Most Proof of Work networks (like Bitcoin) have a finite number of coins. Once a pre-determined quantity of coins are mined, no more are introduced to the market.

This is very different from the traditional economic system. Governments have the power to print more money when they want to. This can lead to inflation. But in decentralized networks like Bitcoin, new coins are limited by the underlying code. 

The new coins are distributed to the miners who support the network by validating transactions with their hashing power. This process is called mining.

Bitcoin mining is the process of verifying bitcoin transactions and adding those transactions to the bitcoin blockchain. Miners are an integral part of the bitcoin network, helping to ensure the security, stability, and decentralization of the blockchain.
