Let's dive in!

What Are NFTs?

NFT stands for "non-fungible token."

Non-fungible means the asset is unique and can't be replaced by an identical item. For example, a Bitcoin is fungible - 1 BTC equals any other 1 BTC. But an NFT is unique - no other NFT will have the exact same properties.

NFTs are digital assets that represent ownership of a unique physical or digital item, such as:

  • Digital art
  • Collectibles like trading cards
  • In-game items
  • Music
  • Videos
  • Virtual avatars and metaverse items
  • Tweets
  • Digital land deeds

Each NFT:

  • Has a unique identifier code
  • Is indivisible - you can't trade partial ownership of an NFT
  • Is not interchangeable with another NFT

NFTs prove authentic ownership of a digital asset by recording the details on a blockchain ledger. An NFT acts like a certificate of authenticity for a digital asset.

How NFTs Work

Most NFTs are issued on the Ethereum and Solana blockchain at the moment, using standards like ERC-721 and ERC-1155 in the case of Ethereum and Metaplex in the case of Solana. These standards allow the creation of unique digital assets.

For example, when an artist mints an NFT for their artwork, a token is generated that links to that specific creative work. This token is then sold to a collector and the details are recorded on the blockchain.

The collector now owns the official version of that artwork - the NFT proves their ownership and authenticity of that digital art piece. All future sales and trades of the artwork will be updated on-chain.

NFTs can also have additional features like:

  • Proof of scarcity: The NFT supply can be limited to add exclusivity and value.
  • Royalties: Original creators can earn royalties automatically on all future sales.
  • Metadata: Extra data like descriptions, attributes, and other information can be stored in the NFT.
  • Interoperability: NFTs from different platforms can interact through the blockchain.
  • Composability: NFTs can be combined together to create new NFTs.

Real World NFT Use Cases

Here are some leading real-world examples demonstrating the versatility of NFT applications:

Digital Art

Digital artists are using NFTs to sell their work. For example, graphic designer Beeple sold an NFT collage for over $69 million at Christie's auction house.

NFTs provide digital artists control over ownership and scarcity for their creative work. They also earn royalties automatically on secondary sales.

Collectibles

NFTs are ideal for creating unique digital collectibles and proving ownership. Dapper Labs' NBA Top Shot has seen over $780 million in sales for its basketball video highlight NFTs.

Other popular collectible NFT projects include CryptoPunks, Bored Ape Yacht Club, Cool Cats, and more.

Gaming Assets

In-game assets like skins, weapons, avatars, and tokens can be tokenized as NFTs. This gives players true ownership of rare gaming items.

Games like Axie Infinity and The Sandbox have incorporated NFTs into their crypto game economies.

Music

Artists like 3LAU and Kings of Leon have released albums as NFTs to engage fans in new ways. Music NFTs can also represent exclusive perks like VIP access and memorabilia.

Additionally, NFTs enable musicians to earn royalties directly from secondary sales.

Domain Names

NFT domain projects like Ethereum Name Service (ENS) are using NFTs to create blockchain-based domain names. Owning the NFT proves ownership of the domain.

For example, the wallet address ENS: mywallet.eth could be tied to the NFT for mywallet.eth.

Virtual Land

Virtual worlds like Decentraland, Cryptovoxels, and The Sandbox are using NFTs to sell virtual land parcels. Owners can build experiences on their virtual land NFTs.

As metaverses grow in adoption, virtual real estate is attracting investors' interest.

Event Tickets

NFTs provide a way to sell event tickets and prove ticket ownership in a decentralized way. NFT tickets can't be duplicated or counterfeited.

Platforms like Yellowheart are selling event tickets as NFTs that are tradeable on secondary markets.

How to Buy and Sell NFTs

If you want to start purchasing NFTs, here are a few options:

NFT Marketplaces

Open marketplaces like OpenSea, Tensor, Rarible, MagicEden, and SuperRare allow anyone to buy, sell, and mint new NFTs. These are popular places to find digital art and collections.

You'll need a Web3 wallet like Ned Wallet connected to browse and purchase. Look for active communities with high-quality work when evaluating projects.

Direct from Artists

Many artists choose to sell their NFT work directly through their own website or platform. This allows them to control the terms and build community.

For example, musician Grimes sold $6 million worth of her NFT art directly to collectors. Buying direct like this requires more research.

Social Token Platforms

New platforms like Roll and Bonfida allow creators to launch their own social tokens and NFTs. These platforms handle the technical backend.

As an investor, this is an opportunity to get early access to emerging creator NFT projects.

Gaming Platforms

If you want in-game NFT assets, browse gaming platforms like Axie Infinity and The Sandbox that incorporate NFTs into their economies.

You can purchase rare NFTs directly from other players or through their own NFT marketplace integrations.

Auction Houses

Major auction houses like Christie's and Sotheby's have started holding NFT art auctions. This adds more legitimacy to the NFT art market.

To bid, you'll likely need to complete an application and have funds ready. Expect strong competition on high-profile pieces.

Decentralized Exchanges

Some NFTs, especially newer projects, will only be available on DEXs like Uniswap or SushiSwap through liquidity pools.

You need to already own crypto like ETH to exchange for these NFT assets. The assets may not yet be listed on aggregators like CoinGecko.

How to Create Your Own NFTs

Want to mint your own NFTs? Here are a few options:

Use an NFT Marketplace

Many NFT marketplaces like OpenSea allow creators to easily mint new NFTs for free. This just requires connecting your crypto wallet.

It's simple to create NFTs of digital art, photography, music, video, and more on platforms like OpenSea and Rarible.

Use NFT Tools

Dedicated NFT creator tools are emerging to simplify generating NFTs. For example, Mintable and Lazy let you quickly mint NFTs from assets.

These sites handle the NFT infrastructure so creators can focus on their digital IP.

Write Your Own Smart Contract

If you have blockchain development experience, you can write your own smart contract to issue NFTs. This provides the most control and customization.

Algorithms like Codable can also auto-generate the boilerplate code for you based on your preferences.

Hybrid Approach

A balanced approach is using an NFT marketplace's built-in tools, then displaying your NFT art on your own website. This provides independence while leveraging the marketplace's community.

For example, artist Grimes sold her NFT works through Nifty Gateway but displayed them on her own site.

The Future of NFTs

NFT adoption is still in the early innings, but heading towards mainstream usage and trillion-dollar potential value according to crypto research firm Delphi Digital.

Here are some predicted ways NFTs will evolve next:

  • Celebrity engagement - More celebrities launching branded NFT drops for superfans.
  • Music innovation - Artists using NFTs for new revenue streams like direct fan engagement.
  • Gaming integration - Major gaming publishers will adopt NFTs into flagship titles.
  • Social usage - NFTs for social media engagement, profiles, community benefits, and flexing online.
  • Virtual worlds - NFTs will play a key role in expanding metaverse virtual worlds and economies.
  • Physical asset tokenization - More real-world assets like real estate and luxury goods will be tokenized with NFTs.
