TechnologyReview: In July 2016, someone using the name Tom Elvis Jedusor (the real name of Lord Voldemort, the main villain in the Harry Potter universe, in the French edition) posted a link to a text file in a chat room frequented by Bitcoin researchers. Voldemort’s document described MimbleWimble, a blockchain system that would hide the identifying information associated with Bitcoin transactions.
…The person who started Grin [one of the first new currencies built on a blockchain that implements MimbleWimble] is also pseudonymous, going by the name Ignotus Peverell (the original owner of Harry’s invisibility cloak), and has never been seen. Peverell recently used a text-to-speech program to address attendees at a Grin conference.
So to sum up, Grin is a new currency on the MimbleWimble blockchain imagined by Lord Voldemort and implemented by the invisible Ignotus Peverell.
…Eric Meltzer, an investor for crypto-focused Primitive Ventures, recently estimated that $100 million of “mostly VC money” has already been invested in Grin mining operations.
