Mystiko-Blockchain Meets Big Data

Blockchain is a peer-to-peer distributed storage that stores chronological series of transactions in a tamper-resistant manner. Blockchain became popular in various industries due to its decentralized trust ecosystem. When integrating blockchain with big data, one encounters many challenges. Current public blockchain does not support high transaction throughput; it does not scale in terms of big data storage and management; it does not provide keyword-based search and retrieval; and so on. As a result, it is hard to incorporate existing blockchain systems for big data applications. In this research, we propose a new blockchain storage "Mystiko" that is built over the Apache Cassandra distributed database to incorporate big data. Mystiko supports high transaction throughput, high scalability, high availability and full text search features. With Mystiko, we make big data more secure, structured and meaningful, and allows further data analytics on big data to be more easily performed.
