3 月 29 日,以太坊创始人 Vitalik Buterin 今日发表长文《A simple L2 security and finalization roadmap》「一个简单的 L2 安全与最终化路线图」,文中指出以太坊 L2 安全性与最终性优化的三大核心方向:


扩容数据容量:通过 Pectra 升级将 Blob 空间提升至 6 个,并在年底 Fusaka 升级中扩展至 72 个(或分阶段增至 12-24 个),满足 L2 交易吞吐量需求;


混合证明系统实现快速最终性:采用 2/3 多签机制(乐观证明+ZK 证明+TEE 可信硬件证明),若 ZK 和 TEE 同时验证则立即终局,单一验证则需结合 7 天乐观挑战期,安全委员会可紧急升级证明逻辑但受 30 天延迟限制,平衡即时终局与抗攻击能力;


构建统一 ZK 证明聚合层:标准化全生态证明聚合协议,允许多个应用共享单次证明成本(如 50 万 Gas),大幅降低 ZK 验证开销,推动 L2、隐私协议等场景普及。


该路线图目标是通过短期混合验证机制实现 L2 跨链桥接 1 小时内终局并降低费用,同时以长期全 ZK 化目标逐步淘汰 TEE 依赖,最终建立高效、安全且去信任的 L2 生态。
