Chaos in Cloudflare’s Lisbon office: securing the Internet with wave motion

Cloudflare announces a new Lisbon office installation—a 50-unit wave-machine “wall of entropy”—that augments its LavaRand system by capturing real-world chaotic motion to seed CSPRNGs used across its infrastructure (e.g., TLS, Workers, drand). The post details the custom devices’ design and operation, how camera-captured motion is hashed and combined with system entropy via a KDF, and highlights the maritime-inspired office design and a public poll to name the installation.
