Yes probably. It should probably be slowed down some when we do a hard fork for other things like MRL-0004. The one minute block time was one of those things that TFT did anyway despite everyone else disagreeing. It was never intended that way (except by him, for god knows what reason).
good idea.
are there any discussions / opinions about what may be a good blockrate?
(i assume you'll keep the social contract intact. eg 2min blocks - doubled reward)
Maybe 2, maybe 4. There was one view that it should be >5 (I don't disagree in the abstract) but 8 seems a bit high. Yes about the social contract and that's what makes anything that isn't a power of two a bit tricker to stick with the same curve (but not impossible). With power-of-two it is trivial.
4 min should be OK. At present, there are not much transactions going on with XMR. Most of the blocks are mining rewards only. When XMR gets used more in the future, we can reduce the block time to 2 min, then 1 min, even 30s when internet is much faster resulting fewer orphan blocks.
