You mean like the 1sat/byte everyone here keeps touting? Or are you advocating we pay 10+ sat/byte to uphold the zero-conf narrative?
Enough that it's above the threshold most miners have set for their mempool yeah. 1sat/byte is enough for now but it'll be a moving target as activity ramps up.
Right! The way to make 0-conf safe is raise the block size! Miners automatically find the fastest way to propagate txns because they're keeping an eagle eye out for incoming blocks.
