Part 4/12:
Each block on the Bitcoin blockchain principally contains transaction data, allowing around 2,000 transactions to fit into a single block. New blocks are generated roughly every ten minutes, leading to a processing speed of about three transactions per second. Blocks also maintain a reference to their predecessors, ensuring the blockchain's integrity and immutability.
With this understanding, questions naturally arise: How does one ensure the legitimacy of new BTC transactions? How are new BTC coins generated? And why would anyone want to invest resources in processing these transactions? Mining serves as the answer to these queries.
