## Technical Deep Dive: Address Formats and Evolution
Blockchain addresses have evolved to improve security and efficiency:
### Bitcoin Specifics
- Legacy (P2PKH): Starts with 1. (e.g., 1A1zP1eP5...)
- Pay-to-Script-Hash (P2SH): Starts with 3. Used for multi-sig. (e.g., 3J98t1Wp...)
- SegWit (Bech32): Starts with bc1q. Cheaper fees, more efficient. (e.g., bc1qar0s...)
- Taproot (Bech32m): Starts with bc1p. Improved privacy and smart contract capabilities.
### Ethereum Specifics
- Hexadecimal (ERC-20): Starts with 0x. Case-insensitive but uses checksums via capitalization (EIP-55).
### Security Note
Always verify the first and last characters of an address before sending funds. Malware can sometimes swap addresses in your clipboard (Clipboard Hijacking).

💳 Think of it as your digital mailbox number. Anyone can drop money in, but only you have the key to take it out.
