ETHGlobal 布宜诺斯艾利斯黑客松活动于 11 月 23 日落下帷幕。本次黑客松汇聚了以太坊生态系统中的顶尖人才和专家,吸引了诸多开发者团队探索区块链技术的新应用场景。此次活动的奖金达 50 万美元。

经过评审,在参赛的 475 个项目中,十个项目脱颖而出,涵盖 NFT、DeFi、预测市场等领域。PANews 带你速览这 10 个项目。

Paybot

Paybot 展示了基于区块链微支付的 X402 Payment Required 协议,用于控制物理设备的访问权限。该系统专为 Coinbase 开发者平台黑客松而开发,展示了无需 Gas 费用的交易,用户可以使用 QUSD 稳定币支付租赁机器人的费用,而无需持有 ETH 支付 Gas 费用。

该系统实现了一个完整的支付服务架构:用户在其钱包中签署 QUSD 支付授权,服务商将交易提交到链上并支付 Gas 费用。该项目让物联网和机器人应用能够真正实现微支付,否则高 Gas 费将令人难以承受。

该项目由 @sprpstsn 构建。

JetLagged

JetLagged 是一个基于 Celo 和 Oasis 构建的去中心化预测市场平台,用户可以在这里预测航班延误和取消。该平台使用 Next.js、Bun.js 和 Solidity 构建,并部署在 Celo 区块链上。

Payload Exchange

Payload Exchange 允许商家使用 x402 代理接受任何形式的支付,发送方可以选择代币,接收方则可以无缝地获得稳定的资产。

Payload Exchange 是一个代理层,它拦截 x402 支付请求并引入第三方:赞助商。这扩展了终端用户的支付体验,除了稳定币或其他货币之外,用户还可以选择其他支付方式。赞助商会支付部分或全部款项,以换取用户的操作或数据。

三方合作模式惠及所有参与方:

  • 赞助商:通过支付内容访问费用来获取用户、收集数据或引导特定行为。

  • 内容提供商:降低访问门槛。无需设置付费墙即可实现内容变现。

  • 用户:通过交易操作 / 数据而不是金钱,即可免费或以折扣价获取高级内容 / 工具。

该项目由 qap、luis、Marcelo、Soko 构建。

Yoga

Yoga 项目实现了一个非同质化 (NF) 仓位管理器,允许 LP 在单个 NFT 中管理复杂的多区间仓位。与每个 NFT 仅代表一个价格区间的传统仓位管理器不同,Yoga 可以在单个 ERC721 代币下管理多个子仓位(不同的价格区间),从而实现跨价格区间的复杂流动性分配策略。

该合约提供了一个简单的应用程序二进制接口 (ABI),允许 LP 简单地指定他们想要应用的修改(流动性增量),合约会自动计算如何修改底层 UniV4 仓位。

该项目由 Charlie Mack、Duncan Townsend、Luigi、Michael Fautch 构建。

LensMint Web3 Camera

LensMint Web3 Camera 是一款基于硬件的系统,可在拍摄照片时进行签名,并生成经零知识证明的链上 NFT,从而实现防篡改、认证的记忆。

LensMint 提供了一种无需信任的方式来证明照片的设备来源、时间戳和完整性,从而为创作者、记者、活动组织者和科学文献解决真实性、来源和货币化问题。

该项目由 Mohit Bhat 构建。

Halo

Halo 是一款基于 World Chain 的小程序,它将真实购物小票转化为链上奖励,奖励给已验证的用户。用户扫描任何商店的购物小票,Halo 会通过轻量级的处理流程对其进行评估,然后将奖励发放给已通过 World ID 验证的用户。整个流程中,用户的个人身份始终保持私密。

购物小票包含着关于真实经济行为的重要信息,但这些信息通常会丢失或被锁定在封闭的系统中。Halo 捕获这些信息,每张小票都会经过处理,提取出商家、时间戳、总额、货币和类别等详细信息。奖励只能由特定的用户领取,从而创建了一种防女巫攻击、保护隐私的方式,将线下行为与链上奖励联系起来。

该项目由 hellocrypto、@DNC_Labs 构建。

zkx402 (ProofofLeak)

zkx402 是 x402 协议的扩展,它集成了零知识证明,用于验证可变支付和可验证内容。

消费者(人类或人工智能代理)有不同的定价等级,能够使用零知识凭证验证身份的用户可获得折扣。生产者可以通过附加零知识证明来证明其内容的来源。例如,特定记者确认的作者身份、人工创作证明、带有 GPS / 传感器详细信息的物联网数据。

