Space Infrastructure for Safe Computation: Talk by Filip and Toufic at EthCC

Last week, CoFounder Filip Rezabek and Applied cryptographer Toufic Batrice from the SpaceComputer team attended the Ethereum Community Conference (EthCC) in Cannes, France. They gave a talk 'Stars to Bits: Space Infrastructure for Safe Computation' which focused on the opportunity, challenges, and applications of building in Low Earth

Satellite Security Services in Low Earth Orbit

SpaceComputer delivers satellite security services from low Earth orbit: confidential compute, key management, and verifiable randomness, all accessible through a single API on Orbitport.

Orbitport: The Gateway to Space

Orbitport: The Gateway to Space

Hello Earthlings! Space computing today feels like a strange split reality: on one hand, we are building a future filled with paradoxes—laser communications beaming data across orbit, moon based hotels, and ambitious timelines for human travel to Mars. On the other hand, much of our actual interaction with space

Verifying True Randomness in Cryptographic Systems

Verifying True Randomness in Cryptographic Systems

Randomness is a foundational primitive in cryptographic protocols. It underpins security properties such as unpredictability, fairness, privacy, and resistance to adversarial manipulation. Key generation, nonces, salts, signatures, leader election, lotteries, and many consensus mechanisms all rely on randomness behaving as assumed. When randomness is weak, biased, predictable, or manipulable, entire

SpaceComputer Secure Key Management Services Beyond the Cloud

Key management services (KMSs) are foundational to modern cryptographic infrastructure. At SpaceComputer we are building KMS services beyond terrestrial cloud infrastructure.

Decentralized Small Satellites and why they matter for SpaceComputer

A constellation of smallsats can do what a single large satellite did, and no single entity or government holds the keys. The network is permissionless infrastructure

SpaceComputer Mission and Technical Vision

At Frontier Forum with Daniel Bar and Filip Rezabek All right, so for the beginning of the session, we'll share a little bit of insight into what brought us the motivation to work in space and how the space sector currently looks like. So what does spacefaring mean
