edge creation, cost becomes a function of time

Outcome: a written description and model of attack cost.
Proof-of-work function is likely to be part of this.

Good intro This problem is known as the Tragedy of the Commons. Everyone
would win if everyone participated, but one person can not make the difference. This concept
was first introduced in In Tribler, this concept exists in the following form: Everyone would like
to use the network to download data. However, in order to do so, there needs to be at least
one agent to relay this data, and then another one to request it from the internet. This means
that if enough agents fulfill these functions out of their free will, and everyone does a little bit,
the load will be spread and the network will fuction. However, it is much more enticing to not
contribute and only consume.