举报人无需透露身份即可获得报酬。记者可以通过证明自己是人类或就职于信誉良好的媒体机构来获得更低的访问成本。记者控制的 AI 代理通过 Base 上的 x402 自主支付以访问私人敏感数据。

该项目由 Guilherme、Lam、Ra's Al Ghul、Mark Ballew、vaughn 构建。

Aqua0

Aqua0 是一款利用 Aqua AMM 和 LayerZero 消息传递实现无缝资产转移的跨链共享流动性小程序。

Aqua 是由 1inch 开发的共享流动性层,旨在解决当前 AMM 中存在的效率低下问题。这些问题包括:1) 90% 的 AMM 流动性从未被使用,导致流动性停滞。2) 这造成流动性分散,因为 AMM 最终会在不同协议和链的不同 LP 处拥有闲置和未利用的流动性。

Aqua0 以跨链的方式改进了 Aqua。Aqua 目前的问题是它作为一个记账层,一次只能在一条链上使用。Aqua0 将创建一个跨链 AMM 市场,利用 Layer Zero 的跨链组件和 Aqua 的共享流动性合约,使 LP 能够解锁新的收益机会,从而提高资本效率。

该项目由 Yudhishthra Sugumaran、Andrei De Stefani、@tomasmazzi 构建。

BMCP

BMCP(比特币多链协议)通过真正的跨链可编程性连接比特币和 EVM 链。用户可以使用原生 Schnorr 签名(Taproot/BIP340)签署比特币交易来触发 EVM 交易(DeFi 兑换、代币转移、合约调用)。

跨链中继引擎 (CRE) 扫描比特币区块,并在检测到嵌入在 OP_RETURN 中的有效、经 Schnorr 认证的 BMCP 消息时,在 Polygon、以太坊等链上执行链下(风险管理、验证)和链上(合约调用)的安全调用,无缝利用 Chainlink CCIP。 BMCP 确保所有流程保持信任最小化,通过加密技术锚定到比特币的最终性,并可在不同的生态系统中组合使用。

该项目由 Vibhav Sharma、Vollantre、James Scaur、Manuel 构建。

EternaFi Agents and $AINFT: A Comprehensive Analysis of AI-Powered NFT Infrastructure in the Web3 Ecosystem The intersection of artificial intelligence (AI) and blockchain technology is rapidly evolving, establishing innovative platforms that redefine ownership models and economic participation. EternaFi Agents, along with its native token $AINFT, exemplifies a groundbreaking approach to the tokenization of AI infrastructures through the means of non-fungible tokens (NFTs). Launched in July 2025 by the development team at Nova Club, EternaFi merges the advancements of AI with the decentralized financial mechanisms of blockchain, presenting a unique investment opportunity for participants within the web3 ecosystem. This article aims to provide an in-depth assessment of EternaFi Agents, covering its core components, functionality, and significance within the crypto landscape. Introduction and Project Overview EternaFi Agents stands as a salient example of how blockchain technology can democratize access to advanced AI capabilities. The project endeavors to reshape the paradigm of AI ownership by diversifying economic participation, making sophisticated AI systems accessible to a larger pool of stakeholders. At its core, the project tokenizes a proprietary large language model (LLM) developed by Nova Club, allowing NFT holders to gain fractional exposure to the model's economic performance. By utilizing NFTs representing stakes in the LLM, EternaFi Agents fosters a model wherein stakeholders not only participate in AI service consumption but also enjoy sharing in the economic rewards generated by the platform. This transformative approach enables the development of sustainable revenue models for AI services, all the while promoting broad community engagement and facilitating transparent governance. What is EternaFi Agents? EternaFi Agents represents an AI-NFT infrastructure project that aims to blend the capabilities of AI with blockchain technology in a coherent ecosystem. The essential feature of this project is the creation of NFTs that serve as financial instruments, representing fractions of ownership in Nova Club's proprietary AI infrastructure. Each NFT symbolizes direct exposure to the economic performance of the underlying AI system, providing a lucrative opportunity for investors. The project operates on the Base blockchain, known for its scalability and efficiency, thus ensuring manageable transaction costs while facilitating a seamless operational experience. One of the notable features includes a revenue-sharing mechanism, wherein NFT holders can receive portions of subscription income generated by the AI services provided on the platform. This innovative approach establishes a connection between the success of the AI services and the economic dividends distributed among the holders, thus ensuring an alignment of interests across the community. Who is the Creator of EternaFi Agents? The creative force behind EternaFi Agents is Nova Club, a development team based in Singapore proficient in the amalgamation of AI and blockchain technology. Their prior experience in AI development and cryptocurrency analysis gives credence to the project, contributing a breadth of expertise to the creation of EternaFi Agents. Nova Club’s mission centers on democratizing access to cutting-edge AI technologies while building sustainable economic models that benefit users alongside developers.

