Welcome to Kleros.

So, you'd like to become a Kleros juror!

The process is quite simple. There is no personal information needed and there is no registration process - in short, all you have to do is get your PNK ready and stake in our courts!

To help in the process of getting you up to speed, here is our full fledged Kleros Juror Starter Kit.

Understanding How Kleros Works

Kleros works in a simple way. The disputes created on the T2CR and the Kleros Escrow platform are immediately sent to the Kleros Court, which is our juror interface. We call the T2CR and the Kleros Escrow the dApps on the "arbitrable side". As a juror, you will be using the arbitrator platform, which is the court.

The Token2 Curated List is a community run, fully decentralized list, displaying all valid tokens in accordance with the established listing guidelines. If some token submission is invalid according to the guideline, users are incentivized to challenge it and the case is brought in front of a Kleros jury.

The Kleros Escrow is a trust backed escrow platform with integrated decentralized dispute resolution. With the Kleros Escrow, a user is able to transact within the blockchain ecosystem for services, products and assets while resting easy, and if there is a dispute, Kleros jurors adjudicate the case. The Kleros Escrow can immediately be used for securing OTC transactions, marketing services, video and written production contracts and more.

The structure of the Kleros subcourts. Cases are adjudicated in subcourts by jurors, following a principle of specialization.

Becoming a Juror

In order to become a juror, there is no sign up, no personal information needed. The only thing you need are the proper tools and your own skills.

The basic outline of what needs doing to become a Kleros juror, in short.
  1. Tooling - to start using the Kleros Court, you first need to get a Metamask wallet and buy some PNK.

At this moment, Kleros operates two subcourts, the Non-Technical Court (low stakes), shared by the Kleros Escrow and the Token Listing Court (high stakes) for the Ethfinex Badges. Find out here more information about how the T2CR works. For more information on how the Escrow works, look here.

So you’ve taken a look at the courts. Where should you stake your PNK? Well, if you have a basic knowledge of blockchain technologies, you might want to stake in the low stake Non-Technical court and adjudicate cases there. If you have a more deeper insight into the workings of crypto, you should probably try out the high stakes Token Listing Court.

Once you’ve taken a look at the courts, what remains is to stake your PNK and wait a bit to get drawn. The juror process looks something like this:

  • Go to the Kleros Court. In the header, click on the ‘Courts’ tab, then click on ‘Browse’.
  • In the next screen you will see the default ‘General Court’ selected. This is the parent court, so you can click down the subcourt tree through the ‘Blockchain’ subcourt to ‘Non Technical’ and then ‘Token Listing’.
  • Once you picked either of the latter two, you can click on the large blue button that says ‘Stake’. Note: Once you stake in a certain court, you are automatically staked in all courts above it up to the General Court. This is for purposes of appeals, primarily.
  • When the ‘Stake’ button is clicked, you can set the amount of PNK you would like to put into the system. The chances to be drawn as a juror depend on the amount of PNK you stake. The minimum stake in the lower stake Non-Technical Court is at this moment 15.000 PNK, while the higher stake Token Listing Court has a minimum stake of 80.000 PNK.
  • Pay the gas fee in Metamask to confirm the staking transaction.
  • Once the fee is paid and the transaction confirmed you can return to the 'Courts' page and see your staked PNK in the court you have chosen. Below, we can see a user has staked a far larger amount of PNK than the court minimum. This gives that juror a far higher chance of being drawn on cases in this court.
  • In the below image, you get an overview of the reward each juror will receive by voting 'coherently' along with the minimum stake of the court, and amount of PNK locked in active cases. In the below example, the juror has been drawn as a juror and has 3750 PNK locked meaning they are unavailable until the end of the dispute.
  • If you are successfully drawn as a juror you will see something similar to the below in your 'cases' page. Users can be notified to any cases, challenges or changes in state of a dispute by signing up using the email icon in the menu header.

If you have been selected as a juror, you will see the information presented below. By clicking 'See Details' you can then review the case, evidence and make your vote.

  • Once the case details are open, you will be able to see the dispute in question (in this case an incorrectly uploaded token submission on the Token Curated List) which presents the evidence from both parties.
  • On the left side, we see the evidence of the submitter and on the right, the evidence of the challenger. Here we can also see a broken image link where the token logo should be. The challenger has specified this in their evidence as seen in the pop-up below.
The case open with evidence, submitter and challenger information. 

9. After the evidence period of two days passes (this is the period in which both challenger and submitter can submit evidence) you will be able to vote on the case.

Before you vote, review the policies carefully.

Jurors can also refuse to arbitrate in the case of illegal, immoral or similar content in the case or evidence.

Until the evidence period is passed the buttons will be greyed out as shown above.

If you have questions regarding the T2CR or the Escrow courts, or would just like to reach out to fellow jurors, feel free to drop a message on our Telegram, or vibrant community will be at your disposal.
