Tokens não Fungíveis (NFTs): Criação, Comercialização, Coleta e Análise de Dados na rede Blockchain Ethereum e na Plataforma de Vendas OpenSea

Abstract

The support for smart contracts on the Ethereum blockchain network has enabled the emergence of a new digital market centered around Non-Fungible Tokens (NFTs), unique digital assets that have transformed the way value is assigned and exchanged in the decentralized web.This chapter provides a detailed exploration of three essential aspects that drive the NFT ecosystem: (1) the technical and operational fundamentals of creating and commercializing NFTs, (2) the categorization and automated analysis of collections using the OpenSea API, and (3) the challenges and future opportunities related to scalability, price prediction, and the impact of communities on the NFT market.We present the principles underpinning NFTs, highlighting OpenSea as the largest trading platform for these assets.Subsequently, we discuss data collection and automated categorization techniques, which are crucial for organizing and analyzing the market.Finally, we explore recent research and developments that will address challenges and enhance the growth of the NFT market in the coming years.
