Miners process transactions on the Monero network by @mining blocks. The miner of a @block is paid the constant block reward of .6 XMR, and the @transaction fees of the users who have transactions in that block. Monero has the block reward rather than relying solely on the transaction fees to give the miners incentive to keep securing the network with their hashrate, and keep transaction fees low.
The @tail-emission caused by this constant block reward creates an inflation rate of less than 1% which trends towards 0% over time. The fixed emission of the currency ensures human corruption cannot over inflate the supply. Keeping the network predictable, decentralized, and secure.
