NFTs explained to the "moldus": how do these singular certificates of digital objects work?

: -) three small signs on your keyboard that are worth the time to write these lines … $10,000. And it's not over since they're auctioned until September 20, 2021 by the American sales house Heritage auctions.

So you need a key to access the data.
