Solar Bitcoin mining in low Earth orbit. SpaceB starts with a kW-scale LEO demonstrator. The resource is not scarce. The jurisdiction is.

THESIS STRIP

Bitcoin mining is an energy and jurisdiction problem. Terrestrial sites compete for power contracts, permitting, and political continuity. Orbit offers continuous solar access and a different legal posture — not a promise of absolute resistance to seizure, but a design that is more seizure-resistant than many ground deployments. SpaceB focuses on solar-powered ASIC mining in LEO. We start with a demonstrator that can prove thermal, power, and downlink reality at kilowatt scale.

ARCHITECTURE

PV → ASICs → radiators → RF or laser downlink multisig custody. Power is collected on orbit, converted and delivered to mining ASICs, rejected as heat through radiators sized for the space environment, and settled through a downlink path into multisignature custody on the ground. Public materials stay at this architectural level.

WHY NOW

Launch and space systems capability continue to improve. The public question for SpaceB is technical and jurisdictional: can a kW-class LEO system run ASICs with credible thermal design, usable system density, and a workable custody path — before anyone talks about scale.

DEMONSTRATOR TEASER

Phase I is a kW-scale LEO demonstrator. Success is defined by radiation tolerance, radiator mass and deployment, system watts per kilogram, downlink integrity, and ASIC thermal cycling under orbital conditions. Details for diligence sit behind the gated white paper.
