Validator Collusion Threshold

The Validator Collusion Threshold is the specific percentage of network stake or computational power that, when combined, allows a group of validators to act maliciously without being effectively challenged. This threshold is determined by the specific consensus rules and the economic penalties associated with bad behavior.

If the combined power of a colluding group exceeds this threshold, they can successfully double-spend, censor specific transactions, or finalize fraudulent blocks. Understanding this threshold is fundamental to behavioral game theory in crypto, as it defines the boundary of rational adversarial behavior.

Protocol designers aim to set this threshold high enough to make collusion economically irrational. Traders and institutions evaluate this threshold to assess the systemic risk of participating in or lending against assets on a specific network.

It represents the tipping point where the security of the protocol is fundamentally compromised.
