Dutch artist Dadara and digital rights management platform RAIRtech have developed a collection of 7.9 billion identical nonfungible tokens (NFTs).
The collection, named CryptoGreymen, is on the Polygon (MATIC) Ethereum scaling network. Although each NFT is identical, they will be assigned a serial number of up to 7.9 billion to reflect the number of humans currently estimated to be living on the Earth.
