The Byzantine Generals’ Problem has to do with agreement. The illustrative story tells of a group of commanding generals who encircle a city and have to formulate an attack plan. There are two options: attack or retreat, and the generals need to come to a consensus decision in order to make the plan effective. Further complicating matters, having surrounded the city, the generals are geographically distant from one another and to communicate their decision to the others, they have to rely on a messenger. A messenger who might take the fastest route through the city center to the other side might be efficient, but there would be no way of knowing if their message had been tampered with: Were they bribed at the gate? What if the messenger never arrives? (via https://technosphere-magazine.hkw.de/p/The-Byzantine-Generalization-Problem-Subtle-Strategy-in-the-Context-of-Blockchain-Governance-8UNNcM8VShTpBGWRuob1GP )
