This is only enforced by the Monero protocol due to a single check the mixRing isn't empty in get_pre_mlsag_hash. The value in ensuring there's a least one input is to ensure the safety of our rct_type functions, which determines the RctType based off structural analysis (specifically, input data if MlsagBorromean). rct_type was technically safe without this. A 0-input transaction would be mis-classified as RctFull/MlsagAggregate, which would then make the RctSignatures invalid for being RctFull (requiring exactly one input) yet not having inputs, meaning an invalid RctSignatures would be mis-classified yet still invalid. This just removes the risk of mis-classification in the first place, tightening the library's safety.
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. -
docs: 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. -
coins: Various coin 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. -
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. -
deploy: Scripts to deploy a Serai node/test environment.
