A video walkthrough of Kleros prototype. This version is built for cases where jurors have to decide between two options.

Governance

Arbitration fees should give jurors a fair reward for their work. Compensation for work done in a very specialized subcourt requiring substantial effort and special skills should be higher than that for a court that doesn’t require such effort and skills.

Non-binary and even non-linear outcomes

If there is a dispute between Alice and Bob, a freelancer that she has hired, the jurors should certainly have the ability to pay Bob or reimburse Alice. But maybe they should also be able to give Bob more time to finish the work.

Nicolas de Condorcet (1743–1794) was a French philosopher, mathematician and political scientist. He developed a voting system known as the Condorcet method which selects the candidate who would beat each of the other candidates in a run-off election. Some of our current research ideas are based on Condorcet’s work.

Oracles

A key application of Kleros is to oracles. Kleros allows to bring knowledge of the real world (the correct party in some dispute) onto the blockchain. This can be leveraged to bring more general information on-chain.

Experiments

Once we have a substantial number of real cases being judged by real jurors motivated by real financial incentives, it will be interesting to observe how participants actually act, how that conforms to game theoretical models, and what are the implications for Kleros.

Zero-knowledge elements

Schelling points are heavily influenced by what information parties have access to. However, on Ethereum, information added to the blockchain is publicly visible, so controlling the information jurors have access to is a complicated problem.

The Strategy of Conflict. Originally published in 1960, this book pioneered the study of bargaining and strategic behavior in situations of conflict. In this book, Schelling introduced the concept of focal point, which many people know today as Schelling Point.

Arbitration fee insurance

We can imagine attacks where a very well-financed attacker attempts to appeal a decision until the opponent just doesn’t have the resources to continue to pay appeal fees. Then even though arbitration fees are reimbursed to the party who is eventually ruled correct (so if the correct party kept going she would eventually be reimbursed) a correct party may be forced to give up due to lack of resources.

Building upon Ethereum scaling solutions

As different scaling solutions are developped for Ethereum, including Plasma, generalized state channels, Truebit, etc., we will think about how to adapt Kleros to best build on these advances in order to optimize gas costs and minimize delays while maintaining security.

Kleros and traditional arbitration

Bringing in ideas from game theory and blockchains allows us to approach dispute resolution from a radically new perspective.
