How big of a problem would it be if ISPs blocked all port 8333 traffic? (Reddit Bitcoin)
I guess everyone could switch to another port but what if they blocked that one too, etc? Would it be possible to run the network on, say, port 80 (which they couldn’t block without also blocking the rest of the internet)?
In such a case, a VPN could be used to get around it but what if the ports were blocked globally in some dystopia future?
