About

What Is Kleros (PNK)?

Kleros (PNK) is a decentralized dispute resolution project that launched in July 2018. It is an open-source online dispute resolution protocol that uses blockchain and crowdsourcing to adjudicate disputes fairly.

Kleros offers a middleman service for decentralized applications (DApps) and their users. If the service provided by the application does not create a dispute, Kleros acts as a trustless third-party service for payment.

When a dispute does occur, however, each party can apply for arbitration through the Kleros arbitrators that are selected from the owners of PNK tokens. PNK is an Ethereum-based ERC-20 utility token with a fixed supply.

At this point, the jurors can make a decision that will favor either party. The arbitration fees are distributed to all arbitrators in the form of ETH; jurors who have issued a minority decision lose part of their PNK tokens for the benefit of the majority of jurors. This decision can be appealed, at a cost. The stated mission of Kleros is to offer easier access to justice and improve individual freedom.

Kleros charges a cost that is payable in ETH and is provided by the parties to the dispute or drawn from the funds previously locked in escrow.

Who Are the Founders of Kleros?

Kleros (PNK) was founded by Federico Ast, Clément Lesaege and Nicolas Wagner.

Federico Ast is the CEO of Kleros and a lecturer on Coursera. Before that, he worked as a creator and evangelist at Crowdjury, and was a journalist, speaker, and blogger at Clarín.

Clément Lesaege is the CTO at Kleros. Before Kleros, he worked as a smart contract security freelancer and used to be a research intern in machine learning at Technicolor.

Nicolas Wagner is the lead developer at Kleros. He also works as a freelance web and blockchain developer. In the past, Wagner worked as a blockchain developer at Dether.io and a back-end developer at Tradelab Programmatic Platform.

What Makes Kleros Unique?

Kleros is designed primarily for DApps, however, it is a decentralized and inexpensive arbitration system that could attract attention from outside of the blockchain industry. It is designed to be a multipurpose dispute resolution platform that can function as a legal adjudication service in many cases.

This includes escrow dispute resolution, social network policy violations, and oracle resolutions. The PNK token plays an important role in all of these due to the fact that the amount which is deposited by jurors is directly correlated to the probability of them being selected for a case.

It also functions as the economic incentive for jurors to be honest in cases. PNK also gives them voting power which is tied to the number of tokens they hold. This incentivizes owners to hold tokens for governance purposes, as jurors are also paid in ETH on a case-by-case basis in the form of arbitration fees.

How Many Kleros (PNK) Coins Are There in Circulation?

Kleros (PNK) has a circulating supply of 599,684,715 PNK as of February 2021, with no maximum supply data available at the time.

How Is the Kleros Network Secured?

Kleros relies on cryptography and blockchain for securing the evidence, selecting the jurors and incentivizing honest decisions. The protocol token represents the right of users to be drawn randomly as jurors. Since PNK is an ERC20 token, it can be stored on many offline or desktop crypto wallets that support Ethereum, allowing for a high level of security.

What is the Kleros (PNK) cryptocurrency good for? What are its main use cases?

Kleros (PNK) is a cryptocurrency that is primarily associated with a decentralized dispute resolution platform. It utilizes blockchain technology to provide a fair and efficient means of resolving disputes through a network of jurors. Here are some of the main use cases and functionalities of Kleros:

  1. Dispute Resolution: Kleros serves as a decentralized arbitration service for various applications, including e-commerce, freelancing platforms, and any situation where disputes might arise. Users can submit disputes to Kleros, where jurors (who are incentivized to make fair judgments) will evaluate the evidence and reach a decision.

  2. Token Staking: PNK tokens are used for staking. Jurors must stake a certain amount of PNK to participate in the arbitration process. This staking mechanism helps ensure that jurors act responsibly, as they risk losing their staked tokens if they are deemed to be making poor judgments.

  3. Incentives for Jurors: Jurors receive rewards in the form of PNK tokens for participating in disputes and making accurate decisions. This creates a financial incentive for jurors to remain impartial and to make well-informed judgments.

  4. Decentralized Governance: PNK holders may have governance rights within the Kleros ecosystem, allowing them to participate in decision-making processes regarding the development and rules of the platform.

  5. Integration with Other Platforms: Kleros can be integrated with various decentralized applications (dApps) and platforms that require dispute resolution services. This includes decentralized finance (DeFi) platforms, online marketplaces, and gaming applications, among others.

  6. Crowdsourced Juror Pool: The platform leverages a crowdsourced group of jurors from around the world, which helps reduce biases and contributes to a more diverse set of perspectives when resolving disputes.

  7. Trustless Environment: Kleros aims to provide a trustless and transparent way to resolve disputes, removing the need for a centralized authority and fostering trust in peer-to-peer transactions.

Overall, Kleros (PNK) aims to streamline and enhance the dispute resolution process in a variety of contexts, making it an important component of the broader decentralized ecosystem.

How fast are Kleros transactions? What is the typical confirmation time and throughput (transactions per second)?

Kleros is a decentralized, blockchain-based dispute resolution platform that utilizes the Ethereum blockchain and the Polygon (MATIC) network.

The speed of Kleros transactions is dependent on the underlying blockchain network. On Ethereum, the typical confirmation time can range from 15 seconds to several minutes, depending on the network congestion and the gas price used for the transaction.

For the Polygon (MATIC) network, the confirmation time is generally faster, typically ranging from 1-5 seconds.

As for the throughput, the Ethereum network can process around 15-30 transactions per second (tps), while the Polygon network has a much higher throughput, with the ability to process up to 65,000 tps.

Please note that these numbers may vary depending on the current state of the network and the specific use case. It is always a good idea to check the current network conditions and transaction fees before using the Kleros platform.

How much data can I store on the Kleros blockchain? Does it support on-chain data storage?

Kleros is primarily a decentralized arbitration service designed to resolve disputes using blockchain technology, particularly on Ethereum. However, it is not designed for large-scale data storage. Kleros typically uses the blockchain to store essential arbitration-related data, such as evidence submissions, case details, and jury decisions, but significant amounts of data can't be stored directly on the blockchain due to costs and efficiency concerns.

On-chain data storage on Ethereum (which Kleros operates on) can be expensive, as each byte of data stored incurs gas fees. As such, Kleros and many dApps often utilize off-chain storage solutions (like IPFS or centralized databases) for larger files or data and only store hashes or references on-chain to maintain integrity and accessibility without burdening the blockchain.

In summary, while Kleros does handle essential on-chain data related to its arbitration processes, it is not meant for large-scale data storage, and users often employ off-chain methods for that purpose.
