# Dataset Card for "NFT-70M_image"


## Dataset summary
The *NFT-70M_image* dataset is a companion for our released [**NFT-70M_transactions**](https://huggingface.co/datasets/MLNTeam-Unical/NFT-70M_transactions) dataset, 
which is the largest and most up-to-date collection of Non-Fungible Tokens (NFT) transactions between 2021 and 2023 sourced from [OpenSea](https://opensea.io). 

As we also reported in the  "Data anonymization" section of the dataset card of *NFT-70M_transactions*, 
the URLs of NFT images data were replaced by identifiers to numerical vectors that represent an encrypted representation (i.e., embeddings) 
of the image contents obtained via the [google/vit-base-patch16-224](https://huggingface.co/google/vit-base-patch16-224) neural network model.
