It costs $1 in bitcoin to receive an in-game life on the SatoshiQuest Minecraft server. From there, you can start looking for bitcoin treasure (equal to 90% of the money collected from all the players) hidden within the blocky simulated world.
The first round of SatoshiQuest began on Jan. 26 and the game resets once treasure has been found. The server checks the bitcoin spot price every 15 minutes, automatically updating the participation fee to keep it at $1.
The project is open source, with the code available on GitHub.
Ninety percent of total game fees go towards the treasury address, with the remaining 10 percent going towards developer costs. After finding the treasure, winners receive 85 percent of the balance, while the remaining 5 percent is kept the wallet until the next round. The reward is only paid out if the treasury wallet balance exceeds the transaction fee.
