Study Notes
Bitcoin Introduction
- Bitcoin is a decentralized digital currency, operating without a central authority (like a bank).
- Introduced in 2009 by Satoshi Nakamoto.
- Relies on blockchain technology for transparent and immutable transaction records.
- Key Concepts: Decentralization (no single entity controls it), peer-to-peer network (transactions directly between users).
Bitcoin's Structure and Function
- Blockchain: A distributed ledger where transactions are grouped into blocks, linked chronologically. Each block includes a list of verified transactions and a reference to the previous block.
- Mining: The process of validating transactions and adding new blocks to the blockchain. Miners solve cryptographic puzzles for rewards (new Bitcoins).
-
Bitcoin Wallets: Used to store and manage Bitcoin.
- Hot Wallets: Online wallets connected to the internet.
- Cold Wallets: Offline wallets (e.g., hardware wallets, paper wallets), considered more secure.
-
Keys:
- Public Key: Shared to receive Bitcoin.
- Private Key: Kept secret for accessing and sending Bitcoin.
