Tokenization, the representation of just about anything as a discrete digital entity, is making it possible to turn both tangible and intangible things into liquid assets. Tokens tend to be associated in the public imagination with the blockchain, but conventional technologies can also support them. Non-fungible tokens (NFTs) arguably remain the best-known such tokenized assets, even if the bull market that saw some of them earn their owners spectacular returns has passed. But other digital assets, including digital versions of national fiat currencies, are gathering momentum.
