assignments using our basic gate * WIP: currently `gates::flex_gate` is updated and passes basic test
check that the indicator witness was equal to 1 when non-zero. * Previously the constraint ensured that `ind[i] = 0` when `idx != i` however `ind[idx]` could be anything!!!
* this function was not used anywhere
and there is a break point in that overlap * we need to copy a cell between columns to fix
* In keygen mode, the `CircuitBuilder` will clone the `ThreadBuilder` instead of `take`ing it because the same circuit is used for both vk gen and pk gen. This could lead to more memory usage for pk gen.
compatibility after halo2-base update
* add multi-thread witness assignment support for `variable_base_msm` and `fixed_base_msm` * batch size 100 MSM witness generation went from 500ms -> 100ms * Sync with updates in `halo2_proofs_axiom` * `assign_advice` not longer returns `Result` so no more `unwrap`
* remove `size_hint` in `inner_product_simple` * change other uses of `size_hint` to follow with `assert_eq!` instead of `debug_assert_eq!`
* fix: change `debug_assert` in `decompose_u64_digits_limbs` to restrict `bit_len < 64` and `decompose_biguint` to `64 <= bit_len < 128` * add more comprehensive tests for above two functions
* chore: clippy --fix * Feat/add readme (#4) * feat: add README * feat: re-enable `secp256k1` module with updated tests * chore: fix result println * chore: update Cargo halo2_proofs_axiom to axiom/dev branch * compatibility update with `halo2_proofs_axiom` Co-authored-by: Matthias Seitz <[email protected]>
* chore: expose gate_builder.unknown
* feat: `GateThreadBuilder::assign_all` takes assigned_{advices,constants}
as input instead of new hashmap, in case we want to constrain equalities
for cells not belonging to this builder
* chore: update halo2-pse tag
* fix: `GateThreadBuilder::assign_all` now returns `HashMap`s of
assigned cells for external equality constraints (e.g., instance cells,
`AssignedCells` from chips not using halo2-lib).
* fix: `assign_all` was not assigning constants as desired: it was
assigning a new constant per context. This leads to confusion and
possible undesired consequences down the line.
*fix(BUG): `GateChip::idx_to_indicator` still had soundness bug where at index `idx` the value could be 0 or 1 (instead of only 1) * feat: add some function documentation * test(idx_to_indicator): add comprehensive tests * both positive and negative tests
* chore: update halo2-ecc version to 0.3.0 * fix(BUG): `FpChip::assert_equal` had `a` instead of `b` typo * feat: add tests for `FpChip::assert_eq` * positive and negative tests
* feat: move `GateCircuitBuilder::synthesize` to `sub_synthesize` function which also returns the assigned advices. * reduces code duplication between `GateCircuitBuilder::synthesize` and `RangeCircuitBuilder::synthesize` and also makes it easier to assign public instances elsewhere (e.g., snark-verifier) * feat: remove `Mutex` to prevent non-deterministism * In variable and fixed base `msm_par` functions, remove use of `Mutex<GateThreadBuilder>` because even the `Mutex` is not thread- safe in the sense that: if you let `Mutex` decide order that `GateThreadBuilder` is unlocked, you may still add Contexts to the builder in a non-deterministic order. * fix: `fixed_base::msm_par` loading new zeros * In `msm_par` each parallelized context was loading a new zero via `ctx.load_zero()` * This led to using more cells than the non-parallelized version * In `fixed_base_msm_in`, the if statement depending on `rayon::current_number_threads` leads to inconsistent proving keys between different machines. This has been removed and now uses a fixed number `25`.
* Allow `assign_all` also if `witness_gen_only = true`
* adds draft documentation for range.rs * draft docs for lib.rs, utiils.rs, builder.rs * fix: add suggested doc edits for range.rs * docs: add draft documentation for flex_gate.rs * fix: range.rs doc capitalization error * fix: suggested edits for utils.rs docs * fix: resolve comments for range.rs docs * fix: resolve comments on flex_gate.rs docs * fix: resolve comments for lib.rs, util.rs docs * fix: resolve comments for builder.rs docs * chore: use `info!` instead of `println` for params * Allow `assign_all` also if `witness_gen_only = true` * Fix: `inner_product_left_last` size hint (#25) * docs: minor fixes --------- Co-authored-by: PatStiles <[email protected]>
* feat: smart `RangeCircuitBuilder`
Allow `RangeCircuitBuilder` to not create lookup table if it detects
that there's nothing to look up.
