Misc. technical questions

[ferrerabertran]

Hi there,
I have been interested in MimbleWimble and Grin for a while now. After reading a lot I am left with a couple of questions that I’d like to clarify:

• Is the claim that transactions/sec would be worse than Bitcoin still valid after all current optimizations (Bulletproofs, etc)? https://lists.launchpad.net/mimblewimble/msg00235.html
• Is there a way to have auditability like in Monero and if so how would it work? (http://i.imgur.com/gQlj9Oy.png)
• Did I understand it correctly that atomic swaps with Bitcoin would only work when Bitcoin implement Schnorr signatures?

Thanks in advance.

1. Optimizations sure make things better. Note that your link does not claim throughput would be worse than bitcoin at all, just that 2000 txs/sec is unrealistic (which is still true).
2. There are ways to do something along those lines, yes (sorry for being elusive, that image is fairly high-level as well).
3. No, Schnorr on the bitcoin side isn’t required. Atomic swaps rely on secret sharing which can be done on both chains, albeit with different mechanisms.
