Dear CFRG members,

We created an I-D for BLAKE3, a popular hash function that can be also used
as PRF, MAC, KDF, XOF::

https://datatracker.ietf.org/doc/draft-aumasson-blake3/

We would like to eventually turn it into an RFC, to formally standardize
BLAKE3 and make it eligible for integration in systems and organizations
that require this (like OpenSSL).

See also https://github.com/BLAKE3-team/BLAKE3/blob/master/README.md.

BLAKE3 is often used via the b3sum utility, for example from
https://crates.io/crates/b3sum
https://formulae.brew.sh/formula/b3sum

In the I-D we tried to describe BLAKE3's tree mode in the simplest way
possible, yet in a way sufficient to implement. The I-D does not include
source code, however, but instead refers to our C or Rust reference code at
https://github.com/BLAKE3-team/BLAKE3.

We would appreciate any informal feedback at this stage, and then we would
like to proceed with the formal review process as soon as possible. We will
follow the recommendations and instructions of the CFRG chairs, as we are
not familiar with the process.

Thank you for your attention to this new I-D submission.

JP, on behalf of the BLAKE3 team (Jack, Samuel, Zooko)
