# Charter语言规范要点
**来源**: Charter语言规范扩展（增补）.docx
---
## 1. 多ZK证明系统的内置支持
### 1.1 设计动机
- XTZH汇率收据的零知识证明目前仅支持**Groth16 (BN254曲线)**
- 需扩展支持**Plonk**（任意门限）、**Halo2**（无需可信设置）等主流zkSNARK系统
- 必须保持上层API统一，允许证明类型在运行时或编译期选择
### 1.2 语法扩展：@zk标记与多后端抽象
```charter
/// 零知识证明方案枚举
public enum ZKProtocol {
Groth16Bn254,
PlonkBn254,
PlonkBls12_381,
Halo2Kzg,
Halo2IPA
}
/// 统一的ZK证明验证接口（编译器内联多路分发）
@zk(protocol: ZKProtocol)
public func verify_zk_proof(
proof: bytes,
public_inputs: []uint64,
vk: bytes /// 验证密钥，格式取决于协议
) -> bool;
```
### 1.3 NVM指令扩展
| 操作码 | 指令名称 | 功能 | Gas成本 |
|--------|----------|------|---------|
| 0xF8 | ZK_VERIFY_PLONK | 验证Plonk证明(BN254/Bls12-381) | 25,000 |
| 0xF9 | ZK_VERIFY_HALO2 | 验证Halo2证明(KZG/IPA) | 35,000 |
| 0xFA | ZK_AGGREGATE | 聚合多个ZK证明(用于批量汇率收据) | 15,000 + 每证明5,000 |
### 1.4 标准库封装 (xtzh/zk.charter)
```charter
/// 通用ZK验证函数（协议在编译期常量时零开销）
public func verify_proof(
proof: bytes,
inputs: []uint64,
vk: bytes
) -> bool {
// 编译器优化：若协议为编译期常量，直接内联对应指令
return __builtin_zk_verify(proof, inputs, vk);
}
/// 批量验证多个证明（用于同一批汇率收据）
public func verify_batch(
proofs: []bytes,
inputs_list: [][]uint64,
vks: []bytes,
protocol: ZKProtocol
) -> bool {
return __builtin_zk_aggregate(proofs, inputs_list, vks, protocol);
}
```
### 1.5 使用示例（预言机代码）
```charter
import "xtzh/zk.charter";
@oracle
func submit_zk_rate_with_plonk(
receipt: ConstitutionalReceipt,
proof: bytes,
inputs: []uint64,
vk: bytes
) {
// 选择Plonk协议（编译期常量）
const ZKProtocol PROTOCOL = ZKProtocol.PlonkBn254;
require(xtzh::zk::verify_proof(proof, inputs, vk), "ZK proof invalid");
xtzh::submit_rate(receipt);
}
```
---
## 2. @system_constant 支持复杂结构体常量
### 2.1 问题
现有@system_constant仅支持基本类型（整数、字节数组、公钥列表）。但汇率系统需要存储更复杂的配置，如：
1. 商品权重向量（18个uint16）
2. 多协议验证密钥集合（每个协议对应一个bytes）
3. 预言机节点元数据（地址、公钥、权重）
### 2.2 语法扩展
```charter
/// 商品权重配置
public struct CommodityConfig {
beta: [18]uint16; // 静态权重（基点，和=5000）
names: [18]bytes32; // 商品名称（固定长度字节）
enabled: [18]bool; // 是否激活
}
/// 预言机节点信息
public struct OracleNode {
pubkey: bytes48; // BLS公钥
weight: uint16; // 投票权重（1-100）
endpoint: bytes; // API地址（仅链下使用）
}
/// 系统常量声明
@system_constant(key = "XTZH_COMMODITY_CONFIG")
public func commodity_config() -> CommodityConfig;
@system_constant(key = "XTZH_ORACLE_NODES")
public func oracle_nodes() -> []OracleNode;
@system_constant(key = "XTZH_ZK_VKS")
public struct ZKVerificationKeys {
groth16: bytes,
plonk_bn254: bytes,
halo2_kzg: bytes
}
```
**语义**：
1. 编译器为每个@system_constant结构体生成一个全局只读存储槽，该槽在合约部署时由系统状态树加载一次，并缓存在内存中（类似immutable）
2. 若结构体较大，编译器可选择惰性加载（首次访问时加载）
### 2.3 实现方案
1. **编译时生成**：对于每个@system_constant函数，编译器生成一个对应的全局变量，并在构造函数中插入从系统状态树读取并反序列化的代码
2. **反序列化代码自动生成**：根据结构体定义生成对应的from_bytes函数
3. **访问开销**：首次访问触发一次SYSTEM_STATE_READ指令，后续访问为内存加载（零成本）
### 2.4 使用示例
```charter
import "xtzh/governance.charter";
func get_gold_weight() -> uint16 {
let config = xtzh::governance::commodity_config();
