 # 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 neural network models.
