+### RISC-V in RustChain
+
+RISC-V is classified as **EXOTIC** architecture with a **1.4x** antiquity multiplier in RustChain's RIP-PoA (Proof-of-Antiquity) system.
+
+| Architecture | Multiplier | Class | Notes |
+|-------------|------------|-------|-------|
+| RISC-V 64-bit | **1.4x** | EXOTIC | Open ISA, future-proof |
+| RISC-V 32-bit | **1.3x** | EXOTIC | Limited support |
+
+## 🚀 Quick Start
+
+### Option 1: Build with Cross (Recommended)
+
+```bash
+# Navigate to miner directory
+cd rustchain-miner
+
+# Build for RISC-V (release mode)
+./scripts/build_riscv.sh --release
+
+# Or use cross directly
+cross build --target riscv64gc-unknown-linux-gnu --release
+```
+
+### Option 2: Docker Build
+
+```bash
+# Build using Docker (works on any platform)
+./scripts/build_riscv.sh --docker --release
+```
+
+### Option 3: Native Cross-Compile
+
+```bash
+# Install RISC-V toolchain (Ubuntu/Debian)
+sudo apt-get install gcc-riscv64-linux-gnu g++-riscv64-linux-gnu
+
+# Build
+cargo build --target riscv64gc-unknown-linux-gnu --release

+## 📊 Performance
+
+### Expected Hash Rates
+
+| Device | CPU | Cores | Hash Rate | Power |
+|--------|-----|-------|-----------|-------|
+| VisionFive 2 | JH7110 | 4 | ~50 H/s | 5W |
+| HiFive Unmatched | U74 | 5 | ~80 H/s | 8W |
+| Nezha (D1) | C906 | 1 | ~15 H/s | 2W |
+
+### Optimization Tips
+
+1. **Use release mode**: Always build with `--release` for 10x performance
+2. **Enable LTO**: Link-time optimization in `Cargo.toml`
+3. **Tune for CPU**: Use `-C target-cpu=native` if building on-device
+4. **Reduce memory**: Use musl build for embedded devices
+
+## 🔍 Architecture Detection
+
+The miner automatically detects RISC-V implementations:
+
+| CPU String | Machine | Detected As |
+|------------|---------|-------------|
+| "SiFive U74" | riscv64 | RISC-V / SiFive U74 |
+| "StarFive JH7110" | riscv64 | RISC-V / StarFive JH7110 |
+| "VisionFive" | riscv64 | RISC-V / VisionFive |
+| "Allwinner D1" | riscv64 | RISC-V / Allwinner D1 |
+| "T-Head C910" | riscv64 | RISC-V / T-Head C910/C906 |
+| (generic) | riscv64 | RISC-V / RISC-V 64-bit |
+
+## 🐛 Troubleshooting
+
+### Build Errors
+
+**Error: linker not found**
+```bash
+# Install RISC-V toolchain
+sudo apt-get install gcc-riscv64-linux-gnu
+```
+
+**Error: OpenSSL not found**
+```bash
+# Install OpenSSL dev package
+sudo apt-get install libssl-dev
+# Or set environment variables
+export OPENSSL_INCLUDE_DIR=/usr/include
+export OPENSSL_LIB_DIR=/usr/lib/riscv64-linux-gnu
+```
+
+**Error: target not found**
+```bash
+# Add RISC-V target
+rustup target add riscv64gc-unknown-linux-gnu
+```
+
+### Runtime Errors
+
+**Error: cannot execute binary file**
+- Ensure you built for the correct target (gnu vs musl)
+- Check binary with `file rustchain-miner`
+- Verify with `readelf -h rustchain-miner`
+
+**Error: library not found**
+- For glibc builds, install dependencies on target device
+- For musl builds, ensure static linking worked
