1. What Is Taproot
Taproot is a Bitcoin upgrade (2021) that enhances privacy, scalability, and smart-contract flexibility using Schnorr signatures and Merklized Abstract Syntax Trees (MAST).
2. How It Works
Taproot (BIP 341/342) lets complex spending conditions be hidden behind a single public key; only the used branch is revealed on-chain. Schnorr signatures enable key aggregation (multiple signers look like one). Taproot addresses start with bc1p and enable more efficient multisig and advanced scripts, including inscriptions (Ordinals).
3. Why It Matters
Taproot is Bitcoin's most significant upgrade since SegWit — improving privacy (complex scripts look like simple payments), reducing fees, and opening the door to novel use cases like Ordinals. It demonstrates Bitcoin's capacity for careful, opt-in evolution.
4. Key Facts
- Activated November 2021 via soft fork
- Schnorr signatures aggregate multisig into one signature
- MAST reveals only the used spending path
- Enabled Ordinals inscriptions (2023)
