# AGPL Violation Evidence Report: ChainOpera Plagiarized NOFX
**Report Date**: December 20, 2025
**Reporting Party**: NOFX Open Source Community
**Project URL**: https://github.com/NoFxAiOS/nofx
**Accused Party**: ChainOpera (COAI)
**License Involved**: GNU Affero General Public License v3.0 (AGPL-3.0)
---
## 1. Executive Summary
ChainOpera used the `equity-history-batch` API interface design from the NOFX project, which is protected under AGPL-3.0, on their website `trading-test.chainopera.ai`, but refused to release their source code, violating the AGPL-3.0 license terms.
ChainOpera claims the interface was "rewritten in Python." This report will prove from both legal and technical perspectives that: **even a rewrite still constitutes an AGPL violation**.

## 3. Technical Evidence: Code Comparison
### 3.1 API Path Comparison
| Project | API Path | HTTP Method |
|---------|----------|-------------|
| **NOFX** | `/api/equity-history-batch` | POST |
| **ChainOpera** | `/api/equity-history-batch` | POST |
**Similarity: 100%**
### 3.2 Response Structure Comparison
**NOFX Original Code** (`api/server.go` lines 2725-2729):
```go
result["histories"] = histories
result["count"] = len(histories)
if len(errors) > 0 {
result["errors"] = errors
}
```
**ChainOpera Actual Response** (from network request screenshot):
```json
{
"histories": {...},
"errors": {},
"count": 1
}
```
**Comparison Results**:
| Field | NOFX | ChainOpera | Similarity |
|-------|------|------------|------------|
| `histories` | ✓ | ✓ | 100% |
| `errors` | ✓ | ✓ | 100% |
| `count` | ✓ | ✓ | 100% |
### 3.3 History Data Fields Comparison
**NOFX Original Code** (`api/server.go` lines 2676-2682):
```go
history = append(history, map[string]interface{}{
"timestamp": snap.Timestamp,
"total_equity": snap.TotalEquity,
"total_pnl": snap.UnrealizedPnL,
"total_pnl_pct": pnlPct,
"balance": snap.Balance,
})
```
**ChainOpera Actual Response**:
```json
{
"timestamp": "2025-12-15T11:21:05.432240",
"balance": 227.30274403,
"equity": 227.30274403,
"total_pnl": 0
}
```
**Comparison Results**:
| NOFX Field | ChainOpera Field | Similarity |
|------------|------------------|------------|
| `timestamp` | `timestamp` | 100% |
| `balance` | `balance` | 100% |
| `total_equity` | `equity` | Semantically identical |
| `total_pnl` | `total_pnl` | 100% |
### 3.4 Originality Evidence
`equity-history-batch` is an **original design** by NOFX:
1. **Interface Naming**: `equity-history-batch` is a self-created compound term, not an industry standard
2. **Batch Query Design**: Supporting multiple trader_id queries simultaneously is a unique design for performance optimization
3. **Response Structure**: The `{histories, errors, count}` triplet is an original design
4. **Time Filtering**: The `hours` parameter design is an original feature
---
## 4. Legal Rebuttal to the "Python Rewrite" Defense
### 4.1 AGPL-3.0 Definition of "Modify"
**AGPL-3.0 Section 0**:
> "To 'modify' a work means to copy from or adapt all or part of the work in a fashion requiring copyright permission, other than the making of an exact copy."
**Key Point**: Rewriting in another language (Go → Python) constitutes "adaptation" and remains subject to AGPL.
### 4.2 Legal Definition of Derivative Works
**AGPL-3.0 Section 0**:
> A "covered work" means either the unmodified Program or a work based on the Program.
**U.S. Copyright Law 17 U.S.C. § 101**:
> A "derivative work" is a work based upon one or more preexisting works, such as a translation... in which a work may be recast, transformed, or adapted.
