You can walk the network graph and talk to any node in the p2p network graph with ports open and check to see if they have a tx in their mempool.

Something is telling me you’re playing pedantic word games to avoid the point, which is it’s absolutely possible to show someone a tx which has been filtered, because it would be a transaction not in any block, nor none of the reachable networks mempool.

Here - let me even help you out - you can create a 0 fee tx, and that would be a “filtered” transaction. It takes a few minutes to do it on a core node in the console.

I mean; I did say call me crazy from the start and I’m not ignoring the point: the point still stands.

Miners would not include a 0 fee transaction unless there are other incentives. Just like some nodes would opt not to relay a transaction with arbitrary data less there is policy alignment.

Therefore I cannot “link” a transaction that has been filtered because it cannot be verified on chain (which would disprove its filtered nature) and I cannot “link” a transaction that has been opted not to be relayed around the network because it would be unable to query it.

A filtered or non-relayed transaction cannot be linked, verified, or queried because it exists outside the bounds of both blockchain inclusion and mempool propagation.

But maybe I’m just crazy. I’m still learning.

The linking of a TX is a TX Hex, you can load it into your node, sparrow wallet, and other bitcoin software.

Correct miners would not include a 0 fee TX short of exogenous incentives. Your opinion on how the network topology works for nodes is a non sequitor.

Here, this is a txhex I just spun up on my node:

Use either sparrow wallet to load it yourself, OR your own bitcoin node using decoderawtransaction.

Whoops, forgot to sign it. Here is the full txhex, also used the wrong vout for the utxo:

Here is another one (can't spend with both, it'd be a double spend):
