When the threat is global, the response should be, too.

Every day, more than 100,000 new malicious IP addresses are launched. With both public and private sector organizations facing an increasingly complex range of cyber threats, we set out to build a fast and decentralized yet secure system to give the good guys an edge.

We decided to use blockchain as the primary data store because its decentralized nature removed the need for a central authority to manage and maintain knowledge. Also, its real-time nature allows information to be shared across organizations in the fast-moving cyber security world. For proof of concept, we used 2 nodes on Amazon Web Services running the open-source blockchain software, MultiChain.

In addition, we built a Python SDK to allow developers to automate accessing, updating, and acting on intelligence.