Who are the Investors of EternaFi Agents? The specific details concerning investors or investment organizations backing EternaFi Agents are not publicly available. However, EternaFi has adopted an inclusive approach to funding its development through the sale of NFTs to the public, allowing a wide array of participants to invest in the ecosystem. The project’s architecture ensures that core infrastructure is funded responsibly while allowing community members to partake in the ownership and economic returns generated from the AI services. This model emphasizes community engagement by aligning the interests of investors and project developers, creating a collaborative environment where long-term participation is incentivized. How Does EternaFi Agents Work? EternaFi Agents operates through a multifaceted ecosystem where NFTs serve as a primary means of ownership representation within the project. Each NFT holder is entitled to a share of the monthly subscription income produced by the underlying AI-powered platform, thereby positioning NFT ownership as a lucrative investment vehicle. Revenue Generation Mechanism The primary source of revenue generation for the EternaFi platform stems from subscription fees related to the AI services provided. Users can access various tiered services, ranging from basic market analysis tools to comprehensive AI-assisted trading solutions. These services are monetized and form the basis for the revenue-sharing framework, which distributes profits to NFT holders through automated smart contracts. An innovative feature of the EternaFi ecosystem is the revenue-sharing mechanism that operates transparently, ensuring that rewards are allocated based on verifiable metrics from the AI platform's operations. This creates a direct link between the performance of AI services and the returns available to community investors, establishing a sustainable economic model. Staking and Vesting Mechanisms Participants within EternaFi can engage in staking their NFTs to unlock additional economic benefits. The vesting schedule is designed to promote long-term commitment among participants, rewarding those who exhibit ongoing support for the project. This ensures a robust alignment of interests and fosters a sense of community engagement essential for achieving the project's long-term goals. Transparent Governance EternaFi Agents embraces decentralized governance, allowing NFT holders to play an active role in decision-making regarding the platform's development and future directions. The governing structure includes community voting mechanisms, providing NFT holders with the opportunity to influence significant decisions and contributing to a collaborative approach to project growth. Timeline of EternaFi Agents The development trajectory of EternaFi Agents showcases a systematic approach toward building a sustainable AI infrastructure while meeting the needs of community participants.

Operating on the Base blockchain, the project leverages the advantages of scalability and low transaction costs. The underlying smart contract architecture governs the NFT ownership, revenue sharing, and community management features, ensuring efficiency and transparency. AI System Development The proprietary large language model underpinning EternaFi Agents has been independently developed and designed to cater to revenue-generating applications without reliance on proprietary external frameworks. This endeavor reflects a commitment to creating a versatile and adaptable AI infrastructure capable of delivering meaningful services to users, thus generating economic value for investors. Security Measures The robustness of EternaFi’s security infrastructure is paramount. Regular audits and stringent security measures ensure the integrity of the AI systems and blockchain mechanisms, safeguarding against potential vulnerabilities while fostering confidence among participants. Conclusion EternaFi Agents signifies a landmark innovation within the realm of artificial intelligence and blockchain technology, opening avenues for community ownership and economic participation in advanced AI capabilities. The project’s comprehensive strategy to tokenize AI infrastructure via NFTs establishes a precedent for future decentralized ecosystems. By harmonizing technical sophistication with user-centric economic models, EternaFi not only fosters engagement but also generates a sustainable revenue-sharing framework for community participants. The significance of EternaFi extends well beyond its operational success as it exemplifies how blockchain can democratize cutting-edge AI technologies, paving the way for future ventures in this intersectional space. The evolution of EternaFi Agents may herald a new era of AI development characterized by participant-driven governance, sustainable economic models, and transparent verification, ultimately contributing to the broader democratization of AI and technology accessibility across industries.
