+ font-size: 1.25rem; /* 20px */
+ }
+
+ body {
+ font-size: 0.9375rem; /* 15px */
+ }
+}
+```
+
+---
+
+## 5. 字体使用场景

+
+## Introduction
+
+This guide provides comprehensive security best practices for participating in the RustChain ecosystem. Whether you're running a miner, managing wallets, or operating nodes, following these practices will help protect your assets and contribute to network security.
+
+### Security Principles
+
+- **Defense in Depth**: Multiple layers of security controls
+- **Least Privilege**: Grant only necessary permissions
+- **Zero Trust**: Verify explicitly, never trust implicitly
+- **Fail Secure**: Default to secure states on errors
+
+---
+
+## Miner Security
+
+### Hardware Security
+
+#### Physical Security
+- **Secure Location**: Keep mining hardware in a locked, access-controlled environment
+- **Environmental Controls**: Maintain proper temperature (15-25°C) and humidity (40-60%)
+- **Power Protection**: Use UPS (Uninterruptible Power Supply) to prevent data corruption
+- **Network Isolation**: Consider VLAN segregation for mining equipment
+
+#### Hardware Integrity
+```bash
+# Verify hardware fingerprint hasn't been tampered
+rustchain-miner verify-fingerprint --device /dev/miner0
+
+# Check for unauthorized firmware modifications
+rustchain-miner firmware-check --verbose
+```
+
+### Software Security
+
+#### System Hardening
+```bash
+# Update system packages regularly
+sudo apt update && sudo apt upgrade -y
+
+# Disable unnecessary services
+sudo systemctl disable bluetooth
+sudo systemctl disable cups
+
+# Configure firewall (Linux)
+sudo ufw default deny incoming
+sudo ufw default allow outgoing
+sudo ufw allow from 192.168.1.0/24 to any port 22 # SSH from LAN only
+sudo ufw enable
+```
+
+#### Miner Configuration Security
+```toml
+# rustchain.toml - Secure Configuration Example
+
+[security]
+# Never hardcode credentials - use environment variables
+api_key = "${RUSTCHAIN_API_KEY}"
+wallet_id = "${RUSTCHAIN_WALLET_ID}"
+
+# Enable TLS for all connections
+require_tls = true
+verify_certificates = true
+
+# Rate limiting to prevent abuse
+max_requests_per_minute = 60
+
+[logging]
+# Log security events but redact sensitive data
+level = "info"
+redact_credentials = true
+audit_log_path = "/var/log/rustchain/audit.log"
+```
+
+#### Access Control
+```bash
+# Create dedicated user for miner process
+sudo useradd -r -s /bin/false rustchain-miner
+
+# Set restrictive file permissions
+sudo chown -R rustchain-miner:rustchain-miner /opt/rustchain
+sudo chmod 750 /opt/rustchain
+sudo chmod 640 /opt/rustchain/config/*.toml
+```
+
+### Network Security
+
+#### Firewall Rules
+```bash
+# Essential ports only
+# SSH (22) - Restrict to management network
+# Miner API (8545) - Localhost only
+# RustChain P2P (30333) - As needed
+
+# Example iptables rules
+iptables -A INPUT -p tcp --dport 22 -s 192.168.1.0/24 -j ACCEPT
+iptables -A INPUT -p tcp --dport 8545 -s 127.0.0.1 -j ACCEPT
+iptables -A INPUT -p tcp --dport 30333 -j ACCEPT
+iptables -A INPUT -j DROP
+```
+
+#### TLS/SSL Configuration
+```toml
+[tls]
+enabled = true
+cert_path = "/etc/ssl/certs/rustchain.crt"
+key_path = "/etc/ssl/private/rustchain.key"
+min_version = "TLS1.2"
+cipher_suites = [
+ "TLS_ECDHE_RSA_WITH_AES_256_GCM_SHA384",
+ "TLS_ECDHE_RSA_WITH_AES_128_GCM_SHA256"
+]
+```
+
+### Monitoring & Alerting
+
+```bash
+# Monitor miner health
+rustchain-miner health-check --interval 60
+
+# Set up alerts for anomalies
+# - Hash rate drops > 20%
+# - Temperature > 80°C
+# - Unauthorized access attempts
+# - Configuration changes
+```
+
+---
+
+## Wallet Security
+
+### Wallet Types & Use Cases
+
+| Wallet Type | Security Level | Best For | Risk |
+|-------------|---------------|----------|------|
+| Hardware Wallet | ⭐⭐⭐⭐⭐ | Long-term storage, large amounts | Physical loss |
+| Desktop Wallet | ⭐⭐⭐ | Daily operations, medium amounts | Malware, OS compromise |
+| Mobile Wallet | ⭐⭐ | Small amounts, payments | Device loss, apps |
+| Web Wallet | ⭐ | Testing, minimal funds | Phishing, server breach |
+
+### Private Key Management
+
+#### Golden Rules
+1. **NEVER** share your private key or seed phrase
+2. **NEVER** store keys in plain text
+3. **NEVER** commit keys to version control
+4. **ALWAYS** use encrypted storage
+5. **ALWAYS** backup securely (offline, multiple locations)
+
+#### Secure Storage Methods
+
+**Hardware Wallet (Recommended)**
+```bash
+# Using Ledger or Trezor
+# Keys never leave the device
+# Transactions signed on-device
+
+rustchain-wallet connect --hardware ledger
+rustchain-wallet sign --tx transaction.json --hardware
+```
+
+**Encrypted Software Wallet**
+```bash
+# Create encrypted wallet
+rustchain-wallet create --encrypted --cipher aes-256-gcm
+
+# Set strong passphrase (minimum 16 characters)
+# Use combination of: uppercase, lowercase, numbers, symbols
+
+# Backup encrypted wallet file
+cp ~/.rustchain/wallet.dat /secure/backup/location/
+```
+
+### Multi-Signature Wallets
+
+For enhanced security, use multi-sig wallets for significant amounts:
+
+```toml
+# Multi-sig configuration (2-of-3 example)
+[multisig]
+type = "2-of-3"
+signers = [
+ "0x1234...abcd", # Primary key (desktop)
+ "0x5678...efgh", # Backup key (hardware wallet)
+ "0x9abc...ijkl" # Recovery key (offline storage)
+]
+threshold = 2
+```
+
+### Transaction Security
+
+#### Before Sending
+```bash
+# Verify recipient address
+rustchain-wallet verify-address 0xRecipient...
