A new alternate reality game called ‘Satoshi’s Treasure’ promises $1 million in bitcoin to the first player to locate 400 hidden keys to a wallet containing that sum. One of the game’s co-creators, Eric Meltzer, announced the game to Coindesk yesterday. The first clue of the game was also released yesterday on Twitter, instructing players to travel to locations spanning four continents.
The production is a team effort by 20 developers, with the aim being to ensure no individual knows all the clues. The secret key consists of 1,000 parts, although only 400 will be needed to reconstruct the whole key and access the wallet. The system uses an algorithm called Shamir’s Secret Sharing, which allows a secret to be accessed by someone possessing a certain “threshold” number of its parts.
