Vote Tally

The vote tally is the critical final step that triggers on-chain execution. Once the voting period ends, the smart contract's tallying logic is invoked to:

• Sum the weighted votes for each option.
• Apply the predefined quorum and majority thresholds.
• If the proposal passes, automatically execute the encoded actions, such as transferring treasury funds or upgrading a protocol contract.

Tallying mechanisms differ based on the governance token model. Common systems include:

• Token-weighted: One token equals one vote; the tally sums token amounts.
• Quadratic Voting: Vote power is the square root of tokens committed, tallied to reduce whale dominance.
• Conviction Voting: Votes accumulate weight over time; the tally considers the duration of a voter's stance.
• Delegated: Votes from delegates are automatically tallied on behalf of their delegators.

Vote tallying occurs in two primary environments with different finality guarantees:

• On-Chain Tally: Votes are cast as blockchain transactions. The tally is computed by the protocol's smart contract, is immutable, and can directly execute outcomes. Used by Compound and Uniswap.
• Snapshot Tally: Votes are signed messages stored off-chain. The tally is computed by the Snapshot service, providing a gas-free signal. Execution requires a separate, trusted multisig transaction. This separates sentiment signaling from final execution.

The integrity of the vote tally is paramount. Key considerations and vulnerabilities include:

• Quorum Manipulation: Low participation can be exploited to pass proposals with minimal support.
• Vote Buying/Snapshot Manipulation: Attackers may borrow or acquire tokens temporarily to sway an off-chain tally.
• Timelock & Execution Delay: Many protocols add a delay between tally finalization and execution, allowing time for community review and reaction to a malicious proposal that has passed.

Uniswap's move from V2 to V3 was governed by a token-weighted, on-chain vote. The process demonstrated a full tally lifecycle:

1. A proposal to deploy Uniswap V3 was created.
2. Delegates and token holders cast votes for/against.
3. After the voting period, the Governor Bravo contract tallied the votes, applying a 40 million UNI quorum and majority threshold.
4. The passing tally automatically triggered the deployment of the new protocol contracts via the Timelock.

A core principle of decentralized governance is that any participant can independently verify the tally. This is enabled by:

• Open-Source Tallying Logic: The smart contract code defining the tally rules is publicly auditable.
• Immutable Voting Data: All on-chain votes are permanently recorded on the blockchain.
• Block Explorers & Tools: Services like Tally.xyz and Etherscan provide user-friendly interfaces to view proposal status, live vote counts, and final tally results, ensuring the process is transparent and auditable.

A Sybil attack occurs when a single entity creates many pseudonymous identities to gain disproportionate voting power. Defenses include:

• Token-weighted voting: Voting power is tied to a scarce, costly resource (e.g., governance tokens).
• Proof-of-stake or Proof-of-work: Linking voting rights to economic stake or computational work.
• Identity verification: Using systems like Proof of Personhood (e.g., Worldcoin, BrightID) to ensure one-human-one-vote, though this introduces centralization trade-offs.

The open, on-chain nature of many voting mechanisms makes vote buying and bribery tangible threats. Attackers can offer direct payments to voters for supporting a specific proposal. Countermeasures include:

• Commit-reveal schemes: Votes are submitted as hashes and revealed later, making bribes contingent on an unknown vote.
• Minimal anti-collusion infrastructure (MACI): Uses zero-knowledge proofs to allow a central administrator to detect and nullify votes from colluding parties without revealing individual votes.
• Time-locked voting tokens: Tokens used for voting are locked for a period, increasing the cost of short-term bribery.

Attackers can use flash loans to temporarily borrow massive amounts of governance tokens, vote on a proposal, and repay the loan—all within a single transaction block. This allows manipulation with zero upfront capital. Mitigations include:

• Vote snapshotting: Taking a snapshot of token balances at a predetermined block height well before the voting period, eliminating the impact of transient balances.
• Time-weighted voting: Calculating voting power based on the average token balance over a period, not a single moment.
• Quorum requirements: Setting high quorums makes temporary manipulation more expensive and difficult.

Low voter participation (voter apathy) is a systemic security risk, as it lowers the quorum and makes the system easier to attack or capture by a small, motivated group. Consequences include:

• Proposal hijacking: A well-funded minority can pass proposals against the network's broader interest.
• Reduced legitimacy: Outcomes lack the social consensus needed for smooth execution. Solutions involve delegated voting, incentive programs for participation, and gasless voting mechanisms to reduce participation costs.

In on-chain voting, the order of transactions in a block is controlled by miners or validators, who can front-run or censor votes. An attacker could:

• Pay higher gas fees to ensure their vote is included after seeing others' votes.
• Bribe a validator to exclude opposing votes from a block. Mitigations include using commit-reveal schemes or conducting voting on layer-2 solutions or snapshot platforms that separate vote signaling from on-chain execution.

Analogous to consensus-layer attacks, a governance 51% attack occurs when an entity acquires majority voting power. This allows them to:

• Pass malicious proposals to drain the treasury or mint unlimited tokens.
• Change protocol parameters to benefit themselves (e.g., lowering loan liquidation thresholds).
• Upgrade contracts to introduce backdoors. Defense is primarily economic: making the cost of acquiring a majority stake prohibitively high, or implementing time-locks and multi-sig guardian roles for critical changes as a final backstop.

The minimum threshold of total voting power that must participate for a governance proposal to be considered valid and executable. Quorum prevents a small, unrepresentative group from making binding decisions. For example, a DAO may set a quorum of 20% of its total token supply.

• Purpose: Ensures sufficient voter turnout for legitimacy.
• Failure: If quorum is not met, the proposal fails regardless of the vote distribution.

The weight assigned to a participant's vote, typically derived from their token holdings or delegated stake. Voting power is the fundamental unit counted in a tally.

• Token-weighted: Most common, where 1 token = 1 vote.
• Delegated: Users can delegate their voting power to representatives.
• Quadratic Voting: A mechanism where power increases with the square root of tokens held, designed to reduce whale dominance.

A system where governance proposals and their vote tallies are executed automatically by smart contracts on the blockchain itself. The tally is the definitive state change.

• Examples: Compound's Governor Bravo, Uniswap's governance module.
• Process: Proposal submission, voting period, and execution are all immutable on-chain events.
• Contrast: Differs from off-chain signaling (like Snapshot) which requires separate execution.

The process by which a token holder (delegator) assigns their voting power to another address (delegate) to vote on their behalf. The delegate's votes are tallied with the combined weight of all delegators.

• Purpose: Enables governance participation for less active users and fosters expert delegates.
• Mechanism: Often implemented via ERC-20 token contracts or dedicated governance modules like OpenZeppelin's.

The minimum amount of voting power (e.g., token balance) a user must possess or have delegated to them to submit a governance proposal for a vote. This is a gatekeeping mechanism separate from the vote tally.

• Function: Prevents spam and ensures proposals have a baseline of community support.
• Example: A protocol may require a proposer to hold 0.5% of the total token supply.
