NFTs should be green, too

Non-Fungible Tokens (NFTs) are an invention unique in human history whose role is fast extending beyond the speculative trends around collectibles to use cases that have a positive social impact. Through NFTs, a broad range of physical and virtual assets can be authenticated, providing transparency on ownership and underlying attributes of tokenized assets while preserving the privacy of individual owners. The cryptographic guarantees of NFTs make them well suited for use cases such as anti-counterfeiting, provenance tracking, and title transfer.
