剑桥另类金融中心（CCAF）最新研究显示，美国当前控制着全球比特币网络75.4%的哈希算力，较2021年中国主导时期（65-75%）更趋集中。这一数据源 自对49家头部挖矿企业的调查，其算力总和占据比特币全网近50%。XBIT表示随着美国成为全球最大挖矿中心，关于算力垄断可能威胁网络去中心化原则 的争议持续升温。 CCAF报告指出，美国当前算力规模达600 EH/s（占全球总量796 EH/s的75.4%），远超其他地区。这一格局的形成与政策导向密切相关——特朗普政府将比 特币视为"数字黄金"，并通过商务部"加速计划"简化矿场能源审批流程，吸引大量矿企迁入。然而，集中化趋势引发XBIT去中心化交易平台分析师担忧： 若未来美国政府调整立场，是否可能利用算力优势实施监管干预？ 历史提供了警示案例。2021年中国禁止挖矿后，算力短期内分散至全球，但最终仍向美国集中。尽管中国主导时期未发生网络滥用事件，但当前美国算力垄 断可能赋予联邦政府更大干预能力。例如，通过制裁或行政命令审查交易，甚至要求矿工执行特定区块筛选规则。XBIT去中心化交易所平台研究员坦 言："算力集中化可能使比特币面临'政治化'风险，这与中本聪设计的 ...

上周全球加密货币市场迎来显著反弹，比特币带领大盘及多数Altcoin走出连日阴霾。市场情绪指数从 55%跃升至79%，进入技术性多头区间，稳定币市值持续攀升，USDT与USDC分别达到1457亿和619亿 美元，涨幅达0.62%和2.32%，显示机构资金加速入场。XBIT去中心化交易所平台分析师指出，此轮上 涨主要受美国政策转向信号与市场超跌修复驱动，但经济衰退隐忧仍制约长期反转。 图源:币界网 上周市场反弹的核心动力来自美国对华关税态度缓和、特朗普承诺留任美联储主席鲍威尔，以及新任 SEC主席Paul Atkins对加密行业的友好表态。政策不确定性缓解刺激投资者风险偏好回升，美国资金成 为主力推手。不过，XBIT去中心化交易所平台分析师警告称，当前反弹仅为前期超跌修复，全球经济 衰退风险与贸易政策变数仍将限制涨幅。 Solana基金会近期推出去中心化验证者激励新政，要求基金会委托的验证者需满足"社区质押占比低于 1000 SOL"等条件，以削弱中心化质押垄断。该政策推动链上去中心化指标提升，验证者数量周增 12%。与此同时，XBIT链上稳定币流动性的改善正吸引更多机构部署Solana生态，包括跨链桥资产流入 ...
