Aren't mempools specifically designed to make valid transactions censorship resistant?
Discussion
Sorta. One of the main purposes of mempools and the gossip network is to surface the most valuable transactions to all miners. Mempool policy is a stricter than the consensus rules, though.
Makes sense! I guess if it were *specifically* designed for censorship resistance you'd hold onto all older valid transactions, even if they have low fees, and broadcast them to other nodes more than once.
Maybe we can do that when we have the one-shot broadcast via Tor for transactions
