Quick Start

# Clone the repository
git clone https://github.com/opensyria/OpenSY.git
cd OpenSY

# Build
cmake -B build -DCMAKE_BUILD_TYPE=Release
cmake --build build -j$(nproc)

What is OpenSY?

OpenSY (SYL) is a cryptocurrency forked from Bitcoin Core, created to support the Syrian community with a modern, decentralized digital currency. It maintains Bitcoin's proven security model while introducing Syria-specific customizations.

Key Features:

• Currency: SYL (Syrian Lira digital)
• Address Prefix: Mainnet addresses start with 'F' (Freedom)
• Bech32 Prefix: syl1... (native SegWit)
• Network Port: 9633 (based on Syria's country code +963)
• Block Time: ~2 minutes
• Block Reward: 10,000 SYL (halves every ~4 years)
• Max Supply: 21 Billion SYL
• Genesis Date: December 8, 2024 (Syria Liberation Day)
• PoW Algorithm: RandomX (CPU-friendly, ASIC-resistant) - from block 1

Mining

⚡ RandomX - CPU-Friendly Mining from Day One

OpenSY uses RandomX proof-of-work from block 1!

Block	Algorithm	Hardware
Genesis (Block 0)	SHA-256d	Bootstrap only
Block 1+	RandomX	CPU

RandomX is an ASIC-resistant, CPU-optimized algorithm (used by Monero). This makes mining accessible to everyone with a regular computer from day one!

Why RandomX from Block 1?

• ✅ Fair launch - No ASIC/GPU advantage ever
• ✅ ASIC-resistant - No specialized hardware needed
• ✅ CPU-optimized - Your laptop can mine
• ✅ Truly decentralized - Levels the playing field from genesis
• ✅ Energy efficient - Lower power consumption

Solo Mining (CPU)

# Create a wallet
./build/bin/opensy-cli createwallet "my-wallet"

# Get a mining address
./build/bin/opensy-cli getnewaddress "mining"

# Mine blocks (CPU mining)
./build/bin/opensy-cli generatetoaddress 10 ADDRESS

CPU Mining Hardware

For optimal mining, consider high-core-count CPUs:

Recommended Hardware:

• AMD EPYC (64+ cores) - Best for RandomX
• Intel Xeon (32+ cores) - Good performance
• Any modern CPU with 8+ cores - Entry level

# Build and mine
cmake -B build -DCMAKE_BUILD_TYPE=Release
cmake --build build -j$(nproc)
./build/bin/opensy-cli generatetoaddress 100 YOUR_ADDRESS

Note: Block rewards require 100 confirmations (~3.3 hours) to mature.
