Each block contains a cryptographic hash of the previous block’s header. A reward of 50 newly issued coins is given to miners who identify solutions (or hashes) that result in a longer chain. As such, the difficulty of producing a valid proof-of-work increases over time, ensuring that the average time between two blocks remains 10 minutes.

Bitcoin supply

The coin supply is tightly controlled by the underlying protocol. After reaching its maximum total issuance of 21 million coins, no additional Bitcoins can be generated. In this way, the number of Bitcoins that exist is fixed and they cannot be inflated by miners. However, the rate at which new Bitcoins enter circulation does increase due to the halving of the block generation reward.
