# 源码解析：
以太坊中的MPT
以太坊中的所有的merkle树都是指Merkle Patricia Tree。

从区块头中可以看到有3棵MPT的根。

stateRoot
transcationsRoot
receiptsRoot

## State树
State树是一棵全局的树，它的key是sha3(ethereumAddress),即账户地址的hash值。其存储的值value为rlp(ethereumAccount)，即账户信息的rlp编码。其中账户信息是一个[nonce,balance,storageRoot,codeHash]的四元组，其中storageRoot指向账户的Storage树。

## Storage树
一般的外部账户Storage为空，而合约账户通常会储存一定的数据，这些数据就是存储在合约账户的Storage树中，storage树中的key与账户地址和其中实际存储的key有关，其value值为合约定义的value值。

## Transactions树
每一个区块都会有一棵Transactions树，其key为rlp(transactionIndex)(交易在区块中的编号，0，1…),其value值为经过rlp编码的交易。在实际情况中该树并不会真的存储到数据库中，只是在生成block以及校验block的时候用于得到当前区块的TransactionsRoot。

## Receipts树
每一个区块都会有一棵Receipts树树，其key为rlp(transactionIndex)(交易在区块中的编号，0，1…),其value值为经过rlp编码的交易收据。在实际情况中该树并不会真的存储到数据库中，只是在生成block以及校验block的时候用于得到当前区块的ReceiptsRoot。

## 文档
- eip-4337文档：4337的规范。https://eips.ethereum.org/EIPS/eip-4337
- sdk：提供了构建UserOperation，推送UserOperation的能力。源码位于https://github.com/eth-infinitism/bundler/tree/main/packages/sdk。
npm包位于
https://www.npmjs.com/package/@account-abstraction/sdk。

- bundler：收集UserOperation，验证并推送到EntryPoint合约。git地址https://github.com/eth-infinitism/bundler
- contracts： 主要是EntryPoint，验证UserOperation，并调用AA账户的业务逻辑。git地址https://github.com/eth-infinitism/account-abstraction
