Driven by the surge of interest in blockchain and cryptocurrency platforms and the usefulness of such a building block in those areas, designing secure protocols to generate public randomness in a distributed manner has received considerable attention in recent years. This paper presents a systematization of knowledge on the topic of public randomness with a focus on cryptographic tools providing public verifiability and key themes underlying these systems. We provide concrete insights on how state-of-the-art protocols achieve this task efficiently in an adversarial setting and present various research gaps that may be of interest for future research. %Z This version is the author-accepted manuscript.
