What is the Definition of Collusion Resistance?

Collusion Resistance is a property of a system where participants cannot conspire to achieve an outcome that benefits them unfairly at the expense of others. In blockchain contexts, this often refers to mechanisms that prevent a group of validators or miners from manipulating transaction order or network consensus. It is a critical characteristic for maintaining the integrity and fairness of decentralized networks.

What is the Context of Collusion Resistance?

Discussions around Collusion Resistance are particularly relevant in the context of Proof-of-Stake and Proof-of-Work consensus models, as well as in the design of decentralized autonomous organizations (DAOs). Analysts evaluate the robustness of a protocol's design against potential cartelization or censorship by a significant portion of network participants, especially during periods of network stress or governance challenges.
