I find it interesting and commendable that someone's starting their own blockchain project, going their own way in a sea of small scale forks and large scale, super business-y looking endeavours.
What makes me cautious is the bit about "open source later" for a blockchain project. The open source bit also doesn't show up on the roadmap, it's just mentioned here, in this thread, a bit like an afterthought. I'm giving you credit for providing a Linux client nonetheless, however. For closed source projects that's not always a given, unfortunately.
The closed source nature of the client also makes me extra cautious security wise, despite virustotal.
