Blockchain-Based Threat Registry Platform

This document presents a reference architecture for a Blockchain-based Threat Registry platform, named BBTR, to share information about treats among different actors. The design of the BBTR guarantees integrity and availability of the data stored in it and is also compatible with privacy requirements, allowing different actors to participate as users of this shared BaaS (Blockchain as a Service). The paper also shows how this approach can be combined with AI techniques to extract valuable information from the threats directly from the Blockchain, empowering the final solution with a decision-making engine. It also includes its validation in a use case in the Health care domain.
