Mining glossary

The words that come up in my videos and guides, each explained in one sentence.

Block: A page of Bitcoin's big ledger. A new one is written roughly every ten minutes.
Fingerprint (hash): A 64-character code computed from the block. Impossible to predict: you have to try.
Difficulty: The number of attempts needed on average to find a block. It adjusts itself every two weeks. Difficulty explained
TH/s, PH/s, EH/s: Attempts per second: a trillion, a quadrillion, a quintillion.
Pool: A server that machines connect to. A regular pool shares the winnings, a solo pool does not. Solo or pool?
Solo: Mining for yourself alone: the whole jackpot, or nothing. Solo mining
Bitaxe: A small open-source Bitcoin miner, perfect to start with. Set it up
Stratum: The language machines and pools speak.
Node: A computer that keeps a full copy of Bitcoin and checks every block.
