About this episode
In this episode of the Crazy Wisdom podcast, host Stewart Alsop sits down with Daniel Bar, co-founder of Space Computer, a satellite-based secure compute protocol that creates a "root of trust in space" using tamper-resistant hardware for cryptographic applications. The conversation explores the fascinating intersection of space technology, blockchain infrastructure, and trusted execution environments (TEEs), touching on everything from cosmic radiation-powered random number generators to the future of space-based data centers and Daniel's journey from quantum computing research to building what they envision as the next evolution beyond Ethereum's "world computer" concept.

Space-based data centers solve the physical security problem for Trusted Execution Environments (TEEs). While TEEs provide secure compute through physical isolation, they remain vulnerable to attacks requiring physical access - like electron microscope forensics to extract secrets from chips. By placing TEEs in space, these attack vectors become practically impossible, creating the highest possible security guarantees for cryptographic applications.2. The space computer architecture uses a hybrid layer approach with space-based settlement and earth-based compute. The layer 1 blockchain operates in space as a settlement layer and smart contract platform, while layer 2 solutions on earth provide high-performance compute. This design leverages space's security advantages while compensating for the bandwidth and compute constraints of orbital infrastructure through terrestrial augmentation.3. True randomness generation becomes possible through cosmic radiation harvesting. Unlike pseudo-random number generators used in most blockchain applications today, space-based systems can harvest cosmic radiation as a genuinely stochastic process. This provides pure randomness critical for cryptographic applications like
