What is Threshold Relay?

Designed by the DFINITY team, Threshold Relay is the consensus mechanism used on the Internet Computer (ICP) protocol. Heavily optimized for Proof of Stake (PoS), Threshold Relay is a multi-layer system that makes use of a verifiable random function (VRF) to prove randomness and move data between node groups. This data transfer is the "relay" process the consensus mechanism is referring to and was designed to achieve fast transaction finality while balancing network consensus security concerns.
