    2. 0.4. Not Just About Earning Rewards

Miner refers to an individual or entity that validates transactions and adds new blocks to a blockchain, typically earning cryptocurrency rewards for doing so.

How Miners Keep Blockchains Secure

In proof-of-work (PoW) systems like Bitcoin, miners use computational power to solve complex math problems. The first to solve it gets to add a new block and receive a reward, which includes newly minted coins and transaction fees. This process secures the network, verifies transactions, and prevents fraud like double-spending.

Not Just About Earning Rewards

Miners are essential for the decentralization and security of a blockchain. Without them, public blockchains would be vulnerable to attacks and manipulation.
