ABSTRACT
Integration of systems like smart home, smart parking, and automotive controlling of things, etc. And the Internet of things (IoT) devices like actuators, sensors, and smartphones in our day-to-day life play an imperative function in developing modernized services and building up the technocity as more digitalized and smarter. The interconnection among many IoT objects for gathering varied data over the Internet to commence smart digital cities requires a tremendous amount of data creation, named big data. A huge amount of data has been created, owing to the miniaturization of the IoT smart devices increase. This crucial data will be of no use without the proper interpreter. The innumerable big data, IoT, and blockchain-distributed hyperledger framework will be enabled to attain the vital insight generated through the use of these smart devices. The increase in data created and collected via IoT had played a significant role in big data, which can be divided accordingly into three main features: the amount of space needed, quality of diversity, and speed. With the appearance of big data, management of quality as well as quantity is more required and most demanding than ever. Organizations that are merchandising with large datasets have to ensure that the data are immaculate, secure, and unchanged, and the source is authenticated along with the need to meet up with the new upgrading order to combine the data in real time at data centers. The data collected on the other side need validation – means of no duplication, exploration of data from the bulk of information collected over the devices, and for the better projection of the colossal amount of data. To sustain this kind of requirement, we need a technology known as the blockchain. Blockchain helps in managing and then translating in the other way, and the integration of these two acts as two sides of the same coin for providing the quality and quantity of the data. The main feature of blockchain technology is distributed ledgers, which help organizations to attain grasping big data. The combination of blockchain with big data brings the possibility of the new arriving challenges as organizing, unchangeable, and data integration. Security and transformation of gathered colossal data are not an easy process, and the use of blockchain technology along with the big data mutes all the underlying problems as of the following: scalability, real-time processing of the data, incorporation of data, and privacy preservation over the embedded devices called IoT along with the other two featured technologies.
