The Cost of Fragmented Reputation Silos Across Web3

Every new dApp or chain resets user reputation to zero, imposing a ~$100M+ annual cost in Sybil resistance overhead and user acquisition. This fragmentation kills composability and forces protocols like Aave and Compound to duplicate KYC/credit checks.

• Zero-Credit New Users: No history portability from Ethereum to Base or Solana.
• Duplicated Sybil Costs: Each airdrop and grant program pays for redundant attestations.
• Stunted Growth: User loyalty and trust are non-transferable assets.

Decouple reputation from applications using verifiable, on-chain attestation standards like EAS or Verax. This creates a universal social graph where a user's Gitcoin Passport or Optimism Attestation is recognized cross-chain.

• Composable Trust: A single proof-of-humanity unlocks gasless transactions and undercollateralized loans everywhere.
• Protocol-Level Integration: Layer 2s like Arbitrum and zkSync can bake reputation into their state roots.
• Developer Leverage: Builders query a unified graph instead of siloed data.

The rise of intent-based systems (UniswapX, CowSwap, Across) and modular execution layers (EigenLayer, AltLayer) demands a portable reputation layer. Solvers and operators need a global credit score to optimize for efficiency and security.

• Solver Reputation: An Across solver's performance on Ethereum informs its priority on Avalanche.
• Restaking Security: EigenLayer operators carry their slashing history to new AVSs.
• User Intents: A high-reputation user gets better rates and guarantee on any intent-centric DEX.

Chainscore acts as the reputation oracle, aggregating and weighting attestations from Ethereum Mainnet, Layer 2s, and off-chain sources (Discord, GitHub) into a portable score. It's the Chainlink for trust, providing a single query for any protocol's risk engine.

• Multi-Source Aggregation: Synthesizes data from EAS, Worldcoin, and Galxe.
• Cross-Chain Verification: Uses LayerZero and CCIP for state proof delivery.
• Customizable Weights: Protocols tune scores for their specific risk parameters (e.g., DeFi vs. Gaming).

Fragmented reputation is the primary bottleneck for ~$1T+ in latent on-chain credit markets. A portable score enables true undercollateralized lending, moving DeFi beyond overcollateralized stagnation.

• Capital Efficiency: Reduce collateral ratios from 150%+ to 110% for high-score users.
• New Markets: Enable subscription NFTs, rentable assets, and recursive lending.
• Protocol Revenue: Lending platforms like Aave capture fees from currently impossible loan products.

Just as ERC-20 standardized tokens, the next infrastructure wave will standardize reputation. The network effects of a unified system are too powerful; the winning standard will be adopted by major L2 rollups and become a default primitive in the Ethereum execution layer.

• L2 Native Integration: Base, Optimism, and Arbitrum will bake it in for competitive advantage.
• Wallet-Level Feature: Wallets like Rainbow and MetaMask display scores natively.
• Regulatory Clarity: Provides a clear, on-chain alternative to traditional KYC.

Sybil attackers dilute real user rewards by spinning up thousands of wallets, forcing protocols to implement complex, often inaccurate, filtering. This creates a negative-sum game where honest users are penalized and protocol growth is gamed.

• ~$1B+ in airdrop value misallocated annually.
• >50% of Sybil wallets often evade detection.
• Result: Capital inefficiency and eroded community trust.

Without a cross-chain or cross-protocol credit history, lending markets operate on over-collateralization. A user with a $10M repayment history on Aave is treated the same as a new wallet, locking up billions in idle capital.

• ~$30B+ in excess collateral locked across DeFi.
• 0% credit history portability between protocols like Aave, Compound, and Morpho.
• Result: Stifled capital efficiency and user experience.

Governance participation and work contributions are locked within individual DAOs like Uniswap, Optimism, and Arbitrum. This prevents the formation of a verifiable professional reputation, hindering talent discovery and compensation.

• Contributor history is non-composable and non-transferable.
• >70% of active DAO contributors are members of 3+ DAOs, but their impact is siloed.
• Result: Inefficient labor markets and fragmented contributor identity.

Users and integrators cannot assess the historical reliability of cross-chain bridges (e.g., Across, LayerZero) or rollup sequencers. Each interaction is a blind trust exercise, creating systemic risk and hindering adoption.

• $2B+ lost to bridge hacks, yet reliability scores are not standardized.
• Uptime and latency data for sequencers like Arbitrum, Base are not universally attestable.
• Result: Persistent security theater and user anxiety.

A user's offer history and reputation as a fair trader on Blur does not follow them to OpenSea or Magic Eden. This fragments liquidity and forces rebuilds of trust, increasing friction for high-value trades.

• Trader reputation is an off-chain social graph, not an on-chain asset.
• Zero portability of bid/ask reliability across marketplaces.
• Result: Reduced market depth and increased counterparty risk.

The antidote is a sovereign, composable reputation layer built on verifiable credentials and attestations (e.g., EAS, Verax). This creates a persistent, user-controlled graph of trust that protocols can query without lock-in.

• Unlocks under-collateralized lending via portable credit scores.
• Neutralizes Sybil attacks with provable identity graphs.
• Enables cross-protocol loyalty and efficient labor/attention markets.
