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

Randomness as Infrastructure

Randomness is the invisible foundation of digital security. Every security key ever created, and every encrypted message ever sent depends on a random number that nobody could have predicted. In February 2025, North Korean hackers executed the largest cryptocurrency theft in history, stealing $1.5 billion in ETH from Bybit.

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 Providing Reliable True Randomness from the Tamper-Proof Decentralized Orbital Network

Among the multitude of SpaceComputer's interstellar and earthbound missions, is to reliably provide true randomness from our tamper-proof decentralized orbital network. This blog will cover the need for entropy as well as the underlying architecture currently being employed to achieve this mission. Entropy and Random Number Generators (RNGs)
