Blockchain for Big Data Security, Issues, Challenges and Future Directions

Over the last decade, worldwide data traffic has risen at an unprecedented rate, prompting a surge in interest in big data. manufacturing, entertainment, and media. With this interest, Blockchain Technology, appeared as a promising technology that enables the transaction record to be continuously stored, protected with the digital signature, and validated by consensus. It operates under the concept of a digital ledger that is distributed. In this article, recent growth in blockchain interest as an alternative to traditional centralized systems has been presented and considered the emerging implementations thereof. In particular, the key approaches needed for the introduction of the blockchain and security issues. This includes the general issue behind the blockchain, description of the component, and the blockchain importance and connection with the big data. Thus, the paper focuses on reviewing the research in blockchain applications in securing big data. The paper compares big data security techniques and mechanisms provided by the blockchain approach considering security attacks that might shed light on Blockchain enthusiasts and researchers. Finally, the paper evaluates the various challenges of blockchain and put some recommendations for future research.
