Hello and happy new year to this mailing list!
Thank you Mark for the incredible work you've been doing on this.
I am following this very closely, because it is of primary importance
for Electrum.
I have written a Python-levelDB implementation of this UTXO hashtree,
which is currently being test

Hi Jeremy, Let's give a preview of the application-oriented BIPs I
mentioned:
Stateless validation and mining involves prefixing transaction and
block messages with proofs of their UTxO state changes. These are the
"operational proofs" I describe in t

Wow there's a lot here to think about. I'm pretty sure I haven't grasped
the full implications yet.
I see it proposes to also introduce additional BIPs describing the use of
