The Randomness Illusion: Why Cloudflare's Approach to Entropy Falls Short

Cloudflare's iconic wall of lava lamps appears to demonstrate serious commitment to cryptographic security, but this analysis reveals a fundamental misunderstanding of what randomness actually means. The article distinguishes between randomness as an intrinsic property versus randomness as a function of knowledge, showing that lava lamps fail on the most important criterion. For organizations building encryption systems, understanding true entropy requirements is critical to avoiding the trap of security theater.
