I have a question for the developers. How many masternodes is necessary for a stable network operation?
It could work fine without a single masternode, so long as there are at least some nodes that accept incoming connections. For the SwiftTX feature, minimum of 6 MNs are required.
I'd say the network needs a minimum of 2 honest nodes in different locations that accept incoming connections from everyone in order to be stable. BTC2 has hundreds of them.
