Kleros Introduction
Kleros is a decentralized arbitration platform built on the Ethereum blockchain. It aims to provide a fast, inexpensive, and decentralized dispute resolution mechanism for smart contracts. The project leverages game theory and blockchain technology to ensure that jurors are incentivized to rule cases correctly. By doing so, Kleros seeks to facilitate a wide range of applications, from e-commerce and finance to international trade and intellectual property disputes, providing a reliable alternative to traditional legal systems.

Description: What Does Kleros Do?
Kleros is designed to function as a decentralized arbitration service for resolving disputes in smart contracts. The primary objective is to provide a fast, inexpensive, and decentralized way to render judgments, leveraging the Ethereum blockchain to facilitate this process. The platform uses game-theoretic incentives to encourage jurors to make correct decisions, aiming to offer a reliable and decentralized alternative to traditional dispute resolution mechanisms.
To achieve these objectives, Kleros employs a multipurpose court system where every aspect of arbitration—from securing evidence to selecting jurors—is automated. The methodology relies on crowdsourcing, blockchain, and game theory to ensure that the system remains secure and cost-effective. Jurors are selected based on a staking mechanism, and the platform uses cryptographic methods to ensure the integrity and randomness of selections.
Problem: Why Kleros Is Being Developed?
The development of Kleros is motivated by the need for a reliable and decentralized dispute resolution mechanism in the digital economy. Traditional legal systems are often too slow, expensive, and jurisdictionally limited to handle the complexities of global, decentralized transactions. This problem affects individuals and businesses operating across national boundaries who need quick and fair resolutions to disputes.
Current solutions, such as centralized arbitration services, are plagued by inefficiencies and high costs. These limitations make it difficult for smaller transactions to be resolved fairly, leaving many without access to justice. Kleros aims to address these issues by providing a decentralized alternative that leverages blockchain technology and game theory to ensure fair and efficient dispute resolution.
Use Cases
- Escrow Services: Kleros can arbitrate disputes in escrow agreements, ensuring that funds are released fairly based on the terms of the contract.
- Microtasking Platforms: Platforms similar to Amazon Mechanical Turk can use Kleros to resolve disputes between taskers and requesters.
- Insurance: Kleros can arbitrate claims in decentralized insurance platforms, ensuring that valid claims are paid out fairly.
- Oracles: Kleros can be used to resolve disputes in decentralized data feeds or oracles.
- Curated Lists: Kleros can manage whitelists and blacklists for various applications, ensuring that only approved entities are included.
How Does Kleros Work?
Kleros operates as a decentralized application on the Ethereum blockchain, consisting of several key components:
- Juror Selection: Jurors are selected based on a staking mechanism where they stake a specific token called Pinakion (PNK). The probability of being selected as a juror increases with the amount of PNK staked.
- Dispute Resolution Process: Once a dispute arises, it is submitted to the Kleros platform. Jurors are then randomly selected to review the evidence and render a decision.
- Incentive Mechanism: Jurors are incentivized to vote honestly through a reward system. Jurors who vote in line with the majority are rewarded, while those who vote incoherently lose part of their stake.
Here is a sequential breakdown of the process:
- Initiation: A dispute is submitted to Kleros, and a fee is paid.
- Staking: Potential jurors stake their PNK tokens to participate.
- Selection: Jurors are randomly selected based on their staked PNK.
- Voting: Jurors review the evidence and submit their votes.
- Revelation: Votes are revealed and checked for consistency.
- Resolution: The majority vote determines the outcome, and rewards are distributed accordingly.
Technical Details
Kleros leverages the Ethereum blockchain and uses a Proof of Stake (PoS) mechanism for juror selection. The platform employs cryptographic methods to ensure the integrity and randomness of juror selection, making it resistant to manipulation.
- Blockchain: Ethereum
- Consensus Mechanism: Proof of Stake (PoS)
- Innovations: Uses game-theoretic incentives, cryptographic randomness, and automated arbitration processes.
Novel technologies include:
- Pinakion (PNK): A token used for staking and selecting jurors.
- Schelling Point Mechanism: Ensures jurors vote honestly.
- Random Number Generation: Uses cryptographic methods to ensure randomness in juror selection.
Kleros Tokenomics: Token Utility & Distribution
The Kleros ecosystem uses the Pinakion (PNK) token, which serves multiple purposes:
- Juror Staking: PNK is staked to increase the likelihood of being selected as a juror.
- Incentives: Jurors are rewarded in PNK for voting honestly.
- Security: PNK helps secure the system against Sybil attacks.
The distribution strategy is designed to ensure broad participation and security:
- Initial Distribution: Tokens are distributed through an initial coin offering (ICO) and other methods.
- Staking Rewards: Jurors earn PNK for participating in the arbitration process.
- Incoherent Voting Penalties: Jurors lose PNK if their votes do not align with the majority.
Key Kleros Characteristics
Kleros aligns with core blockchain characteristics in several ways:
- Decentralization: Operates as a decentralized application on Ethereum.
- Anonymity and Privacy: Uses cryptographic methods to ensure privacy.
- Security: Employs game-theoretic incentives and cryptographic randomness.
- Transparency: All arbitration processes are transparent and recorded on the blockchain.
- Immutability: Once recorded, arbitration outcomes cannot be altered.
- Scalability: Designed to handle a large number of disputes across various domains.
- Supply Control: The supply of PNK is controlled to ensure stability.
- Interoperability: Can interact with various smart contracts and decentralized applications.
