On January 20, Ryan Pierce and Andrew Miller—a self-described “know-how architect” and assistant professor of electrical engineering on the University of Illinois, respectively—climbed into Pierce’s prop aircraft with a Geiger counter, some radioactive materials from

The radioactive exercise within the Chernobyl materials utilized by Pierce and Miller is a results of the decay of Caesium-137 and Strontium-90, which leads to the discharge of ionizing radiation within the type of beta particles (excessive power electrons) and gamma rays. A Geiger counter measures ionizing radiation, which registers on the Geiger counter as a pulse of electrical energy and is used to measure radiation from a supply.

Since the electrons within the gasoline are randomly “knocked free” by the radiation, Pierce and Miller had been in a position to make use of the time variations between consecutive electrical pulses registered by the Geiger counter because the random supply for producing their partial parameter. Their setup was comparatively easy and consisted of a $100 Geiger counter package modified to behave as a random quantity generator.

So if you happen to ever use zk-SNARKs on the subsequent ZCash launch, relaxation simple understanding that not less than a part of the community’s safety was generated on an airborne, air gapped laptop and derived its entropy from the quantum mechanics of radioactive decay. Good luck hacking that.
