The definitions of purity and side effects are ambiguous. For instance, suppose we have a function that reads, but does modify, state that is reachable from its inputs. Is that...

The implementation of towered fields is difficult to relate to documented constructions

6

(This issue spans `algebra` and `curves`, but seems more pertinent here.) Consider the implementation of towers of field extensions, for example [here](https://github.com/arkworks-rs/curves/blob/master/bls12_381/src/fields) for BLS12-381. The usual way to describe such...

Projects that rely on BOSL exceptions should say that they do

This is important licensing information since it affects how those projects can be forked. * `zcash_script` depends on `orchard` via `zcash_primitives`: * https://github.com/ZcashFoundation/zcash_script/blob/c9fbc441efd78593ba6a9828be45baf2d6469757/Cargo.toml#L57-L58 * https://github.com/ZcashFoundation/zcash_script/issues/36 * `zcash_chain` depends on `orchard`...

Part of #447.

The additional restrictions that were placed on Ed25519 public keys before Canopy are not needed, provided that an implementation checkpoints on the Canopy activation block or later for the Zcash...
