Securing your wallet - Bitcoin

Bitcoin - The Currency of the Internet

A community dedicated to Bitcoin, the currency of the Internet. Bitcoin is a distributed, worldwide, decentralized digital money. Bitcoins are issued and managed without any central authority whatsoever: there is no government, company, or bank in charge of Bitcoin. You might be interested in Bitcoin if you like cryptography, distributed peer-to-peer systems, or economics. A large percentage of Bitcoin enthusiasts are libertarians, though people of all political philosophies are welcome.

Offline Bitcoin wallet

I would like to have bitcoin and store them as safely as possible. I want bitcoin data to be stored on my disk -- I don't want to some online service to manage my wallet. I also would like to have ability to easily backup wallet data so if my disk fails I can then recreate my wallet from backup.
Nice thing is to have ability to transfer wallet from one program to another so if some program ceased to be developed I can import my private/public keys to another program.
Can you recommend any application like that?

Electrum on Puppy Linux - Bootable USB with Offline Bitcoin Wallet

Here is the video how to do it and the copied short description: https://youtu.be/RBlpWhLVbZo
It took me 3 days to find solution that works. If you like it, send any amount of bitcoin to:
1GHaTVyJo8wG4VqdTevyZa7xSyicMGLikj
Steps:
  1. Puppy Linux ISO has only 220 MB. Download ubuntu-compatible ISO from http://puppylinux.com
  2. Rufus - download portable version from https://rufus.akeo.ie
  3. Create bootable USB using Rufus, selecting ISO of Puppy Linux
  4. Boot from USB to Puppy Linux
  5. Create Save File - if not, all system changes and user file changes will be forgotten on reboot
  6. Puppy Package Manager - Update database
  7. Install packages:
    python-qt4
    python-pip
    python-sip
  8. Install electrum using pip2 command
  9. Protect yourself: turn on firewall
  10. Make USB offline: disable all network adapters
  11. Start Electrum and create your first offline wallet
I hope this will help you not to spend days discovering what works, as it took me. Happy bitcoining!

Lets Get TREZOR the offline Bitcoin Wallet to work with DOGE

Hey guys, I am not sure if anyone else is getting a TREZOR (whenever they ship), but I emailed them the other day wondering if TREZOR will work with dogecoin. They replied that they will see if there is interest from others.
I converted all my bitcoins to dogecoins so I no longer have any use for it. However, I think compatibility TREZOR will do wonders for the safety of those with a lot of dogecoins.
What do you guys think? http://www.bitcointrezor.com/

newb questions - spending offline bitcoin wallets. storing public and private keys.

hi... some newb questions please.
  1. If I have an offline wallet with 2 BTC and want to buy something for 1 BTC - can i spend 1 BTC out of the offline wallet (and have 1 remaining in the offline wallet) or do I have to import 2 BTC into an online wallet and spend 1 from there. I read something saying you have to import the whole amount to an online wallet or else you lose watever is left.
  2. could i just write down the private and public keys on a piece of paper for offline storage - i mean, there is no need for the QR codes i assume/.
i have 0.00001 BTC at moment - can anyone help me out? 1vUAbqSKoKuvtyNW3LHnA3iCct3qLWUe5

Anonymity

Hi,
I am interested in bitcoin and about taxes and stuff. So I know that in my country you must also pay tax over bitcoin, but how can the government know that I say the correct amount of bitcoin I own? I thought it was anonymous. Also, is there a difference in anonymity between offline bitcoin wallets and online like coinbase? How can they track the bitcoin?

Difference Between Bitcoin Vault and a Wallet

Difference Between Bitcoin Vault and a Wallet
Difference Between Bitcoin Vault and a Wallet

