Blockchain technology is one of the most sensational and under rated technology in current technological and financial sector. The great wave in blockchain technology for the banking sector is still unexplored to its depth, as the need for new technology in all the areas of life is a necessity nowadays. The study was conducted to identify different services that the financial sector can provide to its customer by accepting a unified blockchain technology. The fundamental inkling of blockchain technology is, its public and the same is shared in a tamperproof ledger which allows the heterogenous community to share the sensitive data over a distributed ledger. This paper gives an idea about how this tamperproof technology can be used to increase the efficiency, transparency and to lower the risk and expenditure associated with the highly sophisticated data of an individual in relation to banking sector. The technology has great potential to overcome the disadvantages of the current central server system in banking industry, which is highly prone to hacking and cracking. The blockchain technology is current meant to be a hack proof system which is still in its initial stage of development. As the technology is still in pilot testing stage on banking sector, once the same is found feasible to with stand the current market need, this will bring an economic and technological boom to different sectors. The most exciting premises about blockchain technology is, it makes banks pointless. Though, this paper contends that the advantages of block chain technology will be used by the financial institutions in a first mover place rather becoming outdated. [ABSTRACT FROM AUTHOR]

Healthcare is a service that provides healthcare services to patients with blockchain technology. Blockchain technology is an emerging technology that enables for the communication between patients and medical experts to take place over the internet. It enables the healthcare unit to exploit trustworthy data rapidly and easily, either simultaneously or simultaneously with other tasks. In this paper, we have developed a strategy that makes use of the possibilities provided by blockchain technology to ensure the privacy and security of patient data. The proposed strategy uses a blockchain that is available to all nodes, and it can determine whether a certain node can be trusted. It is possible for a patient to be open to the notion of switching their primary care physician and commencing therapy with another user. This is done by collecting the data from a wide variety of IoT devices, and this information may then be transmitted over fog and edge computing gateways. This information may be used by the gateway, which is the component that establishes a connection to the cloud computing service. We have constructed a test bed to evaluate the process of smart contract sharing between two peer nodes. It has been proposed that each of these nodes should have their very own specialised test beds to make the most out of it. [ABSTRACT FROM AUTHOR]

The Internet of Things (IoT) is a cutting-edge technology that enables virtual and physical objects to connect and communicate, resulting in new digitized services that enhance our quality of life. Despite its many advantages, the current centralized architecture of IoT poses various challenges such as single point of failure, security concerns, privacy issues, lack of transparency, and data integrity problems. These obstacles hinder the future progress of IoT applications. Moving the IoT to one of the decentralized technologies is the right solution to these issues. Blockchain is considered as the most common and popular decentralized technology. It is a new technology that operates with a decentralized, distributed, public, and real-time ledger to store transactions between IoT nodes. The main focus of this paper is on utilizing Blockchain technology for the IoT, specifically showcasing how different features of Blockchain can be utilized as a service in various IoT applications. The increasing penetration of Blockchain and IoT in various companies and industries primarily enables secure storage of large amounts of sensitive data, which can grow at a tremendous pace for the global IoT Blockchain market.
