There was a time, not long ago, when the word "decentralization" carried the glow of a radical new dawn. In the early 2010s, Bitcoin lived mostly in the shadows. Electrum wallet appeared as one of the first attempts to make storage feel less like an arcane Linux experiment and more like a user-facing product. USB ASICs started humming in the basements of curious engineers. A few conferences in dimly lit halls hosted fiery talks by Andreas Antonopoulos, who thundered about a world where Bitcoin would be used for "everything." Pay for your coffee with Bitcoin, he proclaimed, as if it was inevitable that a skeptical barista and a cautious government regulator would happily comply. The problem was obvious. No one knew who was supposed to allow such transactions, or why the average citizen with a salary paid into a SWIFT-linked bank account would ever need an alternative.
