I'm fairly new to BitCoin, so please help me understand! Why do we need paper backups? The block chain must be some of the most widely replicated data on the planet. (What would beat it? Probably the Olsen timezone data. Probably not the Linux source.) I have a copy right here.  Smiley

I can't easily imagine any scenario that took out every online instance of the block chain (without also taking out every human that might care about it!)

What am I missing?

Toby.

My thoughts? Paper is far too fragile. Please encode it in a set of these: http://delkin.com/c-155602-archive-archival-gold-cd-r.html

Then let us know where you're keeping it in case we need it.

If that business isn't here in 300 years can we sue?

and what about laminating the paper and locking it in a (large) safe? wouldn't that last longer then digital data that is susceptible to EMI?

You better get a good durable laminator. My back-of-the-envelope calculation for a 1.5 GB blockchain and 2kb per typewritten page means you're going to need to laminate 750,000 pages.

Maybe we could compress the data with QR codes and we'll make the qr codes take up a smaller space then it would then typed out letters.
Apparently you can store 300 alpha numeric characters in a QRcode

what about sending it out to space as radio-waves and once we can travel faster than light, go ahead of it and record.

If we can print at 600 dpi and use 4 dots per bit, we can get it down to 1760 pages. Don't give up, protectors of the chain!

Edit: Omfg! If we can just print 256 colors faithfully this could fit in 8 pages. Lamination of the blockchain is imminent.

or even better: encode it into a virus and spread!

CDRs should not be affected by EM attacks.  Heat would though.   I am buying some of the above mentioned CD-R discs.   People seem to forget that with the mass production of writable digital mediums, the shelf life has really come down.   Thank you for the link.

Optical disk usage is already dying now. They will probably end like floppy disk: no one has a floppy reader today

So good luck reading those disk in like 10-20 years, let alone 300 years

This team at Stanford have encoded a single bit into DNA that is inherited by the bacteria's descendants:

http://phys.org/news/2012-05-totally-rad-scientists-rewritable-digital.html

Ok, one bit does not a blockchain make but they hope to be able to store a whole byte in another decade.

There we go!! Lets just hope that back up encoded virus doesn't get a virus......
