- Drop soon-to-be-outdated mention of current block reward amount
- Aezeed: mention internal and external version sumbers. Instead of
saying "global word list", clarify that both the backup and the
recovery software need to support the same word list.
- Mention that compact block filters are something that blocks might
commit to in the future in a consensus-enforced way.
- Add links to both RGB and Taproot Assets documentation.
- Mention that taproot assets can also support native forwarding.
- Minor edits and add some FIXMEs for later changes.
- Drop box with Wikipedia definition of digital signatures. It didn't
add anything and its accuracy was debatable.
- Use "commitment hash" earlier and more often.
- Fix some variable-name errors in the math
- Correct info about worst-case signature verification cost
- "Ephemeral key pair" -> nonce; makes it consistent with schnorr
section and better composes with section about avoiding nonce reuse
- Changed variables to be consistent with schnorr section
