## 🐛 发现的问题
### 问题1: 缺少证券特有功能
**严重程度**: ⚠️ 高
**描述**: ACC-1400应该有证券特有的功能，但目前只是ACC-1410的简单包装
**缺失功能**:
1. ❌ 股息分配
2. ❌ 投票权管理
3. ❌ 转让限制（白名单/黑名单）
4. ❌ 合规检查
5. ❌ 强制赎回
6. ❌ 证券信息查询
**建议**: 添加证券特有功能
```rust
impl Acc1400 {
/// 分配股息
pub fn distribute_dividend(
&mut self,
partition_id: &[u8; 32],
dividend_per_share: u64,
) -> Result<()> {
// 实现股息分配逻辑
}
/// 投票
pub fn vote(
&mut self,
partition_id: &[u8; 32],
voter: &str,
proposal_id: &str,
vote: bool,
) -> Result<()> {
// 实现投票逻辑
}
/// 检查转让合规性
pub fn check_transfer_compliance(
&self,
from: &str,
to: &str,
amount: u64,
partition_id: &[u8; 32],
) -> Result<bool> {
// 实现合规检查
}
/// 强制赎回
pub fn force_redeem(
&mut self,
partition_id: &[u8; 32],
account: &str,
amount: u64,
) -> Result<()> {
// 实现强制赎回
}
}
```
**状态**: ❌ 待实现
---
### 问题2: 缺少证券元数据
**严重程度**: ⚠️ 中等
**描述**: 没有存储证券的详细信息
**建议**: 添加证券元数据
```rust
#[derive(Debug, Clone, Serialize, Deserialize)]
pub struct SecurityMetadata {
pub name: String,
pub symbol: String,
pub issuer: String,
pub issue_date: DateTime<Utc>,
pub maturity_date: Option<DateTime<Utc>>,
pub total_supply: u64,
pub par_value: u64,
pub dividend_rate: Option<f64>,
pub voting_rights: bool,
pub transferable: bool,
pub regulatory_info: RegulatoryInfo,
}
impl Acc1400 {
pub fn set_security_metadata(
&mut self,
partition_id: &[u8; 32],
metadata: SecurityMetadata,
) -> Result<()> {
// 实现元数据设置
}
pub fn get_security_metadata(
&self,
partition_id: &[u8; 32],
) -> Result<SecurityMetadata> {
// 实现元数据查询
}
}
```
**状态**: ❌ 待实现
---
### 问题3: 缺少转让限制
**严重程度**: ⚠️ 高
**描述**: 证券转让应该有限制（如白名单、黑名单、锁定期等）
**建议**: 添加转让限制
```rust
#[derive(Debug, Clone)]
pub struct TransferRestriction {
pub whitelist: HashSet<String>,
pub blacklist: HashSet<String>,
pub min_holding_period: Duration,
pub max_holders: Option<usize>,
}
impl Acc1400 {
pub fn set_transfer_restriction(
&mut self,
partition_id: &[u8; 32],
restriction: TransferRestriction,
) -> Result<()> {
// 实现转让限制设置
}
pub fn check_transfer_allowed(
&self,
from: &str,
to: &str,
partition_id: &[u8; 32],
) -> Result<bool> {
// 检查是否允许转让
}
}
```
**状态**: ❌ 待实现
---
### 问题4: 缺少事件通知
**严重程度**: ⚠️ 中等
**描述**: 没有事件通知机制
**建议**: 添加事件
```rust
#[derive(Debug, Clone, Serialize, Deserialize)]
pub enum SecurityEvent {
Issued {
partition_id: [u8; 32],
to: String,
amount: u64,
},
Transferred {
partition_id: [u8; 32],
from: String,
to: String,
amount: u64,
},
DividendDistributed {
partition_id: [u8; 32],
dividend_per_share: u64,
},
Voted {
partition_id: [u8; 32],
voter: String,
proposal_id: String,
},
}
impl Acc1400 {
pub fn emit_event(&self, event: SecurityEvent) {
// 发送事件
}
}
```
**状态**: ❌ 待实现
---
### 问题5: 缺少监管报告
**严重程度**: ⚠️ 中等
**描述**: 没有生成监管报告的功能
**建议**: 添加监管报告
```rust
#[derive(Debug, Clone, Serialize, Deserialize)]
pub struct RegulatoryReport {
pub partition_id: [u8; 32],
pub total_holders: usize,
pub total_supply: u64,
pub transfers: Vec<TransferRecord>,
pub dividends: Vec<DividendRecord>,
pub votes: Vec<VoteRecord>,
}
impl Acc1400 {
pub fn generate_regulatory_report(
&self,
partition_id: &[u8; 32],
start_time: DateTime<Utc>,
end_time: DateTime<Utc>,
) -> Result<RegulatoryReport> {
// 生成监管报告
}
}
```
**状态**: ❌ 待实现

let future_time = std::time::SystemTime::now()
.duration_since(std::time::UNIX_EPOCH)
.unwrap()
.as_secs() + 3600;
acc1400.lock_security_account("investor1", future_time);
// 提前解锁
acc1400.unlock_security_account("investor1");
```
### 转账控制
