Quick Answer
Mining is how new bitcoin is created and how the network agrees on history. Miners burn electricity to win a global guessing game; the winner writes the next block and is paid in fresh bitcoin. It sounds wasteful, but that cost is exactly what makes Bitcoin secure.
💡 Think of it as…
සෑම මිනිත්තු දහයකට වරක් ක්රියාත්මක වන ලෝක ව්යාප්ත ලොතරැයියක්, ප්රවේශපත්ර මිලදී ගැනීම යනු ට්රිලියන ගණන් අනුමාන කිරීමට විදුලිය වැය කිරීමයි. ඔබ වැඩි ප්රවේශපත්ර මිලදී ගන්නා තරමට, ඔබේ අවාසිය යහපත් වේ - සහ ජයග්රාහකයා ඊළඟ පිටුව ලෙජරයට එක් කිරීමට සහ ත්යාගය ලබා ගැනීමට අයිතිය උපයා ගනී.
The puzzle (Proof of Work)
Miners repeatedly hash a candidate block, changing one number, until they find a hash below a target value. There is no shortcut — only brute-force guessing. Finding a valid hash proves real work and energy were spent.
The block reward & fees
The winning miner earns the block subsidy (newly minted bitcoin) plus the fees of the transactions they include. The subsidy halves roughly every four years — the "halving" — slowly capping supply at 21 million coins.
Difficulty adjustment
Every ~2 weeks the network automatically retunes the puzzle’s difficulty so blocks keep arriving about every 10 minutes, no matter how much mining power joins or leaves. This self-balancing is one of Bitcoin’s quiet masterstrokes.
🔑 Key takeaway
Mining secures Bitcoin by making it expensive to write history and impossible to fake cheaply. Energy in, security and new coins out.

නිතර අසන ප්රශ්න
Can I still mine Bitcoin at home?▼
Profitably, almost never with a laptop or PC. Modern mining needs specialized ASIC machines and very cheap electricity. Most people are better off simply buying Bitcoin.
Is Bitcoin mining bad for the environment?▼
It uses significant energy, but a growing share comes from stranded, surplus, or renewable sources, and miners increasingly monetize energy that would otherwise be wasted. It is a genuine and nuanced debate.
What happens when all 21 million are mined?▼
New issuance ends around the year 2140; miners will then be paid entirely by transaction fees. Most coins are already mined today.
