A big thank you to you and your team, Jaromil! Dyne's review and input
on the cryptographic specifications have been very helpful in ensuring
that we do the best job that we can to create a pipeline for more
privacy-preserving and cutting edge cryptography.

The current 7-10 year national standards pipeline that we have to get
adoption on cryptography that starts out being 10-20 years old at the
start of that process is broken and needs to be fixed. That is one of
the core design goals for Data Integrity -- decentralize and speed up
innovation in cryptography through at least the DIF and W3C.

Yes, and this has been something we've been trying to communicate for
years -- so it's nice to see implementers, such as yourself, get it.

While canonicalization is more complex than not doing it (obviously),
by performing the transformation, we can get to more efficient and
flexible cryptographic systems, especially when it comes to privacy
preserving cryptography. Now that we have those cryptographic
baselines as global standards, we can continue to build on that
cryptographic primitive with BBS and some of the other cryptographic
circuit-based Zero-Knowledge mechanisms.

As some have seen through the summaries for the CCG Data Integrity
calls we have on Friday, we're excited by the prospect that we can
produce a solution that is more efficient than the current one that is
being presented for mDL and SD-JWT (presented two weeks ago in CCG by
Google's team), and that's because of the way Data Integrity is
layered to enable maximum efficiency when it comes to these exciting
new cryptographic primitives.

The end-result here is real world deployment of privacy-preserving
zero-knowledge cryptography without having to wait another 10-30 years
for it to work its way through the global and national standardization
bodies.
