So obviously I am not solo mining bitcoin but I think the underlying principles are the same so you guys could help me out here.

I am solo mining ergo on a solo pool (herominers solo pool)

What I do not understand exactly is what share difficulty is (not to be mistaken with ergo network difficulty which I understand)

I mean I hash with 2GH/s on ergo I am able to switch between varying share difficulty/vardif(which I have noticed goes up to like 80GH difficulty) or choose a constant share difficulty.

What I noticed is that if I set that difficulty to 8GH I get more solo valid shares...

But does this mean that the probability of me finding a block decreases because finding a block needs a higher GH share or something like that ?

I assume that the greater the share difficulty the longer the hash I have to process (so maybe the better changes to solving a correct block? )

Could you explain in detail what share difficulty is and maybe advise me if I should use varying difficulty in my case or a constant (and at which value? ) ?

    Shares are only defined as concept in relation between your hasher and your pool. It has no relation on the probability of your pool as a whole to mine a block; that is controlled by the difficulty. – Pieter Wuille Jun 01 '21 at 21:24
  • @PieterWuille yes but I am solo mining in a solo pool (sounds bizzar I know but it exists) we dont share the blocks we find in other words. The thing is though that manipulating share difficulty I essentially manipulate how many valid shares I submit but how does this affect my chances of finding a block? E.g at 8GH I submit many more shares compared to at e.g 54GH which means many more chances (like submitting more lottery tickets) but does that maybe mean that because its a smaller hash (8GH) the chance of "getting it right" or find a block decreases? – papajo Jun 01 '21 at 22:13

    It has absolutely nothing to do with your probability of finding a block. It only changes how accurate the pool's idea of your hashrate (and thus affects your share of payout in case it finds something) is. – Pieter Wuille Jun 01 '21 at 23:02
