The Future of Reputation: Resettable, Not Permanent

Permanent on-chain records like a Soulbound Token (SBT) for a failed hack or a single exploit permanently tarnish an address. This creates a permissionless blacklist, stifles developer experimentation, and prevents legitimate actors from recovering from mistakes.\n- No path to redemption for addresses, even after years of good behavior.\n- Discourages risk-taking and protocol upgrades, as failure is eternal.

Reputation should be a dynamic score that decays over time and is scoped to specific contexts (e.g., DeFi lending vs. NFT curation). A past liquidation doesn't doom you forever; a good track record in one domain doesn't grant undue trust in another.\n- Contextual scoring prevents reputation spillover and sybil attacks.\n- Exponential decay functions ensure old data has less weight, enabling resets.

Current models like Gitcoin Passport or simple token-gating are trivial to game with sybil wallets. Reputation becomes a commodity, not a signal, because creating a new identity costs ~$1 in gas. This undermines the entire premise of trust.\n- Reputation is not scarce, making it worthless as a trust primitive.\n- Leads to governance capture and airdrop farming at scale.

Genuine reputation requires costly-to-fake signals. This means anchoring to Proof-of-Personhood (PoP) systems like Worldcoin or IRL verification, or requiring skin-in-the-game via locked capital or provable work. The cost of creating a new reputable identity must be high.\n- PoP provides a scarce root for the identity graph.\n- Bonding curves for reputation make accumulation expensive and sybil-resistant.

Most "on-chain" reputation relies on off-chain oracles (e.g., Cred Protocol, Spectral) with black-box ML models. This reintroduces central points of failure and manipulation. Users cannot audit or dispute their score, violating crypto's core tenets.\n- Oracle risk replaces smart contract risk.\n- Lack of verifiability makes reputation an opaque credit score 2.0.

The future is decentralized attestation networks like Ethereum Attestation Service (EAS) or Verax. Reputation is a graph of cryptographically signed statements from known issuers, stored on-chain or on IPFS. Anyone can verify the proof and the issuer's reputation.\n- Composable trust graphs built from verifiable claims.\n- User-centric portability of reputation across applications.

Permanent, public transaction histories create two opposing failures. For users, a single mistake or hack is forever. For protocols, the lack of persistent cost makes Sybil attacks trivial, forcing reliance on centralized KYC or VC-backed capital. This breaks the trustless ideal.

• Sybil Resistance: Current models fail without centralized anchors.
• Innovation Tax: Developers avoid novel mechanisms fearing permanent exploit.
• User Risk: A compromised wallet or bad debt becomes a life sentence.

Reputation should be a verifiable, expiring attestation, not a permanent ledger. Systems like Ethereum Attestation Service (EAS) and Verax allow for composable, time-decaying credentials. A user's "credit score" or "DAO contribution" is a snapshot, not a tattoo.

• Controlled Lifespan: Attestations expire, enabling organic reputation decay and resets.
• Composable Privacy: Zero-knowledge proofs (like Sismo, Worldcoin) can verify credentials without exposing underlying data.
• Protocol-Generated Reputation: Uniswap LP history or Aave repayment streaks become portable, temporary attestations.

Vitalik's Soulbound Tokens (SBTs) concept, when paired with smart contract wallets (Safe, Argent), creates a practical reset mechanism. The "Soul" is a long-term identity layer holding recoverable keys. Ephemeral burner wallets perform daily transactions and can be discarded without reputation loss.

• Fault Isolation: A compromised burner wallet burns down, the Soul remains.
• Gradual Trust Decay: SBTs from a DAO lose weight over time unless re-verified.
• Native Account Abstraction: Smart wallets enable social recovery and session keys, making resets a user-initiated feature, not a protocol hack.

Resettable reputation unlocks the holy grail of on-chain credit. Protocols like Cred Protocol and Spectral can issue credit scores based on expiring on-chain history. A default burns the score, not eternal blacklisting. This creates a dynamic risk market instead of today's binary over-collateralization.

• Risk-Based Pricing: Interest rates adjust based on a decaying reputation score.
• Default as Reset: A bad debt clears the slate after a penalty period, enabling rehabilitation.
• Capital Efficiency: Moves beyond the $50B+ locked in over-collateralized DeFi loans.

Proving reputation without exposing history requires ZK oracles. Projects like Polygon ID and zkPass enable users to generate a proof (e.g., "I have >100 Aave repayments") without revealing their address or full timeline. The verification is the attestation; the underlying data stays private and disposable.

• Selective Disclosure: Prove specific reputation facets, not your entire financial life.
• Cross-Chain Portability: A ZK proof of reputation on Arbitrum is verifiable on Base.
• Front-Running Resistance: Reputation proofs are submitted with the transaction, not searched on an open ledger.

Permanent governance power leads to voter apathy and plutocracy. Expiring voting tokens or time-decayed voting credits (like Optimism's Citizen House) tie influence to recent, active participation. Your vote weight resets each season, forcing re-engagement and preventing power consolidation.

• Anti-Entropy: Inactive members' influence automatically decays.
• Sybil-Resistant Participation: Pair with proof-of-personhood for one-vote-per-human seasons.
• Adaptive Quorums: Governance thresholds adjust based on active reputation in the system, not total token supply.
