I am an active contributor to the Ethereum L2 ecosystem, focusing on the architectural integrity, prover stability, and security of ZK-proof systems. Recently, I completed a "contribution marathon" across Linea, ZKsync, and Scroll, addressing critical bottlenecks in tracer logic and system constants.
- Issue: Resolved the decoupling of reported line counts from actual trace height in arithmetic modules (Issue #1955).
- Solution: Refactored
computeLineCount()logic inMulOperation.javaandExpOperation.javato support dynamic row calculation based on instruction complexity. - Impact: Eliminated "silent errors" and
nullrow padding in.1ttrace files, ensuring stable proof generation and providing the foundation for the upcoming "small fields" update.
- Contribution: Optimized system parameters in the prover codebase (PR #1230).
- Action: Conducted a comprehensive refactoring of magic constants into named parameters to improve security auditability.
- Result: Enhanced code maintainability and transparency for the core proof generation pipeline.
- Analysis: Identified discrepancies in gas limit constants within the rollup infrastructure (Issue #407).
- Outcome: Initiated updates to the technical documentation regarding gas hardcoding, preventing dApp developers from encountering transaction estimation errors on the Scroll network.
- ZK-EVM: Trace expansion logic, Arithmetic circuits, Constraint validation.
- Languages: Java/Kotlin (ZkTracer), Rust (Prover logic), Solidity.
- Tools: Gradle, Geth/Besu internals, Corset/Zkasm, Hardhat.
- Deep Architectural Insight: Proven ability to trace and fix issues from high-level EVM opcodes down to low-level trace row generation.
- Security-First Approach: Focused on eliminating hardcoded constants and silent failure points that compromise prover reliability.

- Status: Open to collaborations on ZK-infrastructure and Ethereum L2 scaling.
