Why On-Chain Reputation is the New Credit Score

Over-collateralization is a $50B+ capital efficiency sink. It excludes high-quality borrowers without liquid assets, capping the total addressable market for lending protocols like Aave and Compound.\n- Capital Inefficiency: Locks 150%+ value for simple loans.\n- Exclusionary: No path for "credit-worthy but asset-light" users.

Transform on-chain history—repayment streaks, governance participation, fee generation—into a soulbound reputation score. This becomes a new primitive for underwriting, similar to EigenLayer's restaking but for identity.\n- Composable Data: Protocols like Gitcoin Passport and Renaissance aggregate signals.\n- Sybil-Resistant: Proof-of-personhood and persistent history deter gaming.

Smart contracts encode underwriting logic directly. A user's reputation score can automatically adjust loan terms on platforms like Goldfinch or Maple Finance, enabling dynamic LTV ratios and interest rates.\n- Automated Risk Pricing: Real-time adjustments based on wallet activity.\n- Default Protection: Automated liquidation of staked reputation or linked assets.

A user's reputation becomes a portable asset across DeFi. A good borrowing history on Aave could unlock undercollateralized leverage on GMX or better rates on Uniswap pools.\n- Cross-Protocol Utility: Builds a positive feedback loop for responsible users.\n- Protocols as Oracles: Each dApp contributes data to a shared graph (e.g., CyberConnect, Rarimo).

Full transparency leaks alpha and creates discrimination vectors. ZK-proofs (via Sismo, Polygon ID) allow users to prove creditworthiness without revealing exact transaction history or balances.\n- Selective Disclosure: Prove "score > X" without exposing data.\n- Regulatory Compliance: Enables KYC/AML proofs without doxxing.

The endgame isn't just human borrowers. AI agents and smart wallets with proven on-chain operational history will secure credit for gas, trading, and deployments. This requires a native, machine-readable reputation system.\n- Agent-to-Agent Lending: Autonomous market makers like UniswapX resolvers as borrowers.\n- Continuous Underwriting: Real-time scoring for flash loan-like continuous operations.

Overcollateralization locks up $10B+ in idle capital across DeFi. It's a primitive solution that excludes uncollateralized lending, the backbone of traditional finance.

• KYC is not enough: It's a binary gate, not a dynamic risk score.
• Sybil resistance is broken: A fresh wallet with ETH is treated the same as a 3-year OG.

Protocols like EigenLayer, Karma, and ARCx transform your transaction history into a stakeable, portable reputation score.

• Programmable Trust: Your score becomes a parameter for loan terms, validator selection, or governance weight.
• Soulbound & Composable: Attached to a Soulbound Token (SBT) or non-transferable NFT, usable across any integrated dApp.

EigenLayer doesn't just restake ETH; it restakes reputation. Operators with a proven track record are preferentially selected to secure new Actively Validated Services (AVSs).

• Skin in the Game: Slashing is the ultimate reputation burn.
• Capital Efficiency: High-reputation operators can secure more value with the same stake.

This is the endgame. A wallet with 2 years of consistent Uniswap LP fees, Aave repayments, and Gitcoin donations gets a 200 ETH credit line at 5% APR.

• Dynamic Pricing: Rates adjust in real-time based on wallet activity.
• Automated Recovery: Default triggers automatic social or legal recourse encoded in a smart contract.

Full transparency kills adoption. The next layer is ZK-Reputation. Prove you have a score above X without revealing your entire history.

• Selective Disclosure: Use zkSNARKs (via Aztec, zkSync) to prove creditworthiness to a lender and nothing else.
• Regulatory Bridge: Enables compliance (e.g., accredited investor proof) without doxxing.

This primitive requires a new infrastructure layer. Chainlink oracles fetch off-chain credit data. The Graph indexes complex on-chain behavior. Arweave stores immutable reputation attestations.

