What is WATTx?

WATTx (ticker WTX) is a Bitcoin-lineage blockchain that keeps Bitcoin's UTXO model and 21 million coin cap while adding three things Bitcoin deliberately left out: an Ethereum Virtual Machine for smart contracts, a Proof-of-Stake layer that runs alongside Proof-of-Work, and a mining engine that accepts work from seven different hashing algorithms at once.

The chain is the settlement layer for WATTxchange, a multi-chain DeFi hub, and it is the reason WTX shows up on a Bitcoin forks list at all: the code descends from Bitcoin Core by way of Qtum, so the transaction format, script engine, address encoding and RPC surface will look immediately familiar to anyone who has run bitcoind.

Fast Facts

X25X — Seven Algorithms, One Chain

Most chains pick one hash function and live with the consequences: SHA-256 concentrates hashrate in ASIC farms, RandomX concentrates it in CPUs, Ethash in GPUs. WATTx's X25X engine accepts blocks from any of its supported algorithms and gives each one its own independent difficulty retarget, so a lull in GPU hashrate does not stall the chain and an ASIC farm cannot crowd out CPU miners.

Merged Mining: Get Paid Twice for One Hash

WATTx implements AuxPoW (auxiliary proof-of-work) — the same mechanism Namecoin pioneered against Bitcoin in 2011, generalised to seven parent chains instead of one. A miner points their hardware at a parent chain as usual; the pool embeds a commitment to a WATTx block inside the parent chain's coinbase transaction. When a share lands, it can satisfy the parent chain's target, WATTx's target, or both.

The practical result: the same hash earns BTC and WTX, or XMR and WTX, or KAS and WTX. There is no extra power draw and no separate rig — WATTx rides along on work you were already doing.

Consensus verifies the parent chain's proof-of-work canonically for every supported algorithm and binds it to the merge-mining commitment, so a WATTx block cannot be claimed with work that does not actually contain it.

The reference pool runs one stratum port per algorithm, numbered in algorithm order:

The public endpoint is pools.wattxchange.app, which is also the default the desktop wallet's Pool mining mode dials. XMRig speaks to the RandomX port directly; the SHA-256d, Scrypt and X11 ports speak standard Bitcoin stratum (mining.subscribe / mining.submit).

# CPU mining with XMRig, paid to your own WTX address
xmrig -o pools.wattxchange.app:3333 \
      -u WYourWattxAddressHere \
      -a rx/0 --keepalive

Your payout address must be present in the stratum login — either as the username, or appended as +WTX_ADDRESS. Logins with no usable address are refused rather than silently credited elsewhere.

Staking and Trust Tiers

Alongside mining, WATTx runs a Proof-of-Stake layer with registered validators and delegation. What makes it unusual is that staking rewards are weighted by measured uptime rather than stake size alone — validators accumulate a trust tier, and a higher tier earns a bonus on top of the base block reward:

Holders who do not want to run a node can delegate stake to a validator and receive a proportional share of that validator's rewards, minus the validator's configurable pool fee.

Smart Contracts, Taproot and Ordinals

• EVM on a UTXO chain. Inherited from Qtum's account abstraction layer, WATTx runs unmodified Solidity contracts on top of Bitcoin-style UTXOs. Standard Ethereum tooling connects through a JSON-RPC adapter at chain ID 22356. Gotcha for developers: msg.value is denominated in satoshis, not wei.
• Taproot from block zero. No activation drama, no BIP9 signalling window — Taproot and Schnorr signatures have been consensus-valid since genesis.
• Ordinals and inscriptions. Because Taproot is live, the Ordinals protocol works on WATTx the way it does on Bitcoin — witness-envelope inscriptions, sat-level tracking, and an indexer and marketplace of its own.
• Post-quantum addresses. WATTx ships a CRYSTALS-Dilithium signature type (addresses beginning with Q) alongside ECDSA and Schnorr, for anyone who wants lattice-based signatures today.
• Privacy research. An FCMP++ (full-chain membership proof) shielded-transaction layer is in development and disabled by default — treat it as experimental, not as a privacy guarantee.

Running a Node

# Linux x86-64
tar xzf wattx-0.1.7.7-linux64.tar.gz
cd wattx-0.1.7.7/bin

./wattxd -daemon
./wattx-cli createwallet "mywallet"
./wattx-cli getnewaddress
./wattx-cli getblockchaininfo

The node bootstraps from the seed1–seed3.wattxchange.app DNS seeds on port 1337. Desktop builds (Linux and Windows) ship a Qt wallet with solo and pool mining tabs built in; an Android wallet is published alongside each release.
