Understanding Blockchain

A working, non technical grounding in what a blockchain actually is, what it does well, and the far larger set of problems it does not solve. Delegates learn how a distributed ledger reaches agreement without a central authority, what a consensus mechanism costs in energy and speed, how public and permissioned networks differ, and where a conventional database would be the better answer. The course deliberately spends as much time on failure and limitation as on capability, because the commonest expensive mistake in this field is adopting the technology for a problem that did not need it. Delegates leave able to interrogate a blockchain proposal rather than take it on trust.

Course objectives

  • Explain what a distributed ledger is and how a network agrees on its contents
  • Compare the main consensus mechanisms and the trade-offs each makes
  • Distinguish public, private and permissioned networks and their governance implications
  • Identify the characteristics of a problem that genuinely suits a blockchain
  • Recognise where a conventional database is the cheaper and better answer
  • Interrogate a vendor proposal and test the claims made for it

Who should attend

  • Managers and executives assessing blockchain proposals
  • Business analysts and project managers
  • Risk, audit and compliance professionals
  • Public sector officials evaluating digital initiatives
  • Anyone needing a grounded view of the technology without the marketing
