      But you also know that it isn't going to happen in BTC. And without appcoins, where?

      why not aim for a side chain first? Not opposed to a separate coin btw.

      Great. Is all the functionality present now in Bitcoin Core? How do I compensate miners? Engineers?

      are there major non-political obstacles to side chains? I got the impression that it was mainly being held up

      Last I checked - a few months back - it was just a bunch of ideas. No code on main.

          And more importantly, no schedule on when it was going to go live. You can't build something that doesn't exist.

          And even when you got the code, nobody ever answered the problem of how you pay miners and devs.

          I'm happy to admit appcoins answer that problem. But then again, fraud also answers that problem...

          Yes. Which is why we're being stupidly careful not to defraud anyone!

          Not creating a new coin is the gold standard there. Sometimes there's no alternative, but it is a big risk.

          Like I said. Not creating a new coin makes deploying new protocol-level features very very hard to do.

          Anyway, this convo will go in circles without a better understanding of what the alternatives are. :)

          Write that blog post. Then I will write back. Or vice versa.
