There was a problem hiding this comment.
Please check for typos throughout.
Also please say a bit more / give an example of the vanilla table format if we only look at the first row per round. (I think having an actual markdown table could be very helpful visually - maybe GPT can just make this.)
And then same example but explaining what happens in the leaf circuit with encoding.
GPT is pretty useful! It helped me correct typos and generate the prototype of the table |

Very nice tables! I think this will be very helpful.
One last question: is is_final actually 1 on the first 17 rows in the table?
From
is_final: is_final_block && round == NUM_ROUNDS && row_idx == 0,
I actually thought it was only going to be nonzero on row 250.
My understanding on is_final was inaccurate. Corrected the description. |

* fix: change all `1` to `1u64` to prevent unexpected overflow (#72) * [Fix] Panic when dealing with identity point (#71) * More ecdsa tests * Update mod.rs * Update tests.rs * Update ecdsa.rs * Update ecdsa.rs * Update ecdsa.rs * msm tests * Update mod.rs * Update msm_sum_infinity.rs * fix: ec_sub_strict was panicing when output is identity * affects the MSM functions: right now if the answer is identity, there will be a panic due to divide by 0 instead of just returning 0 * there could be a more optimal solution, but due to the traits for EccChip, we just generate a random point solely to avoid divide by 0 in the case of identity point * Fix/fb msm zero (#77) * fix: fixed_base scalar multiply for [-1]P * feat: use `multi_scalar_multiply` instead of `scalar_multiply` * to reduce code maintanence / redundancy * fix: add back scalar_multiply using any_point * feat: remove flag from variable base `scalar_multiply` * feat: add scalar multiply tests for secp256k1 * fix: variable scalar_multiply last select * Fix/msm tests output identity (#75) * fixed base msm tests for output infinity * fixed base msm tests for output infinity --------- Co-authored-by: yulliakot <[email protected]> * feat: add tests and update CI --------- Co-authored-by: yuliakot <[email protected]> Co-authored-by: yulliakot <[email protected]> --------- Co-authored-by: yulliakot <[email protected]> Co-authored-by: yuliakot <[email protected]> * fix: redundant check in `ec_sub_unequal` * Add SafeType (#26) * Add SafeType * Refactor & add testing * Add doc comment * Refactor SafeChip * Move gen_proof/check_proof to utils * Fix merge issues * feat(CI): switch to larger runner * fix(builder): handle empty ctx with only equality constraints * feat: add SafeAddress and SafeUint160 (#85) * feat: add SafeAddress and SafeUint160 * fix incorrect byte size * Release 0.3.0 (#86) * feat: upgrade overall `halo2-base` API to support future multi-threaded assignments using our basic gate * WIP: currently `gates::flex_gate` is updated and passes basic test * BUG: `GateInstructions::idx_to_indicator` was missing a constraint to 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!!! * update: working benches for `mul` and `inner_product` * feat: add `test_multithread_gates` * BUG: `get_last_bit` did not do an `assert_bit` check on the answer * this function was not used anywhere * fix: `builder::assign_*` was not handling cases where two gates overlap and there is a break point in that overlap * we need to copy a cell between columns to fix * feat: update `gates::range` to working tests and new API * 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. * fix: change `AssignedValue` type to `KeccakAssignedValue` for compatibility after halo2-base update * Initial version 0.3.0 of halo2-ecc (#12) * 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` * Fix: assert uses of size hint in release mode (#13) * remove `size_hint` in `inner_product_simple` * change other uses of `size_hint` to follow with `assert_eq!` instead of `debug_assert_eq!` * Fix: bit decomposition edge cases (#14) * 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 * Initial checkpoint for halo2-ecc v0.3.0 (#15) * 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]> * Fix: make `GateThreadBuilder` compatible with external usage (#16) * 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: under-constrained `idx_to_indicator` (#17) *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 * Fix: soundness error in `FpChip::assert_eq` due to typo (#18) * 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 * Remove redundant code and prevent race conditions (#19) * 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`. * 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) * Add documentation for halo2-base (#27) * 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]> * Smart Range Builder (#29) * 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 * fix: `div_mod_var` when `a_num_bits <= b_num_bits` (#31) * Feat: extend halo2 base test coverage (#35) * 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]> * fix(ecdsa): allow u1*G == u2*PK case (#36) NOTE: current ecdsa requires `r, s` to be given as proper CRT integers TODO: newtypes to guard this assumption * fix: `log2_ceil(0)` should return `0` (#37) * Guard `ScalarField` byte representations to always be little-endian (#38) fix: guard `ScalarField` to be little-endian * fix: get_last_bit two errors (#39) 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 * Add documentation for all debug_asserts (#40) feat: add documentation for all debug_asserts * fix: `FieldChip::divide` renamed `divide_unsafe` (#41) Add `divide` that checks denomintor is nonzero. Add documentation in cases where `divide_unsafe` is used. * Use new types to validate input assumptions (#43) * 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 * Better handling of EC point at infinity (#44) * 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 * feat: