I can remember there was a talk over here or on reddit talking about a practical implementation of MultiSig when it comes to signing keys located all around the world.

Instead of passing the partially signed TX around and let others sign it some guy proposed to have a P2P network for that.

Unfortunately I cannot remember the source?
Anyone? Any updates?

This tool lets your generate PDF paperwallet for arbitrary altcoins
using QR-Codes for fast access to the address and the private key.




Howto Create PaperWallet

• Store address and privkey in csv file
     You may select one of three options to generate you wallet.csv file with
     private keys in it. Read the header of the files to adjust the settings to
     your needs.

            to create new empty wallets using vanitygen
            press ***Ctrl+C*** when You have enough
  • 1_createNewWalletsAndMoveCoins**:

• Uncomment _ONE_ note layout input line in 'paperWallet.tex' (line 41-48)
• Generate the PDF
