The story so far: you now have a digital universe (a network-of-networks) and you have digital citizens (identities) and digital organizations (networks).
The next question about worlds: how to create value in a universe?
Value is a form of energy. It is called value because it involves a process of evaluation:
Evaluator uses Evaluation determines Value
Understanding this triad is the key to unlocking value, no pun intended.
This is a description of the process. Step one: an entity beholds something that is being offered by another entity. Step two: if the beholder finds the offer useful, if they feel that they would be better off accepting the offer, the beholder is agreeing that there is value in the offered item or service. There may be a step three: negotiating a price and actuating the exchange.
Note that this ultimately means that a value creator comes into being whenever someone perceives value in an offer and then subsequently buys into it. For clarity: the point is that value can be recognized when a purchase occurs.
In simpler terms: a purchase is the only sign of value, and the exchange of the item or service for some form of payment or credit is the value creation process.
Now that we understand what value is, abstract as it is when speaking about it, it is very specific in all situations. This is why anyone can create value for anyone else in very specific ways. The process of value creation, as described above, needs an entity to recognize the value of the creation on offer. Indeed, the patron gives value to the creator in a naturally interdependent relationship. And patrons are defined by their purchases aka patronage.
What we now have is a world within which citizens or citizen entities can create value for each other, and can make offers to each other, as well as effect exchanges if they see value in each other's offers. This means exchanging is a key component of value, and without the ability to exchange, purchases can not happen, which means value can not be recognized.