* feat: add `RangeWithInstanceCircuitBuilder`
* Moved from `snark-verifier-sdk`
* Also made this circuit builder smart so it doesn't load lookup table
if not necessary
* In particular this can also be used as a
`GateWithInstanceCircuitBuilder`
* chore: derive Eq for CircuitBuilderStage
* fix: RangeConfig should not unwrap LOOKUP_BITS
* feat: add flex_gate_test.rs and pos add() test * feat: add pos sub() test * feat: add pos neg() test * feat: add pos mul() test * feat: add pos mul_add() test * feat: add pos mul_not() test * feat: add pos assert_bit * feat: add pos div_unsafe() test * feat: add pos assert_is_const test * feat: add pos inner_product() test * feat: add pos inner_product_left_last() test * feat: add pos inner_product_with_sums test * feat: add pos sum_products_with_coeff_and_var test * feat: add pos and() test * feat: add pos not() test * feat: add pos select() test * feat: add pos or_and() test * feat: add pos bits_to_indicator() test * feat: add pos idx_to_indicator() test * feat: add pos select_by_indicator() test * feat: add pos select_from_idx() test * feat: add pos is_zero() test * feat: add pos is_equal() test * feat: add pos num_to_bits() test * feat: add pos lagrange_eval() test * feat: add pos get_field_element() test * feat: add pos range_check() tests * feat: add pos check_less_than() test * feat: add pos check_less_than_safe() test * feat: add pos check_big_less_than_safe() test * feat: add pos is_less_than() test * feat: add pos is_less_than_safe() test * feat: add pos is_big_less_than_safe() test * feat: add pos div_mod() test * feat: add pos get_last_bit() test * feat: add pos div_mod_var() test * fix: pass slices into test functions not arrays * feat: Add pos property tests for flex_gate * feat: Add positive property tests for flex_gate * feat: add pos property tests for range_check.rs * feat: add neg pranking test for idx_to_indicator * fix: change div_mod_var test values * feat(refactor): refactor property tests * fix: fix neg test, assert_const, assert_bit * fix: failing prop tests * feat: expand negative testing is_less_than_failing * fix: Circuit overflow errors on neg tests * fix: prop_test_mul_not * fix: everything but get_last_bit & lagrange * fix: clippy * fix: set LOOKUP_BITS in range tests, make range check neg test more robust * fix: neg_prop_tests cannot prank inputs Inputs have many copy constraints; pranking initial input will cause all copy constraints to fail * fix: test_is_big_less_than_safe, 240 bits max * Didn't want to change current `is_less_than` implementation, which in order to optimize lookups for smaller bits, only works when inputs have at most `(F::CAPACITY // lookup_bits - 1) * lookup_bits` bits * fix: inline doc for lagrange_and_eval * Remove proptest for lagrange_and_eval and leave as todo * tests: add readme about serial execution --------- Co-authored-by: Jonathan Wang <[email protected]>
NOTE: current ecdsa requires `r, s` to be given as proper CRT integers TODO: newtypes to guard this assumption
2 embarassing errors: * Witness gen for last bit was wrong (used xor instead of &) * `ctx.get` was called after `range_check` so it was getting the wrong cell
feat: add documentation for all debug_asserts
Add `divide` that checks denomintor is nonzero. Add documentation in cases where `divide_unsafe` is used.
* feat: add new types `ProperUint` and `ProperCrtUint` To guard around assumptions about big integer representations * fix: remove unused `FixedAssignedCRTInteger` * feat: use new types for bigint and field chips New types now guard for different assumptions on non-native bigint arithmetic. Distinguish between: - Overflow CRT integers - Proper BigUint with native part derived from limbs - Field elements where inequality < modulus is checked Also add type to help guard for inequality check in ec_add_unequal_strict Rust traits did not play so nicely with references, so I had to switch many functions to move inputs instead of borrow by reference. However to avoid writing `clone` everywhere, we allow conversion `From` reference to the new type via cloning. * feat: use `ProperUint` for `big_less_than` * feat(ecc): add fns for assign private witness points that constrain point to lie on curve * fix: unnecessary lifetimes * chore: remove clones
* feat: allow `msm_par` to return identity point * feat: handle point at infinity `multi_scalar_multiply` and `multi_exp_par` now handle point at infinity completely Add docs for `ec_add_unequal, ec_sub_unequal, ec_double_and_add_unequal` to specify point at infinity leads to undefined behavior
Because the thread will default to phase 0.
* feat: add `clear` function to circuit builder and managers * feat: add `BaseConfig::initialize` * fix: break points for multiphase * fix: clear should not change phase * chore: remove dbg
Backend implementation of `constrain_equal` depends on the order in which you add equality constraints, so it is not thread-safe...
* chore: fix comments * feat(base): add `GateInstructions::inner_product_left` function
* WIP * chore: make `KeccakAssignedRow` fields public * Refactor Keccak coprocessor circuit * Optimize Keccak circuit MAX_DEGREE * Fix comments * Fix bug & typos * Add testing & refactor folder structure * Debugging * Fix bugs * Fix typo & bug * feat(test): real prover tests use dummy input for keygen * chore: make `LoadedKeccakF` public * Also made `encoded_inputs_from_keccak_fs` public * Both are useful for external use to make lookup tables in app circuits * fix(keccak_leaf): review comments and optimization * chore: use `gate` when `range` not necessary * Move calculate base ciruit params out & Fix naming/comments * Make Field-related parameter functions const * feat: change `is_final` to `SafeBool` * nit * Fix typo --------- Co-authored-by: Jonathan Wang <[email protected]>
* Add keccak coprocessor encoding for VarLenBytesVec/FixLenBytesVec * Fix naming/nits * Fix nit
Fix fmt
* chore(keccak_leaf): make `generate_circuit_final_outputs` public * chore: add misc utility functions
Currently only used for testing
chore: cleanup code
* Keccak docs * Fix typos * Add examples * Fix comments/docs
