Who are 'Arkade'? I think I have a reasonable understanding of the tech (vUTXOs, 'rounds', ASPs), but I curious about the community around it. Is Arkade a community of FOSS people, or a commercial profit-making entity? I couldn't find any of that info on the wallet I'm really excited to use Ark(ade), and also to find out more about who is driving this and how this can drive more free and open source software