use strict ec ops more often (#45) * `msm` implementations now always use `ec_{add,sub}_unequal` in strict mode for safety * Add docs to `scalar_multiply` and a flag to specify when it's safe to turn off some strict assumptions * feat: add `parallelize_in` helper function (#46) Multi-threading of witness generation is tricky because one has to ensure the circuit column assignment order stays deterministic. To ensure good developer experience / avoiding pitfalls, we provide a new helper function for this. Co-authored-by: Jonathan Wang <[email protected]> * fix: minor code quality fixes (#47) * feat: `fixed_base::msm_par` handles identity point (#48) We still require fixed base points to be non-identity, but now handle the case when scalars may be zero or the final MSM value is identity point. * chore: add assert for query_cell_at_pos (#50) * feat: add Github CI running tests (#51) * fix: ignore code block for doctest (#52) * feat: add docs and assert with non-empty array checks (#53) * Release 0.3.0 ecdsa tests (#54) * More ecdsa tests * Update mod.rs * Update tests.rs * Update ecdsa.rs * Update ecdsa.rs * Update ecdsa.rs * chore: sync with release-0.3.0 and update CI Co-authored-by: yulliakot <[email protected]> Co-authored-by: yuliakot <[email protected]> * chore: fix CI cannot multi-thread tests involving lookups due to environment variables * fix: `prop_test_is_less_than_safe` (#58) This test doesn't run any prover so the input must satisfy range check assumption.

* fix: change all `1` to `1u64` to prevent unexpected overflow (#72) * [Fix] Panic when dealing with identity point (#71) * More ecdsa tests * Update mod.rs * Update tests.rs * Update ecdsa.rs * Update ecdsa.rs * Update ecdsa.rs * msm tests * Update mod.rs * Update msm_sum_infinity.rs * fix: ec_sub_strict was panicing when output is identity * affects the MSM functions: right now if the answer is identity, there will be a panic due to divide by 0 instead of just returning 0 * there could be a more optimal solution, but due to the traits for EccChip, we just generate a random point solely to avoid divide by 0 in the case of identity point * Fix/fb msm zero (#77) * fix: fixed_base scalar multiply for [-1]P * feat: use `multi_scalar_multiply` instead of `scalar_multiply` * to reduce code maintanence / redundancy * fix: add back scalar_multiply using any_point * feat: remove flag from variable base `scalar_multiply` * feat: add scalar multiply tests for secp256k1 * fix: variable scalar_multiply last select * Fix/msm tests output identity (#75) * fixed base msm tests for output infinity * fixed base msm tests for output infinity --------- Co-authored-by: yulliakot <[email protected]> * feat: add tests and update CI --------- Co-authored-by: yuliakot <[email protected]> Co-authored-by: yulliakot <[email protected]> --------- Co-authored-by: yulliakot <[email protected]> Co-authored-by: yuliakot <[email protected]> * fix: redundant check in `ec_sub_unequal` * Add SafeType (#26) * Add SafeType * Refactor & add testing * Add doc comment * Refactor SafeChip * Move gen_proof/check_proof to utils * Fix merge issues * feat(CI): switch to larger runner * fix(builder): handle empty ctx with only equality constraints * feat: add SafeAddress and SafeUint160 (#85) * feat: add SafeAddress and SafeUint160 * fix incorrect byte size * Release 0.3.0 (#86) * feat: upgrade overall `halo2-base` API to support future multi-threaded assignments using our basic gate * WIP: currently `gates::flex_gate` is updated and passes basic test * BUG: `GateInstructions::idx_to_indicator` was missing a constraint to 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!!! * update: working benches for `mul` and `inner_product` * feat: add `test_multithread_gates` * BUG: `get_last_bit` did not do an `assert_bit` check on the answer * this function was not used anywhere * fix: `builder::assign_*` was not handling cases where two gates overlap and there is a break point in that overlap * we need to copy a cell between columns to fix * feat: update `gates::range` to working tests and new API * 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. * fix: change `AssignedValue` type to `KeccakAssignedValue` for compatibility after halo2-base update * Initial version 0.3.0 of halo2-ecc (#12) * 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` * Fix: assert uses of size hint in release mode (#13) * remove `size_hint` in `inner_product_simple` * change other uses of `size_hint` to follow with `assert_eq!` instead of `debug_assert_eq!` * Fix: bit decomposition edge cases (#14) * 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 * Initial checkpoint for halo2-ecc v0.3.0 (#15) * 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]> * Fix: make `GateThreadBuilder` compatible with external usage (#16) * 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: under-constrained `idx_to_indicator` (#17) *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 * Fix: soundness error in `FpChip::assert_eq` due to typo (#18) * 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 * Remove redundant code and prevent race conditions (#19) * 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`. * 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) * Add documentation for halo2-base (#27) * 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]> * Smart Range Builder (#29) * 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 * fix: `div_mod_var` when `a_num_bits <= b_num_bits` (#31) * Feat: extend halo2 base test coverage (#35) * 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]> * fix(ecdsa): allow u1*G == u2*PK case (#36) NOTE: current ecdsa requires `r, s` to be given as proper CRT integers TODO: newtypes to guard this assumption * fix: `log2_ceil(0)` should return `0` (#37) * Guard `ScalarField` byte representations to always be little-endian (#38) fix: guard `ScalarField` to be little-endian * fix: get_last_bit two errors (#39) 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 * Add documentation for all debug_asserts (#40) feat: add documentation for all debug_asserts * fix: `FieldChip::divide` renamed `divide_unsafe` (#41) Add `divide` that checks denomintor is nonzero. Add documentation in cases where `divide_unsafe` is used. * Use new types to validate input assumptions (#43) * 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 * Better handling of EC point at infinity (#44) * 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 * feat: use strict ec ops more often (#45) * `msm` implementations now always use `ec_{add,sub}_unequal` in strict mode for safety * Add docs to `scalar_multiply` and a flag to specify when it's safe to turn off some strict assumptions * feat: add `parallelize_in` helper function (#46) Multi-threading of witness generation is tricky because one has to ensure the circuit column assignment order stays deterministic. To ensure good developer experience / avoiding pitfalls, we provide a new helper function for this.

* feat: upgrade overall `halo2-base` API to support future multi-threaded assignments using our basic gate * WIP: currently `gates::flex_gate` is updated and passes basic test * BUG: `GateInstructions::idx_to_indicator` was missing a constraint to 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!!! * update: working benches for `mul` and `inner_product` * feat: add `test_multithread_gates` * BUG: `get_last_bit` did not do an `assert_bit` check on the answer * this function was not used anywhere * fix: `builder::assign_*` was not handling cases where two gates overlap and there is a break point in that overlap * we need to copy a cell between columns to fix * feat: update `gates::range` to working tests and new API * 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. * fix: change `AssignedValue` type to `KeccakAssignedValue` for compatibility after halo2-base update * Initial version 0.3.0 of halo2-ecc (#12) * 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` * Fix: assert uses of size hint in release mode (#13) * remove `size_hint` in `inner_product_simple` * change other uses of `size_hint` to follow with `assert_eq!` instead of `debug_assert_eq!` * Fix: bit decomposition edge cases (#14) * 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 * Initial checkpoint for halo2-ecc v0.3.0 (#15) * 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]> * Fix: make `GateThreadBuilder` compatible with external usage (#16) * 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: under-constrained `idx_to_indicator` (#17) *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 * Fix: soundness error in `FpChip::assert_eq` due to typo (#18) * 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 * Remove redundant code and prevent race conditions (#19) * 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`. * 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) * Add documentation for halo2-base (#27) * 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]> * Smart Range Builder (#29) * 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 * fix: `div_mod_var` when `a_num_bits <= b_num_bits` (#31) * Feat: extend halo2 base test coverage (#35) * 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]> * fix(ecdsa): allow u1*G == u2*PK case (#36) NOTE: current ecdsa requires `r, s` to be given as proper CRT integers TODO: newtypes to guard this assumption * fix: `log2_ceil(0)` should return `0` (#37) * Guard `ScalarField` byte representations to always be little-endian (#38) fix: guard `ScalarField` to be little-endian * fix: get_last_bit two errors (#39) 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 * Add documentation for all debug_asserts (#40) feat: add documentation for all debug_asserts * fix: `FieldChip::divide` renamed `divide_unsafe` (#41) Add `divide` that checks denomintor is nonzero. Add documentation in cases where `divide_unsafe` is used. * Use new types to validate input assumptions (#43) * 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 * Better handling of EC point at infinity (#44) * 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 * feat: use strict ec ops more often (#45) * `msm` implementations now always use `ec_{add,sub}_unequal` in strict mode for safety * Add docs to `scalar_multiply` and a flag to specify when it's safe to turn off some strict assumptions * feat: add `parallelize_in` helper function (#46) Multi-threading of witness generation is tricky because one has to ensure the circuit column assignment order stays deterministic. To ensure good developer experience / avoiding pitfalls, we provide a new helper function for this. Co-authored-by: Jonathan Wang <[email protected]> * fix: minor code quality fixes (#47) * feat: `fixed_base::msm_par` handles identity point (#48) We still require fixed base points to be non-identity, but now handle the case when scalars may be zero or the final MSM value is identity point. * chore: add assert for query_cell_at_pos (#50) * feat: add Github CI running tests (#51) * fix: ignore code block for doctest (#52) * feat: add docs and assert with non-empty array checks (#53) * Release 0.3.0 ecdsa tests (#54) * More ecdsa tests * Update mod.rs * Update tests.rs * Update ecdsa.rs * Update ecdsa.rs * Update ecdsa.rs * chore: sync with release-0.3.0 and update CI Co-authored-by: yulliakot <[email protected]> Co-authored-by: yuliakot <[email protected]> * chore: fix CI cannot multi-thread tests involving lookups due to environment variables * fix: `prop_test_is_less_than_safe` (#58) This test doesn't run any prover so the input must satisfy range check assumption.

