This library supports for using zk-SNARKs on substrate and is implemented as an extension of librustzcash.
Primary purpose of this library is to be used with zero-chain. However, it is designed to be as flexible as possible and might be suited well for any other projects to use zk-SNARKs on Substrate.
In order to use the bellman-based zk-SNARKS on Substrate, following features are added to this library.
no_stdcompatible- some attributes (like
Encode,Decode, etc...)for binary serialization and deserialization. (These codec is implemented as a parity-codec.) Rngfixes to be compatible with wasm.
These libraries are currently under development and have not been fully-reviewed.
