How Bitcoin Works
Follow one transaction from a wallet to the mempool, a mined block and final verification.
- Wallets sign; nodes verify; miners order transactions.
- Broadcast is not the same as confirmation.

This path follows a transaction from a wallet into the peer-to-peer network, through node validation, a miner's candidate block, and growing confirmations. It also explains UTXOs, supply, and the halving so the moving parts form one system instead of a list of vocabulary words.
Use the same three checks as you move through the guides. They turn a topic list into a repeatable research process.
Check network claims against consensus documentation and observable node behavior. A block explorer can show a transaction or block, but it does not define validity. Independent nodes running compatible rules decide what they accept, and implementations should be distinguished from the protocol rules they enforce.
Technical explanations often collapse mining, validation, and wallet behavior into one vague process. That makes it easy to overstate what hashrate can control or to mistake an unconfirmed broadcast for settled value. Keep the actor, rule, and time horizon visible.
