Introduction: The advent of the digital age has given rise to many new technologies and opportunities, one of which is Non-Fungible Tokens (NFT). Based on blockchain technology, NFT provide digital assets with unique identities and values, leading to innovations and breakthroughs in the digital art market. Traditional art markets often struggle with copyright disputes and difficulties in tracing the authenticity of artworks. NFT, with the transparency and immutability of blockchain, offer solutions to these issues. Artists can convert their works into NFT and ensure ownership and royalty rights through smart contracts. NFT also offer greater flexibility and convenience for art transactions, contributing to the global growth of the digital art market.

Definition and Principles of NFT 1.1 Definition: A Non-Fungible Token (NFT) is a digital asset based on block chain technology, each with a unique identity and value. Unlike traditional fungible tokens like Bitcoin, NFT are not interchangeable, as each represents a unique digital asset.

1.2 Principles: The core principle of NFT is a decentralized ledger based on blockchain technology, such as the Ethereum blockchain. Each NFT is created and managed through smart contracts, which record the ownership and transaction history of the NFT, ensuring its authenticity and immutability.

NFT' Innovations and Breakthroughs in Digital Art 2.1 Authenticity and Traceability: Traditional art markets often face challenges in verifying the authenticity of artworks. NFT solve this problem through block chain's transparency and immutability. Each NFT contains a unique identifier and metadata, verifying the artwork's authenticity and ensuring its traceability.

2.2 Ownership and Royalty Rights: NFT offer artists a new way to prove ownership and royalty rights for their works. By converting artworks into NFT and managing them through smart contracts, artists can ensure they receive royalties when their works are resold, benefiting more from their creations.

2.3 Growth and Prosperity of the Digital Art Market: The emergence of NFT has given rise to a burgeoning digital art market. Through NFT marketplaces and auction houses, artists can display and sell their works, while collectors and users can choose and purchase digital art they love. This decentralized market model offers greater flexibility and convenience for global digital art transactions and provides more opportunities and exposure for artists and creators.
