3D NFTs, or Non-Fungible Tokens, are the latest trend in digital asset ownership. They are a form of digital asset that is unique, completely non-fungible, and immutable, allowing anyone to securely own and trade digital assets in a brand new way.

3D NFTs are created using 3D modeling tools such as Blender and 3D Studio Max, and stored on the blockchain, making them secure, transparent, and immutable. It’s now possible to own and trade digital assets in a new way. This article will take a closer look at what 3D NFTs are, how they work, and how you can use them to your advantage.

How Do 3D NFTs Work?

In order to own a 3D NFT, you will need a digital wallet that supports the creation and trade of 3D NFTs. These wallets will store your 3D NFTs, making them easy to trade with others and view your ownership rights in the blockchain. If you want to trade your 3D NFTs, you can easily do so by sending your 3D NFTs from your wallet to the wallet of the individual you want to trade with.

How are 3D NFTs Different from Other Digital Assets?

3D NFTs are different than other digital assets in that they are completely non-fungible. This means that each 3D NFT is completely one of a kind, making each one completely different from the next. Because each 3D NFT is one of a kind, each one will have its own value that can fluctuate depending on the demand for that 3D NFT.

Benefits of 3D NFTs

There are many benefits to using 3D NFTs over other digital assets. First and foremost, each 3D NFT is completely one of a kind, making them completely unique and interesting. This makes them much more exciting to collect, trade, and own. Since each 3D NFT is completely one of a kind and can be anything, they are much more interesting to own than other digital assets.

3D NFTs are also secure, transparent, and immutable, meaning that they can’t be hacked, all ownership rights can be seen by anyone, and they can’t be changed or manipulated in any way. Finally, they are also easy to create and trade, meaning anyone can start collecting and trading these digital assets.

How to Create 3D NFTs?

To create a 3D NFT, you need to follow these steps:

  1. Create or obtain a 3D model: You can create a 3D model from scratch using software like Blender or obtain one from an online marketplace.
  2. Convert the 3D model into a GLTF file format: This format is supported by most NFT marketplaces and makes it easier to display and view the 3D model in various environments.
  3. Mint the NFT: Minting is the process of creating a unique, one-of-a-kind token on the blockchain. You will need to use a blockchain platform like Ethereum and a tool like OpenSea to mint your 3D NFT.
  4. List the NFT for sale: Once you have minted your NFT, you can list it on various marketplaces such as SuperRare, Rarible, or OpenSea.

Where to Buy and Sell 3D NFTs?

There are various places where you can purchase and sell 3D NFTs, making them easy to trade with others. You can purchase 3D NFTs from online 3D asset marketplaces, such as Rarible, which allow you to purchase and sell unique 3D NFTs.

You can also use other known marketplaces, such as OpenSea or Magic Eden, to easily purchase and sell 3D NFTs.

How to Store 3D NFTs?

You will need to store your 3D NFTs in a digital wallet that supports 3D NFTs. Several different wallets support 3D NFTs; many even have mobile apps that make it easy to trade and collect your 3D NFTs.

How to Use 3D NFTs for Your Business?

If you want to use 3D NFTs in your business, they can be a great way to engage with your customers.

You can create your own 3D NFTs to give to customers, allowing them to trade and show off their digital assets.

You can also sell unique 3D NFTs, allowing customers to own rare, one-of-a-kind assets.

You can also use 3D NFTs as a loyalty reward, giving your customers a unique digital asset to show their loyalty to your brand.

The possibilities are endless. Reddit is a good example of this.

Types of 3D NFTs

There are various types of 3D NFTs you can collect and trade. You can collect unique video game characters, unique pieces of art, limited-edition sneakers, or even use 3D NFTs for marketing campaigns.

No matter what type of 3D NFT you collect, they will all be completely one of a kind, making them much more interesting to collect and trade than traditional digital assets. Also, 3D NFT projects are numerous and range from digital art to virtual real estate. 

Some of the most popular 3D NFT projects include:

  1. Decentraland: A virtual world where users can buy, sell, and build on virtual real estate using NFTs.
  2. Axie Infinity: A game where players can breed, battle, and trade creatures called Axies using NFTs.
  3. Bored Ape Yacht Club: A collectible game where players can own and trade unique, cartoon-style apes as NFTs.

