Definition
A Schelling point (or focal point) is a choice that multiple parties tend to select independently, without being able to communicate, because it stands out as the obvious or salient option. The concept was introduced by economist Thomas Schelling in The Strategy of Conflict (1960). His classic example: strangers told to meet in New York City on a given day, with no way to coordinate, disproportionately chose noon at Grand Central Terminal — not because it is correct, but because it is mutually conspicuous.
Relevance to Decentralized Systems
Schelling points are foundational to how leaderless systems coordinate. In a network with no central authority dictating the rules, participants must independently converge on the same answer to questions like "which chain is the real one?" or "which is the legitimate set of consensus rules?" The longest valid chain in proof-of-work, or a widely-shared social consensus about money's properties, can act as a focal point that honest participants gravitate toward without negotiation.
Money as a Schelling Point
Monetary theorists describe sound money itself as a Schelling point: among many possible stores of value, people coordinate on whichever asset others are most likely to also recognize and accept. This self-reinforcing salience is part of why monetary networks can be sticky. Focal points are culturally dependent, however — what is obvious to one group may not be to another — so they are a coordination heuristic, not a deterministic rule.
For related coordination and adoption dynamics, see network effect and Metcalfe's Law.
