What is xCoin?
Bitcoin is Forked!
Don't hold your breath for Bitcoin. It will never be quantum-ready in time.
xCoin uses an entirely new proof-of-work algorithm called MetalDAG. It's very memory intensive — and that's the whole point.
Memory-hard means ASICs can't run the table. No warehouse advantage. No factory chokepoint. Mining stays on hardware you already own: a laptop, a gaming rig, a Mac (Macs are shockingly good at it). You can even mine it in your browser right now — 0% fee, forever.
Proof-of-work for people, not warehouses.
Everything else is Bitcoin's DNA, upgraded for what's coming:
Post-quantum from block one. Every signature is ML-DSA-65. The day a quantum computer guts legacy Bitcoin, xCoin doesn't blink.
21,000,000 hard cap. The same scarcity that made Bitcoin Bitcoin.
Flat 50 XAT per block, no halvings. The miners who secure the chain never get cliffed out.
One transparent 1,000,000-XAT founder stake at genesis — the only coins not mined. No ICO. No VC. No fine print.
And no king. xCoin runs on a public Constitution and a steward who keeps the door open, not the gate shut. Credibly neutral. One chain. Everything drawn to the center.
Bitcoin walked so xCoin could fork.
