To be clear, I wasn't trying to offend any altcoin  I was just trying to protect the topic because I could already see people coming here to shill their coins, saying they are the "Bitcoin killer". I was just trying to keep the topic on a good level.

I had originally posted this topic on "Bitcoin discussion" but it was moved here 


I agree. But when quantum computing goes mainstream in the future, won’t this pose a threat to the current security behind crypto?



But thanks all for your interesting point of view and links. I’ll be checking them out!



One thing that worries me about the blockchain is how it will be used by governments to track transactions and tax people. We are already seeing this in the US, where the IRS is investing billions of dollars to track profits. The ledger allows them to go back to any time in the past and go after people for any reason they choose. I see this as a vulnerability of the system. I hope someone will come up with a digital currency that doesn’t rely on a blockchain and can act more as a p2p transaction. But I know this might be impossible to solve without running into the double spending issue.

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  )
