dedicated workspace (#70) * change: Refactor structure into workspace * chore: Add empty readme * change: Transform repo into workspace * add: Create folding-verifier-solidity crate * add: Include askama.toml for `sol` extension escaper * add: Jordi's old Groth16 verifier .sol template and adapt it * tmp: create simple template struct to test * Update FoldingSchemes trait, fit Nova+CycleFold - update lib.rs's `FoldingScheme` trait interface - fit Nova+CycleFold into the `FoldingScheme` trait - refactor `src/nova/*` * chore: add serialization assets for testing Now we include an `assets` folder with a serialized proof & vk for tests * Add `examples` dir, with Nova's `FoldingScheme` example * polishing * expose poseidon_test_config outside tests * change: Refactor structure into workspace * chore: Add empty readme * change: Transform repo into workspace * add: Create folding-verifier-solidity crate * add: Include askama.toml for `sol` extension escaper * add: Jordi's old Groth16 verifier .sol template and adapt it * tmp: create simple template struct to test * feat: templating kzg working * chore: add emv and revm * feat: start evm file * chore: add ark-poly-commit * chore: move `commitment` to `folding-schemes` * chore: update `.gitignore` to ignore generated contracts * chore: update template with bn254 lib on it (avoids import), update for loop to account for whitespaces * refactor: update template with no lib * feat: add evm deploy code, compile and create kzg verifier * chore: update `Cargo.toml` to have `folding-schemes` available with verifiers * feat: start kzg prove and verify with sol * chore: compute crs from kzg prover * feat: evm kzg verification passing * tmp * change: Swap order of G2 coordinates within the template * Update way to serialize proof with correct order * chore: update `Cargo.toml` * chore: add revm * chore: add `save_solidity` * refactor: verifiers in dedicated mod * refactor: have dedicated `utils` module * chore: expose modules * chore: update verifier for kzg * chore: rename templates * fix: look for binary using also name of contract * refactor: generate groth16 proof for sha256 pre-image, generate groth16 template with verifying key * chore: template renaming * fix: switch circuit for circuit that simply adds * feat: generates test data on the fly * feat: update to latest groth16 verifier * refactor: rename folder, update `.gitignore` * chore: update `Cargo.toml` * chore: update templates extension to indicate that they are templates * chore: rename templates, both files and structs * fix: template inheritance working * feat: template spdx and pragma statements * feat: decider verifier compiles, update test for kzg10 and groth16 templates * feat: parameterize which size of the crs should be stored on the contract * chore: add comment on how the groth16 and kzg10 proofs will be linked together * chore: cargo clippy run * chore: cargo clippy tests * chore: cargo fmt * refactor: remove unused lifetime parameter * chore: end merge * chore: move examples to `folding-schemes` workspace * get latest main changes * fix: temp fix clippy warnings, will remove lints once not used in tests only * fix: cargo clippy lint added on `code_size` * fix: update path to test circuit and add step for installing solc * chore: remove `save_solidity` steps * fix: the borrowed expression implements the required traits * chore: update `Cargo.toml` * chore: remove extra `[patch.crates-io]` * fix: update to patch at the workspace level and add comment explaining this * refactor: correct `staticcall` with valid input/output sizes and change return syntax for pairing * refactor: expose modules and remove `dead_code` calls * chore: update `README.md`, add additional comments on `kzg10` template and update `groth16` template comments * chore: be clearer on attributions on `kzg10` --------- Co-authored-by: CPerezz Co-authored-by: arnaucube --- .github/workflows/ci.yml | 6 +-
