Block Height refers to the total count of blocks added to Bitcoin’s blockchain, reflecting the continuous growth of the network. Each block added represents a new record of transactions, and the chart tracks this growth over time, showing how the blockchain has expanded as more transactions are processed.

The chart visualizes miner revenue from both transaction fees and block rewards. The mining reward decreases by half during each halving event, which occurs approximately every four years.

Hash rate is a critical indicator of network security, mining activity, and overall network health.
