Bitcoin Address


SHARE
Private Key


SECRET

A Bitcoin wallet is as simple as a single pairing of a Bitcoin address with its
corresponding Bitcoin private key. Such a wallet has been generated for you in
your web browser and is displayed above.

To safeguard this wallet you must print or otherwise record the Bitcoin address
and private key. It is important to make a backup copy of the private key and
store it in a safe location. This site does not have knowledge of your private
key. If you are familiar with PGP you can download this all-in-one HTML page and
check that you have an authentic version from the author of this site by
matching the SHA256 hash of this HTML with the SHA256 hash available in the
signed version history document linked on the footer of this site. If you
leave/refresh the site or press the "Generate New Address" button then a new
private key will be generated and the previously displayed private key will not
be retrievable. Your Bitcoin private key should be kept a secret. Whomever you
share the private key with has access to spend all the bitcoins associated with
that address. If you print your wallet then store it in a zip lock bag to keep
it safe from water. Treat a paper wallet like cash.

Add funds to this wallet by instructing others to send bitcoins to your Bitcoin
address.

Check your balance by going to blockchain.info or blockexplorer.com and entering
your Bitcoin address.

Spend your bitcoins by going to blockchain.info and sweep the full balance of
your private key into your account at their website. You can also spend your
funds by downloading one of the popular bitcoin p2p clients and importing your
private key to the p2p client wallet. Keep in mind when you import your single
key to a bitcoin p2p client and spend funds your key will be bundled with other
private keys in the p2p client wallet. When you perform a transaction your
change will be sent to another bitcoin address within the p2p client wallet. You
must then backup the p2p client wallet and keep it safe as your remaining
bitcoins will be stored there. Satoshi advised that one should never delete a
wallet.

Why should I use a Bulk Wallet to accept bitcoins on my website?

The traditional approach to accepting bitcoins on your website requires that you
install the official bitcoin client daemon ("bitcoind"). Many website hosting
packages don't support installing the bitcoin daemon. Also, running the bitcoin
daemon on your web server means your private keys are hosted on the server and
could get stolen if your web server is hacked. When using a Bulk Wallet you can
upload only the bitcoin addresses and not the private keys to your web server.
Then you don't have to worry about your bitcoin wallet being stolen if your web
server is hacked.
How do I use a Bulk Wallet to accept bitcoins on my website?

 1. Use the Bulk Wallet tab to pre-generate a large number of bitcoin addresses
    (10,000+). Copy and paste the generated comma separated values (CSV) list to
    a secure text file on your computer. Backup the file you just created to a
    secure location.
 2. Import the bitcoin addresses into a database table on your web server.
    (Don't put the wallet/private keys on your web server, otherwise you risk
    hackers stealing your coins. Just the bitcoin addresses as they will be
    shown to customers.)
 3. Provide an option on your website's shopping cart for your customer to pay
    in Bitcoin. When the customer chooses to pay in Bitcoin you will then
    display one of the addresses from your database to the customer as his
    "payment address" and save it with his shopping cart order.
 4. You now need to be notified when the payment arrives. Google "bitcoin
    payment notification" and subscribe to at least one bitcoin payment
    notification service. There are various services that will notify you via
    Web Services, API, SMS, Email, etc. Once you receive this notification,
    which could be programmatically automated, you can process the customer's
    order. To manually check if a payment has arrived you can use Block
    Explorer. Replace THEADDRESSGOESHERE with the bitcoin address you are
    checking. It could take between 10 minutes to one hour for the transaction
    to be confirmed.
    http://www.blockexplorer.com/address/THEADDRESSGOESHERE
    
    Unconfirmed transactions can be viewed at: http://blockchain.info/
    You should see the transaction there within 30 seconds.
 5. Bitcoins will safely pile up on the block chain. Use the original wallet
    file you generated in step 1 to spend them.

Private Key (Wallet Import Format):
Step 1 - Generate your "Step1 Key Pair"

Step 1 Public Key:


Copy and paste the above into the Your-Part-Public-Key field in the Vanity Pool
Website.
Step 1 Private Key:

Copy and paste the above Private Key field into a text file. Ideally save to an
encrypted drive. You will need this to retrieve the Bitcoin Private Key once the
Pool has found your prefix.
Step 2 - Calculate your Vanity Wallet

Enter Your Part Private Key (generated in Step 1 above and previously saved):
[NOTE: this input box can accept a public key or private key]

Enter Pool Part Private Key (from Vanity Pool):

Your Bitcoin Private Key is a unique secret number that only you know. It can be
encoded in a number of different formats. Below we show the Bitcoin Address and
Public Key that corresponds to your Private Key as well as your Private Key in
the most popular encoding formats (WIF, WIFC, HEX, B64).

Bitcoin v0.6+ stores public keys in compressed format. The client now also
supports import and export of private keys with importprivkey/dumpprivkey. The
format of the exported private key is determined by whether the address was
generated in an old or new wallet.

How do I make a wallet using dice? What is B6?

An important part of creating a Bitcoin wallet is ensuring the random numbers
used to create the wallet are truly random. Physical randomness is better than
computer generated pseudo-randomness. The easiest way to generate physical
randomness is with dice. To create a Bitcoin private key you only need one six
sided die which you roll 99 times. Stopping each time to record the value of the
die. When recording the values follow these rules: 1=1, 2=2, 3=3, 4=4, 5=5, 6=0.
By doing this you are recording the big random number, your private key, in B6
or base 6 format. You can then enter the 99 character base 6 private key into
the text field above and click View Details. You will then see the Bitcoin
address associated with your private key. You should also make note of your
private key in WIF format since it is more widely used.
✔ Good! Your browser can generate cryptographically random keys using
