Who is this presentation for?

  • Architects, technical leads, and CTOs

Prerequisite knowledge

  • A basic understanding of computer science, especially hashing
  • Familiarity with distributed systems (useful but not required)

What you'll learn

  • Understand what a blockchain is at a technical level
  • Learn the basic types of blockchains and when they are (and aren't) appropriate


In 2017, blockchains have definitely gone mainstream. Every major vendor and consulting firm seems to be offering blockchain solutions to business problems. However, a large amount of the coverage is still driven by vaporware and a certain measure of hype. How can architects move beyond the noise to determine whether a blockchain is actually useful for their projects?

Join Ben Evans to learn the basic technology underlying the blockchain, explore real use cases, and find out how to avoid antipatterns.

Topics include:

  • Distributed ledger basics
  • Smart contracts
  • ICOs
  • Common pitfalls and dangers
  • Positive use cases
  • Alternatives to the blockchain

Hi Ben,
thanks for sharing your knowledge during the conference. I couldn’t attend your session and was wondering if you will be posting your slides to be used as reference later?
Thanks in advance for posting,
