Recent innovations have created signifi cant developments in data storage and management. These new technologies now allow for greater security in databases and other applications. Decentralized Computing Using Blockchain Technologies and Smart Contracts: Emerging Research and Opportunities is a concise and informative source of academic research on the latest developments in Blockchain innovation and their application in contractual agreements. Highlighting pivotal discussions on topics such as cryptography, programming techniques, and decentralized computing, this book is an ideal publication for researchers, academics, professionals, students, and practitioners seeking content on utilizing Blockchains with smart contracts.

With the advances happening in the area of urbanization, with increased demand for dwellings and an increased number of vehicles on road, finding a parking spot has become one of the major pain points for the citizens. This is mainly due to the limited parking spaces available and difficulty in finding a vacant lot during busy hours. To overcome this limitation, one solution is to create smart parking spaces which are rather easier to find and use. In this work, we propose a Blockchain based solution where parking pools can be created by developing a transparent platform where individuals can rent out their unused land for a stipulated amount of time. A non-fungible token system representing unique parking lots will be created for transparency of the entire system. This also has the added advantage of generating revenue from their otherwise unused property. Smart contracts over Blockchain enforce the contractual agreement between the participants ensuring financial transparency in the proposed system.

Tracing the vaccines from the manufacturing labs till the health centres administering doses to child is a cumbersome process with the involvement of large number of stakeholders and with multiple levels of book-keeping mechanisms. This work primarily focusses on the problem of traceability of immunization vaccines from manufacturing facility, through the distribution mechanisms in cold storage network and the vaccine handling/administration facilities, till the end consumer in the Indian context. The proposed research named, Immunochain is a state-of-the-art big data and block chain technologies powered, mobile/web enabled vaccine traceability solution for immunization programs in India. It is vendor neutral, scalable, replicable and reusable across different immunization programs in any geographical context. Experiments and pilot testing on Indian geography indicates that the proposed approach outperforms some of the existing approaches in vaccine traceability and record management systems.
