The rapid expansion of the non-fungible token (NFT) market has opened new avenues for artists, collectors, and investors. However, it has simultaneously exposed significant vulnerabilities related to the storage, verification, and distribution of associated metadata. This paper provides an in-depth examination of the existing NFT metadata storage landscape, revealing a predominant reliance on centralized platforms, which introduces risks concerning the integrity, security, and long-term preservation of these digital assets. Through a comprehensive analysis of the top-selling NFTs on the OpenSea marketplace, the study shows that a considerable proportion of metadata is hosted on centralized servers, rendering it susceptible to censorship, unauthorized modifications, and data loss due to server outages or breaches. In contrast, decentralized storage solutions, particularly those utilizing the InterPlanetary File System (IPFS), present a more resilient and tamper-resistant alternative. These systems offer enhanced security, transparency, and greater autonomy for creators and collectors by enabling distributed metadata storage. This paper proposes the widespread integration of decentralized architectures incorporating cryptographic techniques, such as digital signatures and hash functions, to authenticate ownership and ensure the immutability of metadata. These findings underscore the critical importance of decentralized methodologies to preserve NFTs’ value, trustworthiness, and decentralized ethos, ensuring their sustainability in the digital economy.
