WATTx Core

WATTx is a hybrid Proof-of-Work/Proof-of-Stake blockchain featuring multi-algorithm mining, smart contracts, and privacy-focused features. Built on QTUM's foundation with significant enhancements for mining flexibility, cross-chain interoperability, and user privacy.

Key Features

Multi-Algorithm Mining (X25X)

Mine using any of 7 supported algorithms:

Algorithm	Target Hardware
SHA256d	Bitcoin ASICs
Scrypt	Litecoin miners
RandomX	CPU miners (Monero)
Ethash	Ethereum Classic miners
Equihash	Zcash miners
kHeavyHash	Kaspa miners
X11	Dash miners

Privacy Features

• Cross-Chain Privacy Pools - Anonymous cross-chain USDT transfers with Monero-style privacy
• Shielded Commitments - Merkle tree commitments on WATTx EVM
• Stealth Addresses - One-time addresses for unlinkable transactions
• P2P Encrypted Messaging - End-to-end encrypted chat between wallet instances
• FCMP Privacy Transactions - Full-chain membership proofs (activates block 210,000)

Smart Contracts

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

Hybrid Consensus

• PoW Mining - Multi-algorithm support via X25X
• PoS Staking - Dynamic stake maturity that halves with block reward halvings
• AuxPoW Merged Mining - Mine WATTx while mining Monero, BTC, LTC, KAS, ALT, ETC (any coin with suppoprted algorithm)

Cross-Chain Bridge

• LayerZero-based OFT token bridge
• Bridge between WATTx, Ethereum, BSC, Polygon

Halving Interval	1,051,200 blocks (~4 years)	Same	200 blocks
Base Stake Maturity	500 blocks	500 blocks	20 blocks
Stake Maturity Floor	10 blocks	10 blocks	2 blocks
X25X Activation	Block 210,000	Block 1,000	Block 1
RandomX Activation	Block 210,000	Block 1,000	Block 1
FCMP Activation	Block 210,000	Block 1,000	Block 1
P2P Port	18888	13888	18444
RPC Port	18889	13889	18443

Quick Start

Running a Node

# Start daemon
./wattxd -daemon

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

# Get new address
./wattx-cli getnewaddress

# Check sync status
./wattx-cli getblockchaininfo

Mining (GUI)

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

Mining (CLI)

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

# Check mining info
./wattx-cli getmininginfo

# Get network hashrate
./wattx-cli getnetworkhashps

Staking

# Check staking status
./wattx-cli getstakinginfo

# Enable staking (wallet must be unlocked)
./wattx-cli walletpassphrase "your_passphrase" 999999999 true

Smart Contracts

# Deploy contract (via GUI or CLI)
./wattx-cli createcontract "bytecode" 1000000 0.00000040

# Call contract
./wattx-cli callcontract "contract_address" "data"

# Send to contract
./wattx-cli sendtocontract "contract_address" "data" 0 1000000

P2P Encrypted Messaging

1. Open wattx-qt
2. Go to Messaging
3. Create a chat identity
4. Add contacts by their public key
5. Send encrypted messages directly between wallets
