No the US does not have code that can be sent out as a 'Kill switch'. The global networks are just too independent and self-healing for any attempts at 'killing the internet' to have long-term success. Yes the various countries that hold the major DNS servers and main fiber trunks end-points can easily muck things up for a while if they want to and can certainly take down/control networks within their borders. Thing is, As China found out when they tried having the GFW redirect certain address queries eventually ways are found to circumvent it.
The most prominent example of how the internet functions outside of ANY government control is the DarkNet/Web which is comprised of a gazillion independent servers that are directly accessed via their actual TCPIP addresses. Unless one takes down every single ISP along with every possible way they can communicate (fiber/radio/old-school copper/etc) with each other in every country on Earth the networks will survive. Won't be particularly fast or reliable though.
I understand that there is <5% chance that any of this will happen. I was having this conversation with someone, and I said there is a way to bypass practically any regulation, and this is what they said:
Right, but those still require an internet connection to your ISP. Once ISP's are forced to authenticate all user's QR code on their proprietary routers (which you cant opt out of) were fucked. The only way BTC will work is with decentralized radio mesh networks…..
I understand what you're saying, but once the proliferation of Digital ID's come in, the authentication technology will change. CCP blocks everything at the national firewall level, where as future censorship will be at the local, router level. I work in IT and cybersec
I cannot confirm whether they work in IT, but what are your thoughts on this?
