The last couple of years have witnessed the rise of Distributed Ledger Technology, in particular the Blockchain technology. It is envisioned to unlock the doors to the decentralized future by overcoming the well-known impediments of centralized systems. Powered by the underlying cryptographic techniques and technologies like P2P networking, it offers numerous outstanding features like disintermediation, immutability, non-repudiation, and proof of provenance, integrity, and pseudonymity. Smart contract is considered as vital technological concept that enhances the capability of blockchain-enabled system and provides automation and trust. In simple words, smart contract is a piece of software program that aims to codify the terms and agreement of a contract between multiple parties. Thus, it is a softwarized contract.

Although cryptocurrency has been a popular use case of blockchain technology, however, it has found to be of immense potential for other domains and sectors like healthcare, robotics, public governance, and supply chain management. Next generation of mobile networks ecosystem is another area which is envisioned to significantly leverage blockchain technology.
