I don't know if it is working or not, but the last net hashrate was 144 MH/s and difficulty was way up. The pool currently only has 3 MH/s on it, so it would take days to find a block with that hashrate. In order to know if it is working or not more hashing power needs to be used and then we will know whether or not it is working as intended.
The Net Hashrate (shown in the wallet) is "stable" at 144.000 MH/s for a few days. I dont think, that this ist right.
As seen on
http://espv2.miningalts.com/ there are no new POW blocks (5000 ESP reward)
144 MH/s was the last hashrate that was recorded before POW stopped working due to the 8.5.0 patch 6 update. Since it cannot change until a new block is found that is what we are currently stuck on until we solve more blocks. If all is working correctly, a block will be found (after a while if the pools hashrate doesn't go up or individuals don't solo mine with significant hashing power) and the difficulty will readjust as well as the current hashrate displayed in the wallet. These changes only happen when blocks are solved by POW.
