Binary and Hexadecimal in Bitcoin
Bitcoin, like all digital systems, fundamentally operates on binary (base-2) numbers. Hexadecimal (base-16) is often used as a shorthand for binary because it provides a more compact way to represent binary data, making it easier for humans to read and work with.

Practical Applications in Bitcoin
- Addresses: Bitcoin addresses are derived from public keys and often represented in Base58, but the underlying data is binary.
- Transaction Data: Raw Bitcoin transactions are typically displayed in hexadecimal format for easier reading.
- Mining: Miners are essentially trying to find a specific binary number (hash) that starts with a certain number of zeros.
