* update readme * fix brevis-network#88 - Field Arithmetic Bug in SepticExtension SubAssign Implementation * fix #144 - Silent truncation in verify() causes incomplete proof verification * fix #142 - First chunk having cpu chip is incorrectly checked in convert circuit * fix #124,148,186,215 - Remainder is not range checked correctly in reduceWithMaxBits for koalabear field adjusts the hint for koalabear (2^31 - 2^24 + 1) by constraining the lower 24 bits to 0 when the upper 7 bits are all set, as well as adjusting the corresponding range checks and other constants * fix brevis-network#79 - Scalar multiplication reduces by 2^n instead of the group order r * fix #126 - Malicious prover will generate invalid proofs due to underconstrained REM/REMU operations when divisor is 0 * fix #197 - is_real never checked for boolean inside syscall chip * fix #133,137 - two completeness checks issue * fix #199,200 - Quotient domain is completely controlled by prover * fix #204 - Chip ordering is used to fetch all chips instead of preprocessed ones * fix #206 - No check that the lookup multiplicities do not overflow * fix #137 - completeness checks must be added to every circuit that needs to guarantee the VM execution trace is complete (#844) * fix #219 - op_a_0 is not constrained inside MemoryReadWriteChip * fix #226 - Polynomial evaluations are never observed by recursive verifier * fix #228 - ro[config.log_blowup] is not checked to be zero in recursive verifier * fix #230 - Recursive verifier does not check for overflow of the lookup multiplicities * fix #233 - Recursive verifier does not validate chip used for preprocessed traces * fix brevis-network#69 - Word range check uses unconstrained upper_all_one local variable when field prime is Mersenne31 * fix #108 - Inconsistent Multiplicity Increment in read_ghost_addr * fix brevis-network#78 - wrong sign handling when x == 0 produces non-canonical / out-of-range x = p * fix brevis-network#75 - Missing offset check will cause integer overflow violating ELF specification * fix brevis-network#62 - read_write chip does not enforce constraints on opcode selectors * fix #128 - Malicious verifier will recover private witness values breaking zero-knowledge property * unfix #200 * disable m31 and add a comment explaining why * #124 - fix comment description * #226: update Cargo.lock * #144 - additional input length mismatches * add conditional * modify gnark tool * vm/src/chips/precompiles/edwards/ed_decompress.rs (brevis-network#78) * fix format * fix lint * Add onchain verifier constraints (brevis-network#76) * Add vm_ccs serde * Add template_vk commit constant * Tentative onchain constraint completion * chore: code cleanup * add gnark verify test * fix: save groth16_witness.json --------- Co-authored-by: liuxiaobleach <[email protected]> * Update gnark docker image version * Update vk_map bins * Update maximal_only shape_config * Update (vm_ccs, vm_pk, vm_vk) url * chore: code fmt --------- Co-authored-by: Alan <[email protected]> Co-authored-by: kaiwei-0 <[email protected]> Co-authored-by: liuxiao <[email protected]> Co-authored-by: benhuang2025 <[email protected]> Co-authored-by: eason <[email protected]>
