Glossary

Hover the headers for quick tooltips, then read the short canonical distinction.

Pseudonymity vs Anonymity

Bitcoin is pseudonymous: addresses are public identifiers without built-in real names, but flows can still be traced and clustered.

Nodes vs Miners

Nodes enforce consensus rules by validating blocks/transactions. Miners order transactions into blocks and compete in proof-of-work.

Wallets vs Keys

Wallets store and manage cryptographic keys used to sign spends. The bitcoin itself exists as UTXOs on the blockchain state.

Base Layer vs Lightning

Bitcoin base layer optimizes final settlement and security. Lightning optimizes speed and cost for day-to-day payment flow.

Bitcoin Academy Learning Paths

Structured concept nodes connect blocks, transactions, mempool policy, mining incentives, and security models into guided journeys you can resume anytime.

Each node links to live explorer modules and labs so theory maps directly to observable mainnet behavior.
