* skeleton of what is to be done * wip inner and outer sumchecks done * fix borrow checker issues * batched spartan prove done * Small improvements - Irregular shape yields error - Remove (W,E) clones - Use Math module for log2 - Generate tau using only 1 challenge - Remove some `clone()` - Comments * Fix evaluation points * Implement verifier * `CompressedSNARK` implementation * Tests fixed, failing * fix sumcheck, test passes * bound -> bind * remove todo * add test * Document BatchedRelaxedR1CSSNARKTrait and SuperNova CompressedSNARK. * working * - Remove debug code - Add Sumcheck::verify_batch - Uniformize batching of evals - Comments * Adress review comments - add itertools for multiunzip - avoid clones - avoid recomputing sizes for asserts * Fix asserts * batched ppsnark * Fix scaling * - Fix padding of poly_W - Optimized evaluation - use batch_diff_size - use multiunzip * rebase fixes * Only create taus once. * Avoid clone by not allocating PowPolynomial. * Riff on review. * refactor: Implement `.zip_eq()` for equal length iterator safety - Replaced `.zip()` with `.zip_eq()` across various files including `sumcheck.rs`, `mod.rs`, `batched_ppsnark.rs`, `batched.rs` and `snark.rs`, ensuring equal length enforcement in iterations and reducing out-of-bound errors. - Updated a multiunzip resulting in a double iteration in batched_ppsnark::prove. * add benchmark * fix witnes * fix: clean up iterators * feat: Introduce new utility macros in spartan module - Introduced a macro `zip_with` in `src/spartan/mod.rs` to simplify the process of zipping multiple iterators and applying a single parallel function. - Developed additional macros `nested_tuple` and `nested_idents` for detailed nested tuple patterns and identifiers respectively. - Implemented `zip_all` macro that acts as a fold-right zipping operator for all given expressions. * refactor: Refactor batched.rs to enhance code readability - Refactored `src/spartan/batched.rs` to use `zip_with()` macro improving the readability, simplification, and consistent usage in the code. - Inserted comments highlighting sections marked for review or possible future code simplification. * refactor: use zip_with! in batch_ppsnark - Updated `batched_ppsnark.rs` in the `src/spartan` directory with uses of zip_with macro * ignore local macro doctest * Use zip_with. * Implement and use zip_with_for_each. * Dubious double zip_with. * More zip_with. * Small fixes - `zip_with` for `batched_ppsnark` - Complete comment of `BatchedRelaxedR1CSSNARK` - Restore Abomonation bounds - Fix nits in `multilinear.rs` * refactor: more zip_with instances (microsoft#153) * refactor: more instances of zip_with * Supernova: Some rewrites (microsoft#154) * refactor: more zip_with * feat: Implement `FromIterator` for polynomial types - Enhanced `EqPolynomial`, `MultilinearPolynomial`, and `SparsePolynomial` with `FromIterator` implementation. * refactor: use instaces of Polynomial Fromiterator where possible * refactor: remove unused impls of FromIterator * refactor: address review comments * refactor: enhance scope visibility scope in Spartan and Supernova modules (microsoft#156) Absolute visibility modifiers tend to not inadvertently make things public when you move code, contrarily to (super). - Changed the visibility scope of several fields and methods within multiple substrates in the `ppsnark.rs` file to be within the `crate::spartan`. - Altered the module import path in the `circuit.rs` file from `super` to `crate::supernova`. - Modified the visibility of the `WitnessBoundSumcheck` in `batched_ppsnark.rs`, the visibility scope is now set to `crate::spartan`. - Scoped `batch_eval_prove` and `batch_eval_verify` functions within `crate::spartan` in `snark.rs`. * Avoid EqPolynomial when only for evals. * refactor: a few more instances of EqPolynomial::evals_from_points - in `multilinear.rs` and `ipa_pc.rs`, replaces the previous method `EqPolynomial::new(r.to_vec()).evals()` with