SpaceComputer

Earlier this month, SpaceComputer advisor Dahlia Malkhi shared the most detailed breakdown of SpaceComputer yet, “Building Orbital Root of Trust with State-of-Art Technology.”  

The vision: sovereign computation in orbit that can survive even if Earth’s infrastructure fails, preserving trust-minimized systems for the future.

This thread distills her talk: from why space offers unmatched security, to the architecture and functionality, to where builders can get involved.

We build on a growing space ecosystem, where we can utilize global connectivity from Iridium’s Low Earth Orbit (LEO) satellite constellation, and an increasing number of providers enabling on-orbit compute devices (aka boxes or nodes).

Today’s reality: bandwidth is limited, latency is high. But within 10 years, these constraints will mostly disappear.

There are several advantages to the security of space.
Once launched securely into orbit, a compute node becomes:

→ Tamper-proof: physically unreachable
→ Delete-proof: erased data is gone forever
→ Jamming-resistant: secure ground zones prevent interference
→ Geolocation-attested: predictable orbits provide Sybil resistance

Satellite-based software is not without vulnerabilities.

As of now, the root of trust in the supply chain is less mature, ground station communication, and upgrading software are attack surfaces.

Many of these are considered vulnerabilities since this is a nascent technology. With time, it will evolve.