+
+# Check transaction details
+rustchain-wallet decode-tx transaction.json
+
+# Use address whitelist for frequent recipients
+rustchain-wallet whitelist add 0xTrusted... --label "Exchange"
+```
+
+#### Safe Transaction Practices
+- Double-check recipient addresses (first 4 and last 4 characters)
+- Start with small test transactions for new addresses
+- Enable transaction notifications
+- Set daily withdrawal limits
+- Use time-locks for large transfers
+
+### Backup & Recovery
+
+#### Backup Strategy (3-2-1 Rule)
+- **3** copies of your wallet backup
+- **2** different storage media (USB drive + paper)
+- **1** copy stored offsite (safe deposit box, trusted family)
+
+#### Backup Commands
+```bash
+# Create encrypted backup
+rustchain-wallet backup --output backup.enc --encrypt
+
+# Verify backup integrity
+rustchain-wallet verify-backup backup.enc
+
+# Test recovery (on separate device)
+rustchain-wallet restore --from backup.enc
+```
+
+---
+
+## Node Operator Security
+
+### System Requirements & Hardening
+
+#### OS Security Baseline
+```bash
+# Use LTS versions only (Ubuntu 22.04 LTS, RHEL 9)
+# Enable automatic security updates
+sudo apt install unattended-upgrades
+sudo dpkg-reconfigure --priority=low unattended-upgrades
+
+# Kernel hardening parameters
+cat >> /etc/sysctl.d/99-rustchain.conf << EOF
+net.ipv4.tcp_syncookies = 1
+net.ipv4.conf.all.accept_redirects = 0
+net.ipv4.conf.all.send_redirects = 0
+net.ipv4.conf.all.accept_source_route = 0
+kernel.kptr_restrict = 2
+kernel.dmesg_restrict = 1
+EOF
+
+sysctl --system
+```
+
+#### Container Security (Docker)
+```yaml
+# docker-compose.yml - Secure Configuration
+version: '3.8'
+services:
+ rustchain-node:
+ image: rustchain/node:latest
+ security_opt:
+ - no-new-privileges:true
+ read_only: true
+ tmpfs:
+ - /tmp
+ cap_drop:
+ - ALL
+ cap_add:
+ - NET_BIND_SERVICE
+ user: "1000:1000"
+ volumes:
+ - ./data:/data:ro
+ - ./config:/config:ro
+ networks:
+ - rustchain-internal
+
+networks:
+ rustchain-internal:
+ driver: bridge
+ internal: true
+```
+
+### Consensus Security
+
+#### Validator Key Protection
+```bash
+# Store validator keys in HSM or hardware wallet
+rustchain-validator init --hsm --device /dev/hsm0
+
+# Never expose validator keys to network
+# Use separate signing machine (air-gapped if possible)
+
+# Rotate keys periodically
+rustchain-validator rotate-keys --interval 90d
+```
+
+#### Slashing Prevention
+- Monitor node uptime (maintain > 99%)
+- Set up redundant nodes in different locations
+- Configure alerting for missed attestations
+- Keep adequate collateral buffer
+
+### Network Security
+
+#### DDoS Protection
+```bash
+# Rate limiting with nginx
+limit_req_zone $binary_remote_addr zone=one:10m rate=10r/s;
+
+server {
+ location /api/ {
+ limit_req zone=one burst=20 nodelay;
+ proxy_pass http://rustchain-node:8545;
+ }
+}
+
+# Connection limits
+iptables -A INPUT -p tcp --syn -m connlimit --connlimit-above 20 -j DROP
+```
+
+#### Peer Management
+```toml
+[network]
+# Trusted peers only (optional, for private networks)
+trusted_peers = [
+ "/ip4/192.168.1.100/tcp/30333",
+ "/ip4/192.168.1.101/tcp/30333"
+]
+
+# Maximum peer connections
+max_peers = 50
+
+# Ban misbehaving peers automatically
+ban_misbehaving = true
+ban_duration = "24h"
+```
+
+---
+
+## API & Application Security
+
+### Authentication
+
+#### API Key Management
+```bash
+# Generate strong API key
+rustchain-api key generate --bits 256
+
+# Rotate keys every 90 days
+rustchain-api key rotate --current KEY_ID --expires-in 90d
+
+# Revoke compromised keys immediately
+rustchain-api key revoke KEY_ID --reason "suspected_compromise"
+```
+
+#### OAuth 2.0 Implementation
+```toml
+[oauth]
+client_id = "${OAUTH_CLIENT_ID}"
+client_secret = "${OAUTH_CLIENT_SECRET}"
+redirect_uri = "https://yourapp.com/callback"
+scope = "read write"
+pkce_required = true
+```
+
+### Input Validation
+
+```python
+# Example: Validate wallet address
+import re
+
+def validate_wallet_address(address: str) -> bool:
+ """Validate RustChain wallet address format"""
+ pattern = r'^0x[a-fA-F0-9]{40}$'
+ if not re.match(pattern, address):
+ return False
+
+ # Additional checksum validation
+ return rustchain.verify_checksum(address)
+
+# Sanitize all user inputs
+from html import escape
+
+def sanitize_input(user_input: str) -> str:
+ """Prevent XSS and injection attacks"""
+ return escape(user_input.strip())
+```
+
