Virtual money systems known as cryptocurrency function through a vast network of databases called blockchain. As the technology evolves, cryptocurrencies will be used by growing numbers of businesses, industries and governments, say experts such as Fulton Schools Associate Research Professor Dragan Boscovic. He is the technical director for Arizona State University’s Center for Assured and Scalable Data Engineering, known as CASCADE, where researchers are working with the cryptocurrency company Dash to make blockchain more secure and more energy efficient in its use of the computing power it requires. Such progress will help make use of blockchain more mainstream, Boscovic says.
