But why has the blockchain stalled since the fork? that would suggest that many of the wallets MUST be on the same chain as Epiphany and it has messed up the difficulty.
Not necessarily!
I think it might just be bad luck since we haven't given the POST algorithm enough time to ''split up''all the coins.
My largest address for example is still receiving 2 SLR interest payments. Once all of the coins split up and mature I guess wo won't see the blockchain stalling anymore. but i'm no expert that's just a theory
Yes, you are right, that's what Steve has been saying, and that's completely logical.
What has been bothering me though (and still does) is that the only thing the system can do to compensate for all these luck/no luck scenarios is to use the built in feedback mechanism for self-adjustment - and it's not doing it!
If you look at the Difficulty column here:
https://chainz.cryptoid.info/slr/and see how it is changing according to the block rate.... Or is it even changing at all? And that IS the only mechanism the algo has to selfadjust to try to meet the target blockrate, at all times, wallets number, coins split up or not, etc.
I will keep insisting that Difficulty MUST go down on its own when block rate decreases like now, for no matter what reason, and Difficulty MUST go up when block rate increases to let's say 2-3 blocks/minute, for no matter what reason.