+### Rate Limiting
+
+```python
+# Implement rate limiting
+from flask_limiter import Limiter
+from flask_limiter.util import get_remote_address
+
+limiter = Limiter(
+ app=app,
+ key_func=get_remote_address,
+ default_limits=["100 per hour", "10 per minute"]
+)
+
+@app.route("/api/transfer", methods=["POST"])
+@limiter.limit("5 per minute")
+def transfer():
+ # Transfer logic
+ pass
+```
+
+### Logging & Monitoring
+
+```toml
+[logging]
+# Structured logging for security events
+format = "json"
+level = "info"
+
+# Redact sensitive fields
+redact_fields = [
+ "api_key",
+ "private_key",
+ "password",
+ "token",
+ "authorization"
+]
+
+# Security event categories
+security_events = [
+ "authentication_failure",
+ "authorization_denied",
+ "configuration_change",
+ "key_rotation",
+ "suspicious_activity"
+]
+```
+
+---
+
+## Operational Security
+
+### Credential Management
+
+#### Environment Variables
+```bash
+# .env file (NEVER commit to git)
+RUSTCHAIN_API_KEY="your-api-key-here"
+RUSTCHAIN_WALLET_ID="your-wallet-id"
+DATABASE_URL="postgresql://user:pass@localhost/db"
+
+# Load securely
+set -a
+source .env
+set +a
+
+# Or use secrets manager
+aws secretsmanager get-secret-value --secret-id rustchain/credentials
+```
+
+#### Password Policy
+- Minimum 16 characters
+- Mix of uppercase, lowercase, numbers, symbols
+- No dictionary words or personal information
+- Unique password for each service
+- Use password manager (1Password, Bitwarden, KeePass)
+
+### Secure Development

+
+## 🔑 核心环境变量
+
+### 必需变量
+
+| 变量名 | 说明 | 示例值 |
+|--------|------|--------|
+| `RUSTCHAIN_WALLET` | 矿工钱包地址 | `my-miner-wallet` |
+| `RUSTCHAIN_NODE_URL` | 节点 API 地址 | `https://rustchain.org` |
+| `RUSTCHAIN_NETWORK` | 网络环境 | `mainnet` / `testnet` |
+
+### 可选变量
+
+| 变量名 | 说明 | 默认值 |
+|--------|------|--------|
+| `RUSTCHAIN_LOG_LEVEL` | 日志级别 | `info` |
+| `RUSTCHAIN_DATA_DIR` | 数据存储目录 | `~/.rustchain` |
+| `RUSTCHAIN_MINER_ID` | 自定义矿工 ID | 自动生成 |
+
+---
+
+## ⚙️ 配置管理
+
+### 方式一：.env 文件（推荐）
+
+创建 `.env` 文件在项目根目录：
+
+```bash
+# .env
+RUSTCHAIN_WALLET=my-miner-wallet
+RUSTCHAIN_NODE_URL=https://rustchain.org
+RUSTCHAIN_NETWORK=mainnet
+RUSTCHAIN_LOG_LEVEL=info
+```
+
+使用 `python-dotenv` 加载：
+
+```python
+from dotenv import load_dotenv
+load_dotenv()
+```
+
+### 方式二：系统环境变量
+
+**Linux/macOS:**
+
+```bash
+# 临时设置（当前终端会话）
+export RUSTCHAIN_WALLET="my-miner-wallet"
+export RUSTCHAIN_NODE_URL="https://rustchain.org"
+
+# 永久设置（添加到 ~/.bashrc 或 ~/.zshrc）
+echo 'export RUSTCHAIN_WALLET="my-miner-wallet"' >> ~/.bashrc
+source ~/.bashrc
+```
+
+**Windows PowerShell:**
+
+```powershell
+# 临时设置
+$env:RUSTCHAIN_WALLET="my-miner-wallet"
+
+# 永久设置（用户级别）
+[System.Environment]::SetEnvironmentVariable('RUSTCHAIN_WALLET', 'my-miner-wallet', 'User')
+```
+
+### 方式三：配置文件
+
+创建 `config.toml` 或 `config.yaml`：
+
+```toml
+# config.toml
+[wallet]
+address = "my-miner-wallet"
+
+[node]
+url = "https://rustchain.org"
+network = "mainnet"
+
+[mining]
+log_level = "info"
+data_dir = "~/.rustchain"
+```
+
+---
+
+## 🔒 安全存储
+
+### 1. 敏感信息加密
+
+**使用 git-crypt:**
+
+```bash
+# 安装
+git-crypt unlock
+
+# 加密 .env 文件
+echo ".env filter=git-crypt diff=git-crypt" >> .gitattributes
+git-crypt lock
+```
+
+**使用 age 加密:**
+
+```bash
+# 生成密钥
+age-keygen -o age-key.txt
+
+# 加密 .env
+age -R age-key.txt -o .env.age .env
+
+# 解密
+age -d -i age-key.txt .env.age
+```
+
+### 2. 密钥管理工具
+
+**1Password CLI:**
+
+```bash
+# 读取密钥
+op read "op://vault/RustChain/credential"
+
+# 注入到环境变量
+export RUSTCHAIN_WALLET=$(op read "op://vault/RustChain/wallet")
+```
+
+**HashiCorp Vault:**
+
+```bash
+# 读取密钥
+vault kv get -field=wallet secret/rustchain
+
+# 动态注入
+export RUSTCHAIN_WALLET=$(vault kv get -field=wallet secret/rustchain)
+```
+
+### 3. .gitignore 配置
+
+```gitignore
+# 环境变量文件
+.env
+.env.local
+.env.*.local
+
+# 密钥文件
+*.pem
+*.key
+age-key.txt
+*.age
+
+# 配置文件（含敏感信息）
+config.local.toml
+secrets.yaml
+```
+
+---
+
+## ✅ 最佳实践
+
+### 1. 环境分离
+
+```bash
+# .env.development
+RUSTCHAIN_NETWORK=testnet
+RUSTCHAIN_LOG_LEVEL=debug
+
+# .env.production
+RUSTCHAIN_NETWORK=mainnet
+RUSTCHAIN_LOG_LEVEL=warn
+```
+
+### 2. 验证脚本
+
+创建 `verify-env.sh`：
+
+```bash
+#!/bin/bash
+
+echo "🔍 验证 RustChain 环境变量..."
+
+# 检查必需变量
+required_vars=("RUSTCHAIN_WALLET" "RUSTCHAIN_NODE_URL")
+
+for var in "${required_vars[@]}"; do
+ if [ -z "${!var}" ]; then
+ echo "❌ 错误：$var 未设置"
+ exit 1
+ fi
+ echo "✅ $var 已设置"
+done
+
+# 验证节点连接
+echo "🔗 测试节点连接..."
