I've been wondering recently what's ahead for us in terms of the evolution of digital currencies.

There has been a lot of amazing development with blockchain and cryptocurrencies in general in the past decade. But I wonder if there's anyone working on other ideas or technologies that could also be promising. I'm not talking about altcoins. I mean real breakthrough ideas, similar to what happened when Bitcoin was originally introduced. It would be really exciting to witness the birth of something completely new in the next years/decades. I'm sure we have other brilliant "Satoshis" out there.

I'd love to learn more about cool projects and concepts that could be the evolution of blockchain (again, not altcoins please  )