**Key Point**: "Translating" Go code to Python code falls under the legal definition of a "derivative work."
### 4.3 Why "Rewriting" Still Constitutes Infringement
| Argument | Legal Analysis |
|----------|----------------|
| "We rewrote it in Python" | Language conversion is "adaptation"; derivative works must comply with the original license |
| "The code is completely different" | Copyright protects **expression**; API design is a form of expression |
| "This is generic functionality" | `equity-history-batch` naming and `{histories, errors, count}` structure are original designs, not generic functionality |
### 4.4 Case Reference
**Oracle v. Google (2021)**:
The U.S. Supreme Court confirmed that API designs are subject to copyright protection. Even though Google reimplemented the Java API, copyright issues still needed to be considered.
**Key Implications**:
- The **Structure, Sequence, and Organization (SSO)** of APIs is protected by copyright
- Even if implemented in a different language, identical API designs may still constitute infringement

## 5. Questions ChainOpera Must Answer
ChainOpera has not responded to the following core questions:
| # | Question | ChainOpera Response |
|---|----------|---------------------|
| 1 | Why is the API path identical to NOFX? | ❌ No response |
| 2 | Why is the response structure `{histories, errors, count}` identical? | ❌ No response |
| 3 | Why are field names `timestamp, balance, total_pnl` identical? | ❌ No response |
| 4 | If independently developed, why is it highly consistent with NOFX? | ❌ No response |
| 5 | Are you willing to release source code per AGPL-3.0? | ❌ No response |
---
## 6. Git Evidence Verification Method
Anyone can verify the authenticity of the evidence with the following commands:
```bash
# Clone the repository
git clone https://github.com/NoFxAiOS/nofx.git
cd nofx
# Verify AGPL license effective date
git show e88f84215831d1682e05141eb0c27216dcbd6d47 --format="%H %ai %s" --no-patch
# Output: e88f8421... 2025-11-03 19:50:50 +0800 Upgrade this repository's open-source license to AGPL.
# Verify equity-history-batch interface creation date
git show 5af5c0b51773737f166eacea646e3960cee29f59 --format="%H %ai %s" --no-patch
# Output: 5af5c0b5... 2025-11-03 20:14:39 +0800 Enhance leaderboard and security for trader management
# View interface implementation code
git show 5af5c0b51773737f166eacea646e3960cee29f59:api/server.go | grep -A 50 "handleEquityHistoryBatch"
```

## 7. Legal Basis Summary
### 7.1 Key AGPL-3.0 Provisions
**Section 13 - Remote Network Interaction**:
> Notwithstanding any other provision of this License, if you modify the Program, your modified version must prominently offer all users interacting with it remotely through a computer network... an opportunity to receive the Corresponding Source of your version.
### 7.2 ChainOpera's Violations
| Violation | Description |
|-----------|-------------|
| Using AGPL code | Used NOFX's API design |
| Providing network service | Operating publicly at `trading-test.chainopera.ai` |
| Not releasing source code | No source code access provided |
| Not declaring license | Did not declare use of AGPL code |
---
## 8. Evidence List
| # | Evidence Type | Description | Preservation Method |
|---|---------------|-------------|---------------------|
| 1 | Git Commit | AGPL license effective record | SHA-1: `e88f8421...` |
| 2 | Git Commit | equity-history-batch creation record | SHA-1: `5af5c0b5...` |
| 3 | Source Code | api/server.go lines 2542-2732 | Git repository |
| 4 | Website Screenshot | ChainOpera API response | Blockchain timestamping recommended |
| 5 | Network Request | trading-test.chainopera.ai request logs | Notarization recommended |
---
## 9. Conclusions
1. **Timeline evidence is conclusive**: The `equity-history-batch` interface was created 24 minutes after AGPL took effect; it has been protected since inception.
2. **Technical evidence is sufficient**: API path, response structure, and field naming are highly consistent, beyond reasonable coincidence.
