用户钱包都采用 contract 实现，每个用户对应一个合约地址
用户初次发起交易时，会自动创建合约
用户可以指定一个 payment 合约地址，用该地址中的余额支付手续费
整体架构
ERC-4337 定义了一个基于 ETH 的账户抽象标准，以下为简单介绍。
UserOperation：类比原生交易，不过为另一种格式的交易，比如支持携带自定义签名、交易的基础信息（gas、sender、limit等）
UserOperation mempool：专门的一些节点搭建的P2P网络构成的交易缓存池，用于接受UserOperation
Bundler：负责收集、校验、打包UserOperation，并将打包好的交易发送给产块人，交易上链的费用由Bundler支付，但是Bundler会从UserOperation中获取用户的手续费作为奖励。
Note：本质上是启动了一个独立于主链的P2P网络，用于接收抽象账户的交易并打包上链。

重点关注的两件事情：
如果计算、校验，即交易做了哪些操作，是否合法
每个操作的收费是如何定价的，包括：读取、存储、计算。
tx 会产生所有状态读取/写入、签名验证以及与 tx 大小成比例的成本的 gas 成本。运营商在启动节点时会设定最低 gas 价格。
需要消耗 gas的交易类型每个交易在执行过程中都会消耗一定数量的Gas，该Gas用于跟踪执行过程中的资源消耗。在Cosmos SDK应用程序中，交易可以是发送消息（Message）的操作，例如
发送代币
执行智能合约
当执行这些消息时，相关的Gas会被消耗，并且可能会生成相应的费用（Fees）。
请注意，Gas的消耗和费用的生成通常由应用程序开发者定义和管理，可以根据具体的应用逻辑和需求进行设置。

第一阶段EIP4844 主要即为第一个阶段所要完成的工作。主要包括：
1.新增一种交易类型，该交易类型新增了一种字段：blob，为该字段设置单独的gas收费标准，且收费较低，rollup 可采用该字段存储数据
2.新增blob会增大区块数据量，新增历史数据清理功能，超过30天的blob数据可以从节点移除，或迁移至第三方去中心化存储
3.blob与 tx 存储分离，并通过一个 commitment 来进行关联，commitment采用 KZG 算法来实现，KZG 算法可以看做类似 merkle 树的证明算法
4.KZG 在 sharding 中扮演着重要的角色，Rollup 校验中除了 KZG，采用别的验证算法都无法达到很好的效果。

目的EIP-4844的主要目的是在不牺牲去中心化的情况下，降低网络上的gas费用，特别是对rollup解决方案。Arbitrum和Optimism等rollup解决方案可以将gas费用降低100到1000倍。
EIP-4844 提案是作为以太坊2.0更新完成之前的临时解决方案。该提案解释了一种新方法，以帮助划分交易中所需的信息，如验证规则和交易格式，而无需实际实现任何分片。
这是一个很大的EIP，细分下来，需要用很多篇文章才能讲完整个EIP的细节经及EIP-4844要做的事。
背景每个区块 12 秒的出块时间 TPS 大概为 13~30 笔交易左右，但根据目前已知以太坊的 TPS 最高可以达到每秒 45 笔交易。以太坊做为最主流的区块链，这个TPS就非常拉夸，还要号称世界计算机。
所以想要成为 “世界计算机” 的以太坊每秒最多处理 45 笔交易的性能实在是太弱了。所以以太坊迫切需要扩容来解决性能问题。
以太坊由于智能合约的存在，每个交易的内容各不相同，所以每个区块可以处理多少笔交易（ ...</div></div></div><div class="recent-post-item"><div class="post_cover right"><a href="/posts/750b0a4e.html" title="使用IDEA开发rust提示file is not included in module tree"><img class="post_bg" src="/images/cover/cover-rust.jpeg" onerror="this.onerror=null;this.src='/img/404.jpg'" alt="使用IDEA开发rust提示file is not included in module tree"></a></div><div class="recent-post-info"><a class="article-title" href="/posts/750b0a4e.html" title="使用IDEA开发rust提示file is not included in module tree">使用IDEA开发rust提示file is not included in module tree</a><div class="article-meta-wrap"><span class="post-meta-date"><i class="far fa-calendar-alt"></i><span class="article-meta-label">发表于</span><time datetime="2023-04-18T18:08:57.000Z" title="发表于 2023-04-19 02:08:57">2023-04-19</time></span><span class="article-meta"><span class="article-meta-separator">|</span><i class="fas fa-inbox"></i><a class="article-meta__categories" href="/categories/rust/">rust</a></span></div><div class="content">问题用了很长一段时间nvim写rust，还没有用IDEA这样的IDE来写rust。就准备用一下，一用发现，还不太会在IDEA上用rust。碰到的第一个问题就是 IDEA 提示:

