Evidence: 100 • authority: 72

A non-fungible token (NFT) is a unique digital identifier that is recorded on a blockchain and is used to certify ownership and authenticity. They typically contain references to digital files such as artworks, photos, videos, and audio. Because NFTs are uniquely identifiable, they differ from cryptocurrencies (which are fungible, hence the name non-fungible token), and as a result they cannot be copied, substituted, or subdivided. Their ownership can be transferred by the owner, allowing NFTs to be sold and traded. Initially pitched in 2017 as a new class of investment asset, NFT trading increased from US$82 million in 2020 to US$17 billion in 2021. Its market was occasionally compared to…

A Survey: Security, Transparency, and Scalability Issues of NFT's and Its Marketplaces.. Non-fungible Tokens (NFTs) are ownership records stored on a blockchain, and they are typically digital items such as photos and videos. In many ways, an NFT is like a conventional proof-of-purchase document, such as a paper invoice or an electronic receipt. NFTs are attractive among other things because of verifiability; each sale is recorded as a blockchain transaction, allowing ownership to be tracked. Also, NFTs can be used to transfer digital assets between two mutually distrusting parties, since both the crypto payment and the asset transfer take place in one transaction. With NFTs, all marketplac…

A non-fungible token (NFT)-Based framework for antenatal care in resource-constrained settings.. Background In many low-resource settings, maternal health records are paper-based, fragmented, and predominantly controlled by institutions. These conditions limit patient agency, disrupt continuity of care, and constrain the efficiency of service delivery. Objective This study examines the potential of blockchain technology, specifically non-fungible tokens (NFTs), to support a patient-centred approach to antenatal and postnatal record management. Methods Drawing on Actor-Network Theory (ANT), we conducted a qualitative case study involving eight semi-structured stakeholder interviews at primar…

Innovative integration of biometric data and blockchain to enhance ownership and trust with NFTs.. Biometric data has the potential to revolutionize health analytics and pharmacology by providing personalized insights into drug efficacy and health trajectories. However, its governance presents significant ethical challenges, particularly around individual ownership and privacy. This study addresses these challenges by proposing a sustainable and ethical framework that integrates biometric data with non-fungible tokens (NFTs). We developed a customized NFT framework with advanced smart contract functionalities that enhance privacy protection and decentralized authentication of biometric data…

Price prediction of PFP NFT based on the sentiments of users in posts on social media.. With the introduction of blockchain technology and the emergence of non-fungible tokens (NFTs), users can prove ownership of digital content by cryptographically tokenizing the content they create, and it becomes possible to trade digital content. As user-generated digital content is frequently traded online, many scholars have analyzed the factors of user transactions, but there is a limitation that they have not been able to analyze the direct relationship between the sentiments of users and price. Therefore, this study uses multi-layer perceptron so as to analyze the factors that affect the price of p…
