Blockchain Technology Explained Certificate
This programme explains how blockchain systems actually work, from cryptographic hashing and digital signatures through consensus rules, smart contracts and token standards, for people who need to understand the technology rather than speculate on it. The material is written for a non-programming audience: every mechanism is explained in plain language first, then traced through a real transaction on a public block explorer. It ends where most introductions do not — with the trade-offs, the failure modes and a decision checklist for when an ordinary database is the better answer.
