Has anything been implemented to counter selfish mining/pool centralization? I see many open research issues. https://arxiv.org/abs/2512.01437v2 discusses some countermeasures to the Qubic attack attempted with at least temporary success.

We sponsored kayabanerve to do : https://ccs.getmonero.org/proposals/kayabaNerve-finality-layer-book.html , "The monero team" DataHoarder and sech1 went head to head with qubic and where in the trenches... fixing issues uostream.reg block/tx propagation and improving p2pool in that regaurd.. the bandaid to prevent reorgs greater than 10 blocks
20:21:24
plowsof:
is still in progress .. DNS checkpoints is also an option cc Rucknium ofrnxmr DataHoarder
20:22:12
DataHoarder:
DNS checkpoints as a temporary/emergency measure is still blocked by issues within monero code, in the reorg handling

Is there an additional mitigation for DOS? If blocks are propagated before verification, nodes distant from the source won't be able to attribute validation errors in order to block misbehaving nodes accurately (i.e. the opposite will happen - a misbehaving node can cause honest nodes to be distrusted). Also, invalid blocks would become *much* more expensive for the honest subset of nodes to filter out.

Or is PoW validated before rebroadcast, and that acts ad DoS mitigation? Since an attacker can't spam valid-PoW blocks without the power to >51%.

PoW is validated, and Monero nodes do full validation anyway before accepting the block
20:53:11
UkoeHB:
sech1: ok thanks
20:54:51

P2Pool propagates Monero blocks through submit_block RPC, so there is no node to block if the submitted block is invalid. But PoW check in P2Pool prevents the spam.

It's been exactly 6 months since that P2Pool release, and 90/84/98% of p2pool (main/mini/nano) miners support it. Good datapoint of how miners update to new versions.

UkoeHB:
Any indication of solo/non-p2pool pool usage?

I think supportxmr pool runs p2pool nodes
