Decentralized Verifiable Random Functions (VRN)

VRN = Verifiable Random Number

A VRN is a function that creates a random number in decentralized fashion. The Outcome of this function can be verified by thirdparties. This is important to confirmt that the resulting number is truely (pseudo)random.

Properties of VRN

Desired properties of a VRNs are:

  • Availability/ Livelines
  • Quantum Resistence
  • Verifiability
  • Unbiased
  • Unpredictability
  • Scaleability
