Summary
This post details the technical implementation of LavaRand, a system that uses a wall of lava lamps as a source of true randomness for cryptographic operations. It explains the concepts of true vs. pseudorandomness, the importance of randomness in cryptography, and how LavaRand integrates with Cloudflare's production systems to provide an additional layer of security by mixing entropy from physical processes with existing entropy sources.
