论文摘要
毫无原则的令牌（NFT）最近成为一种新型区块链托管的金融资产类别，吸引了主要交易量。投资决策依赖于数据以及对分析的足够预处理和应用。这都是由于代币的不可杀菌性质和区块链是主要数据源，NFT交易数据构成了传统财务数据中通常不会遇到的几个挑战。使用包含八个高价值NFT集合的交易历史记录的数据，说明了这些挑战的选择。这些是：代币特征的价格差异，在交易历史上可能存在横向交换和洗涤贸易的可能存在，最后是严重的波动性。尽管本文只是在这种情况下如何应用数据分析的表面，但此处规定的数据和挑战可能会提供有关该主题的未来研究的机会。
Non-fungible tokens (NFT) have recently emerged as a novel blockchain hosted financial asset class that has attracted major transaction volumes. Investment decisions rely on data and adequate preprocessing and application of analytics to them. Both owing to the non-fungible nature of the tokens and to a blockchain being the primary data source, NFT transaction data pose several challenges not commonly encountered in traditional financial data. Using data that consist of the transaction history of eight highly valued NFT collections, a selection of such challenges is illustrated. These are: price differentiation by token traits, the possible existence of lateral swaps and wash trades in the transaction history and finally, severe volatility. While this paper merely scratches the surface of how data analytics can be applied in this context, the data and challenges laid out here may present opportunities for future research on the topic.
