Could you please clarify for me who exactly holds the position of Chief Executive Officer, or CEO, for the company known as Voxels? I'm curious to learn about the leadership behind this particular cryptocurrency or blockchain-related venture, as their decisions and vision likely play a significant role in shaping the future of the organization. Additionally, I'm interested in understanding if there have been any changes in leadership recently, as such transitions can have notable impacts on a company's direction and performance.
