I was going to look into creating reference code for this.
The first BIP could be reasonably easy, since it just needs to check for
the presence of the 2 special transactions.
That would mean that it doesn't actually create version 3 blocks at all.
Ideally, I would make it easy for miners to min
I have added the network BIP too. It only has the aheaders message and the
extra field for getheaders.

The transaction definitions are still at:

I updated the BIP to cover only the specification of the transactions that
need to be added. I will create a network BIP tomorrow.

The aheaders message is required to make use of the data by SPV clients.
This could be in a separate BIP though. I wanted to show that the merkle
path to the aux-header transaction could be efficiently encoded, but a
reference to the other BIP would be sufficient.
For the other messages, the prob
Some initial comments...
Tying in the protocol changes is really confusing and the fact that
they seem to be required out the gates would seemingly make this much
harder to deploy. Is there a need to do that? Why can't the p2p part
be entirely separate from the comitted data?

I made some changes to the draft. The merkleblock now has the auxiliary
header information too.
There is a tradeoff between overhead and delayed transactions. Is 12.5%
transactions being delayed to the next block unacceptable? Would adding
padding transactions be an improvement?
Creating the "
I created a draft BIP detailing a way to add auxiliary headers to Bitcoin
in a bandwidth efficient way. The overhead per auxiliary header is only
around 104 bytes per header. This is much smaller than would be required
by embedding the hash of the header in the coinbase of the block.
It is a sof
