Rongjian Lan

He focused on implementing low-level network components, such as the P2P network, cross-shard message routing, smart contract implementation, and client software optimization for validators and stakers. His engineering decisions determined the bandwidth, latency, and infrastructure requirements, which in turn shaped the validator profile and operating costs of ecosystem participants. He participated in the release cycle, network update testing, and monitoring tool development, thereby reducing risks during major updates. Additionally, he worked on hardware and software optimizations that enabled the project to demonstrate high TPS in test scenarios, enhancing ONE's appeal for scalability-focused projects with low fees.
