Jurors receive arbitration fees for reviewing evidence and voting coherently on disputes (supply-side fees).

Kleros is a third party arbitration and dispute resolution system built on Ethereum and Gnosis. Kleros was founded by Federico Ast, Clémenet Lesaege and Nicolas Wagner, and was launched in 2019.

PNK tokenholders own and govern the protocol. They do not currently take a cut of the total fees taken by coherent jurors (revenue).

# Kleros Token incentives Methodology

## 1. Overview

The Kleros token incentives metric measures the daily amount of PNK tokens distributed as rewards to participants in the Kleros ecosystem. This includes incentives paid to jurors for participating in decentralized arbitration cases and rewards for contributors to the tag registry system. The metric captures both types of incentives, converts them to USD values, and aggregates them by day to show the total incentive spending by the protocol.

## 2. Data sources

- **Ethereum event logs**: Parsed `MerkleRedeem_Claimed` events from the Kleros v1 MerkleRedeem contract on Ethereum
- **Gnosis chain token transfers**: Token transfer events from Gnosis chain for PNK token distributions
- **End-of-day price feeds**: Token price data for USD conversion
- **Token metadata**: Decimal precision information for proper token amount calculation

## 3. Step-by-step calculation

### Component A: Juror incentives
- **Purpose**: Captures incentives paid to jurors for participating in Kleros arbitration cases
- **Logic**: Extracts data from Ethereum `MerkleRedeem_Claimed` events emitted by the Kleros v1 contract. Filters out any removed events to ensure data quality. Uses the `balance` field from these events as the raw incentive amount. Maps all records to the 'Decentralized Court' business line with 'infrastructure' market sector classification. Associates incentives with the PNK token address `0x93ed3fbe21207ec2e8f2d3c3de6e058cb73bc04d`
- **Key fields**: `balance` (incentive amount), `account_address` (recipient), `block_timestamp` (timing), `token_address` (PNK token)

### Component B: Tagging incentives  
- **Purpose**: Captures rewards distributed to contributors of the Kleros tag registry system
- **Logic**: Extracts token transfer events from Gnosis chain where transfers originate from the specific distributor address `0xd0e76cfaa8af741f3a8b107eca76d393f734daces`. Filters for transfers of the PNK token (Gnosis address `0xcb3231aba3b451343e0fddfc45883c842f223846`) and maps them to the equivalent Ethereum token address for consistency. Uses the transfer `value` as the incentive amount. Applies the same business classification as juror incentives
- **Key fields**: `value` (transfer amount), `from_address` (distributor), `to_address` (recipient), `token_address` (mapped to Ethereum PNK)

### Final aggregation
- **Combining components**: Both juror and tagging incentives are unioned together with identical schema structure, creating a unified dataset of all PNK incentive distributions
- **Currency conversion**: Raw token amounts are converted to USD using end-of-day price feeds through the convert_to_usd_and_correct_decimals macro, which also corrects for token decimal precision
- **Time aggregation**: All timestamps are truncated to daily boundaries using timestamp_trunc, ensuring consistent daily aggregation
- **Final calculation**: The metric represents the sum of all USD-converted incentive amounts distributed each day across both juror rewards and tagging rewards, with missing dates filled with zero values to maintain complete time series continuity
