I noticed Vault 3 contains a huge performance improvement over Vault 2. That makes the low energy consumption of Bullion now extremely low!
Keep up the good work and make sure this is advertised when Vault 3 is released.
Yes, the new Vault 3.0.0 is compiled from completely redesigned code; in order to allow the new multi-tier reward approach of BPN masternodes, along with clearing some lingering issues of Vault 2.4.x, it was necessary to follow a completely new approach.
I am glad you are noticing how different the Vault 3.0.0 is!
