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

Cosmic dice from randomness in cryptographic systems, specifically SpaceComputer's cTRNG and randomness beacons, creating a new foundational service primitive.

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
