Understanding Blockchains for Non-Fungible Token (NFT) Development

Explore the top blockchains for NFTs, including Ethereum, Solana, and Cardano, and learn how to select the best platform for your NFT project.

Key Takeaways

NFTs use unique metadata to represent ownership, rarity, and other asset attributes.
Major blockchain platforms for NFTs include Bitcoin, Ethereum, Solana, Polygon, and more, each offering distinct advantages.
Selecting the right blockchain for NFT projects impacts transaction costs, speed, and market accessibility.

Non-fungible tokens (NFTs) have emerged as one of the most notable applications of blockchain technology, providing a framework to display and trade ownership of both digital and physical items. But how exactly do NFTs function?

What Makes NFTs Unique?

Unlike ordinary digital images, NFTs are accompanied by specific metadata that imbues them with unique properties. This metadata serves as a digital identifier that showcases ownership, rarity, and other essential characteristics relevant to modern digital and physical goods. Minting an NFT involves embedding this metadata as a unique cryptographic token onto an active blockchain, a process often referred to as "minting."

NFT Blockchains vs. NFT Marketplaces

Blockchains serve as the backbone of NFTs, lending them the qualities of immutability, verifiability, and distinctness. These characteristics enable NFTs to validate ownership across various sectors—including art, intellectual property, real estate, and collectibles. Users can engage with NFT marketplaces that facilitate the creation, minting, purchase, and sale of NFTs, allowing creators to easily reach their target audiences.

Let’s delve into some of the leading blockchains making waves in the NFT landscape.

Bitcoin: The Original Blockchain

While Bitcoin was designed primarily for peer-to-peer (P2P) transactions, the Bitcoin Ordinals protocol adds a fascinating dimension by allowing users to inscribe data such as images and videos onto satoshis, Bitcoin's smallest unit. It uses advancements like the Taproot upgrade, which enhances transaction efficiency and privacy, alongside Segregated Witness (SegWit), which boosts block capacity. As of November 2023, the Ordinals protocol surpassed 41 million inscriptions, leading to a significant spike in Bitcoin transaction fees, rising nearly 1,400%.

Notably, the cost of inscribing ordinals can be steep—inscribing a 20-kilobyte image could set users back between $150 and $250 and may take around half an hour.

Ethereum: The Front-Runner

Ethereum has drastically transformed the NFT space since the introduction of the ERC-721 standard, which laid the groundwork for smart contract-based NFTs. The platform became a bastion for NFT utilities across various domains, including gaming and music.

In 2017, Ethereum introduced the ERC-1155 standard, allowing multiple token types to be executed under a single smart contract, thus streamlining processes and minimizing transaction costs. In 2023, Ethereum retained 72.3% of the NFT market share, translating to a trading volume of $8.54 billion. However, its dominance has seen a decline from over 90%, with rising competitors like Bitcoin and Solana.

The recent Dencun upgrade may affect Ethereum’s gas fees indirectly, which could either incentivize or discourage NFT transactions based on costs. Notably, layer 2 solutions may gain traction, taking advantage of improved operational efficiency.

Solana: The Efficient Challenger

Solana ranks third in the NFT space, capturing 7.4% of the market share. Its architecture allows for high throughput and minimal transaction costs, primarily driven by its use of stateless smart contracts, which expedite processing. Solana’s unique combination of proof-of-stake (PoS) and proof-of-history mechanisms enables it to promise censorship resistance and attract a broad array of NFT artists and traders. Transaction fees are set extremely low at 0.000005 SOL.

Polygon: Layer 2 Solution for Ethereum

Previously known as Matic, Polygon is a layer 2 scalability solution that functions atop the Ethereum mainnet. It aims to reduce costs and enhance processing speeds significantly. Polygon can handle up to 65,000 transactions per second (TPS), compared to Ethereum’s theoretical maximum of 100,000 TPS. Users appreciate Polygon for requiring no upfront minting costs, though a nominal 2.5% service fee applies when selling new NFTs.

Cardano: Addressing Previous Generations' Limitations

Cardano operates as a third-generation PoS blockchain, addressing challenges faced by both Bitcoin and Ethereum. Minting on Cardano can involve using third-party services or self-minting, giving users added control over their tokens. Transaction fees vary based on file size, which can be beneficial for users looking to keep costs low.

BNB Chain: Fast and Cross-Chain Compatible

The BNB Chain consists of the BNB Beacon Chain and the BNB Smart Chain, both influencing NFT creation with their lower costs and faster speeds. Developers favor BNB Smart Chain for its affordability and cross-chain compatibility, requiring only 0.005 BNB for NFT minting.

Tezos: An Eco-Friendly Alternative

Tezos employs the TZIP-012 standard for NFT storage, offering an eco-friendly option in the NFT market. It enables users to mint single and multi-token smart contracts, supported by the community-focused approach towards digital art. The FA2 standard ensures compatibility with multiple wallet and third-party solutions.

Tron: Seeking Efficiency

Tron uses the TRC-721 standard for NFT issuance, focusing on improving network performance. While operating similar to Ethereum's ERC-721, Tron requires users to set up a wallet with at least 350 TRX as a balance to create NFTs.

Navigating NFT Blockchain Options

With numerous blockchain options available for NFT development, choosing the right one is essential. Key criteria for selecting a blockchain include:

Future-proofing
Fast transaction capabilities
Low gas and transaction fees
A thriving market for reselling NFTs
Strong IP governance
Established partnerships
Cross-platform compatibility

Finding a blockchain that meets these requirements is crucial for ensuring the long-term success of any NFT project.