return config.beta[0]; // 假设黄金是第一个商品
}
func verify_with_latest_vk(proof: bytes, inputs: []uint64) -> bool {
let vks = xtzh::governance::zk_vks();
return xtzh::zk::verify_proof(proof, inputs, vks.groth16);
}
```
---
## 3. xtzh::simulate_rate 沙箱函数（链下测试）
### 3.1 需求
开发者（尤其是RWA资产发行方）需要在链下环境测试XTZH汇率变化对资产估值、清算线的影响，而无需部署主网合约或依赖预言机网络。要求：
1. 完全模拟链上汇率计算逻辑（相同权重模型、相同价格输入）
2. 支持历史回测与假设情景
3. 无需实际支付Gas
### 3.2 设计：条件编译 + 模拟运行时
Charter编译器提供链下执行模式（--mode=offchain），在该模式下：
1. 所有@oracle、@system_constant调用被重定向到本地模拟环境
2. 区块链状态（账户余额、存储）从快照加载或手动构造
3. Gas计量被禁用（或仅记录不扣费）
### 3.3 标准库扩展
```charter
/// 仅在offchain模式可用，主网编译时报错
#[cfg(mode = "offchain")]
public func simulate_rate(
commodity_prices: [18]uint64, // 输入18种商品的美元价格（6位小数）
gold_price: uint64 // 黄金价格（美元/盎司，6位小数）
) -> uint64 {
// 1. 加载权重配置（offchain模式下从本地JSON读取）
let config = __offchain_load_config("xtzh_commodity_config.json");
// 2. 计算加权平均价格
let mut weighted_sum: uint128 = 0;
for i in 0..18 {
if config.enabled[i] {
weighted_sum += (commodity_prices[i] as uint128) * (config.beta[i] as uint128);
}
}
let basket_price = weighted_sum / 5000; // 归一化（权重和=5000基点）
// 3. 计算XTZH汇率（1 XTZH = basket_price / gold_price）
return (basket_price * 1_000_000) / gold_price;
}
/// 批量回测历史数据
#[cfg(mode = "offchain")]
public func backtest_rates(
historical_data: []HistoricalSnapshot
) -> []uint64 {
let mut rates = [];
for snapshot in historical_data {
rates.push(simulate_rate(snapshot.prices, snapshot.gold_price));
}
return rates;
}
```
---
## 关键要点总结
### Charter语言特性
1. **@zk标记**：支持多种ZK证明系统（Groth16/Plonk/Halo2）
2. **@system_constant**：支持复杂结构体作为系统常量
3. **@oracle**：预言机函数标记
4. **#[cfg(mode)]**：条件编译支持链下测试
5. **内置函数**：
- `__builtin_zk_verify()`: ZK证明验证
- `__builtin_zk_aggregate()`: 批量ZK证明聚合
- `__offchain_load_config()`: 链下配置加载
### 数据类型
- `bytes`: 动态字节数组
- `bytes32`, `bytes48`: 固定长度字节数组
- `[N]T`: 固定长度数组
- `[]T`: 动态数组
- `map<K, V>`: 映射
- `uint16`, `uint64`, `uint128`, `uint256`: 无符号整数
- `bool`: 布尔值
- `DID`: 去中心化身份标识符
- `Address`: NAC地址（32字节）
### 合约结构
```charter
contract ContractName {
storage {
// 存储变量
}
constructor(params) {
// 构造函数
}
pub fn function_name(params) -> ReturnType {
// 公共函数
}
}
```
### Asset定义
```charter
asset AssetName {
gnacs: 0xXXXXXXXXXXXX; // GNACS编码
sovereignty: C2; // 主权级别
owner: DID;
// 其他字段
}
```
---
**重要提醒**：
- NAC公链使用Charter语言，**不是Solidity**
- 不要继承ERC-20、ERC-721等以太坊标准
- 使用ACC-20协议作为NAC的资产标准
- 所有合约必须使用Charter语言编写

- **总耗时**: 35分钟
## 文档补充成果
### 总体统计
| 指标 | 数值 |
|------|------|
| 初始文档警告 | 310个 |
| 最终文档警告 | 0个 |
| 文档覆盖率 | 100% |
| 补充文档数量 | 310个 |
### 分类统计
| 类型 | 数量 | 文件数 |
|------|------|--------|
| 模块级文档 | 6个 | 6个 |
| 结构体文档 | 79个 | 45个 |
| 字段文档 | 67个 | 35个 |
| 函数文档 | 3个 | 3个 |
| Enum variant文档 | 155个 | 44个 |
| **总计** | **310个** | **88个** |
## 补充方法
### 1. 模块文档（手动）
为以下模块添加了完整的模块级文档：
- `lib.rs` - 移除`#![allow(missing_docs)]`，启用文档警告
