Thank you for all the work you've put into this. This is really
impressive to see, and I believe it's an important milestone not only
for the Go implementation, but for the whole GNUnet project as well.

I built and ran the service and it worked as expected!


I used Go 1.12 by the way, and didn't experience any issues.

Keep up the good work!
