A tier defines the security level, cost, and robustness of a dispute in Justly. In the current implementation, the same goals are achieved through configurable courts/categories. Standardized tier profiles are part of the protocol roadmap. Tiers allow the protocol to adapt to different types of conflicts by balancing:
  • resolution speed,
  • required level of trust,
  • and the economic risk assumed by both parties and jurors.
Each dispute is executed within a specific tier, and all rules of the resolution process are determined by that tier.

​
What Changes Between Tiers

​
1. Number of Jurors

Each tier defines how many human jurors participate in resolving a dispute.
  • Lower tiers use fewer jurors, enabling faster and lower-cost resolutions.
  • Higher tiers use more jurors, increasing diversity of judgment and reducing the likelihood of biased outcomes.
A higher number of jurors increases the robustness of the result against individual errors or adversarial behavior.

​
2. Stakes

Tiers establish the required stake amounts for both:
  • the parties involved in the dispute (claimer and defender),
  • and the jurors participating in the vote.
Higher stakes:
  • increase the cost of malicious behavior,
  • raise the economic commitment of participants,
  • and better align incentives when the value or complexity of the dispute is higher.
Stake determines economic exposure and incentives for participation.

​
3. Security Level

The security level of a dispute increases as the tier becomes higher. This is driven by the combination of:
  • a larger number of jurors,
  • higher economic stakes,
  • and a greater total cost required to manipulate the outcome.
Together, these factors make higher tiers more suitable for:
  • higher-value disputes,
  • more complex cases,
  • or situations where an additional level of confidence is required.

​
Tier System Design

Tiers do not exist to segment users, but to offer security options proportional to the risk of a given conflict. In the current implementation:
  • tiers are fixed and predefined by the protocol,
  • all disputes within the same tier follow exactly the same rules,
  • and outcomes are executed automatically and verifiably on-chain.
This design ensures predictable behavior for both individual users and platforms integrating Justly.