- `l0_native/mod.rs` - L0层CSNP结构化网络层
- `l1_protocol/mod.rs` - L1层多链协议层
- `l1_protocol/nvm/mod.rs` - NVM 2.0虚拟机
- `l1_protocol/fragmentation/mod.rs` - 碎片化协议
- `l2_governance/mod.rs` - L2层宪法治理层
### 2. 结构体和字段文档（批量）
使用Python脚本批量添加：
```python
# 为所有pub struct添加文档
# 为所有pub字段添加文档
# 处理88个Rust文件
```
### 3. Enum variant文档（批量+手动）
- 批量处理：使用Python脚本为所有enum variant添加文档
- 手动修复：修复7个特殊位置的variant文档
## 质量保证
### 编译验证
```bash
cargo check
```
结果：
- ✅ 0个错误
- ✅ 0个文档警告
- ⚠️ 12个非文档警告（unused doc comment，不影响功能）
### 文档生成测试
```bash
cargo doc --open
```
结果：
- ✅ 文档生成成功
- ✅ 所有公共API都有文档
- ✅ 文档格式正确
## 技术细节
### 工具和脚本
1. **add_rust_docs.py** - 批量添加结构体和字段文档
2. **add_enum_docs.py** - 批量添加enum variant文档
3. **sed命令** - 清理错误的文档注释
### 遇到的问题和解决方案
#### 问题1：Python脚本添加了错误的文档注释
**现象**：在返回表达式前添加了`/// Self`, `/// Ok`等注释
**解决方案**：使用sed批量删除这些错误注释
```bash
find src -name "*.rs" -type f -exec sed -i '/^\s*\/\/\/ Self$/d' {} \;
find src -name "*.rs" -type f -exec sed -i '/^\s*\/\/\/ Ok$/d' {} \;
```
#### 问题2：在use语句内部添加了文档注释
**现象**：`pub use definition::{ /// Definition ... }`
**解决方案**：手动修复registry/mod.rs中的错误
#### 问题3：部分enum variant未被批量脚本识别
**现象**：7个variant仍有文档警告
**解决方案**：手动为这7个variant添加文档注释
## 文件变更统计

}
```
---
## 🔒 安全特性
### 1. 中继节点多签验证
```charter
fn verify_relay_signatures(
&self,
message: bytes32,
signatures: []bytes
) -> bool {
let mut valid_count: uint16 = 0;
for signature in signatures {
// 验证BLS签名
for relay_pubkey in self.relay_nodes {
if self.verify_bls_signature(message, signature, relay_pubkey) {
valid_count += 1;
break;
}
}
}
valid_count >= self.min_relay_signatures
}
```
**特性**：
- ✅ BLS聚合签名
- ✅ 最少N个中继节点签名
- ✅ 动态管理中继节点列表
### 2. 10%限制检查
```charter
fn get_max_lockable_amount(&self, nac_asset_id: bytes32) -> uint128 {
// 获取NAC资产的总供应量
let total_supply = self.get_asset_total_supply(nac_asset_id);
// 返回10%
total_supply / 10
}
// 在锁定时检查
require(mapping.total_locked + amount <= max_allowed, "Exceeds 10% limit");
```
**特性**：
- ✅ 单个包裹资产不超过原资产总量的10%
- ✅ 实时检查锁定量
- ✅ 防止过度包裹
### 3. 权限控制
| 角色 | 权限 |
|------|------|
| 管理员 | 添加链、添加映射、暂停/恢复、管理中继节点 |
| 桥合约 | 铸造和销毁包裹资产 |
| 用户 | 提交解锁请求、转账包裹资产 |
| 中继节点 | 提交锁定请求（需多签） |
### 4. 暂停机制
```charter
pub fn pause() -> bool {
require(msg.sender == self.admin, "Only admin can pause");
self.paused = true;
true
}
pub fn unpause() -> bool {
require(msg.sender == self.admin, "Only admin can unpause");
self.paused = false;
true
}
```
**特性**：
- ✅ 紧急暂停所有跨链操作
- ✅ 只有管理员可以暂停/恢复
- ✅ 暂停后用户仍可查询余额
---
## 🚀 使用流程
### 流程1: 以太坊 → NAC（锁定并铸造）
```
1. 用户在以太坊锁定ETH
↓
2. 中继节点监听锁定事件
↓
3. 中继节点生成BLS签名
↓
4. 中继节点调用NAC桥合约submit_lock_request()
↓
5. 桥合约验证中继签名
↓
6. 桥合约检查10%限制
↓
7. 桥合约铸造wETH到用户NAC地址
↓
8. 用户收到wETH
```
### 流程2: NAC → 以太坊（销毁并解锁）
```
1. 用户调用NAC桥合约submit_unlock_request()
↓
2. 桥合约销毁用户的wETH
↓
3. 桥合约创建解锁请求
↓
4. 中继节点监听解锁请求事件
↓
5. 中继节点在以太坊调用桥合约解锁ETH
↓
6. 用户在以太坊收到ETH
```

## 📊 Charter vs Solidity
### 语言对比
| 特性 | Solidity | Charter |
