Blockchain NFTs: Understanding the Technology Behind the Trend

Introduction to Blockchain NFTs

Blockchain technology has been making waves in various industries for its immutable, decentralized, and transparent nature. One area where it’s receiving a considerable amount of attention is Non-fungible tokens (NFTs). These tokens are unique, irreplaceable, and indivisible, making them perfect for representing ownership of unique items or assets. As such, understanding the technology behind NFTs is crucial for anyone considering entering this burgeoning market.

What are Blockchain NFTs?

Non-Fungible Tokens (NFTs) are a type of digital asset created using blockchain technology. Unlike cryptocurrencies like Bitcoin or Ethereum, which are fungible and can be exchanged on a like-for-like basis, NFTs are unique. Each NFT has distinct information or attributes that make them irreplaceable and incapable of mutual substitution. You can consider them as digital collectibles that can be bought, sold, and traded on the blockchain.

The Technology Behind NFTs

The technology behind NFTs is blockchain, which ensures the security and immutability of these tokens. But, how does it work?

Ethereum Blockchain and Smart Contracts

Most NFTs are based on the Ethereum blockchain which supports the creation of smart contracts. Smart contracts are self-executing contracts with the terms of agreement directly written into code. They enable the creation of unique tokens with complex attributes – the NFTs. Ethereum’s ERC-721 and ERC-1155 are the standards that allow for the creation of NFTs.

Token Standards: ERC-721 and ERC-1155

ERC-721 is the first standard for representing non-fungible digital assets. Each ERC-721 token is unique and contains distinct information. ERC-1155, on the other hand, is a more advanced standard that allows for the creation of both fungible (identical) and non-fungible (unique) tokens.

How Do NFTs Work?

When an NFT is created or ‘minted’, the unique data of the asset is processed into a hash function, creating an output of a fixed size. This output is stored on a blockchain, usually Ethereum. The hash function ensures that even a small change in the input data leads to a significant change in the output, which helps prevent fraudulent activities.

Once the NFT is minted, it can be bought, sold, or traded on various marketplaces. The record of ownership is also stored on the blockchain, ensuring the verification process is transparent and immutable.

Benefits of NFTs

NFTs are revolutionizing the way we perceive asset ownership. They have several benefits that make them attractive to artists, creators, and collectors:

Provable Ownership

The biggest advantage is the ability to prove ownership. The blockchain records every transaction ever made, making it easy to verify the authenticity and ownership of the NFT.

Monetization of Digital Assets

NFTs have opened up new ways for digital artists and creators to monetize their work. Artists can sell their digital artwork directly to collectors without intermediaries.

Best NFT Platform

There are several platforms where you can create, buy, or sell NFTs. However, not all platforms are created equal. The best NFT platform should offer user-friendliness, a wide range of NFTs, good community engagement, and reasonable fees.


OpenSea is known as the largest marketplace for user-owned digital goods, which includes a wide range of NFTs. Here, you can discover, purchase, or sell any digital asset that is non-fungible.


Rarible is a community-owned NFT marketplace, and it has actively positioned itself at the forefront of the NFT art scene. The platform also offers a ‘Create’ feature which allows any user to mint their own NFTs.


Foundation is a platform that has gained popularity for its focus on digital art. It provides a platform for artists to auction their works as NFTs.


In conclusion, blockchain NFTs are revolutionizing digital ownership, providing new ways for creators to monetize their work and for collectors to prove ownership of unique digital assets. As the technology matures and as more people begin to understand the utility and potentials of NFTs, the demand is likely to increase.

However, like any other emerging market, it’s essential to do your research and be aware of the potential risks. Whether you’re an artist, a collector, or an investor, choosing the best NFT platform can significantly impact your experience in the NFT space. Happy minting!
