TOKYO -- Last year, Australian gaming startup Immutable sold its first batch of digital monsters, pets and warriors -- characters with names like Chieftain of the Deadlands or the Exiled Necromancer -- based on an upcoming role playing game called Guild of Guardians.
Players would not only be able to take the characters to dungeons to complete tasks when the game launches, but also trade them like collectibles, since they were non-fungible tokens, or NFTs: digital assets based on blockchain technology.
