What is NFT Metadata and How Does It Work (2025)
The core components and importance of NFT Metadata
The metadata of non-fungible tokens (NFTs) is a key set of information that describes their uniqueness and value. This metadata typically includes images, attributes, characteristics, names, total supply, and historical information. As the NFT market continues to evolve, the accuracy and completeness of metadata are becoming increasingly important, as they directly affect the authenticity and market value of NFTs.
Significant advancements in NFT metadata technology in 2025
By 2025, NFT metadata technology has made significant progress, mainly reflected in the following aspects:
Improved IPFS content verification IPFS (InterPlanetary File System) plays an important role in the storage of NFT Metadata as a decentralized storage protocol. In 2025, the IPFS content verification mechanism was significantly improved, allowing digital assets to be better authenticated. This improvement not only enhanced the reliability of the data but also increased user trust in the authenticity of NFTs.
Reduction of storage costs Through advanced compression technology, the storage cost of NFT metadata has been reduced by approximately 40%. This enables more creators and developers to store and manage NFT metadata at a lower cost, thereby promoting the further development of the NFT market.
Cross-chain compatibility standard In 2025, the introduction of cross-chain metadata compatibility standards enabled NFTs to be seamlessly transferred across different blockchains. The implementation of this standard greatly enhanced the liquidity and interoperability of NFTs, allowing users to manage and trade their digital assets more flexibly.
AI-driven Metadata verification tool The application of artificial intelligence technology in NFT metadata verification is becoming increasingly widespread. In 2025, many platforms began to integrate AI-driven metadata verification tools to detect fraudulent NFTs. These tools can identify potential fraudulent activities by analyzing various characteristics of the metadata, thus protecting users’ interests.
The popularization of standardized metadata formats.
Currently, more than 70% of new NFT projects have implemented standardized metadata formats. This standardization not only simplifies the creation and management process of NFTs but also enhances the transparency and credibility of the NFT market. The standardized metadata format allows different platforms and markets to more easily share and exchange NFT information, thereby promoting the overall development of the market.
Enhanced extensions of ERC-721 and ERC-1155
ERC-721 and ERC-1155 are two widely used NFT standards. In 2025, these standards were enhanced through new extensions, providing creators with more features and flexibility. These extensions allow for dynamic Metadata updates while maintaining the integrity of the original asset. This means that the Metadata of an NFT can be updated over time and in response to market demands, making NFTs more dynamic and adaptable.
Comparison and Selection of Storage Methods
There are mainly three methods for storing NFT metadata: IPFS, on-chain storage, and hybrid storage. Each method has its advantages and disadvantages, suitable for different scenarios and needs.
| Storage Method | Usage Rate | Average Cost | Advantages | Disadvantages |
|---|---|---|---|---|
| IPFS | 65% | Lower | Decentralization, high reliability | Depend on network nodes |
| On-chain | 20% | higher | High security, directly stored on the blockchain | High cost, limited storage space |
| Mix | 15% | Medium | Combining the advantages of IPFS and on-chain storage | Manage complexity |
