In the cryptocurrency world, wallet addresses function like "bank account numbers" or "shipping addresses." Every transaction requires them. With the emergence of the Ordinals protocol, Bitcoin's adoption of SegWit (Segregated Witness) and Taproot upgrades has surged. This introduced many users to unique address formats like "bc1p" for the first time.
But how many Bitcoin address formats exist, and what are their characteristics? Let's explore.
What Is a Bitcoin Address?
A Bitcoin address is used to send and receive Bitcoin, similar to a traditional bank account number. Anyone with your Bitcoin address can send you funds, and you can transfer Bitcoin to other addresses.
Bitcoin addresses are alphanumeric strings. Here are a few examples:
Legacy (P2PKH): Starts with
1(e.g.,1A1zP1eP5QGefi2DMPTfTL5SLmv7DivfNa)- The original Bitcoin address format.
- Less efficient due to larger transaction sizes.
SegWit (P2SH): Starts with
3(e.g.,3FZbgi29cpjq2GjdwV8eyHuJJnkLtktZc5)- Improves scalability by reducing transaction size.
- Compatible with older wallets.
Native SegWit (Bech32): Starts with
bc1q(e.g.,bc1qar0srrr7xfkvy5l643lydnw9re59gtzzwf5mdq)- Most efficient format with lower fees.
- Supports advanced features like Taproot.
Taproot (Bech32m): Starts with
bc1p(e.g.,bc1p5d7rjq7g6rdk2yhzks9smlaqtedr4dekq08ge)- Enhances privacy and smart contract flexibility.
- Introduced with Bitcoin’s Taproot upgrade.

Why Do Different Address Formats Exist?
Bitcoin evolves to improve efficiency, security, and functionality. New formats address limitations of older ones, such as:
- Transaction Fees: Native SegWit and Taproot reduce fees by optimizing data storage.
- Privacy: Taproot obscures complex transactions, making them indistinguishable from simple ones.
- Compatibility: P2SH ensures backward compatibility with non-upgraded wallets.
FAQ: Bitcoin Addresses
Q: Can I send Bitcoin between different address formats?
A: Yes! Transactions between formats (e.g., Legacy → SegWit) are seamless. The sender’s wallet handles conversion.
Q: Which format is the best?
A: Native SegWit (bc1q) and Taproot (bc1p) offer the lowest fees and future-proofing. Legacy addresses are outdated but still functional.
Q: Are Bitcoin addresses case-sensitive?
A: No. "1A1z..." and "1a1Z..." refer to the same address. However, always copy/paste to avoid errors.
