<h3>🧠 Chainlink (LINK) 项目简介</h3>
<p class="ds-markdown-paragraph">Chainlink 是一个<strong>去中心化的预言机网络</strong>，它的核心功能是连接区块链上的智能合约与链下（现实世界）的数据。</p>
<p class="ds-markdown-paragraph">简单来说，区块链是一个相对封闭的环境，智能合约无法直接获取外部的信息（比如某场比赛的结果、某只股票的价格）。Chainlink 就充当了一个<strong>可信的桥梁</strong>，将这些外部数据安全可靠地传递给智能合约，使其能根据真实世界的事件触发和执行 。</p>
<h3>📈 近期价格走势</h3>
<ul>
<li>
<p class="ds-markdown-paragraph"><strong>24小时走势</strong>：数据存在差异，部分平台显示下跌约 <strong>3%</strong> ，也有平台显示上涨约 <strong>1%</strong> 。</p>
</li>

<p class="ds-markdown-paragraph"><strong>7天走势</strong>：同样存在差异，有平台数据显示下跌 <strong>6.4%</strong> ，也有数据显示上涨 <strong>5.48%</strong> 。</p>
</li>
<li>
<p class="ds-markdown-paragraph"><strong>30天走势</strong>：数据显示上涨约 <strong>3.86%</strong> 。</p>
</li>
<li>
<p class="ds-markdown-paragraph"><strong>历史最高价 (ATH)</strong>：约 ₩73,819 &#8211; ₩77,778 。</p>
</li>
<li>
<p class="ds-markdown-paragraph"><strong>历史最低价 (ATL)</strong>：约 ₩160 &#8211; ₩235 。</p>
</li>
</ul>
<blockquote>
<p class="ds-markdown-paragraph">总的来说，Chainlink 作为连接区块链与现实世界数据的关键基础设施，在加密生态中扮演着重要角色。其兑韩元的价格随市场整体行情实时波动，不同交易平台的报价也存在一定差异。</p>

                        <p>币搜网消息，4 月 7 日，摩根大通资产管理主席 Michael Cembalest 发布最新报告，描述美伊海湾冲突如何从「清除邪恶」演变为各方皆损的局面。报告指出投资者对伊朗局势存在两大主要误判。 首先市场误判了美国的能源独立（作为净出口国）能成为抵御海峡封锁或油价冲击的「防火墙」。但实际并非如此——美国化石燃料仍占最终能源消费的 85%，全球油价上涨会以超过 100% 的传导率直接推高美国国内原油、汽油、航煤等价格，天然气以外的多种碳氢化合物价格涨幅甚至高于欧洲和亚洲。 其次市场低估了伊朗通过「挟持全球经济」的策略成本与效果，对局势缓和的预期过于乐观。伊朗已发现控制海峡比想象中更廉价且有效，因此没有快速退让的压力。 Cembalest 在报告中强调，快速转向可再生能源以减少化石燃料依赖在当前速率下需要 10-15 年，属于「狂热幻想」。整体而言这场冲突暴露了美国军事与能源策略的局限性，没有明显赢家。Cembalest 还提醒投资者需警惕系统性风险。</p>

                        <p>据 1M AI News 监测，英伟达于 2025 年 12 月宣布收购 SchedMD 公司，该公司是开源作业调度软件 Slurm 的主要开发者，而 Slurm 广泛用于管理超级计算机和 AI 数据中心的计算任务调度，据称全球约 60% 的超级计算机都在使用它，包括 Anthropic、Meta、Mistral 等公司的 AI 训练集群，以及多国政府用于天气预报和核武器开发的超级计算机。Slurm 特别擅长管理英伟达芯片，但在非英伟达硬件上也有大量应用。 这一收购近期开始引发 AI 专家和超级计算机用户的担忧，他们担心英伟达可能会通过软件更新 subtly 偏向自家芯片（如 CUDA 和 InfiniBand），从而让 AMD、Intel 等竞争对手的硬件性能受损。部分人士引用英伟达此前收购 Bright Computing 的案例，认为类似整合可能导致其他芯片出现性能惩罚。Intersect360 Research CEO Addison Snell 表示，担忧在于英伟达可能将这个通用的开源工具改造为「更适合或专属自家硬件」的产品，影响公平竞争。 英伟达回应称，Slurm 仍是开源软件，公司将继续为所有用户提供增强和支持，强调其致力于「开源、厂商中立」的开发，并表示客户会普遍受益。公司计划维持对 SchedMD 数百家客户的培训和技术支持，同时否认过去收购会损害多硬件兼容性。这一事件被视为检验 Nvidia 在 AI 和高性能计算领域是否真正保持开放的重要测试。</p>
