What if we had a machine that printed out the entire blockchain?
What good does that do you if most everyone's private keys are wiped as well?

Was just thinking of paper again and remembered that program called "paperback",

Unfortunately it's Windows only but it prints a page size bitmap of data and can fit around 500K per page. So if you were going to print blocks as they were found then that would be the way to do it. Or something similar. I never found a linux version. Maybe there is something out there for this? I would prefer a cmd line tool that could be piped to lpr.
Anyway, that should use max 1 or 2 pages per block. Early blocks would be only 1 page. Even still that's around 212,000 pages. Quite a bit of paper. Maybe print multiple block per page by saving them up until a 500K size is met. Maybe you can fit 10 blocks/page then. In which case this shrinks down to 21,200 pages, or double sided about 20 packs of 500 sheets bond paper.
Not so bad. But then who's going to scan those back in after the EMP?

DVDs only last so many years..
we need the blockchain etched in stone!

I suspect that after an "earth-level" EMP, bitcoins, gold, paper fiat will all become useless as currency. People will quickly revert to trade in the things they need to survive: weapons, ammunition, fresh water, food, building supplies, etc.

^yeah i was going to say, just burn to DVD/Blu-Ray.
you'll just need to find a working DVD/Blu-Ray drive to read it after the EMP has destroyed all the current ones.
If you can't find a DVD drive then where are you going to find a computer? And since there's so much power system automation I suspect there would problems just with electricity.you'll just need to find a working DVD/Blu-Ray drive to read it after the EMP has destroyed all the current ones.
And what kind of EMP would wipe out the entire planet? I could see something hitting from space on one side but would it also affect the dark side?

Isn't there some more feasible way besides paper? Couldn't the block chain be backed up on DVD-RW and then every ten minutes new blocks could be written out. Are DVD-RWs wiped by an EMP? I'm pretty sure not but I've never read up on this. This would be much less wasteful and easier to manage.
paper wallets are a standard idea at this point.
read about an earth-level EMP scenario. What if we had a machine that printed out the entire blockchain? just kept crankin' pages every 10 min or so. seems worthwhile IMO, although I haven't slept much recently and have not calculated the scale of this in my head yet.
