Achieve incredible security, speed, and scale-out capacity in a network setting using concepts pioneered and implemented by DFINITY, including Threshold Relay and the Random Beacon.The Dfinity blockchain computer provides a secure, performant and flexible consensus mechanism. While first defined for a permissioned participation model, the consensus mechanism itself can be paired with any method of Sybil resistance (e.g. proof-of-work or proof-of-stake) to create an open participation model. Dfinity’s greatest strength is unfolded in the most challenging proof-of-stake case. 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.
