How a Decentralized Randomness Beacon Could Boost Cryptographic Security

  • The League of Entropy is launching the first production-ready version of drand, a network that produces “randomness” (also known as entropy) for anyone to use.
  • Randomness is essential to cryptographic security.
  • Filecoin is the first protocol to use this version of drand in its upcoming mainnet launch to create decentralized, verifiable randomness for “leader selection.”

A novel cryptography piece, which could be of help to many cryptocurrency projects, is officially launching in production today.

The League of Entropy, which was launched last year, is opening the first production-ready version of drand, a network that produces “randomness” (also known as entropy) for anyone to use. Cryptography uses math and puzzles to secure communication in a way that snoops can’t untangle. Randomness is an essential piece of cryptography that ensures security by adding unpredictable information to the mix.

What is entropy (or randomness)?

Randomness is data produced in an unpredictable way. One example is rolling a six-sided dice. Before rolling it, you can’t predict which of the six numbers will appear.

You can even join together many dice rolls into a string of numbers. The more dice rolls done in a row, the more random and unpredictable the value.

A beacon is a randomness generator that shoots out random numbers at regular intervals, which anyone can look at and verify.

League of Entropy’s drand beacon network is unique in that it generates randomness in a new way that doesn’t rely on a single point of failure.

It’s analogous to having several dice rollers generating numbers and stringing them together, so no single one needs to be trusted.

The founding members, who will be running the beacon, are Cloudflare, École polytechnique fédérale de Lausanne (EPFL), Kudelski Security, Protocol Labs, and the University of Chile. Current membership has expanded to include C4DT, ChainSafe, cLabs, Emerald Onion, the Ethereum Foundation, IC3, PTisp, Tierion and
