Care to explain how a hard coded rewrite limit (you stated 720 for NXT) sacrifices decentralization ? What has one todo with the other ?
I'm assuming you're refering to this
New users who encounter multiple histories are no longer able to
distinguish them on their own; they need to ask existing participants in the network (which may
include friends and family, large corporate entities with reputations to maintain, public websites,
etc.) which history they know to be the true one. This is not a distributed consensus! It is a different
sort of consensus, which may be formed amongst always-online peers in a decentralized way, but
10
depends on trust for new users and temporarily offline ones. It is correspondingly vulnurable to
legal pressure, attacks on trusted entities, and network attacks.
?
This makes no sense to me. I'm no expert but if having to trust existing peers is a bad thing then were are new peers supposed to get the chain from if not from existing peers ?
Also I'm not even sure the assumption behind this criticism is accurate. I believe there are ways for nodes to calculate which chain is "better" (in BTC it's simply the longer chain afaik). There are score systems for that in place. I believe both NXT and NEM have something like that so every peer can determine on it's own which "history" is better.