+curl -sk "${RUSTCHAIN_NODE_URL}/health" > /dev/null
+if [ $? -eq 0 ]; then
+ echo "✅ 节点连接正常"
+else
+ echo "❌ 节点连接失败"
+ exit 1
+fi
+
+echo "✅ 所有检查通过"
+```
+
+### 3. Docker 环境变量
+
+```dockerfile
+# Dockerfile
+FROM python:3.10-slim
+
+# 使用 ARG 构建时变量
+ARG RUSTCHAIN_WALLET
+ENV RUSTCHAIN_WALLET=${RUSTCHAIN_WALLET}
+
+# 或使用 --env-file
+# docker run --env-file .env rustchain-miner
+```
+
+```yaml
+# docker-compose.yml
+version: '3.8'
+services:
+ miner:
+ image: rustchain-miner
+ env_file:
+ - .env
+ environment:
+ - RUSTCHAIN_LOG_LEVEL=info
+```
+
+### 4. 轮换策略
+
+```bash
+# 定期轮换密钥脚本
+#!/bin/bash
+# rotate-secrets.sh
+
+echo "🔄 开始轮换密钥..."
+
+# 备份旧配置
+cp .env .env.backup.$(date +%Y%m%d)
+
+# 生成新密钥（示例）
+# op item update "RustChain" credential=$(openssl rand -hex 32)
+
+# 重启服务
+systemctl --user restart rustchain-miner
+
+echo "✅ 密钥轮换完成"
+```
+
+---
+
+## 🐛 故障排查
+
+### 常见问题
+
+| 问题 | 解决方案 |
+|------|----------|
+| 变量未找到 | 检查 `.env` 文件路径，确认 `load_dotenv()` 调用 |
+| 节点连接失败 | 验证 `RUSTCHAIN_NODE_URL` 是否正确，检查防火墙 |
+| 钱包余额为 0 | 确认 `RUSTCHAIN_WALLET` 名称正确，检查是否已创建 |
+| HTTPS 证书错误 | 使用 `-sk` 标志（自签名证书），或更新 CA 证书 |
+
+### 调试命令
+
+```bash
+# 查看所有 RustChain 相关变量
+env | grep RUSTCHAIN
+
+# 测试钱包余额
+curl -sk "https://rustchain.org/wallet/balance?miner_id=$RUSTCHAIN_WALLET"
+
+# 检查节点健康
+curl -sk https://rustchain.org/health

+# RustChain Network Topology
+
+## Overview
+
+RustChain operates a decentralized Proof-of-Antiquity blockchain network with a lightweight, accessible architecture designed to support vintage hardware participation.
+

+
+## Node Architecture
+
+### Active Nodes (3)
+
+| Node | IP Address | Role | Status | Location |
+|------|------------|------|--------|----------|
+| **Node 1** | 50.28.86.131 | Primary + Explorer + API | ✅ Active | US |
+| **Node 2** | 50.28.86.153 | Ergo Anchor + Backup | ✅ Active | US |
+| **Node 3** | 76.8.228.245 | External (Community) | ✅ Active | US |
+
+### Node Responsibilities
+
+#### Node 1 (Primary)
+- **Explorer UI**: Serves the block explorer at `/explorer`
+- **API Gateway**: Handles all REST API requests
+- **Wallet Services**: Manages wallet balance queries and transactions
+- **Governance UI**: Hosts governance proposal interface
+- **Health Monitoring**: Provides network health endpoints
+
+#### Node 2 (Ergo Anchor)
+- **Blockchain Anchoring**: Periodically commits RustChain state to Ergo blockchain
+- **Backup Node**: Maintains full chain state replica
+- **R4 Register**: Stores commitment hashes in Ergo's R4 register
+- **Immutability Layer**: Provides cryptographic proof of chain state
+
+#### Node 3 (Community Node)
+- **Decentralization**: Independent node operated by community member
+- **Redundancy**: Provides additional network resilience
+- **P2P Sync**: Participates in consensus and block propagation
+
+## Network Layers
+
+### Layer 1: Consensus Layer (Proof-of-Antiquity)
+
+```
+┌─────────────────────────────────────────────────────────────┐
+│ Proof-of-Antiquity Consensus │
+├─────────────────────────────────────────────────────────────┤
+│ 1. Hardware Fingerprinting (RIP-PoA) │
+│ - Clock-skew & oscillator drift │
+│ - Cache timing fingerprint │
+│ - SIMD unit identity (AltiVec/SSE/NEON) │
+│ - Thermal drift entropy │
+│ - Instruction path jitter │
+│ - Anti-emulation checks │
+│ │
+│ 2. Round-Robin Voting (RIP-200) │
+│ - 1 CPU = 1 vote (regardless of speed) │
+│ - Equal reward split × antiquity multiplier │
+│ - No advantage from multiple threads │
+│ │
+│ 3. Epoch-Based Rewards │
+│ - Epoch duration: 10 minutes (600 seconds) │
+│ - Base reward pool: 1.5 RTC per epoch │
+│ - Distribution: Equal split × antiquity multiplier │
+└─────────────────────────────────────────────────────────────┘
+```
+
+### Layer 2: P2P Network Layer
+
+**Connection Type**: Peer-to-Peer mesh network
+
+**Protocol**: HTTP/HTTPS with Ed25519 signature verification
+
+**Node Communication**:
+- Block propagation via P2P sync
+- State reconciliation every epoch
+- Health checks and heartbeat monitoring
+
+**Miner-to-Node Communication**:
+```
+Miner → Node (HTTPS POST)
+ ├─ Hardware fingerprint submission
+ ├─ Attestation proof
+ └─ Reward claim request
+
+Node → Miner (HTTPS Response)
+ ├─ Validation result
+ ├─ Reward calculation
+ └─ Next epoch info
+```
+
+### Layer 3: Application Layer
+
+**API Endpoints** (served by Node 1):
+```bash
+# Network Health
+GET /health
+
+# Current Epoch
+GET /epoch
+
+# Active Miners List
+GET /api/miners
+
+# Wallet Services
+GET /wallet/balance?miner_id=
+POST /wallet/create
+
+# Governance
