- Describe topological order to help readers understand how that solves
the double spend problem
- Mention that transactions can be safely relayed one block before their
locktime allows them to be included in a block because they'll be
valid next block.
- Be a bit clearer about when subsidy becomes zero due to rounding and
when BIP42 makes it zero unconditionally.
- Describe the creation of the witness merkle root before the block
header merkle root
- Move up note about the retarget off-by-one bug
- Make "best blockchain" an inherent property and not an alias for a
current chain. When a new block arrives that triggers a reorg, we
don't switch best blockchains---the new chain is the best blockchain
and we switch to using it.
- Combine two sections about forks that were repetitive
- Mention that pool miners also need to prove they paid the pool's
preferred coinbase transaction template
- Add a todo to clarify terminology around the 51% attack. The existing
text used this in a way that's consistent with how it was used in
early Bitcoin history, but it's potentially confusing because it
doesn't actually require a majority of hashrate to make the attack and
it confuses it with a censorship attack that does require a majority
(or at least a selfishing mining minority) to maintain.
- Reduce the situations we describe as "double spends". Consensus
prevents double spending within a valid chain; the other situations
are about unconfirmed transactions, which might better be described
using other terms that won't confuse readers into thinking Bitcoin's
double spend protection doesn't work.
- Add warning about backing up more than your seed when multisig or
complex contracts are in use.
- Add a todo to fix "millibits" situation, which might involve image
changes.
- Note that the first commitment transaction (the refund) needs to be
signed before the funding transaction in LN channels.
- Pluralize "bitcoin" as necessary (somehow missed this before).
- Drop mention of tumblebit and teechan, which nobody is working on
AFAIK.
- s/bitcoin/Bitcoin/ when appropriate
- Proof of work is only part of security
- Mining is separate from verificatino
- Kill BIP38 encrypted private keys section (mention seeds instead)
