## What is Palladium Core?

Palladium Core is a decentralized cryptocurrency built on Bitcoin's proven codebase, enhanced with modern features including **Taproot support** (BIP340/341/342/350). Designed for the palladium market ecosystem, it delivers enterprise-grade security, efficiency, and privacy for digital transactions.

### Key Features

- **Taproot Support (v2.0.0)**: Enhanced privacy with Schnorr signatures and bech32m addresses
- **Security**: Advanced cryptographic techniques ensure transaction security and fund protection
- **Efficiency**: Optimized blockchain parameters provide fast and reliable transaction processing
- **Transparency**: Open-source architecture enables community inspection and contribution
- **Market-Focused**: Tailored features specifically designed for palladium industry requirements
- **Decentralized**: Peer-to-peer network with no central authority

### What's New in v2.0.0

Palladium Core 2.0.0 introduces **full Taproot support**, bringing cutting-edge privacy and efficiency improvements:

- **Schnorr Signatures**: More efficient and secure than traditional ECDSA signatures
- **Bech32m Addresses**: New address format (`plm1p...`) for Taproot outputs
- **Enhanced Privacy**: Complex smart contracts appear as simple transactions on-chain
- **Smaller Transactions**: Lower fees through more efficient signature schemes

## Quick Start

### Pre-built Binaries

Download the latest Palladium Core release:

**[Download Latest Release (v2.0.0)](https://github.com/palladium-coin/palladiumcore/releases/latest)**

**Installation Steps:**

1. **Download**: Get the appropriate binary for your operating system
2. **Install**: Extract and run the installer
3. **Configure**: Create `palladium.conf` (see [Configuration](#configuration) below)
4. **Launch**: Start Palladium Core and sync with the network

**First-time users?** Check out the [Taproot User Guide](doc/taproot-guide.md) to learn about creating modern Taproot addresses with enhanced privacy.

### Configuration

For enhanced connectivity and performance, you can create a configuration file. Palladium Core supports comprehensive configuration options for mainnet, testnet, and regtest networks.

**Configuration File Location:**
- **Windows**: `%appdata%/Palladium/`  
- **Linux**: `/home/[username]/.palladium/`  
- **macOS**: `~/Library/Application Support/Palladium/`

Create a file named `palladium.conf` in the appropriate directory for your operating system.

**Complete Configuration Guide:**
For detailed configuration instructions, network-specific settings, security best practices, and complete configuration examples, please refer to our comprehensive configuration guide: **[Palladium Configuration File Documentation](doc/configuration-file.md)**

## Building from Source

### Docker Build (Recommended)

For a simpler and more reproducible build process, you can use our Docker-based build system. This method provides a consistent build environment and eliminates dependency management issues.

**Requirements:**
- Linux AMD x86_64 system with Ubuntu 20.04 or newer
- Docker installed and running

For detailed instructions and configuration options, see the [docker-build](docker-build/) directory.

### Manual Build Instructions

## Manual Build Instructions

### Quick Build Script (Ubuntu/WSL Only)

**For rapid development and debugging on Ubuntu 20.04 or WSL with Ubuntu 20.04**

We provide a convenient automated build script designed specifically for quick development iterations and GUI testing:

```bash
./quick-build.sh [OPTIONS]
```

**⚠️ Important Note**: This script is optimized for **Ubuntu 20.04** (including WSL with Ubuntu 20.04). It may not work correctly on newer Ubuntu versions due to dependency differences.

#### Available Options:

- `--full` or no arguments: Complete build process (dependencies + BerkeleyDB + compilation) [DEFAULT]
- `--build`: Full build with reconfigure (runs distclean, configure, and make)
- `--rebuild`: Quick incremental rebuild (clean + make, no reconfigure) - **fastest for testing**
- `--install-deps`: Install system dependencies only
- `--install-db`: Install BerkeleyDB 4.8 only
- `--clean`: Clean build artifacts
- `--help`: Show help message

#### Usage Examples:

```bash
# First time setup (installs everything)
./quick-build.sh

# Full rebuild after configuration changes
./quick-build.sh --build

# Quick rebuild after code changes (fastest)
./quick-build.sh --rebuild

# Clean build artifacts
./quick-build.sh --clean
```

#### What It Does:

- **Automated dependency installation**: Installs all required build tools, libraries, and Qt5 for GUI
- **BerkeleyDB 4.8 setup**: Automatically installs BerkeleyDB 4.8 (required for wallet functionality)
- **Optimized compilation**: Uses all available CPU cores with `make -j$(nproc)`
- **ccache support**: Automatically enables ccache for faster recompilation
- **GUI support**: Builds `palladium-qt` for testing the graphical interface

#### Output Binaries:

After successful build, binaries are located at:
- `src/palladiumd` - Daemon
- `src/palladium-cli` - Command-line interface
- `src/qt/palladium-qt` - Qt GUI application

#### Build Workflow Recommendation:

1. **First time**: `./quick-build.sh` (installs everything)
2. **After code changes**: `./quick-build.sh --rebuild` (fastest, keeps configuration)
3. **After configure changes**: `./quick-build.sh --build` (reconfigures everything)
