The bitcoin blockchain incentivizes miners to complete mathematical hashing functions. Miners who complete more work receive more rewards corresponding to the amount of work. The rewards in a Block are a mixture of un-mined coins and transaction fees. The exact mix of rewards will vary across the different blockchain projects taking into account the parameters of the blockchain and the status of mined vs. unmined coins on that particular chain.
