Mempools only prove nothing if nodes are also conspiring
Are you still blind?
Here is what I taught monsterer before.
Here was some other discussion that linked back to that:
As
I explained to monsterer upthread, it is not possible to objectively prove (with cryptography and math) which chain is the honest one and which one is the dishonest one when there are censored transactions.
[...]
Note however that this minority chain is unprovable to a full node that wasn't online as it was occurring (which was
my point to monsterer)...
You are still getting the logic backwards. No one is trying to prove a minority chain did anything. They can't because they don't exist (with significant frequency).
As a
necessary condition for someone to be 51% attacking to censor transactions is that those minority chains exist at all. If those minority chains
don't exist at all, then no one is attacking.
If someone creates fake minority chains (at significant cost), then it could be inconclusive evidence of an attack. We would have to look closer to try to determine if an attack is taking place, which could include keeping a node online, even if you didn't do so normally.
Possibly, you could be fooled (and be unable to determine otherwise) into thinking an attack took place when one really did not.
But you can't be fooled into thinking an attack did not take place when one actually did take place, unless someone hides all evidence of the minority chain. That is implausible.
I therefore conclude at present, there is no attack taking place.
