DualPool 的出现，让我越来越确定一件事：V4 Hooks 真的开始了 很多人看到的是 Spark 把 1.5 亿美元稳定币流动性迁到了 Uniswap v4 我看到的是另一件更重要的事： Hook 已经开始从"概念"进入"生产环境” 以前大家聊 Hook，更多是在讨论： Hook 能做什么？ 能不能实现？ 有没有人会用？ 现在这些问题，正在变成： 已经完成审计 已经开源 已经有真实协议部署 已经有真实资金验证 这是质的变化 很多人还不知道 DualPool 到底解决了什么 传统 LP 很简单： 资金一直放在池子里，等待别人来交易 除了赚手续费，大部分时间资产都是闲置的 DualPool 不一样 LP 的资金平时放在 ERC-4626 Vault 里赚收益 有人交易时，Hook 再把资金瞬间调到 Pool 完成 Swap，交易结束后立即回到 Vault 同一份资金，同时赚： Swap Fee Vault Yield 这就是 Hook 带来的资本效率提升 更重要的是，它改变的不只是收益 它改变了 Uniswap 的定位 以前，AMM 更像一个交易池 现在，Hook 让它变成一个可编程的流动性执行层 开发者可以把自己的金融逻辑直接写进交易生命周期 例如： 交易前，可以做权限控制、动态费率、风控 交易中，可以做 JIT 流动性、MEV 防护、库存管理 交易后，可以做奖励分配、收益结算、NFT 更新、链上状态同步 交易本身，开始变成一个可以编程的过程 这也是为什么： V4 Hooks 不是一个新功能，而是一套新的金融开发框架 未来真正竞争的，不是谁 Fork 一个 AMM 而是谁能写出更好的 Hook 谁能提高资本效率 谁能降低做市成本 谁能吸引真实流动性 Spark 把 1.5 亿美元迁到 V4，我认为意义远大于金额本身 真正值得关注的是： 开始有真实资金愿意采用 Hook 架构 过去很多 Hook 都停留在 Demo、Hackathon、PPT 现在开始进入真实部署 这才是市场真正关心的信号 未来我认为 Hook 会沿着几个方向快速发展： 收益增强（DualPool、Vault） 动态费率 JIT 流动性 Oracle Anti-MEV Settlement RWA 链上做市 AI Agent 未来每一个流动池，都可能拥有自己的 Hook 所以 V4 Hooks 不只是 Uniswap 的升级 它更像是 DeFi 下一轮基础设施升级 过去大家在造协议 未来大家会开始造 Hook 谁能把 Hook 做成真正的产品，谁能拿到真实流动性，谁就更有机会成为下一轮 DeFi Alpha Hook Summer 才刚刚开始。

Over 50 creators gathered at Tunnel Tokyo for an intense overnight sprint, leveraging HappyHorse—the world’s top-ranked AI video generation model—to produce 15-second cinematic commercials from concept to final cut. The challenge was clear: transform a bold, imaginative idea into a polished, AI-generated video—in a single night. 🏆 The Grand Prize was awarded to @d__quack for a brilliantly inventive concept: a device that harnesses the centrifugal force of your daily train commute to dry your clothes. 🚃👔 Made with HappyHorse 1.1, try it by yourself:

678 people walked into the 31st Baidu Hackathon. 355 Agents walked out. The top 20 builds hit the Black Horse Show, the live finale for shortlisted teams. 1 in 5 was a one-person team. Some had never written a line of code. All of them left as builders. 👀

