How to Implement Conviction Voting for Continuous Green Funding

Conviction voting is a quadratic funding mechanism designed for continuous, community-driven resource allocation. Unlike traditional one-time votes, it allows participants to signal support for proposals by staking tokens over time. A member's "conviction" in a proposal accumulates based on the amount and duration of their stake, creating a time-weighted voting power. This model is particularly effective for green initiatives like reforestation, renewable energy projects, or conservation efforts, as it enables sustained funding for long-term goals rather than single disbursements. The system continuously tallies these convictions, and once a proposal reaches a dynamically calculated threshold, funds are automatically released from a shared treasury.

To implement a basic conviction voting system, you need a smart contract with core functions for staking, conviction accumulation, and proposal execution. The key data structures track each proposal's total staked amount, the conviction score, and a history of staking events per user. The conviction for a user's stake is not static; it grows over time using a formula, often an exponential decay function, to simulate increasing commitment. A common approach is conviction = stake * (1 - e^(-k * time)), where k is a growth constant. This ensures early supporters have more influence, and withdrawing support resets the accumulated conviction.

Here is a simplified Solidity code snippet illustrating the staking and conviction update logic for a single proposal:

solidityCopy
// Pseudocode for core conviction mechanics
mapping(address => uint256) public stakeAmount;
mapping(address => uint256) public stakeTime;
uint256 public totalConviction;

function stakeToProposal(uint256 _amount) external {
    // Update conviction from existing stake before new action
    _updateConviction(msg.sender);
    
    // Transfer tokens and record new stake
    token.transferFrom(msg.sender, address(this), _amount);
    stakeAmount[msg.sender] += _amount;
    stakeTime[msg.sender] = block.timestamp;
}

function _updateConviction(address _staker) internal {
    uint256 staked = stakeAmount[_staker];
    if (staked == 0) return;
    
    uint256 timeStaked = block.timestamp - stakeTime[_staker];
    // Simplified conviction growth calculation
    uint256 newConviction = staked * timeStaked / 1 days;
    
    // Update global total
    totalConviction = totalConviction + newConviction - oldConviction[_staker];
    oldConviction[_staker] = newConviction;
}

Integrating this system requires a funding pool (like a DAO treasury) and a proposal factory. Each green project submits a proposal detailing its goal, requested budget, and recipient address. The funding threshold is not fixed; it is often calculated as a percentage of the total treasury or based on the sum of all convictions, making it harder to pass proposals as more funds are allocated. This creates a natural prioritization. For environmental DAOs, proposals can be categorized (e.g., carbon sequestration, biodiversity, clean tech), allowing the community to shape a portfolio of funded projects. Platforms like 1Hive's Gardens or Colony provide open-source frameworks to build upon.

Successful deployment demands careful parameter tuning. The conviction growth rate (k), proposal expiration timers, and threshold function directly impact how quickly projects get funded and how the treasury is depleted. A fast growth rate favors rapid consensus but may lead to impulsive funding. A slow rate encourages long-term deliberation, ideal for multi-year ecological projects. Furthermore, you must implement safeguards: a withdrawal delay (e.g., 7 days) to prevent flash loan attacks, and a proposal spam filter (like a minimal stake to submit). Real-world examples include Gitcoin Grants using a similar quadratic funding model for public goods and Commons Stack pioneering conviction voting for community currencies.

For green initiatives, this model aligns incentives with sustained impact. Donors become long-term stakeholders, and projects receive predictable, recurring funding streams conditional on ongoing community support. The next steps are to deploy the contracts on a low-carbon blockchain like Polygon or Gnosis Chain, create a front-end dApp for stakeholder interaction, and establish clear proposal guidelines for environmental verification (e.g., requiring proof of impact from IoT sensors or satellite data). By automating decentralized governance, conviction voting creates a resilient funding mechanism for the planet's most pressing challenges.

Before writing any code, you need a foundational understanding of the core components. Conviction voting is a quadratic signaling mechanism where voting power accrues over time a participant holds their tokens in a proposal's support pool. This creates a continuous funding model, as opposed to one-time grants. You should be familiar with token-weighted governance, smart contract development (Solidity), and have a basic grasp of bonding curves and decentralized autonomous organizations (DAOs). The primary reference implementation is the Commons Stack's Conviction Voting app, built for the 1Hive ecosystem.

Your development environment must be configured to interact with blockchain networks. Essential tools include Node.js (v18+), npm or yarn, and a code editor like VS Code. You will need the Hardhat or Foundry framework for smart contract development and testing. For frontend integration, the conviction voting system typically interfaces with a DAO framework; experience with Aragon OSx or a similar governance SDK is highly beneficial. Ensure you have a wallet like MetaMask installed and testnet ETH (e.g., on Sepolia or Goerli) for deployments.

The system architecture revolves around several key smart contracts. The core is the ConvictionVoting contract, which manages proposal stakes and calculates conviction. It interacts with a TokenManager for the governance token (often a Super Token via Superfluid for streaming) and a Vault or Finance module to hold funds. Proposals are usually managed by an external Agreement or voting app. You must decide on initial parameters: the decay rate (e.g., 90% per week), max ratio (maximum % of funds a proposal can request), and minimum conviction threshold. These parameters significantly impact the system's responsiveness and security.

