The NBA and the NBA Players Association is launching NBA Top Shot, a home for blockchain-based digital collectibles.
Supposedly this will allow anyone to purchase a non-fungible ethereum token that represents a video clip of an exciting moment in a game. These moments will serve to let you "own" a piece of the game. Later this will be able to be used in a built in game that focuses on letting people play against one another.
These are always exciting announcements for me. Last year the MLB had announced a similar project with their own NFTs based around special game moments. I've never taken the time to look into them because I'm certainly no Ethereum fan but love the concept. Maybe one day we'll see one of these leagues choose a blockchain that doesn't suck! :P
