Node churn is actually a big problem, especially if disqualifications are frequent during GE.
Alexey did a breakdown of what it costs them to repair data when a node gets disqualified and it’s astronomical !!
I’m actually worried that it might cause BIG problems if many nodes exit the network (not gracefully) in a short period of time. I really hope that they are actively working on a solution (should be one of the top priorities) because at the moment the held amount only covers a fraction of the repair cost.
There is a mention about repair being distributed across the nodes in the whitepaper but I guess that they haven’t gotten around to it yet. That would greatly increase the decentralization of the network as well as reduce the cost of rented servers.
Anyway that’s just my 2 cents on what Storj should work on next. I think @SGC infected me with the “long post with lots of digressions” virus haha
