# PNK Token

> PNK powers juror staking, governance voting, and 51% attack resistance in Kleros, with market scarcity, price impact, and forking as core defenses.

# PNK Token

**PNK** is the native token of the Kleros protocol. It serves two core functions: **staking for juror eligibility** and **governance voting rights**. Token holders stake PNK to participate in dispute resolution, with higher stakes increasing selection probability, and use it to vote on governance proposals, court parameters, and platform changes.

The name references **Pinakions**, the bronze plates used in Ancient Athens for randomized jury selection.

## Token Supply

The max PNK token supply is **915,528,222.07931277**. Supply changes are controlled exclusively through Kleros DAO governance votes.

* Mainnet contract: [`0x93ED3FBe21207Ec2E8f2d3c3de6e058Cb73Bc04d`](https://etherscan.io/token/0x93ed3fbe21207ec2e8f2d3c3de6e058cb73bc04d)

## What PNK Is Used For

| Function                | How it works                                                                                                                    |
| ----------------------- | ------------------------------------------------------------------------------------------------------------------------------- |
| **Juror staking**       | Stake PNK in a court to become eligible for juror selection. Selection probability is proportional to stake.                    |
| **Incentive alignment** | Coherent jurors earn arbitration fees and PNK redistributed from incoherent jurors; incoherent jurors lose part of their stake. |
| **Governance**          | PNK holders vote on Kleros Improvement Proposals (KIPs), court parameters, and protocol upgrades.                               |

## [Why Kleros Needs a Native Token](https://medium.com/kleros/why-kleros-needs-a-native-token-5c6c6e39cdfe)

PNK's design provides three layers of protection against a 51% [(Sybil) attack](https://en.wikipedia.org/wiki/Sybil_attack):

1. **Market scarcity defense.** Acquiring 51% of PNK becomes economically prohibitive: large purchases exhaust available liquidity and drive the price up, unlike an attack denominated in ETH or another asset with vastly deeper markets.
2. **Price impact risk.** A successful attack would substantially devalue PNK itself, imposing a massive cost on the attacker that does not exist when attacking with an external asset.
3. **Fork capability.** As a last resort, the community can perform an emergency fork that removes the attacker's holdings, a recovery path unavailable with external tokens.