• Composability Layer: Scores are queried like any other on-chain asset.
• Anti-Sybil Core: Worldcoin, BrightID provide the foundational human-bound identity.

Without a cost to create identities, any reputation system is instantly gameable. Current solutions like proof-of-humanity or Gitcoin Passport rely on centralized attestations or social graphs, creating a single point of failure.

• Attack Vector: Low-cost identity forgery floods systems with false reputation.
• Dependency Risk: Reliance on off-chain oracles for Sybil resistance.

Reputation scores fed by oracles (e.g., EigenLayer AVS, Chainlink) become a vector for manipulation. A corrupted or bribed oracle can mint unlimited reputation, breaking the system's trust model.

• Centralization Pressure: High-value systems incentivize targeting few oracle nodes.
• Cascading Failure: A single compromised oracle can poison multiple reputation markets (DeFi, governance).

Reputation has value only if it grants access to valuable opportunities (e.g., under-collateralized loans, priority queue access). If the primary use-case fails, reputation value collapses, killing the system.

• Bootstrapping Challenge: Requires simultaneous adoption by lenders and borrowers.
• Network Effect Hurdle: Must outcompete entrenched collateral-based models like MakerDAO or Aave.

Building a persistent, portable reputation graph creates a permanent on-chain identity. This invites regulatory scrutiny (KYC/AML) and destroys the pseudonymous ethos of crypto, potentially killing adoption.

• Data Liability: Protocol becomes custodian of sensitive user graphs.
• Jurisdictional Risk: Must comply with conflicting global data laws (GDPR, etc.).

When reputation is a composable primitive, a bug in one protocol (e.g., EigenLayer slashing) can incorrectly slash reputation scores, causing unjust liquidations across all integrated DeFi apps in a cross-contagion event.

• Systemic Risk: Fault is not contained; it propagates.
• Unintended Consequences: Complex integrations create unmodeled failure modes.

The entity controlling the reputation scoring rules (e.g., a DAO) becomes the de facto central bank of trust. This power is a high-value target for capture by whales or state actors, enabling censorship.

• Power Concentration: Control over scoring = control over economic access.
• Censorship Risk: Can blacklist addresses by setting reputation to zero.

DeFi's reliance on pure financial collateral locks up $50B+ in idle capital and excludes users with assets but no crypto. This creates massive inefficiency and limits the total addressable market for lending and leverage.

• Capital Inefficiency: LTV ratios rarely exceed 80%.
• Exclusionary: No path for users with strong off-chain financials.

Protocols like EigenLayer, Karpatkey, and Obol are turning staking and delegation history into a verifiable, portable reputation score. This creates a new asset class: social collateral.

• Portable Identity: Reputation scores move with the user across dApps.
• Sybil-Resistant: Built on provable, on-chain work history (e.g., running nodes).

Imagine a lending pool that uses a user's EigenLayer operator score or Gitcoin Passport to offer credit lines. This is the bridge to real-world adoption.

• Risk-Based Pricing: Interest rates dynamically adjust based on reputation.
• Default Enforcement: Slashing mechanisms or social recovery replace liquidations.

This requires new primitives. Ethereum Attestation Service (EAS), Verax, and CyberConnect are building the rails to issue, store, and aggregate trust signals from on- and off-chain sources.

• Composable Data: Reputation is a sum of attestations.
• Sovereign Identity: Users own and permission their data.

Reputation is subjective. Who defines the rules? Centralized oracles or DAOs become the new credit bureaus, introducing governance risk and potential for manipulation.

• Governance Attack Vector: Reputation scoring logic is a high-value target.
• Black Swan Events: Mass, correlated slashing could collapse systems.

The winning protocol will be the reputation graph that unifies scores from EigenLayer, DAOs, NFT communities, and credit bureaus. Think The Graph for social capital.

• Network Effects: Value accrues to the aggregator, not individual scorers.
• Composability: A single API for any dApp to query trust.
