The Future of Reputation Is Decentralized

Your reputation is locked in Web2 silos like Twitter or GitHub. Zero composability means you rebuild trust from scratch on every new dApp or DAO.

• Sybil resistance is impossible without a persistent identity layer.
• Airdrop farming and governance attacks exploit this fragmentation.

Protocols like Ethereum Attestation Service (EAS) and Verax enable trustless, on-chain statements about any subject. This creates a universal reputation layer.

• Composable Data: A DAO membership attestation can be used for a lending protocol's credit check.
• Sovereignty: Users own and can selectively disclose their attestation graph.

Your proven contributions or credit history are worthless as collateral. DeFi is over-collateralized because it lacks a native trust primitive.

• Undercollateralized lending is a $1T+ market opportunity waiting for on-chain reputation.
• Proof-of-Work for identity is inefficient and excludes non-technical users.

Projects like Spectral and ARCx are building on-chain credit scores using wallet transaction history. This enables programmable trust.

• Soulbound Tokens (SBTs) represent non-transferable achievements for underwriting.
• Modular Risk Engines: DeFi protocols can plug in custom reputation models for risk assessment.

One-token-one-vote leads to whale dominance and vote-buying. Sybil attacks make quadratic voting and other democratic models impossible to implement fairly.

• DAO participation rates are often below 5% due to low-stakes, anonymous voting.

World ID provides global Sybil resistance, while Gitcoin Passport aggregates Web2/Web3 stamps. This enables one-human-one-vote systems and delegated reputation.

• Smart Delegation: Users can delegate voting power based on a delegate's proven expertise (e.g., attested by EAS).
• Context-Specific Reputation: A user's reputation in a DeFi DAO differs from their reputation in an art NFT DAO.

Without a cost to identity creation, any reputation system is meaningless. Proof-of-stake and proof-of-work are insufficient for social graphs.\n- Costless Forks: An attacker can spawn infinite identities to manipulate ratings, as seen in early DAO governance.\n- Collusion Markets: Reputation can be bought, rented, or brigaded, undermining the signal.

Reputation is only as good as its input data. On-chain activity is sparse and off-chain data is unverifiable.\n- Oracle Problem: Importing Twitter followers or GitHub commits requires trusted oracles, reintroducing centralization.\n- Context Collapse: A high score in DeFi lending says nothing about your reliability as a DAO contributor, leading to misuse.

Immutability, blockchain's strength, is reputation's curse. It prevents growth, forgiveness, and creates toxic accountability.\n- No Right to Be Forgotten: A single early mistake is permanently enshrined, violating GDPR and human dignity.\n- Extortion Vector: Negative reputation becomes a permanent blackmail asset, as theorized in "The Schelling Point of Screaming".

For reputation to be a useful asset, it must be portable and composable across applications. Current systems are walled gardens.\n- Protocol Silos: Your Ethereum DeFi score is useless on Solana or in a Farcaster social app.\n- Composability Break: Smart contracts can't natively read and trust external reputation states without introducing new trust assumptions.

Reputation is inherently subjective. Achieving decentralized consensus on a subjective score is a contradiction.\n- Governance Capture: The entity defining the reputation algorithm (e.g., a DAO) becomes a centralized point of control and attack.\n- Forking Identity: Disagreements lead to competing reputation forks, diluting the network effect, as seen in MakerDAO and Curve wars.

To be useful, reputation must be provable; to be private, it must be hidden. Zero-knowledge proofs add immense complexity.\n- ZK Overhead: Generating a ZK proof for a rich reputation history (e.g., "I'm a top 1% dev") requires ~10s+ and high gas costs.\n- Selective Disclosure: Systems like Sismo and Semaphore show promise but remain niche due to UX friction and proof aggregation challenges.

Protocols waste millions on mercenary capital. Current solutions like proof-of-humanity are slow and centralized.

• Solution: Portable, composable reputation graphs from Gitcoin Passport, Worldcoin, or BrightID.
• Benefit: Target real users, not bots. Increase >70% capital efficiency in incentive programs.

DeFi's $50B+ lending market is trapped by over-collateralization. Credit is impossible without a persistent identity layer.

• Build On: Reputation oracles like Spectral Finance or ARCx that score on-chain history.
• Result: Unlock 10-100x larger addressable market for peer-to-peer and institutional credit.

Soulbound Tokens (SBTs) are the atomic unit for non-transferable reputation. They create a persistent, user-owned record.

• Key Use: DAO governance, professional credentials, and Ethereum Attestation Service verifications.
• Architecture: Must be privacy-preserving (e.g., zero-knowledge proofs) to avoid dystopian scoring.

Raw on-chain data is noisy. Specialized oracles are needed to compute and attest reputation scores.

• Players: Spectral (credit), RabbitHole (skills), Galxe (participation).
• Metric: Latency matters. Look for <5 block finality for real-time underwriting.

One-token-one-vote is broken. It enables whale dominance and low-quality participation.

• Mechanism: Conviction Voting, Hats Protocol, or reputation-weighted quorums.
• Outcome: Align voting power with proven contribution, not just capital. Reduce governance attacks by >90%.

A decentralized reputation system that leaks personal data or is controlled by a single entity is worse than useless.

• Mandatory Tech: Zero-Knowledge Proofs (e.g., zkSNARKs) for selective disclosure.
• Design Principle: User custody of data. Avoid the Web2 social credit trap.
