Technical Terms
– Mining: The process of validating and adding transactions to the blockchain, rewarded with Bitcoin.
– Hash Function: A cryptographic function used to secure Bitcoin (e.g., SHA-256).
– Proof-of-Work (PoW): Bitcoin’s consensus mechanism, requiring computational work to add blocks.
– Difficulty Adjustment: A system that recalibrates mining difficulty every 2016 blocks (~2 weeks).
– Block Time: The average time to mine a new block (~10 minutes for Bitcoin).
– UTXO (Unspent Transaction Output): Bitcoin’s system for tracking balances.
– Node: A computer running Bitcoin’s software, maintaining the blockchain.
– Lightning Network: A Layer-2 scaling solution for faster and cheaper Bitcoin transactions.
– Merkle Tree: A structure that summarizes all transactions in a block.

 

Economic Concepts
– 21 Million Cap: The total supply limit of Bitcoin.
– Halving: An event where the mining reward is halved, occurring roughly every 4 years.
– Deflationary: Bitcoin’s supply reduces over time, unlike fiat currencies.
– Store of Value (SoV): Bitcoin as a digital alternative to gold.
– Medium of Exchange (MoE): Bitcoin’s use for transactions.
– Unit of Account (UoA): Pricing goods and services in Bitcoin.
– Digital Gold: A term used to describe Bitcoin as a scarce asset.

 

Privacy and Security
– Private Key: A secret key used to sign transactions and access Bitcoin.
– Public Key: A key derived from the private key, used to receive Bitcoin.
– Address: A shortened version of the public key used to receive payments.
– Seed Phrase: A set of words that can restore a Bitcoin wallet.
– Cold Storage: Storing Bitcoin offline to protect against hacks.
– Multi-Sig (Multi-Signature): A wallet requiring multiple keys for transactions.

 

Bitcoin Ecosystem

– Laser Eyes: A social media trend showing Bitcoin enthusiasm.
– Orange Pill: Convincing someone of Bitcoin’s importance.

 

Advanced Topics
– Taproot: A Bitcoin upgrade improving privacy and efficiency.
– SegWit (Segregated Witness): A scaling solution that separates transaction signatures.
