Luke Parker	469ce9106b	Implement a binary search for BatchVerifier blame ... Adds helper functions to verify and, on failure, blame, which move an unwrap from callers into multiexp where it's guaranteed to be safe and easily verified to be proper. Closes https://github.com/serai-dex/serai/issues/10.	2022-05-27 02:01:01 -04:00
Luke Parker	c90e957e6a	Add a batch verifier to multiexp, along with constant time variants ... Saves ~8% during FROST key gen, even with dropping a vartime for a constant time (as needed to be secure), as the new batch verifier is used where batch verification previously wasn't. The new multiexp API itself also offered a very slight performance boost, which may solely be a measurement error. Handles most of https://github.com/serai-dex/serai/issues/10. The blame function isn't binary searched nor randomly sorted yet.	2022-05-27 00:52:44 -04:00
