Changes to the Stylus Sprint Committee
Gustavo Gonzalez has taken a new role as the Director of Engineering at Taiko. After considering future availability, both sides felt it was best for Gustavo to step down from his responsibilities as a Stylus Sprint Committee member to fully focus on the new role. Entropy is very grateful for the time and hard work Gustavo put into evaluating applications and serving on the Stylus Sprint Committee. His expertise was invaluable in the selection of projects and providing feedback to teams as they progressed through milestones.
As we shared in the previous update & on the monthly GRC call, Daniel, the Stylus team lead at Open Zeppelin, was brought on as an additional reviewer to help speed up milestone evaluations. With Gustavo now stepping down from his role, the committee has now returned to its original structure of 7 members. The committee is still discussing if it is necessary to replace Gustavo immediately and if so, who would be the best potential replacement. For the time being, the compensation of the paid committee members will remain at 4000 ARB in order to reserve additional funds for a replacement.
