  • Chapter
  • First Online:

Part of the book series: Palgrave Studies in Financial Services Technology ((FST))

Abstract

This chapter explores the advent of blockchain technology which is the basis for almost all of the many types and formats of virtual currencies. We review the types, uses, and the many ways in which blockchain is transforming the world of business as well as society. Among them are management tools, financial services, tourism, legal and accounting services, and the innumerable other uses due to blockchain’s impenetrability to hacking, its protection of privacy, and many other advantages afforded.
