Here’s an understandable explanation for the appeal of bitcoin. From Nick Giambruno at internationalman.com:
Imagine you are in charge of a medieval army storming a walled city.
The attackers and defenders are equal in strength.
The only way the attackers can win is if all the generals successfully coordinate their attack. If even one fails to coordinate, the entire attack will fail.
Complicating matters is the fact there might be some spies among your generals who deliberately pass on false information to sabotage the attack.
The problem is, how do you get them all to coordinate the attack successfully?
This is what is known as the Byzantine Generals Problem. It was a longstanding problem in computer science.
In short, it’s the problem of getting different people—who may be hostile to each other—to come to a consensus about something without a trusted arbitrator of truth.
Before Bitcoin, this was not possible.
Obtaining consensus required a centralized party.
Imagine you are a shameless bitcoin pumper trying to get people to accept digital currencies so they will learn to accept CBDC’s
