Uhh, I as a casual browser of HN was quite confused when I clicked on this, as your github repo has no explanation of what Chain Core is, or what it does.
Perhaps consider saying something like "Chain Core is a blockchain based system for private B2B financial transactions, such as deposits, bonds, securities and currency exchanges." up front so other HN readers aren't forced to eventually wander to your website[1] to figure out what this chain thing is.
