What Is a ‘Mining Cartel’ and How Does It Relate to PoW Centralization?

A mining cartel is a secret agreement or collusion between multiple large mining pools or individual miners to collectively control a significant portion of a PoW network's hash rate. While not a single entity, their combined power could reach or exceed the 51% threshold, allowing them to execute attacks or censor transactions.

This represents a centralization risk even if no single pool controls 51% individually.