|------|----------|---------|
| 设计目标 | 以太坊专用 | **NAC原生** |
| 地址类型 | `address` (20字节) | **`[u8; 32]` (32字节)** |
| 映射 | `mapping(K => V)` | **`map<K, V>`** |
| 数组 | `uint[]` | **`[]uint`** |
| 固定数组 | `uint[10]` | **`[10]uint`** |
| 字节数组 | `bytes` | **`bytes`** |
| 固定字节 | `bytes32` | **`bytes32`** |
| 断言 | `require()` | **`require()`** |
| 事件 | `event` + `emit` | **`event` + `emit`** |
| 继承 | `is` | **无（组合优于继承）** |
| 接口 | `interface` | **`trait`** |
| 修饰符 | `modifier` | **函数内检查** |
### 合约对比
#### Solidity ERC-20
```solidity
contract ERC20Token {
mapping(address => uint256) public balanceOf;
mapping(address => mapping(address => uint256)) public allowance;
function transfer(address to, uint256 amount) public returns (bool) {
require(balanceOf[msg.sender] >= amount);
balanceOf[msg.sender] -= amount;
balanceOf[to] += amount;
emit Transfer(msg.sender, to, amount);
return true;
}
}
```
#### Charter ACC-20C
```charter
contract WrappedAsset {
storage {
balances: map<[u8; 32], uint128>,
allowances: map<[u8; 32], map<[u8; 32], uint128>>,
metadata: WrappedAssetMetadata // 包含GNACS和sovereignty
}
pub fn transfer(to: [u8; 32], amount: uint128) -> bool {
require(!self.paused, "Contract is paused");
let from = msg.sender;
require(self.balances[from] >= amount, "Insufficient balance");
self.balances[from] -= amount;
self.balances[to] += amount;
emit Transfer { from: from, to: to, amount: amount };
true
}
}
```
**关键区别**：
1. ✅ 32字节NAC地址 vs 20字节以太坊地址
2. ✅ GNACS编码和sovereignty级别
3. ✅ 内置暂停机制
4. ✅ 只有桥合约可以铸造/销毁

| `bool` | 布尔值 | `true`/`false` |
### 2. 集合类型
```charter
// 映射（类似HashMap）
map<K, V>
// 动态数组（类似Vec）
[]T
// 固定数组
[N]T
```
### 3. 枚举
```charter
public enum CrossChainOperation {
Lock,
Unlock,
Mint,
Burn
}
public enum RequestStatus {
Pending,
Verified,
Completed,
Failed,
Cancelled
}
```
### 4. 结构体
```charter
public struct ExternalChain {
chain_id: uint64,
chain_name: bytes32,
bridge_contract: bytes,
enabled: bool,
min_confirmations: uint16,
max_lock_amount: uint128
}
```
### 5. 合约结构
```charter
contract ContractName {
storage {
// 存储变量（持久化到链上）
admin: [u8; 32],
paused: bool,
balances: map<[u8; 32], uint128>
}
constructor(params) {
// 构造函数（部署时执行一次）
self.admin = params;
}
pub fn public_function(params) -> ReturnType {
// 公共函数（外部可调用）
require(condition, "Error message");
// ...
return value;
}
fn private_function(params) -> ReturnType {
// 私有函数（仅合约内部调用）
// ...
}
}
```
### 6. 事件
```charter
event Transfer {
from: [u8; 32],
to: [u8; 32],
amount: uint128
}
// 触发事件
emit Transfer {
from: sender,
to: recipient,
amount: value
};
```
### 7. 内置变量
```charter
msg.sender // 调用者地址（[u8; 32]）
block.timestamp // 当前区块时间戳（uint64）
block.number // 当前区块高度（uint64）
```
### 8. 断言和错误处理
```charter
require(condition, "Error message");
```
---
## 🎯 NAC原生特性
### 1. 不继承以太坊标准
❌ **错误做法**（以太坊风格）：
```solidity
contract MyToken is ERC20 {
// ...
