There are 12 different types of planets. You will use the Proof-Of-Work consensus algorithm to mine them. The process is basically what Bitcoin and Ethereum miners do: finding a hash based on the last mined token hash and your own unique address. This hash should meet a certain criteria. The difficulty and cost to mine is determined by a number of planets in existence. Every time planet count doubles or is halved, mint cost and difficulty will also be double or halved respectively. The mining process will be run on your browser. The early ones should be mined in a few seconds.
