This helps identify where the various functionalities are used, or rather, not used. The `Ciphersuite` trait present in `patches/ciphersuite`, facilitating the entire FCMP++ tree, only requires the markers _and_ canonical point decoding. I've opened a PR to upstream such a trait into `group` (https://github.com/zkcrypto/group/pull/68). `WrappedGroup` is still justified for as long as `Group::generator` exists. Moving `::generator()` to its own trait, on an independent structure (upstream) would be massively appreciated. @tarcieri also wanted to update from `fn generator()` to `const GENERATOR`, which would encourage further discussion on https://github.com/zkcrypto/group/issues/32 and https://github.com/zkcrypto/group/issues/45, which have been stagnant. The `Id` trait is occasionally used yet really should be first off the chopping block. Finally, `WithPreferredHash` is only actually used around a third of the time, which more than justifies it being a separate trait. --- Updates `dalek_ff_group::Scalar` to directly re-export `curve25519_dalek::Scalar`, as without issue. `dalek_ff_group::RistrettoPoint` also could be replaced with an export of `curve25519_dalek::RistrettoPoint`, yet the coordinator relies on how we implemented `Hash` on it for the hell of it so it isn't worth it at this time. `dalek_ff_group::EdwardsPoint` can't be replaced for an re-export of `curve25519_dalek::SubgroupPoint` as it doesn't implement `zeroize`, `subtle` traits within a released, non-yanked version. Relevance to https://github.com/serai-dex/serai/issues/201 and https://github.com/dalek-cryptography/curve25519-dalek/issues/811#issuecomment-3247732746. Also updates the `Ristretto` ciphersuite to prefer `Blake2b-512` over `SHA2-512`. In order to maintain compliance with FROST's IETF standard, `modular-frost` defines its own ciphersuite for Ristretto which still uses `SHA2-512`.
Serai
Serai is a new DEX, built from the ground up, initially planning on listing Bitcoin, Ethereum, DAI, and Monero, offering a liquidity-pool-based trading experience. Funds are stored in an economically secured threshold-multisig wallet.
Layout
-
audits: Audits for various parts of Serai. -
spec: The specification of the Serai protocol, both internally and as networked. -
docs: User-facing documentation on the Serai protocol. -
common: Crates containing utilities common to a variety of areas under Serai, none neatly fitting under another category. -
crypto: A series of composable cryptographic libraries built around theff/groupAPIs, achieving a variety of tasks. These range from generic infrastructure, to our IETF-compliant FROST implementation, to a DLEq proof as needed for Bitcoin-Monero atomic swaps. -
networks: Various libraries intended for usage in Serai yet also by the wider community. This means they will always support the functionality Serai needs, yet won't disadvantage other use cases when possible. -
message-queue: An ordered message server so services can talk to each other, even when the other is offline. -
processor: A generic chain processor to process data for Serai and process events from Serai, executing transactions as expected and needed. -
coordinator: A service to manage processors and communicate over a P2P network with other validators. -
substrate: Substrate crates used to instantiate the Serai network. -
orchestration: Dockerfiles and scripts to deploy a Serai node/test environment. -
tests: Tests for various crates. Generally,crate/src/testsis used, orcrate/tests, yet any tests requiring crates' binaries are placed here.
Security
Serai hosts a bug bounty program via Immunefi. For in-scope critical vulnerabilities, we will reward whitehats with up to $30,000.
Anything not in-scope should still be submitted through Immunefi, with rewards issued at the discretion of the Immunefi program managers.
