2. Betweenness (β)
In practical terms, the Betweenness of an individual in the Web3 ecosystem represents how well connected they are, and how "central" an individual is for their connections. It's based on a simple, progressive score, that quantifies this "social score" based on how close everyone is to all the others they are connected to.
It's simply calculated by using this formula:
Where:
is the Betweenness of j, based on the amount of connections they have with their peers, weighed by the Proximity Level of those connections
N is the number of Proximity Levels, in this case, 4:
are the number of connections at each Proximity Level (PL)
are the weights corresponding to each Proximity Level,
with ,
and a weight of:
is the total number of connections across all levels
