Using blockchains to enable Big Data analysis of private information

Blockchains were initially introduced in 2009, and since then, they have evolved into a revolutionary technology that has affected, not only the digital world but also our everyday lives and activities. Blockchain systems and architectures continue to grow at a fast rate, constantly introducing innovative solutions across multiple research topics. However, despite their wide adoption by the research community, the technology is still not mature enough to address the problems of business use cases. Issues like scalability, complexity, cryptocurrencies’ market fluctuations etc. prevent the proposed solutions from being widely accepted. Based on this observation this paper introduces an innovative solution to enable Big Data analysis of private information using blockchains. This solution is based on the Hyperledger Fabric blockchain and is able support the strict privacy and security requirements of operational and business environments.
