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
The part that allows you to predict the next block is, you should be able to confirm this yourself using the tool above. TF is several interlocking bits so you can't really pick a point and say "that's when TF began". And not all of it is implemented yet.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?
I believe so. Every version ships with the source code in the 'src' folder so you could use that for the latest version. Not sure it is in as usable format though3) 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?
You have to wait for N+1440 blocks before it counts in B's effective balance again. You can't broadcast a transaction, move the Nxt, broadcast again in the next block in a new account, move, broadcast move etc. using the same NXT. 4) Is re-leasing possible? if A leases to B, can B re-lease to C without approval from A?
No5) which is the best place to ask these questions? nxtforums? which section?
Nxtforum is best.
