Summary
🤩
Rockstar🎓
Top SchoolErik Zhang is a blockchain pioneer and CTO with 11 years of engineering leadership, best known as a founder and core developer of the NEO project and an author of the dBFT consensus mechanism. Based in Shanghai, he blends deep low-level blockchain and VM design with hands-on full‑stack development, having implemented VM Map opcodes, stack isolation, wallet indexing, RPC extensions, and GUI integrations. His work spans core protocol improvements (neo, neo-vm, neo-node) to user-facing features (neo-gui), showing a rare ability to move between consensus, VM internals, wallet mechanics, and UI flows. A certified information systems auditor with a background in computer security, he brings rigorous, auditable engineering practices to distributed systems. He co‑founded Onchain and continues to steer production blockchain platforms that balance performance, usability, and security. An interesting detail: beyond protocol design he has personally reshaped VM architecture and added higher-level UI wallet workflows, demonstrating both systems-level vision and product sensibility.

NEO Virtual Machine
Role in this project:
Back-end Developer
Back-end DeveloperContributions:2 releases, 86 reviews, 166 commits in 4 years 10 months
Contributions summary:Erik significantly enhanced the NEO Virtual Machine (VM) by introducing the `Map` data structure, along with associated opcodes to manage its functionality. This included implementing features such as creating, accessing, and modifying map entries, as well as modifying existing opcodes like `ARRAYSIZE` and `PICKITEM` to support the new data type. The user also worked on the stack isolation, which included moving the `EvaluationStack` and `AltStack` from `ExecutionEngine` to `ExecutionContext`. This work streamlined the VM's architecture.
