Understand

The DFINITY blockchain computer provides a secure, performant and flexible consensus mechanism.

At its core, DFINITY contains a decentralized randomness beacon which acts as a verifiable random function (VRF) that produces a stream of outputs over time.
The novel technique behind the beacon relies on the existence of a unique-deterministic, non-interactive, DKG-friendly threshold signatures scheme.
The only known examples of such a scheme are pairing-based and derived from BLS.
