This Hot Report explains what Blockchain or Distributed Ledger Technology is, and what it isn’t. It explains why the technology is tamper proof and therefore immutable. It shows that Blockchain is not some new technology in search of a problem, because it addresses a key issue at the heart of all commerce and trade. Trust. It discusses how and why it works, how the technology is not a complete replacement for existing database technology, transaction processing or messaging systems, but will always sit alongside, connect to and work with those technologies. We show real-world examples of why you should care, and recommend that you make sure your internal resources are blockchain literate, if they aren’t already. Our recommendation is to ignore the hype, skill up and start planning it into your technology strategy now.
