February 2025: Focused on improving gas accuracy and cryptographic capabilities in NilFoundation/placeholder. Implemented a memory expansion subcomponent and integrated memory cost calculations across CALLDATACOPY, CODECOPY, RETURNDATACOPY, MCOPY, and LOG opcodes, enabling more precise ZK-EVM gas accounting. Refactored Keccak into a dynamic-block-friendly zkevm_keccak and aligned constructor/input types with updated tests. Refined carryless constraint logic across critical opcodes (addmod, div_mod, mulmod, sar, sdiv_smod, shl, shr) to improve correctness and maintainability. Added secp_k1 elliptic curve support, including base field components, EC operations, and ECDSA recovery with tests. These changes collectively enhance cost estimation accuracy, cryptographic capability, and codebase maintainability, reducing risk of regressions and enabling future optimizations.
