Abstract

AbstractThe advent of cloud computing has ensured a fertile soil for efficiently handling distributed computing. However, it calls for the provisioning of high-configuration infrastructure, including advanced servers and high-bandwidth networks for augmenting storage and computation-intensive services. To address this problem, IoT services have envisaged a centralized cloud-enabled IoT framework modeled as a black box facilitating resilience, adaptability, reliability, trust, confidentiality, and integrity, reducing maintenance costs, and enabling time-efficient IoT application support. Blockchain technology stands out to be one of the most suitable candidates for enabling a secure and distributed IoT ecosystem, thereby adding a helping hand in countering these inherent challenges and issues. Blockchain technology is a conglomerate of cryptography, public key infrastructure, and economic modeling to induce distributed database synchronization in peer-to-peer networking supported by a decentralized consensus. The underlying features of decentralized architecture, immutability, verifiability, and fault-resistance make it suitable for envisaging a properly coordinated and distributed IoT environment, giving rise to a Blockchain for Internet of Things (BCoT).KeywordsBlockchainInternet of Things (IoT)BCoTIndustry 4.0
