Mining
There is a real Bitcoin miner humming away in the shop. This is what it is doing, in plain English.
What Mining Actually Is
Mining is how new Bitcoin transactions get written into the record. Roughly every ten minutes, miners around the world compete to add the next page - called a block - to Bitcoin's shared ledger.
The competition is simple: do a huge amount of guessing work, and prove you did it. That proof is expensive to fake, which is exactly the point. Nobody gets to rewrite history without redoing all that work.
Our miner is a small one. It almost certainly will not win a block - but it plays the same game as the big players, and it makes the whole idea real instead of abstract.

Normal money needs a trusted third party - a bank or a payment company - to keep the ledger honest. Bitcoin has no such referee. Instead, proof of work secures the network.
Because adding a block costs real electricity and real effort, cheating becomes absurdly expensive. To undo a payment, an attacker would need to out-work the entire global network - and keep out-working it.
Mining turns raw energy into trust. That is the trade: no bank, no permission, no single point of failure - just maths and work that anyone can verify.

How It Works
No maths degree needed. The whole game is guess, check, win.
Guess A Number
Miners bundle waiting transactions into a block, then race to find a lucky number called the nonce. There is no shortcut - just billions of guesses per second.
Beat The Target
Each guess is run through a hash function. If the result lands below the network's difficulty target, the block is valid. Think of it as rolling a near-impossible dice roll.
Win The Reward
The winning miner adds the block to the chain and collects the block reward plus fees. Then everyone starts again on the next block.
On average a block is found every ten minutes. If miners join and blocks come too fast, the difficulty rises; if they leave, it falls. The network self-corrects, forever.

How many guesses per second a miner, or the whole network, can make.
BitictionaryDifficulty
How hard the guessing game is. It adjusts every two weeks to keep blocks near ten minutes.
BitictionaryBlock Reward
The new bitcoin plus fees paid to whoever finds a valid block. Currently 3.125 BTC.
BitictionaryHalving
Every four years the block reward is cut in half - that is how the 21 million cap holds.
