I've always found it fascinating to trace back to the roots of what we now call crypto. Nick Szabo, who is best known as the father of smart contracts, actually provided an interesting retrospective on this history during a Bitcoin conference in 2021.

What struck me is that he showed how, as early as 1995, there were already serious discussions around decentralized concepts. Nick Szabo talked about virtual banks, distributed networks... ideas that seemed completely outlandish at the time. And in the same year, Szabo formalized the concept of smart contracts.

But even before that, there were other pioneers. David Chaum's DigiCash, for example, with its blind signatures that really reduced the need for trust. Chaum also created Cyberbucks, which can be considered the first true private digital currency. That’s real early-stage work.

What Nick Szabo also emphasized is the role of his Libtech mailing list. It was a space where ideas circulated, where people exchanged concepts like Bit Gold, b-money, RPOW. Projects that never really took off at the time but laid the conceptual foundations for everything that followed. Bitcoin didn’t emerge out of nowhere; it was the convergence of all these earlier reflections.

Looking back at all this, we realize that Nick Szabo and a few others really prepared the ground. It’s a good reminder of how technological innovations develop gradually, through the accumulation of ideas and experiments.
