NFT domains
Blockchain domains are the latest addition to the very popular NFT sphere. These fascinating assets, which are part URLs and part collectibles, are becoming the hottest thing in the crypto world.

What are Non-Fungible Tokens? (NFTs)?
Before we get into the nitty-gritty of NFTs, you need to understand the blockchain. Since Satoshi Nakamoto introduced Bitcoin in 2008, the blockchain has baffled the world. This decentralized ledger uses cryptography to permanently link blocks of data together.

The blockchain is the technology that powers Bitcoin, Ethereum and all other cryptocurrencies in the world. It uses this decentralised public ledger to solve a theoretical puzzle of digital currencies.

Cryptocurrencies are what are called fungible tokens. Just as with two separate dollar bills, there is no difference between one Bitcoin and another. They are completely identical in every way. However, cryptocurrencies are not the only thing that blockchains can do.

Non-fungible tokens are the opposite, that is, they are unique tokens and are very suitable for verifying ownership of something. It has become very popular to buy digital art as NFTs, in the future it could go so far that ownership of real estate, loans or other contracts are in the blockchain.

How do NFT domains work?
A blockchain domain system allows domain owners to control their domains using private keys. Unlike traditional domain names, there is no regulatory body monitoring these domains.

Put simply, this means that you don't rent NFT domains, they are purchased and after you own the domain you will never have to pay a renewal fee. It is also not possible to shut down the domain ever, as it lives in the blockchain.

In the past you needed special software to access domains registered as NFTs, but this is becoming easier and today most major browsers support these types of domains.

There are many uses for NFT domains, it is perfectly possible to use the domain in the traditional way, but there are more uses for these domains in crypto.

What are NFT domains used for?
They can replace the long addresses used to send and receive crypto
This means that instead of a long complicated address, you can have a shorter version that is easy to remember. This reduces the risk of accidentally sending to the wrong address.

A typical BTC address is 3FZbgi29cpjq2GjdwV8eyHuJJnkLtktZc5 If you bought the NFT domain smile.wallet, that could have been your address instead.

They can be used to link to web pages
Just like a regular domain name, an NFT can lead to a decentralized web page

They can be used as collector objects

At the moment crypto is growing more and more, these domains have already become attractive collectibles for people who believe that the value will increase significantly in the coming years.
