancers in high-inflation countries. This shift represents a fundamental restructuring of salary functions: payment currency, asset storage, yield generation, spending, and cross-border flow. It offers the freedom and flexibility that are core to money's purpose, signaling a profound change in the global financial landscape.

Don't Just Focus on Layoffs, The New Structure of the Ethereum Foundation is More Worthy of Appreciation

The Ethereum Foundation (EF) has undergone a significant organizational restructuring, with the most notable change being a strategic refocusing of its priorities rather than just a 20% staff reduction (approximately 54 people). The new structure clearly prioritizes the Protocol and Access layers, which now comprise the largest teams (57 and 34 people, respectively). This signals EF's intent to concentrate its core resources on fundamental, hard-to-outsource aspects of Ethereum: protocol evolution, security, privacy, client development, and the foundational access layer. Key areas within the Protocol layer, led by an architecture group including Vitalik Buterin and Justin Drake, receive heightened emphasis. These include post-quantum security, zkEVM, formal verification, and long-term roadmap development ("Strawmap"). This reflects a shift towards tackling complex, interdependent challenges like scalability, privacy, and future-proofing the protocol, potentially moving from a pure "redundant security" multi-client model towards more specialized clients aided by AI-assisted formal verification. Financially, EF's budget is being reduced by approximately 40%. The goal is to transition from spending about 15% of its remaining funds annually to a more sustainable 5% rate, akin to a long-term endowment, ensuring its longevity. Concurrently, the restructuring involves pushing certain responsibilities—such as application development, adoption, and ecosystem coordination—to external organizations like EthLabs, the Ethereum Apps Guild, and others. This "multi-node" model aims to increase ecosystem resilience by decentralizing functions beyond the EF, though it introduces new coordination challenges. In essence, the reorganization represents EF consciously narrowing its scope to focus on the hardest, most critical protocol-level problems while fostering a more distributed and sustainable ecosystem structure for Ethereum's future growth.

Report Analysis: What Is Coherent Planning as CPO Booms?

Title: Report Interpretation: What Moves Is Coherent Making Amid the CPO Boom? Summary: JP Morgan analyst Samik Chatterjee reiterates an Overweight rating on Coherent (COHR), citing undervalued growth potential across three core areas: data center optical transceivers, co-packaged optics (CPO) chips, and industrial lasers/thermal management. COHR's 1.6T data center transceivers are in high demand, with pricing remaining firm. The rise of CPO is seen not as a threat but as a catalyst, creating higher demand for sophisticated optical components, an area where COHR holds a competitive edge with its comprehensive portfolio (lasers, isolators, VCSELs, thermoelectric coolers). Each CPO chip offers significantly greater revenue potential than traditional transceivers. Furthermore, its Optical Circuit Switch (OCS) technology targets a potential $4B market with reliability and power advantages. The company is expanding its InP (Indium Phosphide) device capacity fourfold within two years, securing substrate supply and transitioning to more cost-effective 6-inch wafers. As one of only two major suppliers of high-quality pump lasers—currently in severe shortage—COHR can now move up the value chain from components to complete line cards/systems, boosting ASP over tenfold. Gross margin targets (>42%) may be revised upward due to high-end product premiums, cost improvements from the wafer transition, and contributions from new high-margin products like CPO and OCS. Its efficient thermadite thermal material also offers long-term growth. Industrial segment revenue grows at a steady 5-10%, supported by semiconductor equipment orders. Changes in Apple's Face ID protocol present a re-competition opportunity for 3D sensing. Overall, Coherent is positioned as a key infrastructure provider, with AI-driven compute demand fueling the need for high-speed optical interconnectivity. Growth from CPO/OCS, stable industrial performance, and margin improvement support the bullish thesis. *Disclaimer: This summary interprets a third-party analyst report from JP Morgan.

After Laying Off 20% of Staff, What Are the Key Points of EF's New Structure?

Following the completion of a months-long organizational restructuring, the Ethereum Foundation (EF) announced a 20% workforce reduction (approximately 54 employees) on June 23rd. It reorganized its teams into five new core clusters: Protocol, Access, User, Community, and Institutional (plus Operations/Management support units). Officially, this move implements the EF's 2026 Mandate and 2025 Treasury Management Policy, aiming to create a more focused and "self-sovereign" organization. The restructuring prioritizes the CROPS principles—Censorship Resistance, Openness & Freedom, Privacy, and Security—as foundational organizational tenets. The Protocol cluster will focus on core protocol R&D, including MEV reduction and zkEVM. The Access cluster emphasizes preserving user "zero option" for non-custodial, permissionless interaction. The User, Community, and Institutional clusters will manage external engagement, with the latter handling institutional and regulatory matters. While offering enhanced severance and transition support for affected employees, the EF did not disclose budget allocations or specific KPIs for the new clusters. This has led to market uncertainty about the impact on project funding and development priorities. Analysts note the announcement's positive tone of mission focus contrasts with a backdrop of recent EF leadership changes and broader ecosystem pressures. The true impact—whether this signifies strategic realignment or reactive contraction—will become clearer as the new structure's resource allocation and project prioritization are revealed in the coming months.
