Purify your profits from PNK

A portion of profit from PNK isn't fully yours to keep — here's how to return it

What does "purification" mean?

Even fully screened assets can pick up small amounts of tainted income along the way — purification means giving that specific portion back, not paying extra.

Based on Kleros's riba, gharar and maysir screening — see how we calculate purification amounts.

Analyst summary

Kleros is a decentralized arbitration protocol on Ethereum/Arbitrum where PNK holders stake tokens to serve as jurors, drawn randomly to rule on disputes via game-theoretic incentives and coherence-based rewards. Genuine utility exists: 900+ disputes resolved, enterprise pilots in Argentina, Oxford academic ties. The key gap: no named audit firm with a published, dated report could be confirmed for Kleros's smart contracts, despite years of live mainnet operation handling real value. That absence of independent verification, layered atop a 2018 ICO structure with team/investor allocations, is the single biggest Shariah-relevant concern here — not the mechanism itself, which is arbitration, not lending or gambling.

The research

27-point Shariah breakdown of PNK

Islamic Finance Principles Assessment

Riba — Does Kleros involve interest?

Kleros's core function is dispute arbitration, not lending or interest-bearing finance, so riba is not embedded in its base design. Reward flows are tied to arbitration fees and a treasury-funded incentive pool rather than fixed guaranteed interest. For Muslim investors, riba is a secondary rather than primary concern here, though the incentive program's advertised APY figure warrants scrutiny.

Assessment: Moderate Riba Score: 67.5/100

Our methodology examines 10 criteria to evaluate how well Kleros avoids interest-based mechanisms.

Kleros generates revenue through arbitration fees paid by disputants directly to jurors for resolving cases; the protocol itself takes no cut beyond a newly approved 0.05% ETH fee routed to a DAO Treasury Safe (KIP-83), leaving juror rewards untouched. No sources indicate the treasury holds interest-bearing instruments, bonds, or lending positions; the reserve is primarily PNK-denominated (a 12% Cooperative Development Reserve) alongside collected ETH/xDAI fees. This fee-for-service structure, where payment corresponds to actual arbitration labor performed, resembles a service fee rather than interest income, supporting a permissible reading of the revenue mechanism.

Juror rewards derive from two channels: coherence-based arbitration fees (paid only when a juror's ruling matches the majority, i.e., performance-linked) and a supplementary treasury-funded Juror Incentive Program distributing a fixed monthly PNK pool. The latter has been described in one proposal as yielding roughly 9% APY — language that echoes fixed-interest framing and deserves caution, even though it is denominated in PNK from a discretionary pool rather than guaranteed fiat interest. Because actual reward realization still depends on active, coherent participation and case draws (not passive deposit), this leans toward variable, performance-based compensation rather than true riba, though the APY framing should not be ignored.


Gharar — How much uncertainty does Kleros involve?

Uncertainty in Kleros is moderated by strong founder transparency and open-source code but heightened by the absence of a confirmed independent security audit. Overall gharar sits at a moderate level: informational disclosure is good, but technical risk verification is incomplete. Investors should treat this gap as a genuine, not cosmetic, concern.

Assessment: Moderate Gharar (Material Uncertainty) Score: 64.3/100

Our methodology examines 15 criteria including team transparency, audit quality, and governance.

The Kleros team is fully named and publicly traceable: Federico Ast (CEO, Ph.D. in legaltech), Clément Lesaege (CTO, cryptoeconomics background), and William George (Ph.D. mathematics) have years of documented conference appearances, interviews, and academic affiliations (Stanford CodeX, Oxford collaboration). The codebase is open source on GitHub with public documentation and an active governance forum where PNK holders debate and vote on KIPs. This level of identity and process transparency substantially reduces gharar relative to anonymous or opaque projects, and no sources link the team to fraud or rug-pull activity.

Despite years of mainnet operation and enterprise pilots, no named audit firm with a dated, published audit report specific to Kleros's smart contracts could be confirmed in available sources; references to Trail of Bits and Halborn appear only as generic security-resource pages, not verified Kleros engagements. Internal use of tools like Slither and Mythril is noted, but this falls short of independent third-party assurance. For a protocol that has arbitrated real disputes and holds staked value, this is a genuine and material gharar concern that should be stated plainly rather than minimized.


Maysir — Does Kleros involve gambling or speculation?

Kleros is not designed as a gambling or wagering mechanism; it is a dispute-resolution service where jurors are compensated for applying judgment to real cases. Speculative behavior can occur in secondary PNK markets, as with virtually any traded token, but this is a byproduct of trading, not the protocol's design. The core arbitration function itself does not constitute maysir.

Assessment: Moderate Maysir (High Risk) Score: 68.6/100

Our methodology examines 11 criteria to determine whether Kleros is a gambling instrument or a genuine economic tool.

Kleros provides a concrete, productive service: crowdsourced arbitration for token-curated registries, escrow disputes, DAO governance execution, and enterprise/legal use cases, with over 900 disputes resolved and government pilot programs in Mendoza and Junín, Argentina. Jurors are rewarded for applying analytical judgment to evidence and reaching coherent rulings, a process closer to arbitration labor than chance-based wagering. Slashing of incoherent or non-voting jurors further ties outcomes to diligence and accuracy rather than luck, reinforcing that the reward structure compensates verifiable effort and correct judgment.