+GET /governance/proposals
+POST /governance/propose
+POST /governance/vote
+GET /governance/ui
+
+# Block Explorer
+GET /explorer (Web UI)
+```
+
+### Layer 4: Blockchain Anchoring Layer
+
+**Ergo Integration**:
+```
+RustChain Epoch → Commitment Hash → Ergo Transaction (R4 register)
+```
+
+**Process**:
+1. Every N epochs, Node 2 calculates state commitment hash
+2. Hash is embedded in Ergo transaction's R4 register
+3. Transaction ID provides cryptographic proof of existence
+4. Immutable timestamp from Ergo blockchain
+
+**Benefits**:
+- Tamper-proof state verification
+- Independent blockchain validation
+- Long-term archival of chain state
+
+## Connection Topology
+
+### Physical Connections
+
+```
+ Internet
+ │
+ ┌─────────────┼─────────────┐
+ │ │ │
+ ┌────▼────┐ ┌────▼────┐ ┌────▼────┐
+ │ Node 1 │ │ Node 2 │ │ Node 3 │
+ │ :443 │ │ :443 │ │ :443 │
+ └────┬────┘ └────┬────┘ └────┬────┘
+ │ │ │
+ └─────────────┼─────────────┘
+ │
+ ┌─────────────┼─────────────┐
+ │ │ │
+ ┌────▼────┐ ┌────▼────┐ ┌────▼────┐
+ │ Miner 1 │ │ Miner 2 │ │ Miner N │
+ │ (G4) │ │ (G5) │ │ (x86) │
+ └─────────┘ └─────────┘ └─────────┘
+```
+
+### Logical Connections
+
+**Miner → Node**:
+- Protocol: HTTPS (TLS 1.3)
+- Authentication: Ed25519 signed requests
+- Port: 443
+- State: Stateless HTTP requests
+
+**Node ↔ Node**:
+- Protocol: P2P sync over HTTPS
+- Frequency: Every epoch (10 minutes)
+- Data: Block state, miner attestations, governance votes
+- Consensus: Round-robin with hardware-weighted voting
+
+## Network Security
+
+### Anti-Sybil Mechanisms
+
+1. **Hardware Fingerprinting**: Each unique hardware device gets one identity
+2. **Hardware Binding**: Fingerprint bound to single wallet address
+3. **Anti-VM Detection**: VMs receive 1 billionth normal rewards
+4. **Ed25519 Signatures**: All transactions cryptographically signed
+
+### Network Hardening
+
+- **Self-Signed SSL**: Nodes use self-signed certificates (-sk flag required for curl)
+- **Rate Limiting**: API endpoints implement request throttling
+- **Signature Verification**: All wallet operations require valid signatures
+- **Hardware Attestation**: miners must prove real hardware every epoch
+
+## Scalability Considerations
+
+### Current Capacity
+- **Active Nodes**: 3
+- **Supported Miners**: Unlimited (theoretically)
+- **Epoch Duration**: 10 minutes
+- **Transactions per Epoch**: Limited by node capacity
+
+### Future Scaling Plans
+
+1. **Additional Community Nodes**: Decentralize beyond 3 nodes
+2. **Sharded Attestation**: Parallel hardware verification
+3. **Layer-2 Solutions**: State channels for micro-transactions
+4. **Cross-Chain Bridges**: EVM compatibility via FlameBridge
+
+## Monitoring & Observability
+
+### Health Endpoints
+
+```bash
+# Node Health Check
+curl -sk https://rustchain.org/health
+
+# Active Miners Count
+curl -sk https://rustchain.org/api/miners
+
+# Current Epoch Status
+curl -sk https://rustchain.org/epoch
+
+# Block Explorer
+https://rustchain.org/explorer
+```
+
+### Metrics Tracked
+
+- Active miner count
+- Epoch progression
+- Reward distribution
+- Hardware diversity (antiquity multipliers)
+- Node synchronization status
+
+## Disaster Recovery
+
+### Node Failure Scenarios
+
+| Scenario | Impact | Recovery |
+|----------|--------|----------|
+| Node 1 down | API/Explorer unavailable | Node 2 can take over |
+| Node 2 down | Ergo anchoring paused | Resume when restored |
+| Node 3 down | Minimal (community node) | No action needed |
+| 2+ nodes down | Consensus at risk | Emergency protocol |
+
+### Backup Strategy
+
+- **Full State Replication**: All nodes maintain complete chain state
+- **Ergo Anchors**: Periodic immutable backups on Ergo blockchain
+- **Miner Data**: Wallet balances stored in SQLite with replication
+
+## Network Parameters
+
+| Parameter | Value | Description |
+|-----------|-------|-------------|
+| Epoch Duration | 600 seconds | Time between blocks |
+| Base Reward | 1.5 RTC | Per epoch reward pool |
+| Min Multiplier | 1.0× | Modern hardware |
+| Max Multiplier | 2.5× | PowerPC G4 |
+| Multiplier Decay | 15%/year | Prevents permanent advantage |
+| Vote Weight | 1 CPU = 1 vote | Round-robin consensus |
+| Signature Algorithm | Ed25519 | Cryptographic signing |
+
+## Geographic Distribution
+
+```
+United States (3 nodes)
+├── Node 1: 50.28.86.131 (Primary)
+├── Node 2: 50.28.86.153 (Ergo Anchor)
+└── Node 3: 76.8.228.245 (Community)
+```
+
+**Future Goals**: Expand to EU, Asia, and other regions for better decentralization and latency.

