gLiveView has OP Cert Disk disk|node|chain 2 | 2 |?

What I meant above was zero blocks in total, not zero transactions in some blocks.

Ah, okay. Still, your allegation

@andrejpodzimek

However, it does look like many pools “circumvent” the problem by creating empty blocks (with zero transactions). Sure, they earn nothing by doing so (?) — unless the fixed block fee still applies —, but what they do gain is visibility.

does not make much sense. It is totally okay to mint a block with 0 transactions if the mempool is empty at the time. That is not “circumventing” anything at all.

@andrejpodzimek

That said, this time I was lucky to catch what appeared in the logs at the time of a failed block “adoption”

For only 30k stake, you get quite a lot of blocks assigned.

@andrejpodzimek

Without an intimate knowledge of the codebase this looks hard to interpret…

(WrapValidationErr {unwrapValidationErr = CounterOverIncrementedOCERT 0 12}) is not that hard to guess. Alternatively, a quick search on this forum for “CounterOverIncrementedOCERT” gives for example https://forum.cardano.org/t/not-getting-the-vasil-node-counter-memo-a-story-for-other-spos/111937 and https://forum.cardano.org/t/failed-adoption-over-incremented-during-re-certification-i-think/124943: Your certificate number is invalid! It must not be more than 1 greater than the on-chain certificate number (or 0 if there never was a block minted). Yours is 12 according to that error message.

This is also described in https://www.coincashew.com/coins/overview-ada/guide-how-to-build-a-haskell-stakepool-node/part-iv-administration/issuing-new-opcert#determining-the-counter-value which was already linked to above in:

@bertman

Also be sure your node.cert is valid when turning KES.

All in all I’m becoming skeptical about the very possibility of successful block production with a “stock” unmodified cardano-node version. There may well be something that only a chosen subset of nodes “know” or can do, the rest serving as a distributed network support for free.

That is a pretty baseless accusation. Although the documentation is arguably a bit scattered, there are hundreds of pools of all sizes minting blocks regularly.
