Building Collusion.app: An Anonymous Coordination Mechanism

We recently shipped Collusion.app during an intense 48-hour weekend sprint. The application addresses a fundamental problem in academic and research environments: social coordination failures among highly introverted individuals.

Introverted scientists often want to socialize, but only if they are guaranteed a comfortable group density. Collusion.app solves this with a Blind Commitment Engine.

The Cooperative Binding Logic

Guests register their availability and a "minimum comfort threshold" (e.g., "I will only attend if at least 3 other people commit").

The system hides all names, commitments, and counts until the mathematical quorum is satisfied.

// The core Collusion quorum resolution logic
function evaluateQuorum(optionId, commitments) {
  const optionCommits = commitments.filter(c => c.optionId === optionId);
  const totalCommits = optionCommits.length;
  
  if (totalCommits > 0) {
    const maxThreshold = Math.max(...optionCommits.map(c => c.minThreshold));
    if (totalCommits >= maxThreshold) {
      return { resolved: true, size: totalCommits };
    }
  }
  return { resolved: false, size: totalCommits };
}

By hiding voter density and identity prior to resolution, we insulate users from social pressure, eliminating the fear of being the "sole committed guest" and preventing deadlock. Once the threshold is met, the system triggers a state transition, locking in the event and revealing the participants.
