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.\n\nIn order to use the bellman-based zk-SNARKS on Substrate, following features are added to this library.\n- `no_std` compatible \n- some attributes (like `Encode`, `Decode`, etc...)for binary serialization and deserialization. (These codec is implemented as a [parity-codec](https://github.com/paritytech/parity-codec).)\n- `Rng` fixes to be compatible with wasm.\n\n\n## Security Warnings\n\nThese libraries are currently under development and have not been fully-reviewed.\n\n## License\n\nAll code in this workspace is licensed under either of\n\n * Apache License, Version 2.0, ([LICENSE-APACHE](LICENSE-APACHE) or http://www.apache.org/licenses/LICENSE-2.0)\n * MIT license ([LICENSE-MIT](LICENSE-MIT) or http://opensource.org/licenses/MIT)\n\nat your option.\n\n### Contribution\n\nUnless you explicitly state otherwise, any contribution intentionally\nsubmitted for inclusion in the work by you, as defined in the Apache-2.0\nlicense, shall be dual licensed as above, without any additional terms or\nconditions.\n","funding_links":[],"categories":["Ecosystem Tools","Rust"],"sub_categories":[],"project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2FLayerXcom%2Fbellman-substrate","html_url":"https://awesome.ecosyste.ms/projects/github.com%2FLayerXcom%2Fbellman-substrate","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2FLayerXcom%2Fbellman-substrate/lists"}
