Is it a bad idea to use a bitcoin wallet address in a domain name or URL?


If you mean as part of a URL or domain name, then yes, I think it's a bad idea. If your private key is somehow compromised (eg through a stolen or hacked PC) you may no longer want to use that address, but your users may have it in their bookmarks for years afterwards.

However, as long as it didn't have any particular meaning (such as being accompanied by an instruction to donate to that address), it may not cause any harm. Secondly, it's easy to redirect a user's browser to a new page if you need to.

Usually URLs are best kept short unless it's a sub-section of a site used for sharing or bookmarking. Keeping them looking like words (as much as possible) helps with usability, so unless your vanity address is the longest ever generated and you want to show off, I can't see a good reason to include it...

Address reuse refers to the use of the same address for multiple transactions. It is an unintended practice, abusing the privacy and security of the participants of the transactions as well as future holders of their value. It also only functions by accident, not by design, so cannot be depended on to work reliably.



Address reuse harms the privacy of not only yourself, but also others - including many not related to the transaction. In some cases, these risks are serious enough that they are likely in violation of reasonable consumer protection laws.

When addresses are re-used, they allow others to much more easily and reliably determine that the address being reused is yours. Every time the re-used address's private key signs a fresh transaction, whoever receives it can use the histories of that address to discover information about you, and everyone who is interested in discovering the identity of the address's owner has one more...

Bitcoin is the currency of the Internet: a distributed, worldwide, decentralized digital money. Unlike traditional currencies such as dollars, bitcoins are issued and managed without any central authority whatsoever: there is no government, company, or bank in charge of Bitcoin. As such, it is more resistant to wild inflation and corrupt banks. With Bitcoin, you can be your own bank.

The key to keeping your Bitcoin transactions from being traced back to you is preventing others from knowing which addresses are yours. If you’re trying to remain anonymous (or more precisely, pseudonymous) with Bitcoin, read on for the most common ways people’s true identities are forever associated with their Bitcoin addresses. And try to avoid them.

It might also be worth checking out Using Bitcoin Anonymously for other best practices and pro tips.

India’s leading Bitcoin exchange, Coinsecure, has announced its partnership with Netki with the purpose of allowing its Bitcoin wallet users to create their own wallet names. The aim is to make the wallets easier to use and more reliable.

Many users have difficulty memorizing the address of their wallet. This problem is faced by many exchanges as, for mass adoption of Bitcoin by casual users who don’t have knowledge of cryptography to occur, there must be a simpler way of presenting the long list of numbers that is a wallet address.

CoinTelegraph reached out to Global Business Development Head at Coinsecure, Elizabeth McCauley, asking for her thoughts on the matter.

CT: Will it be possible for users to create a wallet name without using their real name?

Elizabeth McCauley: A person can create whichever ID he would like as long as the name is still available.

CT: Will it be possible to create separate wallets for different functions?

A cool function of Bitcoin not mentioned in introductions is its message signing and verification feature. I'll use the Satoshi client on a Mac as the example but the same functions are available in the wallet at and in any decent Bitcoin client.

Suppose you have a dispute with a vendor you paid in bitcoin. They say you didn't pay them the correct amount or they didn't get paid at all. So you show them the record of the transaction.

Great, says the vendor, but how do I know that's your coin?

In the Satoshi client, go to the "Receive Coins" tab. At the bottom, you'll see an option that says, "Sign Message" (you can also go to File > Sign Message). Enter the Bitcoin address that you own that initiated the transaction (that's the address to the left of the green arrow in the transaction record mentioned earlier) into the address form. Write your message and then hit the "Sign Message" button.

The signature generated is unique to the address...

Using your smartphone or tablet as a wallet isn’t all that new. I had wonderful wallet programs that held virtual versions of my cards, numbers, barcodes, and even pictures way back when I had my Newton and on my first Pocket PCs. The convenience of yesterday’s digital wallet wasn’t anywhere near that which it is today. Back then a digital wallet was nothing more that a convenient place for you to store your numbers so they were right there with you.

Now, however, your “digital wallet” is just that. Your phone can hold your credit cards, reward cards, even your plane ticket. I use Google Wallet almost every day. All of these are just hooks into where your actual currency or credit lives. What about storing actual currency on your smartphone? You can do that, too, but using your mobile device as your Bitcoin wallet is a bad idea!

Most currency isn’t “money”. Money is based on tangible things that hold intrinsic value like Gold, Silver, pork...

Hello Everyone!

I'm a total newbie with Bitcoin so forgive me if I'm asking stupid things. All help needed!

My plan is to implement a way to pay with Bitcoins in my webshop.
My problem is to generate bitcoin-adresses with PHP. How should I do that?

I already managed to use addrgen.php (from but that needs a MPK in 64base. When I use Electrum on Bitcoin Core I do not have an 64base MPK, I have something else

Any ideas how to:
a) convert Electrum or Bitcoin Core private keys to 64base so that I can use this addrgen.php?
b) some other PHP sample that I can modify to produce limitless Bitcoin-adresses?
c) some other idea?

All hints and ideas are welcome!
BIG thanks in...

What is Bitcoin address ?

A Bitcoin address, or simply address, is an identifier of 27-34 alphanumeric characters, beginning with the number 1 or 3, that represents a possible destination for a Bitcoin payment.

In simple terms, if you want to receive bitcoins from some one you must provide them your bitcoin address where they will send you bitcoins. Like e-mail ( where you send email message to person's email address) , you can send bitcoins to a person by sending bitcoins to one of their addresses. A person can have many different Bitcoin addresses.

Bitcoin address looks like below :


How do I get one ?

Addresses can be generated at no cost by any user of Bitcoin. One can install official Bitcoin-Qt software, click "New Address" and be assigned an address. You can download bitcoin software from below location :

Many people often wonder: What’s the difference between a wallet and an address? Are they the same and if not, how do they differ?

The short answer is that they are two different things, with the address being the ID of where the Bitcoins are being held, while the wallet is program controlling the address and facilitating transfers to and from the address.

Explaining it more in depth:

An address is a Bitcoin public key to which transactions can be sent. It represents the public key of an asymmetric key pair. The private key of this “key pair” is used to sign transactions or otherwise prove ownership of an account. A signature can only be created if the correct private key is used. The signature can then be verified by anyone by using the associated address (i.e. “the public key”).

A wallet, on the other hand, is a collection of private keys that correspond to addresses. It is the data needed in order to receive and spend bitcoins The Bitcoin client...

A couple of months ago we had the opportunity to develop an innovative financial application powered by Bitcoin – a virtual cryptocurrency that isn’t going anywhere any time soon! You might actually want to start using it already.

Mobile apps can develop a payment app by integrating Bitcoin as a payment option at check-out along with all other methods for online payments. What we will be discussing first, however, is how to develop a mobile Bitcoin wallet. Let’s take a brief look.

The project that I’m developing is basically a money transfer system that uses a Bitcoin mobile wallet. I’ll start off by explaining the advantages of mobile payment transfer apps, as well as by explaining their implementation.

1. The simplest form of exchange

The digital nature of Bitcoin makes the virtual currency a perfect solution for cross-border transactions. It is fast and low-cost. Other payment options are slower and more expensive. With this cryptocurrency...
