It is common to make a distinction between account-based and token-based digital currencies, as in this report from the Committee on Payments and Market Infrastructures (on which some of us collaborated), this working paper from the Bank of Canada, this staff discussion note from the International Monetary Fund, and this note from the Bank for International Settlements, among many other sources. In all of these papers, the distinction the authors make is that an account-based system requires verifying the identity of the payer, while a token-based system requires verifying the validity of the object used to pay.

According to Ashish Chauhan in The Times of India, a group of farmers in the Gujarat region were able to put together fake matches for the very real Indian Premier Cricket League. The “players” were given scripts to follow and the whole thing was broadcast on YouTube with commentators who sounded exactly like the IPL’s familiar voices.
