The network can still continue over microwave. I believe people are doing this now. We also have satellites. This is also being worked on. When pushed into a corner Bitcoin will find a way. We can also pass Bitcoin person to person on open dimes etc

All that said if the net goes down globally we are all fucked and have way bigger problems than Bitcoin syncing for a few blocks.

Bitcoin for the win

If a solar flare etc wipes out the internet then nothing will have any value or work. No ATM's, banks, money is worthless, phones, cars, fridges won't work. Is her point is that it would take the destruction of modern society to stop Bitcoin?

So when was the last time you actually seen governments coordinate globally and actively get together and be able to pull off something like turning off the internet all at once or turning off the electricity all at once? Because I can not name one single time where anything governments have all agreed upon across the globe unilaterally enabled to enact upon cohesively.

Now if you're only talking point against something is a unilateral unforeseen black Swan event of some sort such as electromagnetic pulse nuclear war and/or solar flares destroying all electronics all at once then you are reaching for dystopian nightmare fuel in order to justify your reasonings For why something can't work. Because let's be honest when was the last time any of those things aforementioned have ever occurred globally all at once?

Now to address the actual nightmare fuel that you're talking about if those kinds of things actually occurred your money is going to be the last thing on your mind about how you survive because if those types of things happened the global supply chain would break down and people would be starving therefore the only things that would probably matter would be your guns your bullets and the amount of food and water you have to sustain yourself.

Now to further address the situation if let's say a segment of the world lost connection for any substantial amount of time the network would continue elsewhere in the world and those of us in the blackout area would essentially just continue as normal until we were able to reconnect and catch up with the history of what occurred while we were gone.

If the internet is down the only currency you'll want is ammunition.

A lot of the internet, namely optical cable runs and undersea cables will keep running. Some of them are accidentally or intentionally shrouded in a faraday cage, or are entirely underground/water. Those will survive. The restoration of functionality will likely take weeks but a lot of the network will likely return to full function within months. All the parts of the transport network that don't involve expensive computer control systems that were ungrounded and unshielded will be able to resume.

Yes, we would be in a bad situation. Half the satellites in the sky would drop dead, at least, and fall out of orbit. Tightly controlled logistics systems would come unraveled. There would be civil unrest and much of it would be offline.

This is part of the reason why it is essential some people start thinking about the idea of building caches of essential data that are shielded against a Carrington event.

I think what would happen is the network would basically pause. Then once things were back online it would pick back up where it left off.

Also, you can sync from a satellite or radio even. And if you wanted to transact you could use something like coinkite opendime or just trade private keys in the meantime.

Dual asset trade using barter and where possible cash and putting mesh radio on.

my prediction is that the pressure for connection will be so high that in the next few days some will set up tutorials for using mesh networks and bitcoin will be combatible I guess.
