倍的方案，并认为此举可能与其对相关技术使用情况的担忧有关。\n\n他称此事涉及潜在法律责任，认为 DFINITY 及 ICP 社区因此受到损害，并希望双方能够解决争议。上述内容目前属于 DFINITY 创始人的单方面指控，相关技术使用是否构成侵权，以及 NEAR 是否存在其所称的安全与去中心化问题，仍有待进一步核实。

epoch 约 3.75 个基点的幅度线性递减，并保留 90/10 的质押者与国库分配比例。投票通过后设有 90 天宽限期，随后正式启动递减。提案测算显示，该方案预计在两年内减少约 1180 万枚 NEAR 发行，六年累计减少约 6610 万枚，相当于供应量较现状缩小 4.36%。质押年化收益率将从当前的 5.268% 逐步降至 3.372%。作者指出，此举旨在降低非质押持有者被稀释的程度，并回应此前 Sovereign Fund 提案撤回后关于协议不应内化自由裁量风险的讨论。该提案需经过双重流程才能生效：House of Stake 投票通过后，验证者还需通过标准协议升级流程独立采纳。提案引用了 Solana 于 2026 年 8 月通过的 SGP-0002 作为先例，后者以 67.001% 的质押权重批准了类似发行削减。目前 NEAR 网络共有 406 个活跃验证者，质押率为 42.71%。

Intents 总经理 Alex Shevchenko 于 10 月 16 日发布，称攻击者在 10 月 1 日协议关停前提取了 380 万美元，并在检测后 36 小时内归还全部资金，所有受影响用户已获全额补偿。报告显示，该功能会在代币存入时通知第三方合约。攻击者创建了一个故意让通知失败的合约，使代币合约退还存款，而 NEAR Intents 仍保留对应的账本信用额度。在 23 笔失败存款交易中，攻击者累积了 380 万美元无支撑余额，报告称之为 ghost funds，随后据此提取真实代币，并通过 Omni 基础设施转移至其他链。Shevchenko 表示，这是 NEAR Intents 合约的漏洞，而非 Omni 基础设施的漏洞。提款发生在 9 月 29 日至 10 月 1 日。结算合约于 10 月 1 日暂停并重新开放，受影响路由随后逐步恢复，合约侧存款于 10 月 2 日恢复。报告称，漏洞未被发现是因为监控仅比较原始链资产与 NEAR 侧代币总余额，未比较用户内部余额总和与合约实际持有的代币；团队已补充该检查，并在余额不一致时自动暂停合约。10 月漏洞的修复于 10 月 2 日部署，但同一功能另一起严重漏洞报告促使其于 10 月 7 日被完全移除，相关研究员获得 30 万美元奖励。