+
+## 备份什么
+
+RustChain 的关键数据存储在以下位置：
+
+### 1. 矿工数据目录
+```
+~/.rustchain/
+├── rustchain_miner.py # 矿工程序
+├── fingerprint_checks.py # 硬件指纹检查
+├── venv/ # Python 虚拟环境
+├── start.sh # 启动脚本
+└── miner.log # 矿工日志（运行后生成）
+```
+
+### 2. 系统服务配置
+
+**Linux (systemd):**
+```
+~/.config/systemd/user/rustchain-miner.service
+```
+
+**macOS (launchd):**
+```
+~/Library/LaunchAgents/com.rustchain.miner.plist
+```
+
+### 3. 钱包/矿工 ID
+
+钱包名称（miner_id）在安装时设置，用于：
+- 接收挖矿奖励
+- 身份验证
+- 余额查询
+
+**重要：** 钱包名称是您在安装时指定的字符串（例如：`my-miner-wallet` 或 `miner-desktop-1234`）。
+
+---
+
+## 备份流程
+
+### 步骤 1：停止矿工服务
+
+在备份之前，先停止正在运行的矿工服务。
+
+**Linux:**
+```bash
+systemctl --user stop rustchain-miner
+```
+
+**macOS:**
+```bash
+launchctl stop com.rustchain.miner
+```
+
+### 步骤 2：备份矿工数据目录
+
+```bash
+# 创建备份目录
+mkdir -p ~/rustchain-backup/$(date +%Y%m%d)
+
+# 备份整个 .rustchain 目录
+cp -r ~/.rustchain ~/rustchain-backup/$(date +%Y%m%d)/rustchain-data
+```
+
+### 步骤 3：备份服务配置
+
+**Linux:**
+```bash
+cp ~/.config/systemd/user/rustchain-miner.service \
+ ~/rustchain-backup/$(date +%Y%m%d)/
+```
+
+**macOS:**
+```bash
+cp ~/Library/LaunchAgents/com.rustchain.miner.plist \
+ ~/rustchain-backup/$(date +%Y%m%d)/
+```
+
+### 步骤 4：记录钱包信息
+
+```bash
+# 记录钱包名称（替换为您的实际钱包名）
+echo "your-wallet-name" > ~/rustchain-backup/$(date +%Y%m%d)/wallet-name.txt
+
+# 可选：查询并保存当前余额
+curl -sk "https://rustchain.org/wallet/balance?miner_id=your-wallet-name" \
+ > ~/rustchain-backup/$(date +%Y%m%d)/wallet-balance.json
+```
+
+### 步骤 5：验证备份
+
+```bash
+# 检查备份文件是否存在
+ls -la ~/rustchain-backup/$(date +%Y%m%d)/
+
+# 验证备份大小（应该大于 10MB，包含 venv）
+du -sh ~/rustchain-backup/$(date +%Y%m%d)/rustchain-data
+```
+
+### 步骤 6：重新启动矿工服务
+
+**Linux:**
+```bash
+systemctl --user start rustchain-miner
+systemctl --user status rustchain-miner
+```
+
+**macOS:**
+```bash
+launchctl start com.rustchain.miner
+launchctl list | grep rustchain
+```
+
+---
+
+## 恢复流程
+
+### 场景 1：同一台机器恢复
+
+#### 步骤 1：停止现有服务（如果运行中）
+
+```bash
+# Linux
+systemctl --user stop rustchain-miner
+
+# macOS
+launchctl stop com.rustchain.miner
+```
+
+#### 步骤 2：恢复矿工数据
+
+```bash
+# 备份当前数据（以防万一）
+mv ~/.rustchain ~/.rustchain.old.$(date +%s) 2>/dev/null || true
+
+# 恢复备份
+cp -r ~/rustchain-backup/20260312/rustchain-data ~/.rustchain
+```
+
+#### 步骤 3：恢复服务配置
+
+**Linux:**
+```bash
+mkdir -p ~/.config/systemd/user/
+cp ~/rustchain-backup/20260312/rustchain-miner.service \
+ ~/.config/systemd/user/
+systemctl --user daemon-reload
+systemctl --user enable rustchain-miner
+```
+
+**macOS:**
+```bash
+mkdir -p ~/Library/LaunchAgents/
+cp ~/rustchain-backup/20260312/com.rustchain.miner.plist \
+ ~/Library/LaunchAgents/
+launchctl load ~/Library/LaunchAgents/com.rustchain.miner.plist
+```
+
+#### 步骤 4：启动服务并验证
+
+```bash
+# Linux
+systemctl --user start rustchain-miner
+systemctl --user status rustchain-miner
+journalctl --user -u rustchain-miner -f
+
+# macOS
+launchctl start com.rustchain.miner
+launchctl list | grep rustchain
+tail -f ~/.rustchain/miner.log
+```
+
+#### 步骤 5：验证矿工状态
+
+```bash
+# 检查节点健康
+curl -sk https://rustchain.org/health | jq .
+
+# 检查矿工是否在线
+curl -sk https://rustchain.org/api/miners | jq .
+
+# 查询钱包余额
+curl -sk "https://rustchain.org/wallet/balance?miner_id=your-wallet-name" | jq .
+```
+
+---
+
+### 场景 2：迁移到新机器
+
+#### 在新机器上：
+
+#### 步骤 1：安装基础依赖
+
+```bash
+# 确保 Python 3.8+ 已安装
+python3 --version
+
+# 安装必要工具
+# Ubuntu/Debian
+sudo apt-get update && sudo apt-get install -y python3 python3-venv curl
+
+# macOS (需要 Homebrew)
+brew install python3 curl
+```
+
+#### 步骤 2：传输备份文件
+
+```bash
+# 使用 scp、rsync 或 USB 驱动器传输
+# 示例：使用 scp
+scp -r ~/rustchain-backup/20260312 user@new-machine:~/rustchain-backup/
+```
+
+#### 步骤 3：恢复数据
+
+```bash
+# 创建目录结构
+mkdir -p ~/.rustchain
+mkdir -p ~/.config/systemd/user/ # Linux
+# 或
+mkdir -p ~/Library/LaunchAgents/ # macOS
+
+# 恢复矿工数据
+cp -r ~/rustchain-backup/20260312/rustchain-data/* ~/.rustchain/
+
+# 恢复服务配置（根据平台选择）
+# Linux
+cp ~/rustchain-backup/20260312/rustchain-miner.service \
+ ~/.config/systemd/user/
+
+# macOS
+cp ~/rustchain-backup/20260312/com.rustchain.miner.plist \
+ ~/Library/LaunchAgents/
+```
+
+#### 步骤 4：重新配置服务（如需要）
+
+如果硬件发生变化，可能需要重新安装矿工：
+
+```bash
+# 使用相同的钱包名称重新安装
+curl -sSL https://raw.githubusercontent.com/Scottcjn/Rustchain/main/install-miner.sh | \
+ bash -s -- --wallet your-wallet-name
+```
+
+#### 步骤 5：启动并验证
+
+```bash
+# Linux
+systemctl --user daemon-reload
+systemctl --user enable rustchain-miner --now
+systemctl --user status rustchain-miner
+
+# macOS
+launchctl load ~/Library/LaunchAgents/com.rustchain.miner.plist
+launchctl start com.rustchain.miner
+
+# 验证
+curl -sk https://rustchain.org/health | jq .
