As was the case for the internet in the nineties, blockchain is at the dawn of the Blockchain age. This technology will disrupt existing business models and give birth to new models. It will inspire the emergence of community economies built on a blockchain network, where every participant makes contributions to, and receives benefits from, the community. There is no longer a single entity that controls and receives dividends from the economy.
In this chapter, we have discussed use cases across industries to give you a flavor of potential blockchain applications. Given the limitations of the existing technology, not all these cases can be immediately implemented. As the technology progresses, more use cases can be tackled. Finally, we talked about important factors to be considered in selecting a proper use case and the steps to be followed in developing a complete DApp through an in-depth discussion on the healthcare data sharing use case.
