In the cryptocurrency era, Blockchain is one of the
expeditiously growing information technologies that help in
providing security to the data. Data tampering and authentication
problems generally occur in centralized servers while sharing and
storing the data. Blockchain provides the platform for big data
and cloud storage in enhancing the security by evading from
pernicious users. In this paper, we have discussed the exhaustive
description of blockchain and its need, features and applications.
Analysis of blockchain is done for different domains such as big
data, cloud, internet of things and mobile cloud where the
differences V’s are compared with big data and blockchain.
SWOT (Strength Weakness Opportunities Threats) analysis is
performed to address the merits and limitations in blockchain
technology. The survey in aspects of data security, data storage,
data sharing and data authentication through blockchain
technology is done and the challenges are discussed to overcome
the problem that leads in big data and cloud storage. The detailed
comparative analysis proves that the blockchain technology
overcomes the problems in big data storage and data security in
cloud.
