Cryptocurrency Mining Basics

Mining is the process that secures proof-of-work blockchains: machines compete to solve a computational puzzle, and the winner earns the right to append the next block along with the block reward and transaction fees. Understanding it matters even if you never buy hardware, because mining economics drive coin issuance, network security and a large share of sell-side pressure on the market.

The practical questions are less romantic than the concept. Profitability is a function of electricity price, hardware efficiency, network difficulty and coin price — and three of those four move against you over time. Difficulty adjusts upward as competitors join, halvings cut the reward on a fixed schedule, and ASICs depreciate quickly as newer generations ship.

This module covers how proof-of-work actually functions, how mining rigs and pools are structured, what halving does to miner revenue, and how to run the profitability maths honestly before committing to hardware.
