The Future of Credit Scoring: Reputation-Based and On-Chain

Wallets are pseudonymous, but real-world credit requires identity. Projects like Ethereum Attestation Service (EAS) and Verax are solving this by creating portable, verifiable credentials.

• Soulbound Tokens (SBTs) act as non-transferable proof of history.
• Zero-Knowledge Proofs enable verification without exposing raw data.
• Enables underwriting for the ~1.7B unbanked globally.

Static FICO scores are replaced by dynamic, composable reputation. Protocols like ARCx, Spectral, and Getaverse create on-chain credit scores from DeFi activity.

• Multi-chain data aggregation from Aave, Compound, and Uniswap.
• Scores update in real-time, not monthly.
• Enables permissionless underwriting for lending protocols like Maple and Goldfinch.

Over-collateralization kills capital efficiency. True on-chain credit is the next $100B+ market. It's the logical endpoint for MakerDAO's RWA vaults and Aave's GHO stablecoin.

• Reduces collateral requirements from 150%+ to near 0% for trusted entities.
• Unlocks under-collateralized lending for DAO treasuries and protocols.
• Creates a native yield source detached from traditional monetary policy.

Reputation scores are only as good as their inputs. Sybil attacks on data sources like Gitcoin Passport or ENS can poison the well.

• Off-chain data (KYC, social graphs) requires trusted oracles, creating centralized points of failure.
• On-chain data (DeFi positions, NFT holdings) is vulnerable to flash loan-aided reputation farming.
• A single compromised oracle could collapse the credibility of an entire system like ARCx or Spectral.

Immutability is a curse for reputation. A single bad debt from a Maker vault or a failed Aave liquidation becomes a permanent scarlet letter.

• No "forgetting" mechanism conflicts with real-world credit repair and personal growth.
• Creates perverse incentives: users with permanently tarnished scores have no reason to behave well.
• This undermines the utility of long-tail lending protocols built on these scores.

The core value prop of wallets like Brave or Rabby is privacy. Reputation scoring demands maximal transparency.

• To build a score, you must doxx your entire financial history across addresses, killing pseudonymity.
• Creates a data honeypot for regulators and exploiters, worse than any centralized credit bureau leak.
• Tornado Cash users are automatically excluded, creating a de facto sanctioned financial system.

Issuing undercollateralized credit is a regulated activity globally. Protocols like Goldfinch and TrueFi navigate this carefully.

• A permissionless reputation-based lending pool is an unlicensed bank in the eyes of the SEC or FCA.
• Global enforcement is unpredictable; a crackdown in one jurisdiction could freeze liquidity worldwide.
• Forces protocols to choose between decentralization and survival, a fatal compromise.

Reputation is not a universal standard. A high score on Ethereum means nothing on Solana or Avalanche.

• Cross-chain reputation is unsolved, requiring fragile bridges like LayerZero or Wormhole for data sync.
• Lenders face higher risk assessing unfamiliar scoring models, demanding higher premiums, reducing utility.
• This Balkanization prevents the network effects needed for the system to achieve critical mass.

Why would anyone take unsecured debt when they can post overcollateralization in Maker or Compound?

• The only viable borrowers are those already over-leveraged and unable to post more collateral—the riskiest cohort.
• This creates adverse selection, dooming the first wave of reputation-based pools to high default rates.
• Undermines the core thesis that on-chain reputation can be better than cold, hard crypto collateral.

Current DeFi is a capital-inefficient fortress. Lending requires 150%+ over-collateralization, locking up $100B+ in idle capital. This excludes most of the world from productive credit.

• Capital Inefficiency: Idle TVL earns no yield for the protocol.
• Exclusionary: No path to undercollateralized loans.
• Static: Off-chain credit scores are opaque and non-composable.

Reputation becomes a composable, on-chain primitive. Think EigenLayer for credit—staking your transaction history, on-chain identity (e.g., ENS), and governance participation to build a verifiable score.

• Composability: Scores plug into any DeFi app (Aave, Compound).
• Dynamic: Real-time updates based on wallet activity.
• Sybil-Resistant: Leverages proof-of-personhood from Worldcoin, BrightID.

Technical standards are emerging to formalize reputation. ERC-7281 (xERC20) enables minting/burning tokens based on off-chain data (e.g., credit scores). Soulbound Tokens (SBTs) create non-transferable reputation ledgers.

• Standardization: Enables interoperability across protocols.
• Privacy-Preserving: Zero-knowledge proofs (e.g., zkPass) can verify data without exposing it.
• Immutable Record: SBTs create a persistent, unforgeable history.

The endgame is risk-based interest rates. A wallet with a 2-year history of on-time repayments on Goldfinch or Maple gets a 120% LTV loan instead of 70%. Protocols like Spectral Finance and Cred Protocol are building the risk oracles.

• Risk-Based Pricing: Dynamic rates based on on-chain behavior.
• Capital Efficiency: Unlocks 10-50x more lending volume from same TVL.
• New Markets: SME lending, invoice financing become viable.

Feeding off-chain data on-chain reintroduces the oracle problem. Who attests to a credit score's validity? Chainlink or Pyth? Legal frameworks for decentralized KYC/AML (e.g., Haven1) are untested.

• Data Integrity: Oracle manipulation risks systemic failure.
• Regulatory Attack Surface: Who is the "lender of record"?
• Privacy Laws: GDPR vs. immutable on-chain records.

The true innovation is quantifying trust over time. A wallet's longevity and consistent behavior become its most valuable asset, moving us from collateral-based to reputation-based finance. Early movers are building the graph now.

• New Asset Class: Reputation becomes a yield-bearing, stakable asset.
• Protocol Capture: The scoring standard becomes a moat (like EigenLayer).
• Paradigm Shift: From what you have to what you do.
