🛡️ Protocol & Infrastructure Security Researcher
> Focus: Core Blockchain Infrastructure (L1/L2) | Consensus Logic | High-Severity DoS > Stack: Go (Golang) • Solidity • Rust
👨💻 About Me
I am a specialized security researcher bridging the gap between Smart Contract logic and Client-side infrastructure. While most auditors stop at the EVM boundary, I dive into the node implementation to find vulnerabilities that threaten the entire chain's liveness.
My competitive advantage lies in analyzing Go-based architectures (Optimism Stack, Geth) to identify concurrency bugs, resource exhaustion vectors, and p2p networking flaws.
🛠️ Technical Arsenal
| Domain | Languages | Tooling & Frameworks |
|---|---|---|
| Node Implementation | Go (Expert), Rust | Geth Source, P2P Simulators, Go Fuzzing |
| Smart Contracts | Solidity, Yul | Foundry, Echidna, Medusa, Halmos |
| Analysis Style | Manual Review | Invariant Testing, Formal Verification |
🧠 Research Methodology
I don't just look for standard vulnerabilities (Reentrancy, Overflow). I model the system architecture to find deeper flaws:
- Liveness & Availability: Can I turn the node off? Can I freeze the bridge?
- Consensus Integrity: Can I trick the client into accepting an invalid chain tip?
- Economic Logic: Can I bypass the accounting mechanism using dust attacks or rounding errors?
