A decentralized, open-source peer-to-peer Proof-of-Work cryptocurrency.

Wahacoin is a custom fork of Bitcoin Core (v22.0) utilizing the SHA-256 cryptographic algorithm. It is designed from the ground up for fair distribution and long-term network security through a progressive hardware rollout strategy.

Vahid Zekić — Designer, developer, and maintainer of the Wahacoin project.

Wahacoin was conceived, engineered, and is actively maintained by Vahid Zekić. All core protocol modifications, network architecture decisions, and the progressive decentralization strategy are his original work.

To prevent immediate network takeover by well-funded mining operations and to ensure stable, fair early distribution, Wahacoin employs a 3-Phase Hardware Rollout. The network is scaled physically through controlled phases of increasing computational power.

The network launches at zero difficulty. Block validation is handled exclusively by high-performance server-grade processors (e.g., Dual Intel Xeon architectures). This phase fosters early stability, allows core infrastructure to be battle-tested, and ensures that initial coin distribution is gradual and accessible.

• Mining is performed directly via wahacoind with setgenerate.
• No external mining software required.
• Focus: Network stability, wallet tooling, and peer discovery.

As network difficulty scales organically, GPU mining is introduced. CUDA-based setups and OpenCL miners connect to the node via the standard getblocktemplate RPC interface. This phase transitions the network away from CPU dominance and begins to establish a competitive hashrate floor.

• Miners connect via RPC (-rpcuser, -rpcpassword).
• Recommended: NVIDIA GPUs with cgminer or bfgminer (SHA-256 kernel).
• Focus: Hashrate growth, difficulty stabilization, exchange readiness.

Industrial-grade SHA-256 ASIC miners (e.g., Bitmain Antminer S19, Bitaxe Ultra) are connected to the network via Stratum V1/V2 mining pools. This locks the network difficulty at a high tier, providing ultimate cryptographic security equivalent to Bitcoin-class protection.

• Requires a Stratum-compatible mining pool (e.g., CKPool, OCEAN).
• ASICs connect to pool; pool connects to wahacoind via RPC.
• Focus: Industrial-grade security, global decentralization, long-term sustainability.

Wahacoin compiles as a standard C++ Autotools project. The following instructions target headless mining/validation nodes without GUI.

• macOS: Xcode Command Line Tools, Automake, pkg-config, libevent, Boost
• Linux (Debian/Ubuntu): build-essential, libtool, autotools-dev, automake, pkg-config, libevent-dev, libboost-all-dev

xcode-select --install
brew install automake libtool pkg-config libevent boost

sudo apt-get update
sudo apt-get install -y build-essential libtool autotools-dev automake \
  pkg-config libevent-dev libboost-system-dev libboost-filesystem-dev \
  libboost-thread-dev libsqlite3-dev

Clone the repository and build:

git clone https://github.com/vahidzekic/Wahacoin.git
cd Wahacoin

./autogen.sh

./configure \
  --disable-tests \
  --disable-bench \
  --without-gui \
  --without-bdb \
  CXXFLAGS="-Wno-enum-constexpr-conversion -D_LIBCPP_ENABLE_CXX17_REMOVED_UNARY_BINARY_FUNCTION"

make -j$(nproc || sysctl -n hw.ncpu)

Note: The CXXFLAGS above are required for modern Apple Clang (17+) and libc++ toolchains that have removed deprecated C++17 constructs used by the vendored Boost library.

./src/wahacoind -daemon

The node will create its data directory at:

• macOS: ~/Library/Application Support/Wahacoin/
• Linux: ~/.wahacoin/

Configuration file: wahacoin.conf

./src/wahacoin-cli getblockchaininfo    # Network status
./src/wahacoin-cli getmininginfo        # Mining statistics
./src/wahacoin-cli getpeerinfo          # Connected peers
./src/wahacoin-cli getnewaddress        # Generate a new WAHA address

Wahacoin nodes communicate over standard Bitcoin-derived protocols:

• P2P Network (port 9333): Block and transaction propagation between full nodes.
• JSON-RPC (port 9332): Programmatic interface for wallets, miners, and monitoring tools.
• ZeroMQ (optional): Real-time block/transaction notifications for external services.
