I read it the same way as achimsmile, I think a comma/fullstop/words were missing in your rush

"Around 20% would be quite a lot, or if I may say, with the current total amount of stake forging
. So around 23% of stake would give you a shot at a 51% attack
as there is about 45% of the stake forging at the moment."
I think ^ is what you meant. But it read as though only 23% of people were forging.
Isn't this more or less exactly what's expected? You need around half of the total staking power to attack?
Yes, that's it.
Some simple questions about nxt so I don't have to look them up:
1) Is transparent forging really implemented? I thought not
2) Is
https://bitbucket.org/JeanLucPicard/nxt the latest source code? if not, where do I find it? do I really have to decompile Java?
3) If account A transfers some amount to account B (which was already verified) at block N, can B use that stake to forge block N+1? if not, when will it become part of B's effective balance?
4) Is re-leasing possible? if A leases to B, can B re-lease to C without approval from A?
5) which is the best place to ask these questions? nxtforums? which section?
Thanks!
