Miners are an essential component of every Proof-of-Work (PoW) blockchain consensus protocol, and are responsible for validating new transactions and recording them on the blockchain ledger. Miners validate these transactions by solving complex math problems, which results in the minting of new coins while reinforcing the network's security and trustworthiness. In order to incentivize users to allocate processing power to mine new blocks, miners are typically rewarded a fraction of a network's native currency with every successfully mined block.
