Bitcoin Name Service (BNS) Explained: A Guide to BTC Domains

Imagine being able to send Bitcoin to a simple, easy-to-remember name instead of a long, complex address. That’s the power of Bitcoin Name Service (BNS) and BTC domains. Here is a detailed explanation.

What Bitcoin Name Service Is

Bitcoin Name Service (BNS) is a decentralized naming system built on the Bitcoin blockchain. It allows users to register human-readable names, called BTC domains, and associate them with Bitcoin addresses. Instead of sending Bitcoin to a long, complex address like “1A1zP1eP5QGefi2DMPTfTL5SLmv7DivfNa,”  you can send it to a simple name like “satoshi.btc.”.

BNS operates similarly to the Domain Name System (DNS) used on the internet, which translates domain names like “google.com” into IP addresses. However, BNS is decentralized, meaning it’s not controlled by any single entity and is resistant to censorship and manipulation.

How does BNS work?

BNS utilizes the Bitcoin blockchain to store and manage BTC domains. When you register a BTC domain, a special transaction is created on the Bitcoin network that associates your chosen name with your Bitcoin address. This transaction is recorded on the blockchain, making the association permanent and secure.

To resolve a BTC domain and find the associated Bitcoin address, BNS clients query the Bitcoin blockchain. They scan the blockchain for the relevant transaction and extract the address associated with the domain. This process is performed entirely on-chain, ensuring the integrity and decentralization of the system.

Benefits of using BTC domains

There are several key benefits to using BTC domains:

1. Simplicity: BTC domains are much easier to remember and share than long, complex Bitcoin addresses. This makes it more convenient to send and receive Bitcoin, especially for less tech-savvy users.

2. Branding: BTC domains can be used to create branded Bitcoin addresses for businesses, organizations, or individuals. This can help to improve recognition and trust among customers and supporters.

3. Security: By using a BTC domain, you can keep your actual Bitcoin address private. This adds an extra layer of security and helps to protect against potential hacks or attacks.

4. Decentralization: BNS is a decentralized system, meaning it’s not controlled by any single entity. This makes it resistant to censorship, manipulation, and single points of failure.

How to register a BTC domain

Registering a BTC domain is a relatively simple process that can be completed in a few steps:

1. Choose a BNS provider: There are several companies that offer BNS registration services, such as Namecoin and Blockstack. Research the available options and choose a provider that suits your needs.

2. Search for your desired domain: Once you’ve chosen a provider, use their search tool to check if your desired BTC domain is available. BNS domains usually end in “.btc,”  but some providers may offer other extensions.

3. Register and pay for your domain: If your desired domain is available, you can proceed with registration. You’ll need to provide your Bitcoin address and pay the registration fee, which varies depending on the provider and the length of the registration period.

4. Confirm your registration: After completing the registration process, your BTC domain will be associated with your Bitcoin address on the blockchain. This process may take some time, depending on the speed of the Bitcoin network.

Managing your BTC domain

Once you’ve registered your BTC domain, you’ll need to manage it to ensure it remains active and associated with your desired Bitcoin address. Here are a few key points to keep in mind:

1. Renewal: BTC domains are registered for a specific period, typically ranging from 1 to 5 years. Make sure to renew your domain before it expires to maintain ownership.

2. Updating your address: If you want to change the Bitcoin address associated with your BTC domain, you’ll need to update your BNS record. This process varies depending on your BNS provider, but usually involves creating a new transaction on the Bitcoin network.

3. Transferring ownership: If you want to transfer ownership of your BTC domain to another party, you’ll need to follow your BNS provider’s transfer process. This usually involves updating the BNS record to associate the domain with the new owner’s Bitcoin address.

Frequently Asked Questions

1: How much does it cost to register a BTC domain?

The cost of registering a BTC domain varies depending on the BNS provider and the length of the registration period. On average, you can expect to pay around $5–$20 per year for a BTC domain.

2. Can I use my BTC domain with any Bitcoin wallet?

Not all Bitcoin wallets support BNS and BTC domains. However, many popular wallets, such as Electrum and Blockchain.info, have integrated BNS support. Before registering a BTC domain, check if your preferred wallet is compatible.

3. Are BTC domains case-sensitive?

Yes, BTC domains are case-sensitive. For example, “Satoshi.btc” and “satoshi.btc” are considered different domains.

4. What happens if I forget to renew my BTC domain?

If you forget to renew your BTC domain before it expires, you risk losing ownership of the domain. Someone else may register the expired domain, and you’ll no longer be able to use it. To avoid this, make sure to renew your domain well before the expiration date.

5. Can I use my BTC domain for other cryptocurrencies?

BTC domains are specifically designed for use with Bitcoin. However, some BNS providers offer similar naming services for other cryptocurrencies, such as Ethereum and Litecoin. These services use different extensions, like “.eth” for Ethereum domains.

6. Are BTC domains stored on the Bitcoin blockchain forever?

Yes, BTC domains are stored on the Bitcoin blockchain as long as the blockchain exists. This means that even if a BNS provider shuts down, your BTC domain will still be associated with your Bitcoin address on the blockchain.

7. Can I sell my BTC domain?

Yes, you can sell your BTC domain by transferring ownership to another party. The process involves updating the BNS record to associate the domain with the new owner’s Bitcoin address. Some BNS providers and third-party marketplaces facilitate the buying and selling of BTC domains.
