League of Entropy
Publicly verifiable decentralized
Randomness-as-a-Service
We have you covered.
Whether you're a developer, researcher, or enthusiast in need of a publicly verifiable, reliable, and globally scalable source of randomness.

Our randomness beacons.
Harness the power of multiple, independent, high entropy sources to create a bias-resistant, unpredictable random number generator.

Why is randomness important?
Important societal processes
Many extremely important societal processes rely on randomness such as: jury selection, election event audits, tax audits, controlled trials, and lotteries.
Core technologies
Many of the core technologies that power our entire global computing infrastructure rely on randomness!
Gossip protocols
Randomly pick peers to disseminate information - randomness shields against eclipse attacks.
Cryptographic & encryption schemes
Nonces for encryption, Schnorr signatures, field parameters, ZKPs - randomness provides security guarantees.
Network routing
Tor (path selection) - randomness enables route anonymisation.
Consensus protocols
Omniledger (sharding), consensus protocols - randomness supports fair and secure leader election.
Members of the League
Welcome to the League of Entropy, where a consortium of public-minded organizations unites to forge a truly random beacon.
Unlike other randomness beacons, ours is the pioneering effort of multiple, unrelated entities working together in harmony, but at 'arms length' from an information security point-of-view.
Randomness beacons have traditionally been the domain of individual organizations leaving them vulnerable to manipulation by a single adversary.
However, by bringing together our founding members including Cloudflare, École Polytechnique Fédérale de Lausanne (EPFL), Kudelski Security, Protocol Labs, and the University of Chile, we've engineered the first unbiased beacon with cryptographic verification—an industry milestone.
