Different Types of Bitcoin Address:
Bitcoin Address Formats (Derivation Paths) Explained
Bitcoin address formats have evolved over the years. Each new format improves privacy, lowers fees, or adds functionality. Here’s every type you’ll still encounter today — and which one you should use.
Common Derivation Path Mistakes
- Never writing down the derivation path
- Assuming all wallets work the same
- Using different paths thinking they’re connected
- KISS (knot keeping it simple)
- Thinking you need every technical detail
Legacy m/44′ (P2PKH) – Starts with “1”
- Example: 1BoatSLRHtKNngkdXEeobR76b53LETtpyT
- Oldest format (2009)
- Highest on-chain fees
- Worst privacy (transparent reuse)
- Still widely supported, but avoid for new wallets
Nested SegWit m/49′ (P2SH) – Starts with “3”
- Example: 3EktnHQD7RiAE6uzMj2ZifT9YgRrkSgzQX
- Wraps SegWit inside legacy format
- Lower fees than Legacy
- Better exchange and hardware wallet support in early days
- Transitional format – rarely chosen today
Native SegWit m/84′ (Bech32) – Starts with “bc1q”
- Example: bc1qar0srrr7xfkvy5l643lydnw9re59gtzzwf5mdq
- Introduced in 2017 (BIP-173)
- Lowest on-chain fees (up to 30-40% cheaper)
- All lowercase, error-detecting code
- Excellent privacy when you use fresh addresses
- Best choice for most users in 2025
Taproot m/86 (Bech32m) – Starts with “bc1p”
- Example: bc1pmfr3p9j00pfxjh0z0r09fhqxnnufcvd274a8df5n2d2d8s7a355q0h8w2h
- Activated November 2021 (BIP-341)
- Even better privacy (looks identical to single-sig spends)
- Enables advanced smart contracts and multisig that stay cheap
- Future-proof format – now fully supported by major wallets
Multisig m/45′ or m/48′ – Uses P2SH m/45′ (P2SH Multisig) – Starts with “3”; P2WSH m/48′ (Native SegWit Multisig) – Starts with “bc1q” (longer, 42 chars); or Taproot m/86′ (P2TR Multisig) – Starts with “bc1p”
- Example (P2SH): 3QJmV3qfvL9SuYo34YihAf3sRCW3qSinyC Example (P2WSH): bc1qqqqsyqcyq5rqwzqfpg9v39mu2zzuuq4zruyut99ssp30vwrtvgqmmmjz6q Example (Taproot): bc1pmfr3p9j00pfxjh0z0r09fhqxnnufcvd274a8df5n2d2d8s7a355q0h8w2h (can hide multisig nature)
- Introduced in 2012 (BIP-16 for P2SH); SegWit multisig in 2017; Taproot enhancements in 2021
- Fees vary by type: P2SH higher (similar to Nested SegWit); P2WSH lower (like Native SegWit, 20-30% savings); Taproot lowest for complex multisig (efficient scripting)
- Excellent privacy in Taproot (spends look like single-sig, no script reveal until spend); P2WSH/P2SH reveal multisig on spend, potential privacy leak if reused
- Requires multiple keys (e.g., 2-of-3) for security; widely supported in hardware wallets (Ledger, Trezor) and software (Electrum, Sparrow); ideal for shared control or inheritance; use Taproot version for modern setups in 2026
Quick 2026 Recommendation:
- Daily spending & receiving → Use Native SegWit (bc1q…)
- Maximum privacy & future features → Switch to Taproot (bc1p…)
- Sending to old services → They still accept everything, but you pay more if you use Legacy
Pro tip: Modern wallets like Sparrow, BlueWallet, Electrum, and most hardware devices let you create all formats. Always pick bc1q or bc1p for new addresses — save money and protect your privacy from day one. Start using the latest Bitcoin address formats today and keep more sats in your pocket!
