# What is a Tier

> A tier is the public-facing dispute profile that packages juror stakes, arbitration fees, and panel size for platforms integrating Justly.

A **tier** is the public-facing dispute profile for a Justly case. It defines the **security level, cost, and robustness** of a dispute.

It packages the main values a platform or integrator cares about, such as:

* how many jurors are targeted,
* how much jurors stake,
* and the arbitration fee amounts required for each side of the dispute.

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 the 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 are targeted for 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 and fees

Tiers establish the economic values for:

* juror stakes,
* the claimer-side funding requirement,
* and the defender-side funding requirement.

Each side must be fully funded before the dispute activates.

Higher values:

* 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.

***

#### 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**.

For integrators, tiers are the main abstraction exposed through the SDK or API.

* 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.
