WATTx Core

WATTx is a hybrid Proof-of-Work/Proof-of-Stake blockchain featuring 7-algorithm merged mining (X25X), full EVM smart contract support, and full-chain privacy (FCMP+). Built on QTUM's foundation with significant enhancements for mining flexibility, cross-chain interoperability, and user privacy.

Key Features

Multi-Algorithm Mining (X25X)

Mine WATTx using any of 7 supported algorithms simultaneously via AuxPoW merged mining:

#	Algorithm	Target Hardware	Merged Coins (examples)
1	SHA256d	Bitcoin ASICs (Antminer S-series)	BTC, BCH, BSV, NMC, DOGE
2	Scrypt	Litecoin miners (Antminer L-series)	LTC, DOGE, FLO, DGB
3	Ethash	GPU miners (ETH-era cards)	ETC, CLO, EGEM, EXP
4	RandomX	CPU miners (Monero ecosystem)	XMR, WOW, OXEN, ARQ
5	Equihash	Zcash miners (miniZ, EWBF)	ZEC, ZEN, BTCZ, KMD, ARRR
6	X11	Dash ASICs (Antminer D-series)	DASH, DGB-X11, HTH, CANN
7	kHeavyHash	Kaspa miners (lolMiner, BzMiner)	KAS, KLS, PYI, SPR

Privacy Features (FCMP+)

• Full-Chain Membership Proofs — Monero-style ring signatures activating at block 210,000
• Shielded Commitments — Merkle tree commitments on the WATTx EVM
• Stealth Addresses — One-time addresses for unlinkable transactions
• Cross-Chain Privacy Pools — Anonymous cross-chain transfers with Monero-style privacy
• P2P Encrypted Messaging — End-to-end encrypted wallet-to-wallet chat

Smart Contracts

• Full EVM compatibility (Solidity)
• Built-in contract compiler
• Contract verification via block explorer

Hybrid Consensus

• PoW Mining — 7-algorithm X25X, 5 WTX per block
• PoS Staking — Dynamic stake maturity that halves with each reward halving, 5 WTX per block
• AuxPoW Merged Mining — Earn WTX while mining BTC, LTC, XMR, KAS, ETC, ZEC, DASH, and more

Cross-Chain Bridge

• LayerZero OFT token bridge
• Bridges between WATTx, Ethereum, BSC, Polygon

Quick Start

Download a Release

Pre-built binaries for Linux and Windows are available on the Releases page.

# Linux
tar -xzf wattx-0.1.7-linux64.tar.gz
cd wattx-0.1.7-linux64

# Start daemon
./wattxd -daemon

# Check sync status
./wattx-cli getblockchaininfo

Build from Source

Prerequisites: CMake 3.18+, GCC/Clang, Boost, OpenSSL, Berkeley DB 4.8, Qt5 (for GUI)

git clone https://github.com/WATTxChain/WATTx.git
cd WATTx
cmake -B build -DBUILD_GUI=ON
cmake --build build -j$(nproc)

Binaries will be in build/bin/:

• wattxd — daemon
• wattx-cli — CLI
• wattx-qt — GUI wallet
• wattx-wallet — wallet utility

Running a Node

# Start daemon
./wattxd -daemon

# Create wallet
./wattx-cli createwallet "mywallet"

# Get a receive address
./wattx-cli getnewaddress

# Check sync status
./wattx-cli getblockchaininfo

Mining (CLI)

# Check mining info
./wattx-cli getmininginfo

# Get network hashrate
./wattx-cli getnetworkhashps

# Generate blocks (regtest only)
./wattx-cli generatetoaddress 100 "your_address"

Mining (GUI)

1. Open wattx-qt
2. Go to Stake > Mining
3. Select mining mode (Solo / Pool)
4. Choose RandomX mode (Light 256 MB / Full 2 GB)
5. Set thread count
6. Click Start Miner

Pool Mining (AuxPoW Stratum)

Connect your existing mining hardware to earn WTX while mining your primary coin:

Algorithm	Stratum Port	Hardware
SHA256d	3333	Antminer S-series
Scrypt	3334	Antminer L-series
Ethash	3335	GPU (ETH-era)
RandomX	3336	CPU
Equihash	3337	miniZ / EWBF
X11	3338	Antminer D-series
kHeavyHash	3339	lolMiner / BzMiner

# SHA256d (BTC miners)
cgminer --url stratum+tcp://pool.wattxchain.org:3333 --user YOUR_BTC_ADDRESS.worker --pass x

# RandomX (CPU / XMR miners)
xmrig -o pool.wattxchain.org:3336 -u YOUR_XMR_ADDRESS -p worker

# kHeavyHash (Kaspa miners)
lolMiner --algo KASPA --pool pool.wattxchain.org:3339 --user YOUR_KAS_ADDRESS.worker

Staking

# Check staking status
./wattx-cli getstakinginfo

# Enable staking (wallet must be unlocked)
./wattx-cli walletpassphrase "yourpassphrase" 99999999 true
