We are aware of about 20-30% hashrate on some unaccounted pools. We knew this because when we were trying to notify our pools to hard fork, we couldn't find these guys.

Btw, we are aware of some of the concerns of miners that our hashrate is being dominated by botnets. Ocminer from Suprnova mentioned that previously there were some schools etc who complained to him and he identified them from many small hashrates. He does have a point.

I spoke to miningpoolhub on this and he mentioned that this could be CPU miners as well and he brought up that on other coins, there are single entities with much bigger hashing power as well.

So, both sides have valid points.

Regardless of this, MTP is now an absolute priority and coding is well underway. We will post updates as soon as they are available and a more accurate timeframe can be estimated but tentatively should be by the end of Q2 2018 and hence we won't be doing a another transition algorithm since it's not that far off.

We previously had some concerns of pool software as none of our coders are experienced pool coders but we believe that even if we have to launch with solo mining to start with and then organizing a bounty for an open sourced nomp or yiimp pool for MTP, this would be acceptable. A period of solo mining isn't bad and is true decentralization.
