Blockchain, which comprises of ‘blocks’ of transactions, is one of the most well-known uses of DLT and underlies the cryptocurrency Bitcoin. DLT has received growing attention in recent years as an innovative method of storing and updating data within and between organizations. </div> <div> The lecture will cover the initial emergence of blockchain as infrastructure as a solution to the problem of digital cash. Blockchain allows the automation of cross-border payments over the Internet regardless of geographical constraints. This contrasts with conventional financial transfers that can take days between different banks, especially when they operate in different countries. The openness of blockchain technology and its foundations in the Internet make it inherently global. The potential for blockchain extends beyond cryptocurrency, allowing traceable digital tokens representing physical or digital assets. This expands the theoretical range of application of blockchain technology to many business problems in almost any industry and sectors, including financial applications, supply chain, Internet of Things (IoT), etc. Beyond applications in finance and banking, new applications are emerging in supply chain management, manufacturing, agricultural product tracking, advertising verification, IoT, healthcare and the pharmaceutical industry, among others. Besides, the lecture would have a comprehensive details about types, features and working of Blockchain. </div> <div> <br /> </div> </div> <div class="row lecture__section"> <h2>About this
