As humanity takes its first resolute steps toward becoming a truly spacefaring civilization, we stand at the threshold of an epochal transition. To thrive across planets, moons, and the vast reaches between them, humankind requires a monetary foundation that is not tethered to any single world—a currency that is truly interplanetary, censorship-resistant, and capable of serving as an unbounded, timeless store of value.

Bitcoin, born on Earth yet designed without borders, is that monetary protocol. Yet its long-term security, decentralization, and resilience now demand a new frontier.

SpaceB exists to elevate Bitcoin into the cosmos.

We are building the orbital backbone that will ensure Bitcoin endures beyond terrestrial constraints. By deploying high-efficiency mining constellations in perpetual sunlight, we harness the inexhaustible power of the Sun itself—delivering near-constant energy, eliminating the volatility and scarcity of Earth-bound electricity, and securing complete geopolitical neutrality.

Every hash computed in orbit strengthens the network’s sovereignty. Every watt drawn from infinite solar flux fortifies Bitcoin’s immutability. Every mining node placed among the stars safeguards the protocol as humanity’s financial infrastructure expands to the Moon, Mars, and beyond.

SpaceB is not merely relocating computation; we are embedding the monetary nervous system of a multi-planetary species into the fabric of space.

We are ensuring that the sound money which liberated minds on one planet will continue to empower civilizations across many.

The future of money will not be confined to gravity wells.

It will orbit the Sun.

It will belong to the stars.

And SpaceB is making that future operational—today.
