Abstract	Nowadays, Big Data is the most salient paradigm. It has become a game-changer in the current technology and has aroused various industries and research communities worldwide. Big Data-based applications have shown much potential in data-driven decisions that have changed all business operations, including cost optimization, online reputation, and customer loyalty. Nevertheless, Big Data also brings many security and privacy issues. For this reason, Big Data applications require accurate methods to ensure reliable data storage, sharing, and decision-making. Among these methods, the Blockchain is known as the clever combination of distributed exchange, consensus, and cryptography mechanisms. It has been brought to the forefront to resolve security challenges in various fields such as Healthcare, banking, smart cities, etc. This paper first presents the considerable difficulties faced when adopting Big Data that can be resolved using Blockchain. Afterward, we overview the Blockchain technology by projecting its components, workflows, classification, and related characteristics. Finally, we present the importance of combining Big Data and Blockchain through reviewing the novel implementations proposed by researchers in great domains. © 2022, The Author(s), under exclusive license to Springer Nature Switzerland AG.