+curl -sk "https://rustchain.org/wallet/balance?miner_id=your-wallet-name" | jq .
+```
+
+---
+
+## 自动化备份脚本
+
+### 备份脚本
+
+创建 `~/rustchain-backup.sh`：
+
+```bash
+#!/bin/bash
+# RustChain 自动备份脚本
+
+set -e
+
+BACKUP_DIR="$HOME/rustchain-backup"
+DATE=$(date +%Y%m%d_%H%M%S)
+BACKUP_PATH="$BACKUP_DIR/$DATE"
+
+echo "🔧 RustChain 备份开始..."
+
+# 创建备份目录
+mkdir -p "$BACKUP_PATH"
+
+# 停止服务
+echo "⏹️ 停止矿工服务..."
+if command -v systemctl &>/dev/null; then
+ systemctl --user stop rustchain-miner 2>/dev/null || true
+elif command -v launchctl &>/dev/null; then
+ launchctl stop com.rustchain.miner 2>/dev/null || true
+fi
+
+# 备份数据
+echo "💾 备份矿工数据..."
+cp -r ~/.rustchain "$BACKUP_PATH/rustchain-data"
+
+# 备份配置
+if [ -f "$HOME/.config/systemd/user/rustchain-miner.service" ]; then
+ cp "$HOME/.config/systemd/user/rustchain-miner.service" "$BACKUP_PATH/"
+fi
+
+if [ -f "$HOME/Library/LaunchAgents/com.rustchain.miner.plist" ]; then
+ cp "$HOME/Library/LaunchAgents/com.rustchain.miner.plist" "$BACKUP_PATH/"
+fi
+
+# 记录钱包信息（需要手动填写）
+echo "⚠️ 请手动记录您的钱包名称到：$BACKUP_PATH/wallet-name.txt"
+
+# 清理旧备份（保留最近 5 个）
+cd "$BACKUP_DIR"
+ls -t | tail -n +6 | xargs -r rm -rf
+
+# 重启服务
+echo "▶️ 重启矿工服务..."
+if command -v systemctl &>/dev/null; then
+ systemctl --user start rustchain-miner 2>/dev/null || true
+elif command -v launchctl &>/dev/null; then
+ launchctl start com.rustchain.miner 2>/dev/null || true
+fi
+
+echo "✅ 备份完成：$BACKUP_PATH"
+echo "📦 备份大小：$(du -sh "$BACKUP_PATH" | cut -f1)"
+```
+
+使用：
+```bash
+chmod +x ~/rustchain-backup.sh
+~/rustchain-backup.sh
+```
+
+### 定时备份（Cron）
+
+```bash
+# 编辑 crontab
+crontab -e
+
+# 添加每周备份（每周日 2:00 AM）
+0 2 * * 0 /home/youruser/rustchain-backup.sh >> /home/youruser/rustchain-backup.log 2>&1
+```
+
+---
+
+## 故障排除
+
+### 问题 1：恢复后矿工不启动
+
+**检查服务状态：**
+```bash
+# Linux
+systemctl --user status rustchain-miner
+journalctl --user -u rustchain-miner -n 50
+
+# macOS
+launchctl list | grep rustchain
+tail -f ~/.rustchain/miner.log
+```
+
+**常见原因：**
+- Python 虚拟环境路径不正确
+- 服务配置文件中的路径需要更新
+- 权限问题
+
+**解决方案：**
+```bash
+# 重新设置虚拟环境
+cd ~/.rustchain
+rm -rf venv
+python3 -m venv venv
+./venv/bin/pip install requests -q
+```
+
+### 问题 2：钱包余额显示为 0
+
+**检查：**
+```bash
+# 确认钱包名称正确
+cat ~/rustchain-backup/*/wallet-name.txt
+
+# 查询矿工列表
+curl -sk https://rustchain.org/api/miners | jq .
+
+# 确认矿工在线
+curl -sk https://rustchain.org/health | jq .
+```
+
+**可能原因：**
+- 钱包名称不匹配
+- 矿工尚未完成奖励周期
+- 网络延迟
+
+### 问题 3：服务配置加载失败
+
+**Linux systemd:**
+```bash
+# 重新加载配置
+systemctl --user daemon-reload
+systemctl --user enable rustchain-miner
+
+# 检查服务文件
+cat ~/.config/systemd/user/rustchain-miner.service
+```
+
+**macOS launchd:**
+```bash
+# 验证 plist 文件
+plutil -lint ~/Library/LaunchAgents/com.rustchain.miner.plist
+
+# 重新加载
+launchctl unload ~/Library/LaunchAgents/com.rustchain.miner.plist 2>/dev/null || true
+launchctl load ~/Library/LaunchAgents/com.rustchain.miner.plist
+```
+
+### 问题 4：硬件变更后的恢复
+
+如果更换了硬件（主板、CPU 等），硬件指纹会改变，需要：
+
+1. **使用相同钱包名称重新安装：**
+```bash
+curl -sSL https://raw.githubusercontent.com/Scottcjn/Rustchain/main/install-miner.sh | \
+ bash -s -- --wallet your-wallet-name
+```
+
+2. **重新进行硬件认证：**
+```bash
+# 等待矿工自动完成认证
+# 查看日志确认
+tail -f ~/.rustchain/miner.log
+```
+
+3. **验证新硬件的挖矿状态：**
+```bash
+curl -sk https://rustchain.org/api/miners | jq .
