Ye contributed to the matter-labs/zksync-os repository by engineering cryptographic and performance enhancements across several core components. Over four months, Ye implemented optimized elliptic curve operations, including a high-performance P256 secp256r1 path and BN254 endomorphism-based point multiplication, using Rust and low-level programming techniques. Ye introduced a modular U256 integer type and improved memory management by relocating data sections to RAM, reducing ROM dependencies and accelerating startup. The work involved custom type implementation, BigInt arithmetic, and CI/CD integration for benchmarking, resulting in more efficient cryptographic workflows, scalable architecture, and a foundation for future optimizations in embedded and cryptographic systems.

Aug 1, 2025In Aug 2025, delivered a memory-management enhancement for matter-labs/zksync-os that relocates .rodata and .data from ROM to RAM, removes ROM checks, and enables initialized statics. Updated linker script and Rust code to support the change, improving startup and runtime efficiency. Linked to commit ced1c9fbe92fe8af1e411e91aac4085a89e17deb (perf: copy .rodata to RAM (#206)). This work reduces ROM dependencies, accelerates boot, and lays groundwork for future memory optimizations.
