The Future of Attribution in a Multi-Wallet, Multi-Chain Ecosystem

EAS is not an identity protocol; it's a decentralized registry for any statement. Its power is in off-chain schemas, enabling custom attestations for DAO membership, credit scores, or KYC proofs without on-chain bloat.\n- Permissionless Schemas: Any entity (e.g., Optimism, Gitcoin) can define and issue attestations.\n- Portable Verifiability: Attestations are cryptographically signed, enabling trustless verification across dApps.

Worldcoin's core innovation is biometric proof of unique humanness, creating a global privacy-preserving identity layer. It solves the fundamental attribution problem of distinguishing one user from a million bots.\n- Zero-Knowledge Proofs: Users prove uniqueness without revealing biometric data.\n- Cross-Application Graph: A single proof can be reused across DeFi, governance (like Aave), and airdrops, collapsing user acquisition costs.

Lens reframes identity as a user-owned social graph. Your followers, posts, and interactions are composable NFTs that travel with you, making social capital a verifiable on-chain asset.\n- Composable Reputation: DApps can query the graph to gauge influence or trust, enabling under-collateralized lending or curated access.\n- Native Monetization: Identity is directly tied to creator economies, flipping the Web2 platform-owned model.

Passport tackles the cold-start problem for reputation by aggregating stamps from both worlds (e.g., BrightID, POAP, Twitter, Github). It uses a scoring mechanism to compute a trust score without a central authority.\n- Plural Identity: Resilience comes from multiple attestations, not one silver bullet.\n- Defense-in-Depth: Actively used by Gitcoin Grants and protocols like Uniswap for sybil-resistant quadratic funding and governance.

No single chain holds a user's complete history. True cross-chain reputation requires secure, trust-minimized state attestation between ecosystems.\n- The Oracle Problem: Bridging reputation requires oracles like Chainlink or light clients to attest to off-chain state, introducing new trust assumptions.\n- Fragmented Liquidity: A user's DeFi history on Arbitrum is invisible to a lender on Base, creating systemic inefficiency.

Account Abstraction shifts identity from key pairs to smart contract wallets. This enables transaction-level attestations, social recovery, and sponsored gas—fundamentally changing how users are identified and onboarded.\n- Session Keys: Users can grant temporary, scoped authority to dApps (e.g., a gaming session), creating a richer interaction graph.\n- Bundler & Paymaster Graphs: Stackup or Biconomy infrastructure creates new data layers for analyzing user intent and reliability.

Tracking a single address is futile. Users have multiple wallets (e.g., MetaMask, Rabby, Phantom) and use intent-based solvers (e.g., UniswapX, CowSwap) that abstract the user. You're missing >80% of the journey.

• Key Benefit 1: Acknowledges the reality of fragmented user identity.
• Key Benefit 2: Forces a shift from address-based to behavior-based analytics.

A shared, open graph that links pseudonymous identities across wallets and chains via behavioral fingerprints and zero-knowledge proofs. Think EigenLayer AVS for attribution.

• Key Benefit 1: Enables cross-DApp, cross-chain loyalty and rewards programs.
• Key Benefit 2: Creates a new data primitive for underwriting and on-chain credit.

The winning protocol will be infrastructure, not an analytics dashboard. It will offer a standardized SDK (like Segment for web3) and monetize via micro-transactions for graph queries and attestations.

• Key Benefit 1: Captures value from all builders needing attribution, not just one vertical.
• Key Benefit 2: Aligns with the modular stack; integrates with oracles (Chainlink), rollups (Arbitrum, Optimism), and bridges (LayerZero, Across).

Raw transaction graphs are a privacy nightmare and regulatory liability. The only viable solution uses zero-knowledge proofs to attest to behavior (e.g., "user bridged >$1k") without revealing the full history.

• Key Benefit 1: Enables compliance-ready analytics (e.g., proof of human, proof of jurisdiction).
• Key Benefit 2: Prevents the system from becoming a surveillance tool, preserving crypto's ethos.

The first major use case is rebuilding digital advertising without platforms. Smart contracts can pay out fees automatically based on proven attribution, enabling trustless affiliate programs and performance-based ad auctions.

• Key Benefit 1: Unlocks $10B+ in ad spend currently inaccessible to on-chain apps.
• Key Benefit 2: Removes intermediaries, driving >50% more value to creators and referrers.

Don't build the graph from scratch. The winning team will deploy an Actively Validated Service (AVS) on EigenLayer, leveraging restaked ETH to secure the attribution graph and bootstrap cryptoeconomic security from day one.

• Key Benefit 1: Instant security with $15B+ in restaked TVL.
• Key Benefit 2: Creates a powerful flywheel: more usage -> more fees -> more operators -> more security.
