## 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](https://coinmarketcap.com/alexandria/glossary/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](https://coinmarketcap.com/currencies/erc20/) 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.

Ampleforth is an Ethereum-based cryptocurrency with an algorithmically adjusted circulating supply. It is designed to be the base money of the new decentralized economy, by providing an asset that cannot be diluted by supply inflation and remains decoupled to the price action of other cryptocurrencies—and Bitcoin (BTC) in particular.

With Ampleforth, token holders own a fixed fraction of the total AMPL circulating supply, rather than a fixed number of tokens. When the protocol detects that the price of AMPL is too high, it increases the circulating supply, whereas the supply is decreased if the price is too low.

This change is propagated to all Ampleforth wallets, which have their wallet balance adjusted proportionally. Irrespective of this change, AMPL holders will still retain the same percentage of the token supply.

This automatic supply adjustment process is known as a “rebase” and occurs once each day, with a positive rebase if the price goes above $1.06, and a negative rebase if it is below $0.96. The overall goal of the system is to create incentives that drive the market price of AMPL back to ~$1.

ABBC is a blockchain platform that enables secure payment transactions, helping to facilitate retail adoption of cryptocurrencies and make shopping online with digital assets a safer, more enjoyable experience for end-users.

The platform offers three main products: a multi-platform wallet capable of supporting Bitcoin (BTC) and Ethereum (ETH), in addition to a variety of other native cryptocurrencies and ERC-20 tokens; an online shopping application that can be used to shop at over 50 online retailers with cryptocurrencies; and a cryptocurrency exchange platform that offers secure trading and low transaction fees.

The ABBC Coin was created to give holders the ability to govern the development of the ABBC platform by delegating voting power to chosen block producers (BPs) — who are then able to vote on governance proposals. These governance proposals can be on a range of topics but might include launching strategic partnerships, implementing new features or expanding ABBC's services to new regions. Beyond this, ABBC Coins were created as a reward system for online shoppers and can be staked for regular rewards.

ABBC is currently based on the EOSIO blockchain, which enables it to achieve up to 5,000 transactions per second (TPS) while remaining environmentally friendly due to its energy-efficient delegated proof-of-stake (DPoS) consensus mechanism.

ABBC Coin was initially known as Alibabacoin but changed its name in March 2019 following a dispute with Chinese multinational e-commerce giant Alibaba.

Billed as a "network of decentralized markets and communities," district0x is a platform that allows users to easily launch their own decentralized platforms which are governed by a decentralized autonomous organization (DAO) structure.

Each of these platforms is termed a “district” and can be launched free of charge on the district0x. The ecosystem is powered by the custom d0xINFRA framework, which provides a set of basic smart contracts and libraries users can use when building out their districts — enabling a wide array of potential use-cases.

The native token of the district0x ecosystem is DNT — an ERC-20 utility token that is mostly used for community governance.

The platform uses a combination of three main technologies: Ethereum, Aragon and the InterPlanetary File Transfer Protocol (IPFS).

The Ethereum blockchain is used for hosting districts, whereas Aragon is used as the governance layer for the district0x network, allowing DNT stakers to benefit from governance rights and help shape the development and operation of their chosen districts. Lastly, IPFS is used for serving the district0x website source code and for user uploads within districts.
