This was the initial theory for this section:
- New Section X.1: Understanding Schnorr Signatures
- New Subsection: Understanding the Math of Schnorr
- Explanation: Add + subtract for one signature
- New Subsection: Supporting MuSig
- New Subsection: Understanding the Use of Adapter Signatures
- New Subsection: Knowing the Advantages of Schnorr
- Explanation: size, 64 bytes vs 72, better for multisigs
- Explanation: speed, linear, validate a million-sig multisig in 2 minutes
- Explanation: privacy, no difference between MuSig and sig, no detection of Lightning
- Explanation: also better security, non-malleability
- Reference: https://github.com/bitcoin/bips/blob/master/bip-0340.mediawiki
- New Subsection: Understanding the Math of Schnorr
- New Section X.2: Using Schnorr Signatures
- New Subsection: Signing with Schnorr
- New Subsection: Adding a Schnorr Signature
- New Subsection: Reading a Schnorr Signature
- New Subsection: Using Schnorr with Taproot
- Update Chapter 6 (Multisigs) to Integrate with Schnorr [this might be another section]
We also may want some of this:
Chapter Y: Improving Bitcoin Scripts with Taproot (probably between chapters 13+14, possibly expanding to two chapters)
- New Section Y.1: Understanding MAST
- New Subsection: Improving Privacy with MAST
- New Subsection: Laying out a Script in MAST
- New Subsection: Knowing the Advantages of MAST
- Explanation: larger scripts
- Explanation: hidden branches of scripts
- Explanation: fungibility
- https://github.com/bitcoin/bips/blob/master/bip-0114.mediawiki
- New Section Y.2: Understanding Taproot
- New Subsection: Integrating MAST with Taproot
- Explanation: Expanding Segwit
- Explanation: Integrating Schnorr Signatures
- New Subsection: KNowing the Advantages of Taproot

- New Subsection: Making a Taproot Payment
- New Subsection: Validating a Taproot Script
- Update Chapter 9 to Integrate with Taproot
- Mention Taproot in 9.1 or 9.2
- Add New Section 9.6: Scripting a P2TR (mostly a pointer to Chapter Y)
