Subject: [Bitcoin-development] BIP draft - Auxiliary Header Format
Date: Sat, 8 Nov 2014 23:45:27 +0000	[thread overview]
Message-ID: <CAE-z3OW3=mBNC_p911y6HspF4r9g=sSPM2S-mmBTm+=hoxDprA@mail.gmail.com> (raw)

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 soft fork and it uses the last transaction in the block to store
the hash of the auxiliary header.

It makes use of the fact that the last transaction in the block has a much
less complex Merkle branch than the other transactions.
