Merge pull request #228 from zcash/pasta_curves-crate 
Migrate to the pasta_curves crate

Jack Grigg a130edaade Remove metrics crate and inline modelling 
It is causing problems in (some) downstream crates, and we won't want
these annotations in the codebase anyway if a downstream crate is
collecting metrics. We'll be replacing this with the cost model binary
in https://github.com/zcash/halo2/pull/225 shortly.

Jack Grigg 62e50ae6bd Fix Group::random implementation for Pallas and Vesta 
Also removes the broken CurveAffine::from_bytes_wide and unused
CurveAffine::to_bytes_wide methods.

Jack Grigg 0a4db20d82 impl group::cofactor::CofactorGroup for Pallas and Vesta 
Prime-order groups can be treated as a group with a cofactor of 1,
allowing them to be used in cofactor-aware protocols like RedDSA.

 2021-02-25 18:17:50 +00:00
Jack Grigg bd17c726ac Add a Selector type 
This currently just wraps a `Column<Fixed>`, but enables us to start
writing circuits that can later have their selector usage optimised.

Merge pull request #209 from zcash/ecc-gadget-fixedpoints 
Store `Loaded` chip state in chip
 2021-02-26 04:24:28 +13:00
therealyingtong 4f17322c2d Allow Chip::load to return state that the Layouter will hold 
This enables chips that e.g. want to load multiple lookup tables into
the same columns to store state about where each table was layed out.
