Bitcoin Forum

I means not an ordinary one. Just like something happened in Egypt before. The whole country disconnect form other world.

I know bitcoin will still in the network. But can the people in Egypt still use it if someone inside is still mining bitcoin??

I don't understand what are you talkin about
please use words that are easy to understand  ???

I think a fork happens and when connected again the smaller chain gets annihilated, that is actually a very interesting scenario, will wait for more educated inputs.

I means if a whole country or region disconnect from internet.

Bitcoin can run off radio waves

I think it would make bitcoin crash
but If bitcoin really could using radio waves It will safe. Nothing to worry about.

If its only a relatively small area bitcoin won't be impacted too much, but if everything goes offline bitcoin is screwed.

What happened in Egypt was both shocking and re-assuring. Shocking to see how a tyrannical government could cripple a whole countries communications structure so quickly.
Reassuring to see that even with their efforts they were only able to take down 88% of the network and only for a brief time. Shortly after riots, protests and engineers started reconnecting the internet and communicating with satellites. Shutting off the internet was incredibly stupid and one of the quickest ways to get ousted as a leader. This type of attack in the future will likely happen only with deranged tyrants or their opponents who wish to oust them from power by falsely associating the disconnection to the ones in power.

What happened with Bitcoin in Egypt was the following- Most people temporarily didn't have internet at all and therefore couldn't broadcast transactions temporarily, Some with outside satellite and radio connections could process transactions normally, and possibly none to a rare instance of individuals that were connected to a local LAN with enough miners to find a block within that narrow window would temporarily fork the blockchain. (When the internet came back up the fork would be eliminated and those transactions would need to be re-broadcasted.)

Mycelium has the right idea to make Bitcoin more resilient here -

Hardware wallets that work both on the internet and through independent radio gateways.

Thanks. I didn't know that!
