Why Reputation Decays Are More Important Than Rewards

Permanent, farmable reputation creates fake identities for profit, polluting governance and security. Decay introduces a sustained cost of forgery, making attacks economically unviable over time.

• Cost of Attack: Scales with time, not just initial capital.
• Data Integrity: Ensures on-chain reputation reflects real-world behavior.
• Protocol Defense: Critical for Proof-of-Stake security and DAO governance.

Without decay, restaked capital becomes a permanent, low-effort yield source, diluting security guarantees. Decay forces active re-evaluation of operator performance and slashing risk.

• Security Refresh: Operators must continually prove reliability.
• Capital Efficiency: Frees locked capital from underperforming nodes.
• AVS Alignment: Ensures EigenLayer operators are incentivized for long-term health, not just upfront deposits.

Static reputation for data providers (e.g., Chainlink) leads to stagnation and hidden failures. Decay mandates continuous accuracy proofs, creating a market for the most reliable data feeds.

• Data Quality: Poor performance directly impacts reputation score.
• Dynamic Curation: New, better oracles can rapidly gain trust.
• System Resilience: Mitigates systemic risk from a trusted provider going rogue.

Static credit scores in protocols like Aave or Compound fail to capture changing risk profiles. Decaying reputation enables real-time risk assessment, allowing for dynamic loan-to-value ratios and interest rates.

• Default Prediction: Identifies deteriorating borrowers proactively.
• Capital Efficiency: Enables higher leverage for consistently good actors.
• Protocol Safety: Reduces bad debt accumulation during market downturns.

In rollup ecosystems (e.g., Arbitrum, Optimism), permanent sequencer rights create centralization and rent-seeking. Decaying reputation based on liveness and fair ordering enables permissionless, meritocratic rotation.

• Liveness Guarantee: Poor performance loses future rights.
• Fair MEV Distribution: Incentivizes transparent block building.
• Decentralization: Prevents cartel formation among sequencers.

Airdrop farming rewards one-time interaction. Decaying reputation, like Gitcoin Passport's scoring, rewards consistent, valuable participation, aligning users with protocol success.

• Loyalty Over Extraction: Incentivizes recurring use, not hit-and-run.
• Community Signal: Identifies genuine advocates vs. mercenaries.
• Sustainable Growth: Builds a core user base that grows with the network.

Pure reward-for-work attracts low-cost, low-quality actors who spin up thousands of fake identities (Sybils) to farm incentives, diluting network security. This is the fatal flaw of naive staking or simple proof-of-work schemes.

• Sybil resistance is not identity verification; it's about making fake identities economically irrational.
• Systems like Proof-of-Stake and BrightID attempt this, but are still gamed.
• A decaying reputation score attached to a capital stake creates a sunk cost that Sybils cannot afford to burn.

On-chain systems need reliable data feeds (oracles). A static reputation score for oracles is useless—yesterday's accuracy doesn't guarantee tomorrow's. A decay mechanism is a time-weighted moving average of performance.

• Forces continuous performance; a single failure impacts the score for its half-life.
• Protocols like Chainlink and Pyth implicitly use this via staking slashing and committee rotation.
• Decay turns reputation into a velocity metric, not a stagnant balance sheet item.

If reputation is simply a function of capital staked (e.g., TVL), you create a static oligarchy. New, high-quality participants are locked out, and incumbents have no incentive to perform. Decay democratizes access by eroding the score of inactive capital.

• This is the critical innovation over Curve's vote-escrow model, which creates permanent governance lock-in.
• Decay ensures the reputation leaderboard reflects current network contribution, not historical wealth.
• Aligns with Vitalik's "Soulbound Tokens" philosophy—reputation should be earned, not just bought.

In consensus (e.g., Tendermint, Ethereum), validators must balance liveness (producing blocks) with safety (not signing conflicting blocks). A static slashing penalty is a binary, catastrophic punishment. Reputation decay provides a graded, continuous penalty for minor faults.

• A single missed block causes a small reputation burn, not a total stake loss.
• Allows the network to gracefully degrade unreliable nodes instead of ejecting them violently.
• Creates a smoother incentive surface, reducing the risk of correlated failures during turbulence.

For rollups and data availability layers (Celestia, EigenDA), the core service is publishing data. A provider could publish faithfully for a year, then go offline or censor. A decaying reputation score requires continuous proof of liveness and correctness.

• Each successful data post refreshes the decay timer.
• Long-term reliability is measured by the integral under the decay curve, not a binary flag.
• This is superior to simple bonding models used by early Optimistic Rollups.

In protocol governance (Compound, Uniswap), voting power is often token-weighted, allowing whales to dominate. Reputation-weighted voting, with decay, ties influence to recent, proven contribution to the ecosystem.

• A VC's large token grant decays if they don't actively participate in forums, audits, or development.
• Mitigates the voter apathy and low-information voting that plagues DAO governance.
• Aligns with Gitcoin's Grants quadratic funding, which weights many small signals over one large one.
