This is a very thorough analysis

> view–key–based verification can be applied only to blocks that are already definitively included in the main chain; it cannot be used for blocks that are still within an ongoing epoch or for blocks that have already become orphaned.
03:54:29
datahoarder:
It can. That's how I released my orphan blocks with proofs, they were done using viewkeys. Monero GUI/CLI indeed does not let you verify them, but a custom verifier is able to check all orphan blocks later on
03:54:29
datahoarder:
Example: https://blocks.p2pool.observer/block/b7899ad5f54b8f4ebfdbe44f64d36517b9b1f7994eaaede1aa40b41b6ef2f143[... more lines follow, see https://mrelay.p2pool.observer/e/y7OUsc8KeE1fWWdZ ]
03:55:28
datahoarder:
The adaptation involves feeding the miner tx directly, not grabbing it from blockchain data (as it is orphaned)
03:56:33
datahoarder:
For example, orphan blocks listed here https://irc.gammaspectra.live/419c0c2b6e8bac8c/qubic-blocks-epoch178.csv include additionally the full block for any verifier to confirm this.

> Empirical refutation of strategic utility: We demonstrate that the deployed strategy was economically ineffective, contrary to the context promoted by the pool.
04:01:01
datahoarder:
this was also seen empirically ^ though they improved towards the later days, it still was subpar (from empirical estimates myself they were running ~18% loss compared to pure mining, later on ~10% loss)
04:12:56
datahoarder:
> its expected revenue ratio should also fall within this interval, implying a relative loss of roughly 9% − 36% compared to honest mining at the same hashrate.
04:13:20
datahoarder:
oh! similar results for them using only main block data and task
04:15:26
datahoarder:
(they later estimate 12% from empirical data and not simulations)
04:18:58
datahoarder:
They really had a lack of granular data, which we gathered with more granularity (example, the "timeline logs" on https://github.com/WeebDataHoarder/Monero-Timeline-Sep14 which aren't even as verbose as they are in real life, we have 800 GiB of dumps and ~100 GiB of microsecond accurate hashrate submissions and task logs)
04:21:34
datahoarder:
The way they processed the data is consistent with internal methods, and they verified the same assumptions (timestamp delay they measured was around 5s, but we had these within 20-80ms of the tasks being created)
04:23:04
datahoarder:
Good report, it does not include times during August sadly and they might have missed orphan blocks that didn't end up on the network (but templates for them exist)
04:35:27
datahoarder:
Here's some of the granular measured hashrate they had, from Aug 11th to Oct 16th.

Hi. FOSDEM. Anyone want to go? And if so, any people specializing in the p2p networking of Monero want to do a talk or workshop?
