Before relaunch: nPoB 3371 nPoW 12023 nPoS 40 (all blocks < 15935)
After relaunch: nPoB 317 nPoW 1210 nPoS 3129 (all blocks > 15935 and < 20600)
As you can see, the ratio between PoB and PoW blocks before the relaunch is .2803 or about 1 : 4
The ratio between PoB and PoW blocks after the relaunch is 0.2619 or about 1 : 4
There is no change in the number of PoB blocks being found in respect to the number of PoW blocks. There is however, a lot more PoS blocks being found (3129 compared to 40).
That means that the amount of time to find 1 PoW block is larger, that is there by design. I may change the minimum difficulty for PoS blocks to make them harder to find, making the PoW blocks found more often and thus the PoB blocks more often.
Please do increase the minimum PoS difficulty, or increase the minimum PoS mint value (if possible), most of these blocks have a very low mint value anyway.
