Chapter 12 - Blockchain-based big data platforms for sustainable smart cities

Abstract

Implementing cloud computing, big data, and Internet of Things technologies (IoT) extensively will make people' lives more convenient as information technology continues to advance at a rapid rate and encourages the establishment of new smart cities. The security nature of blockchain has more potential to improve the big data applications and services. The advancement of blockchain technology creates more opportunities for the development of smart cities. Blockchain plays the role to acquire, store, analyze, and preserve the privacy of the data. Building a big data platform for smart cities using blockchain and other emerging technologies can implement a point-to-point communication system, smart IoT, and government operations. This can also result in a more trustworthy trust agreement over time. Breaking down information islands and achieving the goals of sharing of data and information security using the blockchain and platform of big data creates a new kind of smart city. Cities which are making their move toward smart cities must take this important secure platform into consideration. To comprehend the issues that arise in the process of developing a smart city on a big data platform, it is imperative that the study and analysis of blockchain technology be strengthened in this connection. This article explores the benefits and related tactics of a blockchain-based big data platforms for smart cities.