XTruth Integrates with OKX Onchain Outcomes to Provide Onchain Result Adjudication for World Cup Prediction Markets Summary XTruth has now integrated with OKX Onchain Outcomes, providing result submission, dispute resolution, and onchain settlement support for its World Cup prediction markets. OKX Onchain Outcomes serves as the infrastructure for this edition's official OKX World Cup prediction event. The first batch of markets covers six major categories — including overall champion and Golden Boot — as well as all 104 individual matches throughout the tournament. XTruth: Bringing Real-World Outcomes Onchain, Credibly XTruth is an open optimistic oracle deployed on X Layer, focused on solving one problem: how to credibly submit and settle clearly defined, verifiable real-world event outcomes onchain. Every prediction market needs a clear final outcome. Under XTruth's mechanism, a proposer submits an event result according to preset rules, while other participants can verify the proposal during a dispute window and challenge incorrect results. If a proposal goes unchallenged during the dispute period, the result moves to final settlement; if a dispute arises, it's handled according to the protocol's adjudication process. All proposals, challenges, and settlement records are recorded onchain and are publicly verifiable. XTruth also uses economic incentives to encourage community participation in result adjudication. Proposers who submit correct results earn adjudication rewards, while disputers who successfully challenge incorrect proposals can earn rewards according to protocol rules. The first round of community proposer recruitment has been completed, and the initial cohort of participants has already begun submitting and verifying match results in World Cup–related markets, earning OKB rewards in the process. Shortening Settlement Cycles for Time-Sensitive Markets Traditional optimistic oracles typically set relatively long dispute periods. Once a proposal enters the dispute process, the market may also need to wait for additional voting or adjudication time. For sporting events, results are usually clear shortly after the match ends, and users want markets to settle as quickly as possible. For these time-sensitive scenarios with clearly defined outcomes, XTruth supports configuring dispute periods as short as a few minutes, reducing the wait time from result submission to final settlement. A shorter dispute period doesn't mean skipping verification. Proposers still must submit results according to the rules and data sources predetermined by the market, and disputers can still challenge incorrect proposals within the allotted time. XTruth aims to strike the right balance between settlement efficiency and result reliability for high-time-sensitivity markets. Beyond Sports: Expanding into More Real-World Scenarios Sports isn't the only application XTruth is built for. As long as an outcome is clearly defined, the data source is well established, and a verifiable conclusion is possible, the same mechanism can be applied to macroeconomic events, onchain metrics, and entertainment data, among other scenarios. For example, whether a central bank rate decision resulted in a rate cut, whether a given chain's TVL exceeded a preset threshold at a specific point in time, or whether a film's opening-weekend box office (per a specified data source) hit a target figure — all of these can be defined as events requiring onchain adjudication. Such markets need to clearly specify, at creation, the object being observed, the data source, the measurement methodology, and the deadline. XTruth is then responsible for supporting result submission, dispute resolution, and final settlement. Exchange OS is an open protocol for the X Layer ecosystem. For prediction markets and dApps that require real-world result adjudication, XTruth plans to offer standardized oracle integration capabilities. Airdrop Season 1 Is Now Live XTruth Season 1 has officially launched, with a total ecosystem incentive pool of 5 million XTR allocated this season to reward participants who make meaningful contributions to the ecosystem. After completing basic tasks and qualifying for participation, users can get involved in three ways: joining the Hook x World Cup Hackathon to build a V4 Hook; completing designated tasks during the BillionLive World Cup season; or deploying and trading tokens on Eulr. For detailed task requirements, contribution calculation methods, and reward distribution rules, please visit: Becoming X Layer's Real-World Result Adjudication Layer XTruth's goal is to become the result adjudication layer connecting onchain markets with real-world events across the X Layer ecosystem. Starting with World Cup prediction markets, XTruth will continue to validate its open result submission, community challenge, and onchain settlement mechanisms. As more integrations come online, an expanding range of clearly defined, verifiable real-world events will be able to be asserted, verified, and settled on X Layer. XTruth 接入 OKX Onchain Outcomes，为世界杯竞猜市场提供链上结果裁定 XTruth 现已接入 OKX Onchain Outcomes，为其世界杯竞猜市场提供结果提交、争议处理与链上结算支持。OKX Onchain Outcomes 是本届 OKX 世界杯官方竞猜活动的基础设施。首批市场覆盖总冠军、金靴等六类主题，以及贯穿整届赛事的 104 场单场比赛。 XTruth：将现实结果可信地写入链上 XTruth 是部署于 X Layer 的开放式乐观预言机，专注于解决一个问题：如何将定义清晰、结果可验证的现实世界事件可信地提交并结算到链上。 每一个预测市场都需要明确的最终结果。在 XTruth 的运行机制中，proposer 根据预设规则提交事件结果，其他参与者可以在争议期内核验提案，并对错误结果发起挑战。如果提案在争议期内未被成功挑战，该结果将进入最终结算；如果发生争议，则按照协议设定的裁定流程处理。相关提案、挑战和结算记录均在链上留痕，可供公开核验。 XTruth 同时通过经济激励鼓励社区参与结果裁定。正确提交结果的 proposer 可以获得裁决奖励；成功挑战错误提案的 disputer 可以按照协议规则获得相应奖励。 第一轮社区 proposer 招募现已完成，首批参与者已经开始在世界杯相关市场中提交和核验比赛结果，并从中赚取okb奖励。 为高时效市场缩短结算周期 传统乐观预言机通常设置较长的争议期。当提案进入争议流程后，市场还可能需要等待额外的投票或裁定时间。 对体育赛事而言，结果通常在比赛结束后迅速明确，用户也希望市场能够尽快完成结算。针对这类结果明确、时效性要求较高的场景，XTruth 支持配置分钟级争议期，以缩短从结果提交到最终结算的等待时间。 更短的争议期并不意味着取消核验环节。proposer 仍需按照市场预先确定的规则和数据来源提交结果，disputer 也可以在规定时间内对错误提案发起挑战。 XTruth 希望在结算效率与结果可信度之间建立适合高时效市场的平衡。 从体育赛事走向更多现实场景 体育并不是 XTruth 唯一面向的应用方向。 在结果定义清晰、数据来源明确且具备可验证结论的前提下，同一套机制还可以用于宏观事件、链上指标和娱乐数据等场景。例如，某次议息会议公布的目标利率是否下调、某条链在指定时间点的 TVL 是否超过预设数值，或某部影片按指定数据源统计的首周末票房是否达到目标，都可以被定义为需要链上裁定的事件。 这些市场需要在创建时明确观察对象、数据来源、统计口径和截止时间。XTruth 则负责支持结果提交、争议处理与最终结算。 Exchange OS 是面向 X Layer 生态的开放协议。对于需要现实结果裁定的预测市场和 dApp，XTruth 计划提供标准化的预言机接入能力。 Airdrop Season 1 已开启 XTruth Season 1 现已启动，本季设置总计 500 万枚 XTR 的生态激励额度，用于回馈对生态作出有效贡献的参与者。 用户完成基础任务并获得参与资格后，可以通过三类方式参与：参加 Hook x World Cup Hackathon 并构建 V4 Hook；在 BillionLive 世界杯赛季中完成指定任务；或在 Eulr 上部署和交易代币。 具体任务要求、贡献计算方式及奖励分配规则请查看： 成为 X Layer 的现实结果裁定层 XTruth 的目标，是成为 X Layer 生态连接链上市场与现实事件的结果裁定层。 从世界杯竞猜开始，XTruth 将继续验证开放式结果提交、社区挑战和链上结算机制。随着接入场景增加，更多定义清晰、结果可验证的现实事件，将能够在 X Layer 上被断言、被核验并完成结算。 #Xtruth# #OKX# #Xlayer#