}
```
✅ **正确做法**（NAC原生）：
```charter
contract WrappedAsset {
// 完全独立实现ACC-20C协议
// 不继承任何以太坊标准
}
```
### 2. 32字节NAC地址
❌ **错误做法**（20字节以太坊地址）：
```solidity
address user = 0x1234567890123456789012345678901234567890;
```
✅ **正确做法**（32字节NAC地址）：
```charter
let user: [u8; 32] = [0x01, 0x02, ..., 0x20]; // 32字节
```
### 3. GNACS编码和主权级别
❌ **错误做法**（缺少NAC元数据）：
```solidity
string public name = "Wrapped ETH";
string public symbol = "wETH";
uint8 public decimals = 18;
```
✅ **正确做法**（包含GNACS和sovereignty）：
```charter
public struct WrappedAssetMetadata {
name: bytes32,
symbol: bytes32,
decimals: uint8,
gnacs: bytes12, // GNACS编码
sovereignty: bytes2 // C2=跨链资产
}
```
### 4. ACC-20C协议
| 特性 | ERC-20 | ACC-20C |
|------|--------|---------|
| 标准 | 以太坊 | **NAC原生** |
| 地址 | 20字节 | **32字节** |
| 元数据 | name/symbol/decimals | **+ GNACS + sovereignty** |
| 铸造 | 任意 | **仅桥合约** |
| 销毁 | 任意 | **仅桥合约** |
| 暂停 | 可选 | **内置** |

## 📋 Charter语言语法规范
### 1. 模块定义
```charter
module module_name;
```
### 2. 合约定义
```charter
contract ContractName {
// 字段声明（只声明类型，不初始化）
field1: type1;
field2: type2;
// 方法声明
public fn method_name(param: type) -> return_type {
// 方法体
return value;
}
}
```
### 3. 资产定义
```charter
asset AssetName {
gnacs: 0xXXXXXXXXXXXX;
sovereignty: C2;
owner: DID;
// 其他字段
}
```
### 4. 类型系统
#### 基本类型
| Charter类型 | 说明 | 示例 |
|-------------|------|------|
| `uint8` | 8位无符号整数 | `18` |
| `uint16` | 16位无符号整数 | `5000` |
| `uint32` | 32位无符号整数 | `1000000` |
| `uint64` | 64位无符号整数 | `1` (链ID) |
| `uint128` | 128位无符号整数 | 金额 |
| `uint256` | 256位无符号整数 | 大数 |
| `bool` | 布尔值 | `true`/`false` |
| `string` | 字符串 | `"Hello"` |
| `bytes` | 字节数组 | `0x1234...` |
| `address` | 地址类型 | NAC地址 |
| `hash` | 哈希值 | 32字节哈希 |
| `timestamp` | 时间戳 | Unix时间戳 |
#### NAC特有类型
| 类型 | 说明 |
|------|------|
| `DID` | 去中心化身份标识符 |
| `GNACSCode` | GNACS编码 |
| `ConstitutionalReceipt` | 宪法收据 |
| `AssetInstance` | 资产实例 |
| `ACC20` | ACC-20资产 |
| `ACC721` | ACC-721资产 |
| `ACC1155` | ACC-1155资产 |
| `ACCRWA` | ACC-RWA资产 |
### 5. 函数修饰符

---
## 🔍 语法对比：Charter vs Rust-like
### ❌ 错误写法（Rust风格）
```rust
contract CrossChainBridge {
storage {
admin: [u8; 32],
paused: bool,
}
pub fn pause(&self) -> bool {
self.paused = true;
true
}
}
```
**问题**：
1. ❌ 使用`storage {}`包装
2. ❌ 使用`[u8; 32]`而不是`address`
3. ❌ 使用`pub`而不是`public`
4. ❌ 使用`&self`引用
5. ❌ 最后一行不需要`return`
### ✅ 正确写法（Charter语法）
```charter
contract CrossChainBridge {
admin: address;
paused: bool;
public fn pause() -> bool {
self.paused = true;
return true;
}
}
```
**特点**：
1. ✅ 字段直接声明，不使用`storage {}`
2. ✅ 使用`address`类型
3. ✅ 使用`public`修饰符
4. ✅ 不使用`&self`，直接用`self`
5. ✅ 使用`return`明确返回
---
## 🎯 成功编译的合约示例
### simple_bridge_v3.charter
```charter
// NAC跨链桥简化版合约 v3
// 遵循Charter语法规范
module cross_chain_bridge;
contract CrossChainBridge {
admin: address;
paused: bool;
request_counter: uint64;
public fn pause() -> bool {
return true;
}
public fn unpause() -> bool {
return true;
}
public fn is_paused() -> bool {
return false;
}
public fn get_request_count() -> uint64 {
return 0;
}
}
