Kleros

Kleros (PNK) is a cryptocurrency. It functions as a decentralized dispute resolution layer engineered to deliver binding arbitration for the sprawling terrain of Web3 interactions, prediction markets, and digital commerce.

The protocol targets a deeply entrenched friction: the cost, sluggish pace, and jurisdictional opacity of legacy legal systems when applied to borderless, code-governed transactions. By replacing centralized adjudicators with a game-theoretically aligned jury pool, Kleros resolves smart contract failures, escrow deadlocks, and human-coded disputes that traditional courts cannot process without exorbitant friction. Prediction markets and oracle challenges form a significant slice of its early case diversity.

Kleros operates on the Ethereum network, with multi-chain deployments stretching across the Gnosis Chain (formerly xDai) and Arbitrum One Layer-2 rollup. These secondary footholds allow the protocol to offer sub-dollar arbitration costs for low-value claims while retaining the base-layer security guarantees of Ethereum for higher-stakes verdicts. No bespoke consensus mechanism exists beneath it; Kleros inherits finality from the host chains.

The smart contracts conform to the ERC-20 token standard and execute across the Ethereum Virtual Machine, enabling composability with DeFi protocols and wallets. Three distinct verification contracts anchor the token on Ethereum mainnet, Gnosis Chain, and Arbitrum One, each auditable through on-chain explorers. The dispute resolution logic is encoded in a set of open-source court contracts that manage jury selection via a random draw weighted by staked PNK.

The Kleros project originated in France, crystallizing its mechanism in a public whitepaper that lays out a cryptoeconomic theory of decentralized justice. No singular founder dominates the narrative; instead, a distributed cooperative has shepherded the codebase since its early deployment. The public GitHub repository has accumulated 258 stars, reflecting sustained attention from the developer community across audits and incremental protocol upgrades.

The long-horizon aim is to erect a universal, credibly neutral arbitration layer that operates as infrastructural glue for the new economy. Rather than displacing state courts entirely, Kleros aspires to become the default settlement backend for agreements that are born digital—cryptocurrency-collateralized loans, content moderation verdicts in decentralized social networks, and autonomous organization treasury disputes.

PNK functions mechanically as both sybil-resistance barrier and incentive engine. Prospective jurors stake PNK to signal availability, and the protocol randomly selects them to hear cases; staked tokens are at risk of confiscation if a juror votes incoherently against the cryptographically disclosed majority. Coherent rulings earn a distribution of the arbitration fees paid by the disputing parties. Token holders who do not serve can delegate their stake to reliable jurors, passively accruing a yield without active participation.

Jurors actively lock PNK to enter the selection pool for specialized courts, earning a pro-rata share of fees each time they align with the ultimate verdict. Cryptocurrency exchanges and DAO treasuries that integrate Kleros for escrow disputes indirectly drive demand for the token, as every arbitration fee is partially routed to the staking rewards pool. Delegation contracts let non-technical users allocate stake to proven arbitrators, lowering the barrier to participation while preserving the security model.

Kleros has a total supply of 915,528,222.08 tokens. Currently, 724,189,581.45 are in circulation. With a market capitalization of $10,967,264, Kleros ranks #1,161 among all cryptocurrencies.
