[31] in November 2017, the widely acclaimed blockchain game on Ethereum known as CryptoKitties launched and is credited with pioneering what is considered to be the first bona fide non-fungible token standard, known as ERC-721.
[42] Ultimately, through Entriken's initiative under the moniker "Fulldecent," a vote was held during the paper's drafting phase to decide which word would be used in the published version and "NFT" was chosen by the stakeholders.
[41] While using the standard, CryptoKitties earned the recognition of being the first mainstream NFT dApp;[44] the game's usage was significant enough to have overwhelmed Ethereum's processing power at the time.

[157] According to a report by Chainalysis these types of wash trades are becoming popular among money launderers because of the largely anonymous nature of transactions on NFT marketplaces.
