Polyswarm is a decentralized threat intelligence marketplace enabled by Ethereum smart contracts and blockchain technology. It defines where threat intelligence comes from and how to digest bad (inaccurate) threat intelligence to get good threat intelligence.

PolySwarm facilitates rapid innovation in the $8.5 billion-a-year cyber threat intelligence field using a precision economics approach, providing timely and accurate malware identification to a global community of security experts.

Background introduction

Today's businesses rely primarily on a specific combination of antivirus subscriptions, dynamic threat intelligence, and complementary dynamic analysis engines to combat ongoing cyber-malicious activity. Users must consider the advantages and disadvantages of each solution and choose a relatively suitable combination according to their own situation.
Current market models are not conducive to solutions that provide broad threat coverage.
Current solutions focus on the comfort zone of the threat - making the current market economy.

In general, it is common (and perhaps reasonable) for anti-virus solutions to ignore WannaCry³ (ransomware); but in doing so, the current market only effectively rewards vendors for previously overlapping reach, resulting in duplication costs This inefficient market phenomenon is a typical tragedy of public goods.
Similarly, imagine that a supplier chooses to develop protection outside the comfort zone, but this comfort zone defines the threats faced by most enterprises, and it will be difficult for this supplier specializing in a specific direction to find a good market. How can you convince potential customers that they are going to be confronted with a type of malware that we are the only ones in the market qualified to detect, prevent, or mitigate?
Finally, combined coverage is impossible in many cases due to the inability to mix and match many of today's solutions.
By contrast, PolySwarm will foster a broad ecosystem of thousands of "micro-engines" (working engines), each developed by information security experts around the world.

                      In short, PolySwarm provides instant access to extensive crowdsourced information security expertise. Need to quickly identify a suspicious document? All you have to do is Swarm It™.