解决IDEA 用 rust 我也不熟，猜测应该是跟项目构建有关，就类似IDEA 使用 maven 的构建，也需要对应的设置一样。
右键一下 Cargo.toml看一下，还真有一个Attach Cargo Project这一项，然后只要把项目添加到 IDEA 中就可以：

rust当中，的两个重要概念：借用和生命周期分别代是在:
栈变量，需要关注【所有权】
引用(指针)，需要关注【生命周期】
Rust 的每个引用都有自己的生命周期，生命周期指的是引用保持有效的作用域。大多数情况下，引用是隐式的、可以被推断出来的，但当引用可能以不同的方式互相关联时，则需要手动标注生命周期。这里重点就是以不同的方式互相关联时。
大多数情况下，rust 可以自己推断出引用的生拿周期，也就是只有在一些rust无法自行推断的情况下，才需要手动标注生命周期。
生命周期Rust 中的每一个引用都有其生命周期（lifetime），也就是引用保持有效的作用域。大部分时候生命周期是隐含并可以推断的，正如大部分时候类型也是可以推断的一样。类似于当因为有多种可能类型的时候必须注明类型，也会出现引用的生命周期以一些不同方式相关联的情况，所以 Rust 需要我们使用泛型生命周期参数来注明 ...</div></div></div><div class="recent-post-item"><div class="post_cover right"><a href="/posts/3e7235c0.html" title="rust-vim 整合基于vimspector的debug调试环境"><img class="post_bg" src="/images/cover/cover-rust.jpeg" onerror="this.onerror=null;this.src='/img/404.jpg'" alt="rust-vim 整合基于vimspector的debug调试环境"></a></div><div class="recent-post-info"><a class="article-title" href="/posts/3e7235c0.html" title="rust-vim 整合基于vimspector的debug调试环境">rust-vim 整合基于vimspector的debug调试环境</a><div class="article-meta-wrap"><span class="post-meta-date"><i class="far fa-calendar-alt"></i><span class="article-meta-label">发表于</span><time datetime="2023-02-27T15:17:08.000Z" title="发表于 2023-02-27 23:17:08">2023-02-27</time></span><span class="article-meta"><span class="article-meta-separator">|</span><i class="fas fa-inbox"></i><a class="article-meta__categories" href="/categories/rust/">rust</a><i class="fas fa-angle-right article-meta-link"></i><a class="article-meta__categories" href="/categories/vim/">vim</a><i class="fas fa-angle-right article-meta-link"></i><a class="article-meta__categories" href="/categories/vim/ide/">ide</a><i class="fas fa-angle-right article-meta-link"></i><a class="article-meta__categories" href="/categories/rust/ide/">ide</a><i class="fas fa-angle-right article-meta-link"></i><a class="article-meta__categories" href="/categories/vim/rust/">rust</a></span></div><div class="content">前言前面配置好rust开发环境后，还需要一个调试功能就能用了。不清楚的可以回看我的rust-vim安装记录调试器，找了几款，最后还是觉得还是使用vimspector这个用的习惯，捣鼓两个整合了一下基于vimspector的调试环境，快捷键不用重新再配置。
