...or just make it scarce enough! Higher difficulty + PoS after 3 months would fix it... Would also give us 3 more months to think about a new fix...
It does not fix the problem of quantity of transaction into wallets..... I mean dust coins
CPU itilization problem is triggered when there are hundreds of small PoS transactions. That wont happen if you increase PoS diff.
I think it is not only small POS transaction but also POW dust received from pools. I have that kind of dust into my wallet, I am sure you have as well (may be bigger dust ).
My pool dust is not causing any cpu spikes whatsoever. I only had spikes when my wallet was minting PoS blocks. The second i encrypted the wallet cpu spikes dissapeared. I fixed the problem by moving all coins to a new wallet.
