PolySwarm or Poly swarm describes itself as the first decentralized marketplace where security experts build anti-malware engines that compete to protect you. Its domain Polyswarm.io was privately registered on the 19th day of October, 2018.

There is no information as to who owns or operates the website or platform. The admins of this website are largely anonymous. Most of the traffic flowing to the website comes from United Kingdom according to Alexa.

According to Polyswarm.io, "The PolySwarm market runs on Nectar, a token that will make it easy to submit and classify potential threats on the PolySwarm market. Nectar replaces traditional lump anti-virus and threat scanning subscription payments that are inefficiently distributed to a single vendor that doesn’t cover your variety of threats well."
