ChainCatcher 消息,Vitalik 在 X 平台发文表示,以太坊自 2016 年初以来一直在讨论账户抽象(AA),现在 EIP-8141 作为一项综合性提案,旨在解决 AA 所涉及的所有剩余问题。该提案的核心概念为“帧事务”,一个事务包含 N 个调用,可读取彼此的调用数据,并能够授权发送方和 gas 支付方。
该机制支持多种使用场景:普通账户交易(如多重签名、可变密钥、抗量子签名方案)通过验证帧和执行帧完成;使用非 ETH 代币支付 gas 费时,可通过支付主合约实现,无需任何中介机构;
隐私协议方面,可通过支付合约验证 ZK-SNARK 或添加二维随机数来实现。在安全性方面,链上层面仅在验证帧返回带有支付 gas 标志的 ACCEPT 时交易才有效,内存池层面初期将采用保守规则,后续逐步扩展。
