An attempt to incorporate NFTs throws a wrench into a $40 million domain name auction

Frank Schilling, founder of the Uni Naming & Registry (UNR) held an auction for 23 TLDs (the bit at the end of the domain, like .com or .org). These included .link, .help, .game, and even .christmas. The April auction grossed more than $40 million, but as of mid-December the transactions had not been completed. This is because UNR attempted to add some marketing flair to the auction by including NFTs for each of the TLDs, to go to the auction winners. ICANN, the group responsible for much of the domain world, objected to and withheld consent for the transactions, writing "we sought to understand the impact of the transactions on the Domain Name System ('DNS'), including how Non-Fungible Tokens (NFTs) created on the Ethereum Name Service (ENS) were being used, and were involved in the transactions. ICANN repeatedly asked UNR for documentation or other information related to NFTs in the hopes that UNR would provide fulsome and complete responses."
