Parameter Governance

The primary mechanism for enacting changes, where governance token holders submit and vote on proposals. Votes are weighted by token holdings and recorded immutably on the blockchain. This creates a transparent and auditable record of all parameter adjustments.

• Example: A proposal to adjust the gas fee calculation algorithm on an L2.
• Key Property: Execution is permissionless and automated upon approval.

Governable parameters are precisely defined variables within the protocol's smart contracts. They range from high-impact economic levers to fine-tuned system constants.

• Economic Parameters: Block rewards, staking yields, transaction fees, and slashing penalties.
• Operational Parameters: Block size/gas limits, validator set size, and epoch duration.
• Security Parameters: Finality thresholds, unbonding periods, and governance voting deadlines.

A structured process from ideation to execution, designed to prevent rash changes and ensure sufficient deliberation.

1. Temperature Check: Informal discussion to gauge community sentiment.
2. Formal Proposal Submission: Requires a proposal deposit to prevent spam.
3. Voting Period: A fixed window for token holders to cast votes (For, Against, Abstain).
4. Timelock & Execution: Approved proposals often enter a timelock delay before automatic execution, providing a final safety window.

Systems that allow token holders to delegate their voting power to experts or entities, creating a representative democracy. This addresses voter apathy and concentrates expertise.

• Delegates (or Validators) vote on behalf of their delegators.
• Governance Modules like Compound's Governor Bravo or OpenZeppelin's Governor standardize this functionality.
• Snapshot is often used for off-chain, gas-free sentiment voting that informs on-chain actions.

Protocols include safeguards to respond to critical bugs or exploits when standard governance timelines are too slow.

• Guardian/Pause Multisig: A trusted, multi-signature wallet that can temporarily halt specific system functions.
• Security Council: A designated, elected group with elevated permissions for emergency response.
• These are considered a necessary centralization trade-off, with active governance working to minimize their scope and power over time.

Advanced governance systems incorporate tools to model the effects of parameter changes before they are enacted, reducing risk.

• Testnet Forks: Proposals are deployed on a mirrored testnet to observe behavior.
• Economic Modeling: Tools simulate the impact on tokenomics, validator revenue, and user costs.
• Frameworks like Tally and Boardroom provide interfaces that aggregate proposal data and voter history for informed decision-making.

The primary security risk in parameter governance is the potential for malicious actors to manipulate the decision-making process. Key vectors include:

• Vote Buying: Accumulating enough governance tokens to force through harmful proposals.
• Timelock Exploitation: Bypassing or shortening the delay between a vote's approval and its execution.
• Parameter Tuning Attacks: Deliberately setting parameters (e.g., low collateral ratios) to destabilize the system for profit. Effective governance mitigates these through multi-sig requirements, veto powers, and robust proposal frameworks.

Governance models exist on a spectrum, each with distinct risk profiles:

• Admin Keys / Multi-sig: A small group holds upgrade authority. Risk: Single point of failure if keys are compromised.
• Token-based Voting: Token holders vote on changes. Risk: Low voter turnout can lead to manipulation by whales.
• Futarchy / Prediction Markets: Uses market signals to decide. Risk: Complexity and potential market manipulation. The trade-off is often between security (decentralization) and agility (centralized control in emergencies).

A timelock is a mandatory delay between a governance vote's approval and the execution of the resulting code. This is a non-negotiable security feature because it:

• Provides a final review period for the community to audit the executed code.
• Allows users to exit the system if they disagree with the passed change.
• Prevents instant, malicious upgrades that could drain funds. Protocols like Compound and Uniswap enforce timelocks of several days on all governance-controlled contracts.

Many critical parameters depend on external data feeds (oracles). Incorrect settings or oracle manipulation can cause systemic failure.

• Collateral Factor: Set too high, it risks undercollateralized loans during volatility.
• Liquidation Incentive: Set too low, liquidators won't act; too high, it unfairly penalizes users.
• Interest Rate Models: Poorly calibrated models can lead to insolvency or capital flight. Governance must understand the mathematical relationships between parameters and their oracle dependencies.

Protocols often embed emergency mechanisms to respond to critical threats faster than standard governance allows. These introduce their own risks:

• Pause Guardian: A trusted entity (often multi-sig) can halt specific functions. Risk: Overuse or malicious use censors the protocol.
• Security Council: A designated group with accelerated upgrade powers during emergencies. Risk: Effectively creates a centralized backdoor.
• Circuit Breakers: Automatic triggers (e.g., freezing markets if oracle deviates >20%). Risk: False positives can lock user funds. Transparency and clear invocation criteria are essential for these powers.

Secure parameter governance frameworks implement several defensive layers:

• Progressive Decentralization: Launch with admin control, then gradually transfer powers to token holders.
• Separation of Powers: Critical parameters (e.g., treasury funds) require a higher voting quorum or longer timelock.
• Simulation & Testing: All parameter changes should be simulated on testnets and via tools like Gauntlet or Chaos Labs before mainnet votes.
• Transparent Communication: All proposals must include a detailed risk assessment and technical specification for community review.
