Just reviewed the white paper for TKN. Looks like I should learn more. What is required is an easy way to register any kind of object, [or promise of some service] as a token that can be exchanged. I would also like to control who can buy or sell my token [say I don't want to serve a certain kind of business such as criminal organization].
This would enable me to sell/exchange an object in my house such as a gram of gold [share of a solar panel] without actually having to physically transfer the object to them at the PoS, like checks.
