The League of Entropy is a consortium of organizations that are working together to produce a truly random beacon.
This is the first time ever that a randomness beacon is run by several organizations in concert: Cloudflare, École polytechnique fédérale de Lausanne, Kudelski Security, Protocol Labs, UChile, ChainSafe, cLabs, C4DT, Emerald Onion, Ethereum Foundation, IC3, PTisp, Tierion, and UCL.
Every other existing randomness beacon is generated by an individual entity. This means that an adversary needs to only take control of one party to tamper with randomness. Cloudflare, along with other organizations and security experts, is creating a global unbiased beacon that can be cryptographically verified, an industry first.
