Bitcoin must prevail, its code does not permit any other outcome.

It's just not possible. As long as there's a single copy of the blockchain anywhere, on any hard drive in the world, the network will rebuild itself, even if every other node had been destroyed. It may seem unsettling, but there is actually nothing that can stop it, short of 'turning off the internet', which is of course impossible, since the internet itself was designed to reconfigure itself in the face of any disruption.

A single copy of the blockchain is open to manipulation.

Not really, you need hundreds of millions of dollar of hardware and electricity to work months for you to recreate another one.

Yes. Satoshi's paper is right there at bitcoin.org - surprising how few people seem to have actually read it.

Except for the latest few weeks or maybe a month, most miners could recreate most of the early stuff with ease. Especially if you have a farm.

Remember the last blockhash of a recent date and you will really give them some big headaches.

Yes.
You know this how?
What stops the first person coming online from doing a 51%?

That's not how 51% attack works, you need to have a main blockchain you don't work on first to pull off a 51% attack.
Use your brain.
If you came on first wouldn't you start mining (lets say the diff. adjusted)? Then you'd be 100% hashrate.

There has to be two competing blockchains, or there is no way to do double-spending, thus no 51% attack.

You simply have no idea what 51% attack is, read more, talk less.

And precisely what could you accomplish, all alone on your private network with 100% of the hashing power?

Exactly. Nothing.

Why wait for an EMP? - go ahead, unplug your internet connection and give it a go!

Minimum Effort/Maximum effect
as far as I know the banking system uses a 5 back-up system, you find the locations of all the servers emp blast those and you reset the entire credit system for that individual bank... they'd never be able to recover, not without serious back-tracking, only money that could be traced to other banks would be safe. But that would still mean a large chunk of the inflationary money supply would be destroyed.

over a wide area a orbital detonation could wipe out all the servers in North America, all those banks would be destroyed... the blockchain would go on.

You could just burn it to a Blu-Ray disc or a few DVDs. If you want it to last longer then try an M-Disc. All of them are EMP-proof. Any optical media really.

EMP make electronics fail.. EG your power supply will blow. this will not do much to the hard drive or the USB key that is not plugged in..

so you would buy a new PSU and maybe a new mainboard. then plug in your hard drive and away you go again.

for a solar flare to cause this, it would only in reality even at the most deadliest flare imaginable, affect electronics on the side of the planet in daylight at the time (side facing the sun) if it were an EMP from a nuclear explosion that was able to reach around the whole of the planet. then the radioactive puss filled blisters all over your body that will slowly kill you in hours would be more of a concern then the wealth you held back for retirement
Interesting. I was actually thinking about this: what if the internet stopped working for a day, would the network just resume normal operations as soon as people started coming back online?

Yes.

That doesn't really answer the question.
I asked what would happen to the network, not with us.

I guess you've never heard of packet radio. There are octogenarians in your very community that are prepared to restore a low-bandwidth version of the internet over the airwaves. With equipment stored in faraday cages to escape the initial EMP issue.
No I haven't heard of such things.

Well - they exist- which is why none of these  "no more blockchain" scenarios can ever actually happen in real life.

The blockchain is almost certainly the data most likely to survive any apocalyptic event by it's unprecedented ubiquity alone. Especially now that a forum member is apparently busy printing a paper copy for backup...

What if we get hit by a massive solar flare, that could leave us without electricity, computers, internet for a prolonged time.
Would Bitcoin die?

No. Nothing can kill it unless every last copy of the blockchain, everywhere in the world is destroyed. If that ever happens, bitcoin will be the least of anyone's worries.

As long as the internet exists and there is one copy of the blockchain left, the bitcoin network will rebuild itself. It's not going anywhere.


Did you just read what I said. A massive one would take out everything.
It's true bitcoin wouldn't be among the priority list of worries, but I'm asking for it specific.
What would happen to the network if it was down for a month, no miners, no users, no nodes, no nothing?

Microfilms could be utilized to store the blockchain I believe.
