* Standardize the DLEq serialization function naming They mismatched from the rest of the project. This commit is technically incomplete as it doesn't update the dkg crate. * Rewrite DKG encryption to enable per-message decryption without side effects This isn't technically true as I already know a break in this which I'll correct for shortly. Does update documentation to explain the new scheme. Required for blame. * Add a verifiable system for blame during the FROST DKG Previously, if sent an invalid key share, the participant would realize that and could accuse the sender. Without further evidence, either the accuser or the accused could be guilty. Now, the accuser has a proof the accused is in the wrong. Reworks KeyMachine to return BlameMachine. This explicitly acknowledges how locally complete keys still need group acknowledgement before the protocol can be complete and provides a way for others to verify blame, even after a locally successful run. If any blame is cast, the protocol is no longer considered complete-able (instead aborting). Further accusations of blame can still be handled however. Updates documentation on network behavior. Also starts to remove "OnDrop". We now use Zeroizing for anything which should be zeroized on drop. This is a lot more piece-meal and reduces clones. * Tweak Zeroizing and Debug impls Expands Zeroizing to be more comprehensive. Also updates Zeroizing<CachedPreprocess([u8; 32])> to CachedPreprocess(Zeroizing<[u8; 32]>) so zeroizing is the first thing done and last step before exposing the copy-able [u8; 32]. Removes private keys from Debug. * Fix a bug where adversaries could claim to be using another user's encryption keys to learn their messages Mentioned a few commits ago, now fixed. This wouldn't have affected Serai, which aborts on failure, nor any DKG currently supported. It's just about ensuring the DKG encryption is robust and proper. * Finish moving dleq from ser/deser to write/read * Add tests for dkg blame * Add a FROST test for invalid signature shares * Batch verify encrypted messages' ephemeral keys' PoP |

monero-serai
A modern Monero transaction library intended for usage in wallets. It prides itself on accuracy, correctness, and removing common pit falls developers may face.
monero-serai contains safety features, such as first-class acknowledgement of the burning bug, yet also a high level API around creating transactions. monero-serai also offers a FROST-based multisig, which is orders of magnitude more performant than Monero's.
monero-serai was written for Serai, a decentralized exchange aiming to support Monero. Despite this, monero-serai is intended to be a widely usable library, accurate to Monero. monero-serai guarantees the functionality needed for Serai, yet will not deprive functionality from other users, and may potentially leave Serai's umbrella at some point.
Various legacy transaction formats are not currently implemented, yet monero-serai is still increasing its support for various transaction types.