INTRODUCTION
Bitcoin at present is the most valued cryptocurrency that is trending around the world. The reason behind it is the trust and security factor which forms an integral part of the technology it uses. The use of Cryptography in securing the transactions carried out while transferring or receiving these bitcoins make it stand out while comparing it with the standard fiat currencies. The research outlined by the University of Cambridge states that more than 5 million users are using bitcoin as of now.
Bitcoin’s can be stored securely using the following methods.
BITCOIN WALLETThe bitcoin wallet is an address that is encrypted using cryptography to store the bitcoins and secured using the public & private key. The person who has access to these keys can carry out financial transactions related to that wallet. These are similar to an account number and the password of an account, a combination of both is needed to access. Based on this logic there are different kinds of wallets as mentioned below.
  1. Paper bitcoin wallet
  2. Online bitcoin wallet
  3. Offline bitcoin wallet
Paper bitcoin wallet consists of information that is encrypted using public & private key and written on a piece of paper. The information is neither entered anywhere in the network nor published, hence remain secured from the hackers. Maintaining this piece of paper could be messy when generating a new key for each transaction. Chance of the paper piece with the keys getting worn out, damaged or lost can permanently lock the funds.
OFFLINE BITCOIN WALLET
The limitation of paper bitcoin wallet is taken care of by using the offline bitcoin wallet that consists of a PC which is used to update the encrypted keys. Offline bitcoins are of two types, hardware and software offline wallet.
The hardware wallet is a personal device that can store this encrypted keys and needs an additional authentication making it more difficult for the thieves. Being a bit expensive and dependency of having to connect to a PC are the just the disadvantages.
While the Software Wallet needs special software that has to be installed on a PC or a mobile device to carry out the same functionality. Direct exposure to malware or virus attacks through the OS of the equipment it uses and internet connectivity are some of the disadvantages.
ONLINE BITCOIN WALLET
Taking a Step forward Online Wallet stores the bitcoin on the cloud and can be accessed via any online device through a Wallet service provider. The advantages of being able to access your wallet anytime and anywhere from the world and the option to recover your wallet through individual authentication makes it very useful and equally loved across the community. The disadvantages are of security concern as the storage is somewhere on a remote location and the wallet service provider is the mediator for your access to the wallet.
BITCOIN VAULT
Vault is primarily a chamber or a room that can securely store anything. In case of a bitcoin vault, the security of the bitcoin is the prime motto. To achieve these different safety measures are incorporated. Meanwhile, the same purpose can also be fulfilled using a wallet, then what is the difference between a wallet and a vault.
The main differences are,
ADVANCED ENCRYPTION
The Capital amount of the transaction is kept withheld for 48 hours for the final confirmation. The confirmation has to come from the owner of the asset or in case of a group vault all the members are required to confirm the transaction to initiate the process. The Vault provider ensures proper authenticated by the owners before processing the transaction.
GEOGRAPHIC DISTRIBUTION
The storing of bitcoin data in a geographically distributed location of network servers for added security is known as Cold storage. Storing the complete data in only one server acknowledged as Hot storage is less secure. All these network servers are not connected to the worldwide network in any form to enhance the level of security.
There are some companies that also provides additional features for their vault users.
CONCLUSION
When you compare the probability of using a Bitcoin Wallet or Vault, the only difference seems to be of security levels. While one emphasizes more on personal trust and safety, the other makes it more secure but with a restriction and dependency. Taking all these into consideration the final decision lies with the user.

VisualBTC - Android-based offline wallet using animated QR codes

Hello everyone,
I've just released VisualBTC, an Android-based offline Bitcoin wallet that uses animated QR codes to send/receive transactions and synchronize with the Bitcoin network.
A quick YouTube video demo is available here .
The idea is very simple: use a cheap 4.3 inch Android tablet with a capacitive screen ($50 in singles, bought from Amazon UK ), disable its WiFi connection and transfer data only over animated QR codes (that is split any long strings into smaller chunks and animate those chunks as separate QR codes).
The application communicates with an HTML5 + JavaScript page that requires no server side components (QR code scanning and generation is all done in JavaScript, webcam interaction is also done locally via getUserMedia(), blockchain data is read and transactions are posted via blockchain.info directly from the page via JavaScript. It works with Chrome, Firefox and Opera. It does not work with Internet Explorer, sorry, at least not yet.
The private keys never leave the tablet and it has no Internet connectivity whatsoever, so it cannot be attacked from the Internet.
The wallet application itself has been designed to be extremely simple, something even your grandma would be able to use. It only has two buttons: Pay and Sync.
Clicking Pay allows you to scan a QR code (standard format, bitcoin:address?...), then assembles a transaction, signs it, then shows an animated QR code with the transaction data. Showing that animated QR code to the webcam at http://www.visualbtc.com/ posts the transaction to the Bitcoin network.
Clicking Sync shows a QR code that you once again scan at http://www.visualbtc.com/ . It then shows you an animated QR code of your unspent outputs. You scan that with your wallet and it updates the balance and the internal list of unspent outputs.
Private key export/import is available using a special "Advanced mode" (hint: click 10 times in quick sequence on the QR code on the main page ).
This first release is free but is currently limited to 1 BTC maximum wallet value and 0.1 BTC per transaction. You can remove this limitation by paying (from the VisualBTC wallet itself) 0.25 BTC to us. You can also send donations and tips to 1VBTCXXcYmUCzYUcmdcakSGdyavUnByFF .
