Those particular BIPs are abandoned. BIP324 takes the place of BIP151,
but a lot of this section refers to authentication, which is not in
BIP324. Also, this section mentions implementation, but BIP324 has not
been deployed as of this writing.
- Describe BIP152 compact block relay
- Describe why we still need relay networks (what they do that BIP152
can't)
- Drop FALCON relay (never used, AFAIK)
- Minor updates to relay section
- Remove images: these are incorrect and (IMO) not very useful. The
first image is a legend. The second image contains multiple errors or
confusions, such as implying that a miner needs a full copy of the
block chain or that a wallet is a routing node. The third image is a
very busy depiction of a network showing that clients connect to
nodes, which I think is fine to just say in the text.
- Revise text to not reference images.
- Maintain distinction between nodes and peers by not using terms "full
node client" or "SPV node"
- Update the count of reachable nodes
- Remove some dead full node implementations
- We revise sentence about equality among peers to make it clear that
the peers are full nodes. Clients are not peers of a full node.
- Remove clause about "reciprocity" being the incentive for
participation. I think there are varied reasons for operating a full
node, ranging from wanting to validate your own transactions
(requiring only a pruning full node) to wanting to keep mining
decentralized (e.g. by relaying transactions).
- Drop line about non-Bitcoin-P2P protocols being "extended Bitcoin
network". I think that's an unnecessary categorization.
- New introduction to fees
- More detail about how the fee market works
- Adds RBF and CPFP fee bumping
- Adds transaction pinning
- Adds package relay
- Adds CPFP carve out
- Small edits to 'Adding fees'
- Tiny edits to fee sniping
- "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
