Why do you need the blockchain for this? Couldn't you just sell shares? Sorry, I'm on mobile and don't have the time to dig through the whitepaper. Will do that later.

If you sell the share, then the tokens will fall under equity regulations + will not be listed on Major exchanges, BUT the solution the team has found to this is great.
They will be buying the tokens back from the token holders anally which will boost the token price.
The best thing in the Kepler Technologies LLC is that they will not be distributing dividends. which means that all the company income will be used for Company development and for buying back the tokens.
From what I know, if they make their own blockchain they will use it to build the blockchain city! they will be helping other blockchain startups to acquire land in Georgia for free and help with the legislation and regulations!
