# Polkadot Relay Chain Token incentives Methodology

## 1. Overview

Token incentives for Polkadot Relay Chain measure the total value of DOT issued as network rewards and ecosystem grants. These incentives primarily consist of staking rewards paid to validators and nominators for securing the network, alongside bounty payments distributed for community-led development and ecosystem initiatives. This metric represents the protocol's issuance-based compensation for its various stakeholders and is analogous to stock-based compensation in traditional finance.

## 2. Data sources

- **Blockchain events**: `Reward` and `Rewarded` events from `staking` pallet and `Claimed` events from `childBounties` pallet, covering Polkadot Relay Chain
- **External data**: End-of-day price feeds for DOT

## 3. Step-by-step calculation

### Component A: Polkadot Relay Chain staking rewards

- **Purpose**: Captures the value of DOT distributed to validators and nominators for maintaining network security and consensus.
- **Logic**: Events are parsed from the `staking` pallet on Polkadot Relay Chain. Specifically, `Reward` events are captured for historical data, while `Rewarded` events are captured for recent data. A logic pivot is applied at block 19,550,701 to account for changes in the underlying event data structure. Staking rewards for this product are tracked on the Relay Chain until the migration of staking operations to Polkadot AssetHub.
- **Key fields**: `amount` (reward quantity), `block_timestamp` (timing)

### Component B: Polkadot Relay Chain bounty claims

- **Purpose**: Captures the value of DOT distributed through the decentralized treasury and bounty system.
- **Logic**: `Claimed` events are parsed from the `childBounties` pallet. Payments are filtered to identify specific bounty distributions by verifying the pallet and method types. The value of each claimed bounty is extracted from the event parameters.
- **Key fields**: `amount` (claim quantity), `block_timestamp` (timing)

### Component C: Normalization and USD conversion

- **Purpose**: Normalizes native asset quantities and converts them to a standardized USD value for reporting.
- **Logic**: All extracted DOT amounts are normalized by decimal precision. These values are then multiplied by the end-of-day price of DOT. Daily totals are aggregated based on UTC day boundaries, and a forward-fill strategy is applied to ensure data continuity.
- **Key fields**: `token_incentives` (USD value), `timestamp` (UTC day)

Token incentives

Blockchains (L1)

Network participants process transactions and receive fees from users (supply-side fees).

Polkadot is a security & interoperability platform for blockchains and applications. Polkadot was founded by Gavin Wood and launched in 2020.

DOT holders own and govern the protocol. They currently take a cut of the total transaction fees paid by users (revenue). Polkadot’s investors include Polychain, IOSG Ventures, Hashkey, etc.