Legal implications of 3D NFTs

There are very few legal implications to collecting and trading 3D NFTs. While you should always research to ensure you follow all applicable laws, most of these laws focus on trading and selling 3D NFTs rather than collecting and owning them.

The Bottom Line

In conclusion, 3D NFTs are a new and exciting development in the world of digital assets, providing a way to prove ownership and authenticity of 3D models and monetize digital art, games, and virtual assets. With the potential for limitless applications, 3D NFTs are poised to revolutionize the way we think about and trade digital assets.

Ethereum Vs. Ethereum Classic: What's the Difference?

Token Metrics Team

Ethereum and Ethereum Classic are two of the most popular cryptocurrencies in the world today. Both of these digital currencies have exploded in value over the past few years and have become some of the most sought-after investments in the crypto market. 

But what is the key difference between ETH and ETC? 

Ethereum (ETH) and Ethereum Classic (ETC) are both blockchain networks, but they have a few key differences that make them unique. Ethereum is a newer platform that is designed to be more scalable and secure than Ethereum Classic. Ethereum Classic, on the other hand, is an open source blockchain network that has a focus on decentralization, immutability, and censorship resistance. In this article, we'll compare the two networks and explain why Ethereum is the better choice for most investors.

Overview of Ethereum and Ethereum Classic

Ethereum (ETH) is a decentralized blockchain network that runs smart contracts and enables the development of decentralized applications (dApps). Ethereum was created by Vitalik Buterin and officially released in 2015. 

Ethereum Classic (ETC) is an extension (not a clone) of the original Ethereum, which was forked away by the Ethereum Foundation by launching a new protocol just an year later in 2016. 

To be precise, Ethereum Classic was created when the original Ethereum network and currency were split following the DAO hack in 2016. Ethereum and Ethereum Classic are both open source networks that are maintained by their respective development teams. Unlike Bitcoin, both Ethereum and Ethereum Classic use a Proof-of-Work consensus algorithm. Both these networks also use a native digital token to fuel their networks. 

As Ether is the native token of the Ethereum network, you can use it to pay for transaction or computational services on the Ethereum network. Similarly, ETC tokens are used by participants on the Ethereum Classic network.

But, the majority of the crypto crowd still needs a clean chit over the key differences that make them absolutely distinct. 

So, let’s get into it.

Differences between Ethereum and Ethereum Classic

Scalability - Ethereum (ETH) and Ethereum Classic (ETC) are both open-source blockchain networks that allow you to build decentralized applications. However, Ethereum has been designed to be more scalable. That means the network can handle more transactions at a higher speed, making it a better choice for everyday applications. 

Security - While both Ethereum and Ethereum Classic are secure blockchain networks, Ethereum is more scalable and has a better security track record. Ethereum Classic has been dealing with network security issues since its inception. 

Decentralization - Decentralization is one of the core values offered by blockchain networks like Ethereum and Ethereum Classic. Decentralization on the Ethereum network is slightly better than Ethereum Classic, but both networks have a long way to go before they can be considered decentralized. 

Immutability - Immutability is another core value offered by blockchain networks. However, the Ethereum and Ethereum Classic networks are still very far from achieving full immutability. Both networks have suffered from various instances of data manipulation. 

Censorship resistance - Censorship resistance is another core value offered by blockchain networks. However, both Ethereum and Ethereum Classic are far from achieving full censorship resistance. Both networks can be subjected to censorship by governments and other centralized entities. 

ETH vs ETC - Which is the Better Choice for Investors?

While both Ethereum and Ethereum Classic are great investments, we believe Ethereum is the better choice for most investors for a few reasons. First, Ethereum is more decentralized. Second, Ethereum has been around longer than Ethereum Classic. This means the network is more scalable, secure, and well-established than its competitor. Finally, Ethereum has a wider range of applications than Ethereum Classic.

Overall, Ethereum is the better blockchain network when compared to Ethereum Classic.

The Bottom Line

Ethereum and Ethereum Classic, both of these networks have exploded in value over the past few years and have become some of the most sought-after investments in the crypto market.

When the DAO got hacked and lost $50 million, Ethereum needed a solid technology to replace the old one. So, a hard fork was done. But many traditional supporters of Ethereum did not want to go with the hard fork, and they stayed with the old blockchain technology. As a result, Ethereum Classic was born.