+```
+
+---
+
+## 最佳实践
+
+### 备份频率建议
+
+| 场景 | 频率 |
+|------|------|
+| 日常运行 | 每周一次 |
+| 升级前 | 必须备份 |
+| 硬件变更前 | 必须备份 |
+| 系统重装前 | 必须备份 |
+
+### 备份存储建议
+
+1. **本地备份**：快速恢复
+2. **外部存储**：USB 驱动器、外部硬盘
+3. **云存储**：加密后上传到云盘
+4. **多份拷贝**：至少 2 份不同位置
+
+### 安全注意事项
+
+- ⚠️ **永远不要分享钱包名称给不可信的来源**
+- ⚠️ **备份文件加密存储**（包含敏感配置）
+- ⚠️ **定期测试恢复流程**（确保备份有效）
+- ⚠️ **记录钱包名称在安全位置**（离线存储）
+
+### 加密备份（可选）
+
+```bash
+# 使用 GPG 加密备份
+gpg -c ~/rustchain-backup/20260312.tar.gz
+# 输入密码保护
+
+# 恢复时解密
+gpg -d ~/rustchain-backup/20260312.tar.gz.gpg | tar -xz
+```
+
+---
+
+## 快速参考命令

+- ✅ `GET /api/miners` - 返回活跃矿工列表及硬件信息
+- ✅ `GET /wallet/balance?miner_id=test` - 返回钱包余额
+
+## 注意事项
+
+1. **SSL 证书**: RustChain 节点可能使用自签名 SSL 证书，在某些客户端中需要禁用证书验证
+2. **Governance 端点**: 部分治理端点可能返回 404（如果没有活跃提案）
+3. **Premium API**: x402 高级 API 端点目前免费使用（证明流程阶段）
+
+## 技术细节
+
+- **认证**: 无需认证（公开 API）
+- **格式**: 所有响应均为 JSON 格式（除 UI 页面外）
+- **速率限制**: 未文档化，建议合理请求

+
+## ⚠️ Notes
+
+### Self-Signed Certificate
+
+The RustChain API uses a self-signed certificate. All test configurations include:
+
+- Locust: `self.client.verify = False`
+- k6: `insecureSkipTLSVerify: true`
+- Artillery: `tls.rejectUnauthorized: false`
+
+### Rate Limiting
+
+The API implements rate limiting. Tests include:
+
+- Graceful handling of HTTP 429 responses
+- Exponential backoff recommendations
+- Rate limit behavior verification
+
+### Production Testing
+
+⚠️ **Warning:** These tests generate significant load. Use caution when testing against production instances.
+
+Recommendations:
+
+1. Start with low user counts (1-5 VUs)
+2. Gradually increase load
+3. Monitor API health during tests
+4. Have a rollback plan ready
+
+## 🐛 Troubleshooting
+
+### Connection Refused
+
+```bash
+# Check API availability
+curl -sk https://50.28.86.131/health
+```
+
+### Certificate Errors
+
+All tools are configured to accept self-signed certificates. If you see certificate errors, verify the configuration flags are set correctly.
+
+### High Failure Rates
+
+If failure rates exceed thresholds:
+
+1. Check API health manually
+2. Reduce concurrent users
+3. Increase timeouts
+4. Check network connectivity

+# RustChain Telegram Bot
+
+A Telegram bot for RustChain community that provides quick access to network information.
+
+## Features
+
+- `/balance ` - Check RTC balance for any wallet
+- `/miners` - List all active miners on the network
+- `/price` - Current wRTC price information
+- `/health` - Node health status
+- `/epoch` - Current epoch information
+
+## Setup
+
+### 1. Create Telegram Bot
+
+1. Open Telegram and search for `@BotFather`
+2. Send `/newbot` command
+3. Follow the prompts to name your bot
+4. Save the API token provided
+
+### 2. Install Dependencies
+
+```bash
+pip install -r requirements.txt
+```
+
+### 3. Configure Bot Token
+
+Edit `bot.py` and replace `YOUR_BOT_TOKEN_HERE` with your actual bot token:
+
+```python
+BOT_TOKEN = "1234567890:ABCdefGHIjklMNOpqrsTUVwxyz"
+```
+
+### 4. Run the Bot
+
+```bash
+python bot.py
+```
+
+## Usage
+
+Start a chat with your bot on Telegram and use the commands:
+
+- `/start` - Show welcome message and available commands
+- `/balance scott` - Check balance for wallet "scott"
+- `/miners` - See all active miners
+- `/health` - Check node health status
+- `/epoch` - Get current epoch info
+
+## API Reference
+
+This bot uses the RustChain API at `https://rustchain.org`:
+
+- `GET /health` - Node health status
+- `GET /epoch` - Current epoch info
+- `GET /api/miners` - List of miners
+- `GET /wallet/balance?miner_id={name}` - Wallet balance
+
+**Note:** The API uses a self-signed TLS certificate. The bot handles this automatically.
+
+## Deployment Options
+
+### Systemd Service (Linux)
+
+Create `/etc/systemd/system/rustchain-bot.service`:
+
+```ini
+[Unit]
+Description=RustChain Telegram Bot
+After=network.target
+
+[Service]
+Type=simple
+User=youruser
+WorkingDirectory=/path/to/telegram_bot
+ExecStart=/usr/bin/python3 /path/to/telegram_bot/bot.py
+Restart=always
+
+[Install]
+WantedBy=multi-user.target
+```
+
+Then:
+
+```bash
+sudo systemctl enable rustchain-bot
+sudo systemctl start rustchain-bot
+sudo systemctl status rustchain-bot
+```
+
+### Docker
+
+Create `Dockerfile`:
+
+```dockerfile
+FROM python:3.11-slim
+WORKDIR /app
+COPY requirements.txt .
+RUN pip install --no-cache-dir -r requirements.txt
+COPY bot.py .
+CMD ["python", "bot.py"]
+```
+
+Build and run:
+
+```bash
+docker build -t rustchain-bot .
+docker run -d --name rustchain-bot rustchain-bot
+```
+
+## Development
+
+### Adding New Commands
+
+1. Add a new async command handler function:
+
+```python
+async def mycommand_command(update: Update, context: ContextTypes.DEFAULT_TYPE):
+ data = await get_api("/my-endpoint")
+ await update.message.reply_text(f"Result: {data}")
+```
+
+2. Register the handler in `main()`:
+
+```python
+application.add_handler(CommandHandler("mycommand", mycommand_command))
+```
+
+## Troubleshooting
+
+### Bot doesn't respond
+
+- Check if the bot token is correct
+- Verify the bot is running (`python bot.py`)
+- Check logs for errors
+
+### API errors
+
+- The RustChain node might be temporarily unavailable
+- Check `https://rustchain.org/health` directly
+- Verify your internet connection
+
+### Certificate warnings
+
+The bot automatically handles the self-signed certificate. No action needed.
+
+## License
+
+MIT License - Feel free to modify and distribute.
+
+## Support
+
+For issues or feature requests, please open an issue on the rustchain-bounties repository.
