The CENTUO Pool (ticker CENTU) has not generated any block in the last two epochs. I have attached the screenshot of status of the producer node. Is this normal with nearly 800k ADA in stake? Am I doing anything wrong in the pool configuration? I can see that the missed slot leader checks are minimal and acceptable, any suggestion what might be happening? Thank you ).
I’ve seen 4 consecutive epochs without blocks with more than 1M delegation, that’s very possible to happen in your case.
You should check if you have slots assigned to mint blocks every epoch, to be 100% sure it is just bad luck and not a real problem.
Finally, after 6 epochs I can see that a block was assigned to be minted by my pool but apparently this block was minted by another pool with much higher stake (with around 60 millions ada!). I understand that the protocol selects the pool with lower stake when two pools are selected to mint the same block, correct me if I am wrong, is that normal this is happening to our pool? It seems we have extremely bad luck considering we have nearly 800k ada in stake.
Prior to the recent Vasil upgrade, “fork battles” were decided based on preferring the block with lower “leadership VRF” value. This did preference the smaller stake pool because they needed to get a lower leadership VRF in order to be a slot leader in the first place. So it was more likely the small pool would have a lower “leadership VRF” than the big pool.
However, after the Vasil upgrade this was changed to what people are calling the “block VRF”. This VRF result is based only on the following values:
This “block VRF” is deterministic and not based on the transactions in the block so it cannot be gamed. Choosing the winner based on lower “block VRF” produces a randomised outcome. In other words, now each contender has an equal chance of winning the “fork battle”. It doesn’t matter if your stake pool is big or small.
I totally agree with you, it is harder now for small pools to mint new blocks. The Cardano community should suggest improvements to help small and non-saturated pools! I hope Cardano core developers treat this as a bug and fix it. Otherwise, this could negatively impact the pools decentralisation.
