max reorg depth in NXT is 720 blocks

Checkpoints are centralization.
Mex reorg depth isn't checkpoints.

It is if you expect it to be honored objectively by offline nodes (propagation isn't objective proof because it can be Sybil attacked). I will let monsterer explain that to you, if you don't understand.

May be you will explain us what exactly is centralised in a cryptocurrency (doesn't matter PoS or PoW) whose nodes reject reorgs if they are deeper than the max allowed depth?

Maybe first you can explain why you are too ignorant to understand what I wrote which thus makes your reply irrelevant noise.

Hint: how can an offline node reject that which it wasn't online to detect? How does an offline know from the history which is presented to it, which chain (past the 720 limit) occurred first? Basic things you need to grasp before you post on this thread. An offline node is ignorant about the propagation order that occurred which the online nodes observed. Those who claim they were online, can be a Sybil attack lie. The only proof is what can be cryptographically stored in the block chain history. I so tired of replying to those who don't know a damn thing about what they are writing about yet are so damn boastful.