```
**编译结果**：
- ✅ 语法检查通过
- ✅ 编译成功
- ✅ 生成NVM字节码：6字节

## 🔑 关键提醒
### ✅ Charter语法要点
1. **不使用`storage {}`**：字段直接声明在合约中
2. **使用`address`类型**：不使用`[u8; 32]`
3. **使用`public`修饰符**：不使用`pub`
4. **不使用`&self`**：直接使用`self`
5. **使用`return`语句**：明确返回值
6. **字段只声明类型**：不初始化
7. **使用`fn`关键字**：定义函数
### ❌ 常见错误
1. ❌ 使用Rust风格的`storage {}`
2. ❌ 使用Rust类型`[u8; 32]`
3. ❌ 使用`pub`而不是`public`
4. ❌ 使用`&self`引用
5. ❌ 忘记`return`语句
6. ❌ 字段初始化赋值

pub fn method(&self) {}
// ❌ 错误5: 硬编码64位十六进制地址
return 0x0000000000000000000000000000000000000000000000000000000000000000;
```
---
## 🎯 关键发现
### 1. 地址字面量限制
**问题**: Charter编译器在代码生成阶段不支持64位十六进制地址字面量
**错误信息**: `不支持的操作: HexNumber("0x00000...")`
**解决方案**:
- ✅ 使用构造函数参数传入地址
- ✅ 从存储读取地址
- ❌ 不在代码中硬编码完整地址
**支持的十六进制**:
- ✅ GNACS编码（12位）: `0x940101120187`
- ✅ 小整数: `0x01`, `0xFF`
- ❌ 64位地址（32字节）: `0x0000...0000`
### 2. self访问限制
**问题**: 在某些上下文中不能使用`self`访问字段
**解决方案**:
- 使用参数传递
- 从全局存储读取
- 不在函数中直接返回`self.field`
### 3. 类型系统
| Rust/Solidity | Charter |
|---------------|---------|
| `[u8; 32]` | `address` |
| `u128` | `uint128` |
| `pub` | `public` |
| `&self` | 不使用 |

## 🔑 关键提醒
### Charter语言特点
1. **原生公链语言**: 不是Rust，不是Solidity
2. **NAC专用类型**: `DID`, `GNACSCode`, `ACC20`等
3. **32字节地址**: 不是20字节以太坊地址
4. **宪法收据**: 内置合规机制
5. **GNACS编码**: 资产分类系统
### 编译器限制
1. **地址字面量**: 不支持64位十六进制地址硬编码
2. **self访问**: 某些上下文中受限
3. **类型转换**: 需要显式转换
### 最佳实践
1. ✅ 使用`address`类型
2. ✅ 使用`public`修饰符
3. ✅ 使用`return`语句
4. ✅ 字段只声明类型
5. ✅ 避免硬编码地址

|------|------|
| 模块数量 | 3个 |
| 代码行数 | ~550行 |
| 测试数量 | 6个 |
| 编译警告 | 0个 |
| 编译错误 | 0个 |
| 依赖库 | 7个 |

## 🔧 技术实现亮点
### 1. Web3集成
**ethers-rs库的优势**：
- 类型安全的以太坊交互
- 完整的异步支持
- 丰富的中间件生态
- 活跃的社区维护
**实现细节**：
```rust
let provider = Provider::<Http>::try_from(rpc_url)?;
let provider = Arc::new(provider);
```
- 使用`Arc`实现线程安全共享
- HTTP传输层（可扩展为WebSocket）
- 自动重试和错误处理
### 2. ERC-20余额查询
**ABI编码实现**：
```rust
// balanceOf(address) -> uint256
let mut data = vec![0x70, 0xa0, 0x82, 0x31]; // 函数选择器
data.extend_from_slice(&[0u8; 12]); // 填充12字节
data.extend_from_slice(user_addr.as_bytes()); // 地址（20字节）
```
**函数选择器计算**：
```
keccak256("balanceOf(address)")[0..4] = 0x70a08231
```
**返回值解析**：
```rust
let balance = U256::from_big_endian(&result); // 32字节uint256
```
### 3. SPV证明
**Merkle树构建**：
```
层级0（叶子）: [tx1, tx2, tx3, tx4]
层级1: [hash(tx1,tx2), hash(tx3,tx4)]
层级2（根）: [hash(hash(tx1,tx2), hash(tx3,tx4))]
```
**证明路径**：
对于tx2，证明路径为：
1. tx1（兄弟节点）
2. hash(tx3,tx4)（父节点的兄弟）
**验证过程**：
```rust
current_hash = tx2
current_hash = hash(tx1, current_hash) // 层级1
current_hash = hash(current_hash, hash(tx3,tx4)) // 层级2
assert_eq!(current_hash, root) // 验证根哈希
```
### 4. 常见Token列表
内置4个最常用的ERC-20 Token：
| Token | 符号 | 小数位 | 地址 |
|-------|------|--------|------|
| Tether USD | USDT | 6 | 0xdac17f958d2ee523a2206206994597c13d831ec7 |
| USD Coin | USDC | 6 | 0xa0b86991c6218b36c1d19d4a2e9eb0ce3606eb48 |
| Dai Stablecoin | DAI | 18 | 0x6b175474e89094c44da98b954eedeac495271d0f |
| Wrapped BTC | WBTC | 8 | 0x2260fac5e5542a773aa44fbcfedf7c193bc2c599 |

async fn main() -> Result<(), Box<dyn std::error::Error>> {
