Cloud computing is one of the greatest inventions. It is the need of today's generation. It freed mankind from storing the large quantity of data on physical hardware. It helps the users to access their data online from anywhere and at any time. Today, whether an individual or group of organization everyone is bound to use this technology. Many organizations have shifted their whole data centre on the cloud and are free from maintaining it physically. But with many benefits and advantages, it has some implications (Rohith & Anand, 2018) . As we all know, today everyone's data (audio, video, documents, texts, bank data, etc) is somehow stored on the cloud because no one wants to waste their time in managing those data but with this, a major threat to data integrity is increasing day by day. Current cloud computing market is at risk. Many cyber attacks are happening every day. Data are the major target for the cyber attacks, which undermines the fundamental properties like confidentiality, integrity, authenticity. Compromising confidentiality discloses private data and compromising with data integrity is harmful as it totally tampers the data by deleting some of the important files or alter it in order to produce an unauthorised effect. Once the data integrity is compromised it is difficult to retrieve data as it is lost forever. Due to all these problems the new concept has arrived, the concept of blockchain (Hashmi, et al., 2018) . Blockchain is also one of the best inventions of today. The reason many digital currencies, cryptocurrencies have made a great impact on the market. This technology is not just for digital currency but on many other sectors as well. It also made a great impact on the cloud market. Many problems of the cloud have come to end by using blockchain technology. Many big organizations have started implementing and practising this technology on the cloud to remove a major threat to data on the cloud and make it smoother for users to use. Blockchain is based
