Hi all,
I did a write up with a proof of concept of the idea of sharing
block templates with peers, particularly in order to improve compact
block relay when miners and nodes have differing mempool policies. It's
at:
https://delvingbitcoin.org/t/sharing-block-templates/1906
I've now also written up a draft BIP specifying the p2p messages that
uses, which can be found here:
https://github.com/ajtowns/bips/blob/202508-sendtemplate/bip-ajtowns-sendtemplate.md
Review welcome! If you prefer to make comments via a github review
rather than here or on delving, I've opened a PR on my own repo at
https://github.com/ajtowns/bips/pull/7 which you could use.
Cheers,
aj
