PoI is definitely a way forward. Does NEM have transparent forging?
Does anyone have transparent forging?
TF = DDoS nodes and destroy the network.
@Makoto, regarding DDoS - no, I still think TF is possible, but I doubt it makes sense for poi:
TF - rather not (it might make sense in PoS, but not that much in PoI, also, is there any coin/system running that has WORKING TF?)
Account Leasing - actually power leasing not account leasing - it'll have something that we believe will be much more interesting, but we don't want to spread the details yet
Alias System - we were discussing it, and we did'n find good reason to have it (also we are thinking about something that might be more general)
