Some strange claims in this document
"Nxt transactions don’t have locking and unlocking scripts. Instead, the Nxt protocol uses accounts to encode a sender and a recipient of a transaction. This restriction severely limits the
capabilities of the system to handle smart contracts compared to Bitcoin."

Etherium also uses user accounts to the best of my knowledge and handles smart contracts ...

Also would be nice if someone review the various "attack" scenarios and explain how NXT protects against them.

Yes, the statement about smart contracts capabilities sounds weird. There are some more glitches in the paper(e.g. about Tendermint, I spent some time digging around it).

About attacks investigation with simulations, see https://bitcointalk.org/index.php?topic=897488.msg10152632#msg10152632 .

Unfortunately, there's no much progress from us and around since then  :'(

Some things might not be exactly right in the article but it's still one of the best review articles about the problem I've seen

"This means a user with a single big stake is at an advantage: his percentage of blocks is strictly higher
than his stake in the system (see Fig. 2). Therefore, Nxt is not a fair system"

it is a very small percentage and it resists sybil attacks. if it were the other way, advantage to bot writers who split up accounts in to many smaller accounts, that seems less fair and less secure

Nope, I'm working on this stuff, but things are going sloow :( (especially when there are a lot of other things to do, and producing material for peer-reviewed journals is a process consumes a lot of time)
