Willowʼ25

This crate provides concrete parameter choices for the Willow family of specifications, currently:

• Willow Data Model
• Meadowcap

With choices for the Willow Sideloading Protocol and Willow General Purpose Sync Protocol to follow.

We want it to be easy (and safe!) to start using the various Willow crates, and for there to be an ecosystem of interoperable Willow instances. We'd also like to release this in the year 2025 C.E. Hence, Willowʼ25!

Willowʼ25 uses:

• ed25519 signing and verification provided by ed25519_dalek
• (Temporarily) BLAKE3 cryptographic hashing provided by blake3. This will eventually be replaced by WILLAM3 cryptographic hashing to allow partial payload verification.

These choices have been chosen to balance performance and cryptographic security. They have not yet been audited in combination with Willow protocols.