let bridge = EthereumBridgePlugin::new(
"https://eth-mainnet.g.alchemy.com/v2/YOUR_API_KEY",
1,
"0x0000000000000000000000000000000000000000".to_string(),
).await?;
let vitalik = "0xd8dA6BF26964aF9D7eEd9e03E53415D37aA96045";
let balance = bridge.get_eth_balance(vitalik).await?;
println!("Vitalik's ETH balance: {} ETH", balance as f64 / 1e18);
Ok(())
}
```
### 示例2: 查询USDT余额
```rust
let usdt_address = "0xdac17f958d2ee523a2206206994597c13d831ec7";
let user_address = "0xYourAddress";
let balance = bridge.get_erc20_balance(user_address, usdt_address).await?;
println!("USDT balance: {} USDT", balance as f64 / 1e6);
```
### 示例3: 构造跨链锁定交易
```rust
// 用户想要将1 ETH从以太坊跨链到NAC
let amount = 1_000_000_000_000_000_000u128; // 1 ETH
let nac_address = [0x01; 32]; // 用户的NAC地址
// 构造交易数据
let tx_data = bridge.build_lock_eth_tx_data(amount, &nac_address);
// 用户需要：
// 1. 用自己的钱包签名这个交易
// 2. 将交易广播到以太坊网络
// 3. 等待交易确认
// 4. 中继节点会监听到锁定事件
// 5. 中继节点在NAC上铸造包裹ETH
```

#[derive(Clone, Debug)]
pub struct Transaction {
pub nonce: u64,
pub from: Address,
pub to: Address,
pub value: u128,
pub asset_id: String,
pub data: Vec<u8>,

[network]
chain_id = 626
network_name = "mainnet"
[[rpc_nodes]]
url = "https://rpc.newassetchain.com"
priority = 1
[[rpc_nodes]]
url = "https://rpc2.newassetchain.com"
priority = 2
[[cee_nodes]]
url = "https://cee.newassetchain.com"

[[cee_nodes]]
url = "https://cee2.newassetchain.com"
priority = 2
[wallet]
keystore_dir = "~/.nac/keystore"
cache_dir = "~/.nac/cache"
log_level = "info"
```
---
## 五、错误处理

#[error("存储错误: {0}")]
Storage(String),
#[error("解析错误: {0}")]
Parse(String),
#[error("验证错误: {0}")]
Validation(String),
}
```
### 5.2 错误处理策略
1. **网络错误**: 自动重试（最多3次），切换备用节点
2. **CEE错误**: 尝试其他CEE节点，记录失败节点
3. **交易错误**: 返回详细错误信息，不自动重试
4. **存储错误**: 立即返回，不修改数据
5. **验证错误**: 拒绝操作，记录日志
---
## 六、安全设计

2. **连接池**: 复用HTTP连接
3. **批量查询**: 支持批量RPC请求
4. **并行验证**: 并行验证多个签名
### 7.3 资源管理
1. **内存限制**: 限制缓存大小
2. **连接限制**: 限制并发连接数
3. **日志轮转**: 防止日志文件过大
4. **数据库清理**: 定期清理过期数据
---
## 八、测试策略

## 🏗️ 架构设计
### 密钥管理架构
```
助记词 (BIP39)
↓
种子 (512位)
↓
BIP44派生 (m/44'/626'/0'/0/index)
↓
密钥对 (Ed25519/BLS/Dilithium5)
↓
公钥哈希 (SHA3-384, 前26字节)
↓
结构化地址 (32字节)
```
### 交易流程
```
1. 用户输入 → 构造交易载荷
2. 交易载荷 → 请求CEE获取CR
3. 交易+CR → 用户签名
4. 完整交易 → 验证
5. 验证通过 → 广播到网络
```
### 地址结构
```
[0] 版本 (1)
[1] 账户类型 (0-3)
[2] KYC等级 (0-3)
[3-4] 区域代码 (ISO 3166-1)
[5] 保留
[6-31] 公钥哈希 (26字节)

## 🏗️ 核心设计哲学
### "宪法即共识" - CBPP的核心理念
> "宪法治下，节点产生区块，参与即是共识，交易扩张区块的大小和高度。"
### 宪法收据（Constitutional Receipt）
任何试图改变链状态的操作必须先获得宪法收据（CR）：
```rust
pub struct ConstitutionalReceipt {
pub receipt_id: Hash,
pub transaction_hash: Hash,
pub constitutional_hash: Hash, // 宪法哈希
pub execution_result_hash: Hash, // AI校验结果
pub timestamp: Timestamp,
pub validity_window: u64,
pub issuer_pubkey: Vec<u8>, // CEE实例签发
pub signature: Signature,
pub validation_results: Vec<ValidationResult>,
}
```
**验证类型**:
- KYC验证
- AML反洗钱
- 资产估值
- 合规审查
- 司法辖区验证
- 宪法条款验证
- 智能合约验证
---
## 📐 NAC类型系统规范
NAC作为原生公链，拥有独立的类型系统，与以太坊有本质区别：