Bad for testing (multi-threaded issues). Now we use thread_local to have a global static for these config params that can be passed around. * chore: make utils folder and move some files * Fix halo2 base tests naming (#76) * feat: `BaseConfig` to switch between `FlexGateConfig` and `RangeConfig` - `RangeCircuitBuilder` now uses `BaseConfig` to auto-decide whether to create lookup table or not. - In the future this should be renamed `BaseCircuitBuilder` or just `CircuitBuilder`, but for backwards compatibility we leave the name for now. - `GateCircuitBuilder` no longer implements `Circuit` because we want to switch to having everyone just use `RangeCircuitBuilder`. - Tests won't compile now because we still need to refactor * feat: refactored halo2-base tests to use new test suite * feat: remove use of env var in halo2-ecc CI now can just run `cargo test` * feat: remove use of env var from zkevm-keccak * Add zkevm-keccak test to CI * chore: fix CI * chore: add lint to CI * chore: make Baseconfig fns public * fix(test): zkevm-keccak test should have `first_pass = SKIP_FIRST_PASS` Currently with `first_pass = true`, it skips the first pass, but when feature "halo2-axiom" is used, there is only one pass of `synthesize` so the whole thing gets skipped. Mea culpa! --------- Co-authored-by: Xinding Wei <[email protected]> * chore: make `bit_length` const function * feat: add debugging functions (#99) * feat: add debugging functions Functions only available for testing: * `ctx.debug_assert_false` for debug break point to search for other constrain failures in mock prover * `assigned_value.debug_prank(prank_value)` to prank witness values for negative tests * chore: code pretty * chore: remove cfg(test) for debug functions * feat(halo2-base): add `GateChip::pow_var` (#103) * Use halo2curves v0.4.0 and ff v0.13 (#107) * wip: change import to ff v0.13 * feat: remove `GateInstructions::get_field_element` halo2curves now has `bn256-table` which creates table of small field elements at compile time, so we should just use `F::from` always.

Update `halo2-ecc` (mostly the tests) with new circuit builder format. * fix: `LookupAnyManager` drop check `Arc` strong_count * feat: add back single column lookup with selector Special case: if only single advice column that you need to lookup, you can create a selector and enable lookup on that column. This means you add 1 selector column, instead of 1 advice column. Only using this for `RangeConfig` and not generalizing it for now. * feat: add example of dynamic lookup memory table * Bump versions to 0.4.0 * chore: re-enable poseidon and safe_types `Drop` for managers no longer panics because rust `should_panic` test cannot handle non-unwinding panics. * chore: remove `row_offset` from `assigned_advices` This PR was merged: privacy-scaling-explorations/halo2#192 * chore: move `range::circuit` to `gates::circuit` * nits: address review comments * feat: add `num_instance_columns` to `BaseCircuitParams` No longer a const generic * chore(CI): use larger runner * Use `raw_assign_{advice,fixed}` in keccak (#125) * chore: switch `halo2_proofs` branch to `main` * chore: use `raw_assign_{advice,fixed}` in keccak * [feat] PoseidonHasher supports multiple inputs in compact format (#127) * PoseidonHasher supports multiple inputs in compact format * Add comments * Remove unnecessary uses * [feat] Expose Keccack Raw Inputs in Bytes instead of Input RLCs (#124) * Expose Keccack raw inputs in bytes instead of input RLCs * Fix column name in comments * Add comments * Compress 8 bytes of inputs into a single witness * chore: add some comments * Rewrite gates * Fix comments & typos * Fix naming * Add comments * Selector improvement * Remove unused --------- Co-authored-by: Jonathan Wang <[email protected]> * Bump `zkevm-hashes` to v0.1.4 * chore: clippy fix * Generic vertical gate assignment (#129) * feat: make `single_phase::assign_with_constraints` generic Use const generic for max rotations accessed by the vertical gate.
