Mimblewimble paper announced on IRC 📢

On August 2nd 2016 an anonymous user by the pseudonym “Tom Elvis Jedusor” (Voldemort in the French version of Harry Potter) logs into the bitcoin-wizards irc channel and drops the paper “MIMBLEWIMBLE”. In this paper “Tom Elvis Jedusor” proposes “an idea for improving the privacy in bitcoin”.

In the paper s/he explains why it’s called Mimblewimble “because it is used to prevent the blockchain from talking about all user’s information”, Mimblewimble is a tongue tying curse in Harry Potter “Mimblewimble, which prevents your opponent from accurately casting their next spell”.
