  • The basic idea...

    "The basic idea behind open source is very simple. When programmers on the Internet can read, redistribute, and modify the source for a piece of software, it evolves. People improve it, people adapt it, people fix bugs. And this can happen at a speed that, if one is used to the slow pace of conventional software development, seems astonishing...
    ...The Open Source pages exist to make this case to the commercial world."    - Introduction to Open Source -

    Details: Bitcoin Deck Wallet

    market download Bitcoin Deck Wallet
    DeckWallet is a simple application that allows you to generate up to 52 bitcoin addresses by entering the order of a deck of cards plus an optional password.

    About security
    - Completely offline, it does not requires any permissions.
    - You don't need to type anything (except the optional password), so it's not vulnerable to keyboard malware.
    - Protection against typos and miss-entered cards.
    - 2FA: Option to enter a password (or more than one to create secondary wallets) besides the deck itself.
    - Obscurity: An attacker won't know there are bitcoins in that deck, even if they find it.

    - Shuffle a deck of cards 7 times.
    - Select the number of cards to use. 52 is recommended.
    - Enter every card on the app.
    - Optionally enter a password you won't forget (it's not possible to recover it!).
    - Touch "Go!" to generate up to 52 bitcoin addresses.
    - Optionally, copy the order of the cards into another deck, as backup.
    - Double-check your deck wallet: Touch the 'Check' icon and re-enter the same password and card order.
    - After checking it, send some bitcoins to your deck wallet and store your deck of cards in a safe place.
