Jan Xie

Provided direct technical leadership in implementing the CKB protocol and its main components, ensuring the transition from specifications to production code. Responsible for the architecture and development of CKB client software, including the implementation of CKB-VM, transaction formats, consensus rule checking, and cell storage mechanisms. Under his supervision, the maintenance of repositories, integration of testing tools and automated builds was carried out, which allowed maintaining network stability during early releases. Coordinated work on protocol safe upgrades and hardforks/softforks, and prepared technical roadmaps and change descriptions for node operators. His decisions on implementing a modular virtual machine and state format influenced the compatibility of second layers and the possibility of migrating existing applications. Work in the field of optimizing client performance and ensuring compatibility with the developer tools ecosystem became key for attracting projects using CKB as a basic layer for storing and executing smart contracts.