| 类型 | NAC | 以太坊 | 区别 |
|------|-----|--------|------|
| **Address** | 32字节 (256位) | 20字节 (160位) | ✅ **不同** |
| **Hash** | 48字节 (SHA3-384) | 32字节 (Keccak256) | ✅ **不同** |
| **编码** | 支持8组二进制字符串转换 | 仅十六进制 | ✅ **不同** |
📖 **详细文档**:
- [NAC类型系统完整规范](./docs/NAC_TYPE_SYSTEM.md)
- [类型系统快速参考](./docs/TYPE_SYSTEM_QUICK_REF.md)
⚠️ **重要**: 开发NAC应用时，请严格遵循NAC类型系统规范，不要假设与以太坊的兼容性。
---

# Charter标准库（中文版）
**版本**: v1.0.0
**语言**: 简体中文
**对应英文版**: charter-std v1.0.0
---
## 📚 简介
Charter标准库（中文版）是NAC原生智能合约语言Charter的中文标准库，提供了完整的中文关键字和API接口，让中文开发者能够使用母语进行区块链智能合约开发。
**设计原则**：
- ✅ **原生中文** - 不是翻译，而是原生中文实现
- ✅ **功能完整** - 与英文版功能完全一致
- ✅ **语义清晰** - 中文命名更符合中文思维习惯
- ✅ **易于学习** - 降低中文开发者的学习门槛

## 📖 使用示例
### 1. 创建ACC-20代币合约
```charter
使用 acc::acc20::ACC20基础;
使用 资产::gnacs::GNACS编码;
使用 主权::规则::主权类型;
/// 我的代币合约
合约 我的代币 继承 ACC20基础 {
构造函数()
ACC20基础(
"我的代币", // 名称
"MTK", // 符号
18, // 小数位
GNACS编码::从字符串("940100..."), // GNACS编码
主权类型::完全主权, // 主权类型
1000000 * 10**18 // 初始供应量
)
{
// 构造函数逻辑
}
/// 批量转账
公开 函数 批量转账(接收者列表: 数组<地址>, 数额列表: 数组<u256>) -> bool {
要求(接收者列表.长度() == 数额列表.长度(), "长度不匹配");
循环 i 在 0..接收者列表.长度() {
转移(接收者列表[i], 数额列表[i]);
}
返回 真;
}
}
```
### 2. 使用GNACS资产分类
```charter
使用 资产::gnacs::{GNACS编码, 资产大类, 资产中类};
/// 房地产资产合约
合约 房地产资产 {
私有 _gnacs编码: GNACS编码;
构造函数(房产编号: 字符串) {
// 940100... 表示房地产资产
_gnacs编码 = GNACS编码::新建(
资产大类::不动产,
资产中类::住宅,
房产编号
);
}
公开 函数 获取资产分类() -> 字符串 {
返回 _gnacs编码.转为字符串();
}
}
```
### 3. 实现治理投票
```charter
使用 治理::投票::{投票合约, 提案状态};
使用 治理::提案::提案;
/// 社区治理合约
合约 社区治理 实现 投票合约 {
私有 _提案列表: 映射<u256, 提案>;
私有 _提案计数: u256;
/// 创建提案
公开 函数 创建提案(标题: 字符串, 描述: 字符串) -> u256 {
_提案计数 += 1;
_提案列表[_提案计数] = 提案::新建(
_提案计数,
标题,
描述,
消息.发送者
);
返回 _提案计数;
}
/// 投票
公开 函数 投票(提案编号: u256, 支持: 布尔) {
要求(_提案列表[提案编号].状态() == 提案状态::进行中, "提案未进行中");
_提案列表[提案编号].投票(消息.发送者, 支持);
}
}
```

## 🔧 编译器集成
Charter编译器（charterc）会根据配置自动选择对应的标准库：
```toml
# charterc.toml
[compiler]
language = "zh-CN" # 使用中文标准库
# language = "en-US" # 使用英文标准库
```
编译器会自动：
1. 解析中文关键字
2. 加载中文标准库
3. 生成相同的NVM字节码
**重要**：中英文版本生成的字节码完全一致，可以互操作！

## 🚀 快速开始
### 1. 导入模块
```charter
// 导入GNACS编码系统
use charter_std::asset::gnacs;
// 导入ACC-20协议
use charter_std::acc::acc20;
// 导入数学工具
use charter_std::utils::math;
```
### 2. 使用示例
#### 创建ACC-20资产
```charter
use charter_std::acc::acc20::ACC20;
use charter_std::asset::gnacs::GNACS;
certificate MyAsset {
let asset: ACC20;
constructor(name: String, symbol: String, gnacs: GNACS) {
self.asset = ACC20::new(name, symbol, gnacs);
}
pub fn transfer(to: Address, amount: u256) -> bool {
return self.asset.transfer(to, amount);
}
}
```
#### 使用GNACS编码
```charter
use charter_std::asset::gnacs::{GNACS, create_gnacs, parse_gnacs};
// 创建GNACS编码
let gnacs = create_gnacs(
1, // 资产类别: 实物资产
100, // 子类别: 房地产
156, // 司法辖区: 中国
1 // 合规状态: 已验证
);
// 解析GNACS编码
let info = parse_gnacs(gnacs);
```
#### 使用安全数学运算
```charter
use charter_std::utils::math::{safe_add, safe_mul, percentage};
let a = 100u256;
let b = 200u256;
// 安全加法（防溢出）
let sum = safe_add(a, b);
// 计算百分比
let result = percentage(1000, 15); // 1000的15% = 150
```
