Development has moved to the [zksync-crypto](https://github.com/matter-labs/zksync-crypto) repository.\n\u003e Please use it instead.\n\n# bellman \"Community edition\"\n \nOriginally developed for ZCash, it has diverged now and focuses solely on the [PLONK](https://eprint.iacr.org/2019/953) proof system. Uses our \"community edition\" pairing for Ethereum's BN256 curve. \n\n## Features\n\nAllows one to design PLONK circuits with custom gates and lookup tables with junction with [franklin-crypto](https://github.com/matter-labs/franklin-crypto) gadget library. At the moment the lookup argument implies using the lookup over the first three state columns (usually refered as A/B/C) and allows to have simultaneously a gate and a lookup applied on the same row of the trace.\n\n## License\n\nLicensed 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### Code Examples:\n\n- [Edcon2019_material](https://github.com/matter-labs/Edcon2019_material)\n- [EDCON Workshop record (youtube): Intro to bellman: Practical zkSNARKs constructing for Ethereum](https://www.youtube.com/watch?v=tUY0YGTpehg\u0026t=74s)\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","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fmatter-labs%2Fbellman","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fmatter-labs%2Fbellman","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fmatter-labs%2Fbellman/lists"}
