Webcryptographic sortition, in which a small ‘committee’ of protocol participants is selected periodically; a party is in the committee when its VRF output (on a certain public input) is within some specified range. The VRF’s uniqueness property helps to ensure that a party cannot improperly include itself in the committee, WebApr 25, 2024 · Hence, the Institution communicates through DEXON’s fair cryptographic sortition to achieve decentralization. DEXON applies a VRF-based sortition algorithm to select a subset of nodes as block producers, allowing DEXON to scale to a large number of nodes, making the whole system fully decentralized.
