How Cloudflare and Wall Street Are Helping Encrypt the Internet Today

On September 14, 2019, Cloudflare went public on the New York Stock Exchange. To celebrate this event, they brought their favorite entropy machines, lava lamps, to the trading floor of NYSE. The footage of these lava lamps is being used as an additional seed for their entropy-generation system LavaRand, which helps secure over 20 million Internet properties worldwide. Lava lamps are a fantastic source of entropy due to their unpredictable nature. Cloudflare has a wall filled with dozens of lava lamps in its San Francisco headquarters and uses an algorithm called LavaRand to amplify the randomness from these lava lamps. They also facilitate the League of Entropy, a consortium generating verifiable randomness via a globally distributed network.
