Hello Mr Kano, are these two block the result of luck or the consequence of your last software upgrading?
have you thought about publishing the node's software changelog?
The changes are nothing to do with bitcoind. My explanation made that clear.
Until we have a run of a dozen or so blocks without ridiculous bad luck, I don't consider the problem solved.
I'll also be getting access to more data to analyse soon to decide if there are problems in the code before I changed it.
As I said before, I'm looking into this in as many ways as possible, to verify if there is a reason, under our control, that caused it.
