# Appeals Process

The appeals process in GenLayer is the Optimistic Democracy mechanism for correcting errors or disagreements in the validation of Intelligent Contracts. Participants can challenge an initial validation decision so non-deterministic transactions are reassessed, helping preserve the platform's robustness and fairness.

## How It Works

- **Initiating an Appeal**: Participants can appeal the initial decision by submitting a request and a required bond during the Finality Window. A new set of validators is then added to the original group to reassess the transaction.

- **Appeal Evaluation**: The new validators first review the existing transaction to decide if it needs to be overturned. If they agree it should be re-evaluated, a new leader re-evaluates the transaction. The combined group of original and new validators then review this new evaluation to ensure accuracy.

- **Escalating Appeals**: If unresolved, the appeal can escalate, doubling the number of validators each round until a majority consensus is reached or all validators have participated.

Once a consensus is reached, the final decision is recorded, and the transaction's state is updated. Correct appellants receive a reward, while those who are incorrect may lose their bond.

## Gas Costs for Appeals

The gas costs for an appeal can be covered by the original user, the appellant, or any third party. When submitting a transaction, users can include an optional tip to cover potential appeal costs. If insufficient gas is provided, the appeal may fail to be processed, but any party can supply additional gas to ensure the appeal proceeds.