a more efficient `EqPolynomial::evals_from_points(r)`. * doc: fix a few nits (microsoft#160) * refactor: rename powers -> squares - Renamed the `powers` method to `squares` in `PowPolynomial` struct within `src/spartan/polys/power.rs` and changed its visibility level. * fix: comment * fix: comment of batch * derive fixes * fix: compressed snark benchmark - Introduced `compressed-snark-supernova` within the `Cargo.toml` file. - fixed Rust * ci: Add trigger for PRs to batched_spartan (microsoft#165) * More zip with (microsoft#158) * Expand zip_with macros to accommodate more use. * Clippy. * Move Spartan macros to own module. * Only use zip_with_fn to implement convenience macros. * Use convenience zip_with macros more. * Remove for_each variants of zip_with macros. * Remove flat_map variants of zip_with. --------- Co-authored-by: porcuquine <porcuquine@users.noreply.github.com> * Introduce proper `MaskedEq` poly (microsoft#162) * Introduce proper `MaskedEq` poly * refactor: Refactor MaskedEq poly for improved testing and performance - Introduce lifetime parameters to `MaskedEqPolynomial` struct to improve memory management. - Modify the `MaskedEqPolynomial` creation process so it now requires a reference to an existing `EqPolynomial`. - Adapt corresponding tests to reflect the above changes. * Fix fmt & derive debug --------- Co-authored-by: François Garillot <francois@garillot.net> * Restore zip_with_for_each. (microsoft#166) Co-authored-by: porcuquine <porcuquine@users.noreply.github.com> * fix benchmark (microsoft#168) * Sumcheck update (microsoft#163) * Include number of instances in transcript * Clarify Sumcheck and verifier * Fix clippy * Streamline macro syntax (microsoft#169) * refactor: Refactor Spartan code for streamlined use of `zip_with_fn` Details: - Simplified the implementation of `BatchedRelaxedR1CSSNARKTrait` by replacing usage of `zip_with_iter` and related macros with `zip_with_fn`. - Eliminated `zip_with_iter`, `zip_with_par_iter`, `zip_with_into_iter`, and `zip_with_into_par_iter` macros from the codebase, reducing repetition and enhancing code organization. * refactor: Refactor zip functions - Replaced the `zip_with_fn!` function with the `zip_with!` function in various files, - Refactored `zip_with` and `zip_with_for_each` macros in `src/spartan/macros.rs` for improved handling of iterator projection specification. - Consolidated `zip_all_with_fn` macro's functionality into `zip_all` and eliminated unused macros. * fix: remove brackets * Small fixes (microsoft#170) * refactor: removed needless copies of `R1CSShape` - Modified the `primary_r1cs_shapes` function in `supernova/mod.rs` to return a vector of references, improving memory efficiency. - Use those `primary_r1cs_shapes` in the `setup` and `prove` methods of `CompressedSNARK`. - Altered the `BatchedRelaxedR1CSSNARKTrait` trait functions in `traits/snark.rs` to accept vector of references instead of reference, * refactor: Refactor polynomial size assertion checks in sumcheck.rs - Refactors the length assertion checks in the `prove_quad_batch` and `prove_cubic_with_additive_term_batch` methods in `src/spartan/sumcheck.rs`. - Simplified the code by replacing multiple `assert_eq` calls with a loop. * refactor: Remove "nested_tuple" macro from spartan macros - Removed the "nested_tuple" macro from the "src/spartan/macros.rs" file. * refactor: pedantic calls in tests --------- Co-authored-by: Matej Penciak <matej.penciak@gmail.com> Co-authored-by: Adrian Hamelink <adrian@hamelink.com> Co-authored-by: porcuquine <porcuquine@users.noreply.github.com> Co-authored-by: Hanting Zhang <hantingz@usc.edu> Co-authored-by: Samuel Burnham <45365069+samuelburnham@users.noreply.github.com> Co-authored-by: porcuquine <1746729+porcuquine@users.noreply.github.com> Co-authored-by: Adrian Hamelink <adrian.hamelink@gmail.com> Co-authored-by: Matej Penciak <96667244+mpenciak@users.noreply.github.com>
