- Provide rough block and year when 99% of all BTC will have been mined
- Remove user-stories section. I think this section frontloaded too
much irrelevant detail. In new sections of this edition, I've
exclusively used the convential Alice, Bob, Carol, etc.---without
trying to maintain a consistent backstory. This is simpler on the
writer and, I think, simpler on the reader---if they jump into a
section of the book, they don't need to worry that there's some
important context in a previous section.
- This also necessitated a few changes chapter 2.
- Mostly remove the phrase "custody". Instead use the phares "control
the key". I think this is clearer to non-specialists and a quick grep
shows that we don't use any version of the word "custody" elsewhere in
the book.
- Drop localbitcoins.com. This service was terminated after this
chapter was updated.
- Add 'feerate' to the script for catching forbidden words. :-( This
required a change to a comment in an image source.
- Other minor changes and typo fixes
