The Challenge

Disputes in the global, digital, and decentralized economy occur in areas where they cannot be solved by state courts and existing dispute resolution methods.

Arrow Pointing Down

The Solution

Kleros connects users who need to solve disputes with jurors who have the skills to fairly settle them. Our resolution layer uses blockchain technology and crowdsourced jurors to adjudicate disputes in a fast, secure, and affordable manner.

The Solution

How Does Kleros Work?

1
Contract

Contract

Users create a smart contract and choose Kleros as its adjudication protocol.

2
Dispute

Dispute

The relevant information is securely sent to Kleros.

3
Selection

Selection

A tribunal is drawn from the crowd. Jurors evaluate evidence and cast their vote.

4
Enforcement

Enforcement

The decision is enforced by the smart contract.

Crowdsourcing taps into a global pool of jurors. Blockchain guarantees evidence integrity and transparency in jury selection. Game theory provides incentives for honest rulings.

Use Cases

Escrow

Arbitration

A freelance job is contracted between two people working cross continent. The service is not rendered to a satisfactory standard and a jury of experts analyze the evidence, vote, and find a verdict.
Social Media

Social Media

An unpleasant comment posted in a decentralized social media platform is deemed to have broken terms and conditions. Kleros jurors rule to deduct reputation points from the user.
Insurance

Gaming

Online gaming is a growing market with superstar players. Professionals will require a highly skilled group of jurors to arbitrate disputes, and for the provision of safe spaces to play in.
Crowdfunding

Crowdfunding

A startup backed by crowdfunders never materialises a viable product. The funds have been locked in a smart contract escrow adjudicated by Kleros jurors and are returned to the investors.
Curated Lists

E-Commerce

A product purchased online does not meet the advertised standard. Kleros adjudicates in favour of the buyer and a smart contract returns the funds.
Oracles

Oracles

“Did it rain in Ulaanbaatar today?” An oracle bridges the gap between the outside world and blockchain allowing smart contracts to use real world data in their outcomes.

Pinakion Token (PNK)

PNK provides jurors an incentive to vote honestly. Users trying to game the system will lose money.

Pinakion Feature

Pinakion protects the system from sybil attacks, while also providing jurors an incentive to vote honestly.
