Did the whole Lethean network just die? My local daemon shows the total network hashrate as 620 H/s. I thought it's a problem on my side, went to check other larger pools and they're all dead - no one seems to be finding any blocks. Shocked

What's going on? I'm stuck at 296645. The official pool is somewhat close as well. And hashvault.pro is at 298288. Did the chain split?

Tonight, over the course of several hundred blocks, it would appear some manipulation occurred to drop difficulty and make a bunch of low difficulty (essentially "free") blocks. We are looking into the issue to determine the exact cause. At this time it is unknown how the exploit occurred. The good news is that daemons are automatically properly re-syncing back to the main chain before any of the block manipulation started (block 296225). However, any daemon mining blocks (eg. pool daemons) will require a restart before they will work correctly. To that end, Venthos and I have restarted our pool daemons and are attempting to get the network moving again. I am off to bed now but will resume analysis of the issue first thing in the morning to figure out what went wrong and ensure the issue does not recur. I will update you as we know more.

I think you should do not process rollback. XDN and LOKI have some errors but they never process rollback, because miners must payout electric bill and sometimes it is a gift for miners.