Genuine utility and multi-year adoption (mainnet since 2018, Oxford academic collaboration, enterprise integrations) distinguish Kleros from purely speculative instruments, and its jurors are drawn into real economic activity rather than zero-sum betting. That said, PNK trades on open secondary markets where short-term speculative trading can occur, as with most listed tokens; this reflects market behavior around the asset, not a flaw in Kleros's own design, and per consistent principle should not by itself push the assessment toward impermissibility. The protocol's own mechanics remain oriented toward productive dispute resolution rather than chance.


The Full 27-Point Screening

1. Legitimacy (4 criteria)

CriterionScoreAnalysis
Team Transparency90/100Founders Ast and Lesaege, plus researcher William George, are named, credentialed, and traceable across multiple public platforms and years of documented activity.
Fraud & Scam Risk70/100No fraud or rug-pull allegations against Kleros itself appear in the sources; unrelated SEC cases concern other projects entirely.
Use Case Legitimacy85/100Sources document genuine adoption in enterprise, government, and Web3 dispute-resolution use cases.
Ethical Practices80/100The protocol's own design is a neutral arbitration service; any third-party misuse of integrations does not reflect the core design and is not determinative.

Summary: Kleros is run by publicly identifiable, credentialed founders with a multi-year traceable track record and no fraud indicators found in these sources.


2. Project Operations (9 criteria)

CriterionScoreAnalysis
Core Protocol Business85/100The base protocol operates in dispute resolution/arbitration, a sector with no inherent prohibition.
Transaction Fees80/100Fees are service payments to jurors for arbitration work, with a newly added minimal, non-dilutive treasury fee rather than interest-like extraction.
Treasury Assets60/100Treasury holds ETH and a PNK reserve with no mention of interest-bearing instruments, though full composition is not disclosed.
Revenue Model80/100Revenue comes from arbitration/service fees, not interest-based lending activity.
Transparency90/100Codebase, documentation, whitepaper, and governance discussions are all publicly available.
Governance60/100DAO governance via KIP voting is real and active, but a sizeable insider/reserve allocation (~30%) tempers full decentralisation.
Launch Fairness55/100The 2018 ICO with early-buyer bonuses and a fixed team allocation is a conventional token sale rather than a fully fair or permissionless launch.
Token Distribution60/100Distribution percentages are well documented, but insiders and reserves retain a meaningful combined share.
Speculation/Utility Ratio80/100Documented enterprise, government, and Web3 integrations indicate utility-driven rather than speculation-driven adoption.

Summary: The protocol is an open-source, DAO-governed dispute-resolution system with fee-for-service economics and a documented, if somewhat insider-weighted, 2018 token launch.


3. Financial Health (4 criteria)

CriterionScoreAnalysis
Protocol Revenue80/100Protocol revenue is service-fee based rather than interest-based.
Financial Status40/100Some staking and TVL metrics are cited, but no full financial statement or stability assessment is available in the sources.
Interest Assessment85/100Kleros functions as a dispute-resolution protocol, not a lending/borrowing platform, and no interest mechanism exists at the protocol level.
Audit Quality15/100 (low evidence)No named third-party audit firm with a specific date and published findings for Kleros could be identified in these sources.

Summary: Kleros earns fee-based (non-interest) revenue as an arbitration service rather than a lending platform, but no confirmed third-party security audit for Kleros itself could be located in the sources.


4. Token Economics (5 criteria)

CriterionScoreAnalysis
Token Purpose80/100PNK has clear functional utility as a staking requirement for jurors and as a governance token.
Governance Rights85/100PNK holders actively vote on protocol proposals affecting fees, incentives, and treasury policy.
Rewards Distribution55/100Rewards mix genuine activity-based arbitration fees with a treasury-funded fixed monthly emission pool described in one proposal with an APY figure.
Speculation Controls65/100Appeal-crowdfunding and slashing of incoherent jurors' stake serve as documented anti-manipulation mechanisms.
Asset Backing55/100The token has no external asset backing; its value is inferred to rest on protocol usage rather than a stated reserve.

Summary: PNK is a genuine utility and governance token whose rewards combine real arbitration-fee income with a treasury-funded fixed emission program, raising a partial but unresolved classification question.


5. Staking Mechanism (5 criteria)

CriterionScoreAnalysis
Mechanism Type75/100Staking is direct and non-custodial through protocol smart contracts with documented juror-draw mechanics.
Islamic Contract Classification45/100Arbitration-fee rewards resemble a service-based contract, but the fixed monthly incentive pool with APY framing introduces ambiguity that the sources do not address in Shariah terms.
Rewards Structure50/100Rewards blend genuine variable arbitration-fee income with a quasi-fixed monthly PNK emission pool.
Documentation80/100Staking mechanics, slashing rules, and incentive formulas are thoroughly documented in governance proposals and docs.
Shariah Alignment45/100The coexistence of genuine service-fee rewards with a fixed-pool, APY-labelled emission program leaves an unresolved question about whether part of the return functions as a guaranteed increment.

Summary: Kleros has a well-documented native, non-custodial staking mechanism with slashing, though its reward blend of fee income and fixed-pool emissions is not clearly resolved from an Islamic contract perspective.


Overall Assessment: Kleros appears to be a legitimate, utility-driven dispute-resolution protocol with transparent governance and team, whose main open Shariah-relevant questions concern the character of its staking-incentive emissions and the absence of a confirmed independent security audit.
