With NxtT Transparent Forging, the network can detect which accounts don't participate in the proof-of-stake block verification process and temporarily penalize them.

Nxt Transparent Forging which will allow Nxt to approach Visa/Mastercard rates of transactions. This is possible with Nxt because the transparency provided in the protocol will allow each user's client to determine which node will generate the next block. Other nodes can then send their transactions directly to that node. This also allows additional fees to be realized for immediate, priority transactions. An equally important feature of Nxt Transparent Forging is a security mechanism to prevent forked chains from being forged by high-stake nodes. This prevents against even a 90% majority owner of all Nxt branching out and forcing a fork.
