Metcalfe's Law posits that the value of a network is proportional to the square of the number of its connected users. This principle suggests that as more users join a network—be it a social media platform, messaging app, or blockchain—the potential connections and overall value of the network increase exponentially rather than linearly. This exponential growth in value underscores the importance of user acquisition strategies for network-based businesses, as each additional user significantly enhances the network's utility and attractiveness.
