The Future of Banking: Composable Reputation Legos

Your financial identity is locked in centralized bureaus, non-transferable across borders or protocols, and lacks real-time granularity.

• Data Silos: No single view of cross-chain DeFi activity or on-chain income.
• Slow Updates: Monthly reporting cycles vs. real-time blockchain state.
• Zero Composability: Cannot be used as collateral or integrated into smart contracts.

Protocols like Ethereum Attestation Service (EAS) and Verax create standard schemas for issuing, storing, and verifying trust statements on-chain.

• Portable Identity: Attestations are public goods, owned by the user and verifiable by any app.
• Rich Context: Can attest to anything: KYC status, loan repayment history, governance participation.
• Composable Legos: Builds a foundational data layer for credit markets, sybil-resistant airdrops, and undercollateralized lending.

Protocols waste billions in token incentives on fake users and farmers, destroying value and misaligning communities.

• Inefficient Capital: Up to 60-70% of airdropped tokens are immediately sold by farmers.
• Poor Signal: Cannot identify genuine, long-term contributors vs. mercenary capital.

Networks like Gitcoin Passport and Worldcoin aggregate off-chain and on-chain signals to generate a unique, persistent human identity score.

• Programmable Trust: DApps can set minimum score thresholds for access or rewards.
• Multi-Chain: Identity is chain-agnostic, enabling cross-ecosystem reputation.
• Privacy-Preserving: Can use zero-knowledge proofs to verify traits without revealing raw data.

DeFi requires 150%+ overcollateralization, locking up capital and excluding creditworthy borrowers without large crypto holdings.

• Capital Inefficiency: $10B+ in idle collateral that could be redeployed.
• No Underwriting: Pure math-based models ignore income streams or historical behavior.

Protocols like Cred Protocol and Spectral Finance generate on-chain credit scores by analyzing wallet transaction history, enabling risk-based lending.

• Dynamic Risk Pricing: Interest rates adjust based on real-time wallet health and repayment history.
• Cross-Protocol History: Aggregates activity across Aave, Compound, Uniswap to build a holistic profile.
• Native Integration: Smart contracts can permissionlessly check a score before executing a loan.

Composability amplifies the value of a single high-reputation score, creating a massive incentive to forge or steal it. A compromised Gitcoin Passport or World ID credential could be used to drain liquidity across dozens of protocols simultaneously.

• Sybil-for-Hire markets could emerge, offering >90% discount loans via manipulated scores.
• Cross-protocol contamination: A single bad actor could poison the data layer for EigenLayer AVSs or Hyperliquid's intent solver network.

Reputation is only as good as its inputs. Centralized data oracles like Chainlink or Pyth become single points of failure. A cartel of data providers could collude to inflate or suppress scores for profit.

• Flash loan attacks could be used to temporarily distort on-chain behavior metrics that feed reputation models.
• Off-chain data (credit scores, KYC) reintroduces the very custodial risk the system aims to eliminate.

A globally composable reputation system will inevitably clash with jurisdictional boundaries. A score valid for undercollateralized lending on Aave in one region may violate lending laws in another.

• Protocols like Maple Finance or Goldfinch could face enforcement actions for relying on "unapproved" identity lego.
• Forced fragmentation: Regulators may mandate localized, non-composable reputation pools, killing the network effect.

What happens when a previously high-score entity is downgraded? A cascading liquidation across all integrated protocols could create a death spiral, similar to the 2022 leverage unwind but based on social capital.

• Automated slashing in systems like EigenLayer could be triggered en masse by a flawed reputation update.
• No circuit breakers: The composable, permissionless nature makes coordinated emergency pauses impossible.

To build a robust score, you need rich data. To preserve sovereignty, you need privacy. Zero-knowledge proofs (ZKPs) add overhead and complexity; most systems will default to transparent on-chain activity, creating permanent, exploitable behavioral graphs.

• Reputation as a public good conflicts with individual privacy. Your financial history becomes a public NFT.
• ZK-proof generation costs (~$0.01-$0.10 per tx) could price out small users, creating a reputation elite.

Smart contract risk is compounded when legos are stacked. A reputation module from Orange Protocol composed with a lending market from Compound and a prediction market from Polymarket could have emergent failure modes no single audit could catch.

• Complexity > Security: The DeFi summer exploit pattern repeats, but with identity as the root cause.
• Upgrade risks: A "routine" upgrade to one lego (e.g., Ethereum Attestation Service) could break assumptions across the entire stack.
