S1E14|智能合约钱包为Web3引入10亿用户?EOA/CA/账户抽象科普

from Web3 101 · host Web3 101

随着Vitalik推广基于ERC-4337的账户抽象方式,「Web3的10亿用户将由智能合约钱包带来」的想法再次在圈内被讨论,gas费代付,无需助记词等新功能亮点受到关注。而同时,相比上前几年,钱包作为入口的叙事也已发生转变。 对于普通用户来说,「钱包」和「地址」的概念都还没捋清,面对EOA/CA/账户抽象这些术语更是一头雾水,这次我们就试图解释和梳理出他们的关系。 主播|阿伟 Awaei ,Twitter:@web3awaei 嘉宾|知县,UniPass创始人,Twitter:@frank_lay2 【你将听到】 02:37今天Web3的用户远少于97年互联网用户 03:42「钱包」不是个好类比,拆分3层重新理解 07:36钱包VS地址,是两个容易混淆的概念 09:36EOA是什么?MetaMask其实是个开发者工具 11:27CA是什么?为什么需要手动导入小众Token? 14:19智能合约钱包其实是个老概念 15:00账户抽象的来历,为什么ERC-4337受重视? 25:12从底层对比EOA和智能合约钱包的区别 31:36智能合约钱包可以不用助记词?如何社交恢复? 35:23智能合约钱包面对的问题;兼容、安全、成本 40:53钱包是入口的叙事已经变了 45:15智能合约钱包的流行或许不依赖手机 50:22钱包的实现难度和承担责任可能被低估了 【相关阅读】 Stop Calling it a Wallet 名词解释:Web3 账户相关概念大梳理 知县瓦猫之夏分享PPT(钱包的分层结构) 账户抽象的动机、历史和分析 低门槛钱包——大众大规模采用Web3应用的必要工具 Web3 世界的通行证 — 钱包到底是什么? 【相关概念】 EOA(Externally Owned Accountsœ):外部账户,MetaMask生成的地址就是EOA CA(Contract Accounts):合约账户(也曾被称为内部账户),ERC-20 代币合约、DeFi 业务合约等都有一个跟EOA长得很像的地址,这就是CA。 SCW/A( Smart Contract Wallet/Account):智能合约钱包 ,也就是用CA作为地址的钱包方案,而我们常用的EOA钱包方案是用前述的公钥变换结果作为地址。由于具备内部逻辑,智能合约钱包可以实现很多EOA无法实现的功能,比如gas代付,批量交易,权限管理,离线授权,社交恢复等等。 Account Abstraction:账户抽象。 【BGM】 Mumbai — Ooyy 【后期】 Amei 【在这里找到我们】 中国用户:苹果播客|小宇宙 海外用户:Apple Podcast|Google Podcast|Amazon Music|Spotify Twitter:@Web3_101 【嘉宾言论仅代表个人,本期节目不构成任何投资建议哦】
