Based on a suggestion made by @petertodd to the -devel mailing list and
the discussion in that thread by him and other participants.
* We've been using the term "consensus", but this commit introduces a
formal definition for it and "consensus rules" as part of the block
chain introduction.
* Describe that consensus rules may change and may happen when they
do: hard or soft forks.
* Describe how full nodes can detect hard or soft forks, then describe
how SPV clients can detect hard and soft forks using the more limited
information available to them.
* Add a short subsection about the different byte orders used with
hashes in Bitcoin Core and other software.
* Re-word some text in other sections to mention the byte order
differences
This commit created based on comments from @SergioDemianLerner (thanks!)
This modifies commits provided by @petertodd to use the terms "pubkey
script" and "signature script" instead of other terms.
* Rename "scriptPubKey" and "output script" to "pubkey script"
(suggested by @luke-jr). We leave a token "scriptPubKey" at the point
where we define pubkey script so that searchers can find it.
* Rename "scriptSig" to "signature script" (suggested by @luke-jr). We
also leave a token "scriptSig" at this definition point.
* Rename "redeemScript" to "redeem script"
* Defined ECDSA on secp256k1 curve as the crypto used in the Transaction
section and added references to secp256k1 private/public keys and
signatures.
* Removed "The Parts Of A Transaction" illustration by commenting it out
in the HTML. Shoehorning the pubkey/signature script terms into this
image was becoming difficult, and I'm not very fond of that
illustration anyway. I'll see if I can think of a nicer replacement
illustration for some point in the future.
* Add a short paraphrased version @petertodd's description of scripts as
generalized crypto.
* Updated all the illustrations which referred to either pubkey scripts
or signature scripts to use these terms.
* Small grammar fixes.
* Lower case #term-scriptPubKey as all our other anchor links are
lower case
* Replace script/scripts with scriptPubKey/scriptPubKeys in
_autocrossref.yaml. (Fixes `make test` errors from broken
auto-crossref links.)
Move existing "regtest / testnet" texts to the new subsection and link to it
Move Bitcoin Core setup instructions in devel-examples
Add a consistent introduction for devel-(guide/ref/examples)
Fix autocrossref.rb to not add links inside {% highlight %} code blocks
* Remove the QR Code error corrections subsection.
* Remove the non-example Payment Protocol text from developer examples.
* Update reference links and autocrossrefs to reflect above deletions
* Fix CSS padding problems reported by @saivann
* Remove all HTML comments from autocrossref text to allow easy checking
for broken link definitions: find _site -name '*.html' | xargs grep '\]\['
* Add PNG versions of guide and example SVG icons. (optipng run)
As suggested by @gmaxwell (thanks!), I tried to make clearer the benefit
of hardened keys:
* Described hardened keys as a solution in the first sentence of the
Hardened Keys subsection.
* Reordered the text so that the problem is described before the
solution, making the presence of a solution clearer.
* Added a prefatory sentence to the description of the two key
derivation formulas again describing the hardened formula as a
solution.
As suggested by @vbuterin (thanks!), I added a paragraph describing that
HD wallets don't use normal derivation on the master key so they don't
have an effective master public key. (See end of the diff.)
This is a fairly large diff because of the reordering, but no new
clauses were added besides those described above.
Thanks also (in alphabetical order) to @cbeams, @mikehearn, and
@tgeller, among others.
