Karmashares seems interesting, however, how would you prove that you own these shares to sell generates shares (or sell them all if you want in the future)?
For example, if I was the owner of
THESE shares then where is the proof? A screen shot of you wallet or something like that? Because that could easily be photo-shopped/faked.
The shares are attached to the wallet, which will be viewable to all in the Share Explorer. This is powered by the blockchain.
You can prove you own the wallet address (by signing a message) so would be able to prove that you have the shares.
And while it can be proven that the coins have been transferred for shares what's to stop you closing the shares scheme down and keeping all the coins??
