Have I missed something? Why is the difficulty jumped so high?
We keep popping up at number one on Coinwarz, that could explain it. We've also been added to two new exchanges, so pretty good day in regards publicity
[edit] the networkhashrate has jumped up from 1.7gh/s to over 6gh/s so that's why the diff is up
dont forget that PoS blocks are included in difficulty calculation, network hashrate is actually inferred from difficulty, not he other way around.
might be allot of wallets generating PoS blocks right now
My wallet doesn`t do nothing

look at your incoming transactions and outgoing transactions
match the outgoing ones to the earliest incoming transactions, those left unconsumed are the ones you will see PoS soonest from.
ex: ordered by least recent to most recent
in 11111
in 22222
in 5000000
in 300000
out 25000
in 666666
the out transaction would consume the 2nd and 1st TXO
the wallet tries to make the smallest possible transactions in size, so the least possible inputs will be included
but it also prioritizes base on FIFO