3. **"Python rewrite" defense is invalid**:
- Language conversion constitutes "adaptation"; derivative works must comply with AGPL
- API design itself is protected by copyright
- Identical structure, sequence, and organization proves copying, not independent development
4. **ChainOpera must either**:
- Release their complete source code in compliance with AGPL-3.0; OR
- Cease using the related functionality and take down the service

```
---
## 三、技术证据：代码对比
### 3.1 API 路径对比
| 项目 | API 路径 | HTTP 方法 |
|------|----------|-----------|
| **NOFX** | `/api/equity-history-batch` | POST |
| **ChainOpera** | `/api/equity-history-batch` | POST |
**相似度：100%**
### 3.2 响应结构对比
**NOFX 原始代码** (`api/server.go` 第 2725-2729 行)：
```go
result["histories"] = histories
result["count"] = len(histories)
if len(errors) > 0 {
result["errors"] = errors
}
```
**ChainOpera 实际返回**（网络请求截图）：
```json
{
"histories": {...},
"errors": {},
"count": 1
}
```
**对比结果**：
| 字段 | NOFX | ChainOpera | 相似度 |
|------|-----------|------------|--------|
| `histories` | ✓ | ✓ | 100% |
| `errors` | ✓ | ✓ | 100% |
| `count` | ✓ | ✓ | 100% |
### 3.3 历史数据字段对比
**NOFX 原始代码** (`api/server.go` 第 2676-2682 行)：
```go
history = append(history, map[string]interface{}{
"timestamp": snap.Timestamp,
"total_equity": snap.TotalEquity,
"total_pnl": snap.UnrealizedPnL,
"total_pnl_pct": pnlPct,
"balance": snap.Balance,
})
```
**ChainOpera 实际返回**：
```json
{
"timestamp": "2025-12-15T11:21:05.432240",
"balance": 227.30274403,
"equity": 227.30274403,
"total_pnl": 0
}
```
**对比结果**：
| NOFX 字段 | ChainOpera 字段 | 相似度 |
|----------------|-----------------|--------|
| `timestamp` | `timestamp` | 100% |
| `balance` | `balance` | 100% |
| `total_equity` | `equity` | 语义相同 |
| `total_pnl` | `total_pnl` | 100% |
### 3.4 独创性证据
`equity-history-batch` 是 NOFX 的**原创设计**：
1. **接口命名**：`equity-history-batch` 是自创的复合词，不是行业标准术语
2. **批量查询设计**：支持多个 trader_id 同时查询，是针对性能优化的独特设计
3. **响应结构**：`{histories, errors, count}` 三元组是原创设计
4. **时间过滤**：`hours` 参数设计是原创功能
---
## 四、"Python 重写"狡辩的法律反驳
### 4.1 AGPL-3.0 对"修改"的定义
**AGPL-3.0 第 0 条**：
> "To 'modify' a work means to copy from or adapt all or part of the work in a fashion requiring copyright permission, other than the making of an exact copy."
>
> "修改"作品是指以需要版权许可的方式复制或改编全部或部分作品，而不是制作精确副本。
**关键点**：用另一种语言重写（Go → Python）属于"改编"(adapt)，仍受 AGPL 约束。
### 4.2 派生作品的法律定义
**AGPL-3.0 第 0 条**：
> A "covered work" means either the unmodified Program or a work based on the Program.
>
> "受保护作品"是指未修改的程序或基于程序的作品。
**美国版权法 17 U.S.C. § 101**：
> A "derivative work" is a work based upon one or more preexisting works, such as a translation... in which a work may be recast, transformed, or adapted.
>
> "派生作品"是基于一个或多个既有作品的作品，例如翻译...其中作品可能被重铸、转换或改编。
**关键点**：将 Go 代码"翻译"为 Python 代码，属于法律定义的"派生作品"。
### 4.3 为什么"重写"仍然构成侵权
| 论点 | 法律分析 |
|------|----------|
| "我们用 Python 重写了" | 语言转换属于"改编"，派生作品仍需遵守原许可证 |
| "代码完全不同" | 版权保护的是**表达**，API 设计是一种表达形式 |
| "这是通用功能" | `equity-history-batch` 命名和 `{histories, errors, count}` 结构是独创设计，不是通用功能 |
### 4.4 类案参考
**Oracle v. Google (2021)**：
美国最高法院确认 API 设计受版权保护，即使谷歌重新实现了 Java API，仍需考虑版权问题。
**关键启示**：
- API 的**结构、顺序和组织** (Structure, Sequence, and Organization, SSO) 受版权保护
- 即使用不同语言实现，如果 API 设计相同，仍可能构成侵权