Start by forking or examining the reference repository. Clone the 1Hive conviction voting repo and install dependencies with npm install. Study the ConvictionVoting.sol contract to understand the _calculateConviction function and the alpha decay parameter. The frontend client, often built with React and apollo-client for querying a subgraph, provides the UI for staking and proposing. Set up a local blockchain network using Hardhat (npx hardhat node) to deploy and test the contracts before proceeding to a testnet.

For a complete system, you must deploy and index the subgraph. The subgraph (using The Graph) is crucial for efficiently querying proposal stakes, conviction scores, and history. After deploying your contracts, you will need to create and deploy a subgraph by defining the schema and mapping scripts in AssemblyScript. This allows your frontend to fetch real-time conviction data. Finally, integrate the voting UI with your DAO's existing frontend, connecting wallet providers and ensuring proper contract addresses are configured for your chosen network (e.g., Gnosis Chain, Polygon).

Conviction voting is a continuous approval voting system where a voter's influence grows over time as they maintain their support for a proposal. Unlike one-time snapshot voting, it uses a time-weighted preference accumulation model. A voter's conviction for a proposal increases asymptotically toward a maximum as they keep their tokens staked on it, simulating a gradual commitment. The total funding allocated to a proposal at any moment is determined by the aggregate conviction staked on it relative to a global threshold and the available communal budget. This creates a demand-driven funding faucet where popular proposals receive a continuous stream of resources without requiring discrete voting rounds.

The core mathematical model is defined by several key formulas. The conviction C_i(t) for voter i on a proposal at time t is calculated using a decay function: C_i(t) = α * C_i(t-1) + s_i(t), where s_i(t) is the newly staked tokens and α (alpha) is a decay factor between 0 and 1 (e.g., 0.9). This creates an exponential moving average of support. The total conviction for a proposal is the sum of all individual convictions. A proposal passes a funding threshold when its total conviction exceeds a dynamically calculated threshold function, often defined as threshold = (total_supply * required_share) / (1 + decay_rate * time_since_last_funded). This function makes it easier to fund a diverse set of proposals over time.

Implementing this model in a smart contract requires tracking several state variables per proposal and voter. Essential storage includes: a mapping of voter address -> proposal ID -> staked amount, a record of each proposal's totalConviction and lastUpdate timestamp, and the global alpha decay parameter. The contract must have a function to calculate conviction at the current block timestamp using the decay formula. A critical optimization is to avoid recalculating conviction from scratch for every interaction by using a last-update checkpoint system, updating the conviction state only when a user stakes, unstakes, or when a proposal is checked for funding eligibility.

A basic staking function in Solidity would update the conviction state before applying a new action. Here is a simplified core logic snippet:

solidityCopy
function _updateConviction(address voter, uint proposalId) internal {
    Proposal storage p = proposals[proposalId];
    uint timeElapsed = block.timestamp - p.lastUpdate;
    // Apply decay to the proposal's total conviction
    p.totalConviction = p.totalConviction * (alpha ** timeElapsed);
    p.lastUpdate = block.timestamp;
}
function stake(uint proposalId, uint amount) external {
    _updateConviction(msg.sender, proposalId);
    // Transfer tokens from user and update individual stake
    ...
    // Recalculate user's new conviction contribution and add to proposal total
    proposals[proposalId].totalConviction += amount;
}

This ensures the conviction model is applied consistently across all state changes.

To manage continuous funding, you need a funding disbursement trigger. This is typically an external call or a periodic function that checks if any proposal's totalConviction exceeds the dynamic threshold. When triggered, the contract executes the funding—transferring tokens from a communal treasury to the proposal's recipient—and then resets that proposal's conviction to zero. This reset is crucial as it represents the satisfied demand, allowing conviction to build anew for the next funding cycle or for other proposals. The threshold function should be designed to prevent a single proposal from monopolizing funds, often by increasing the threshold for a proposal immediately after it is funded.

For a green funding DAO, this model is particularly effective. Proposals for verified carbon offset purchases, renewable energy project grants, or open-source climate research can receive sustained funding as long as the community maintains conviction. Implementation platforms like Aragon OSx with custom voting plugins or DAOHaus via Moloch v3 extensions provide frameworks to build upon. Key considerations for production include: gas optimization for frequent conviction updates, secure oracle integration for threshold parameter updates, and a clear UI that visualizes conviction growth and threshold levels for voters, making the abstract model tangible and actionable for community governance.

Conviction voting is a novel governance mechanism for continuous funding, distinct from traditional one-time snapshot votes. Instead of allocating a fixed budget periodically, it allows community members to signal their continuous support for proposals by staking tokens. A voter's influence, or 'conviction', grows over time their tokens remain committed to a proposal, simulating a gradual consensus-building process. This system is particularly effective for public goods funding and green initiatives, where long-term, sustained investment is more valuable than sporadic lump-sum grants. The core smart contract architecture manages this time-weighted voting logic and the continuous stream of funding.

The system's state is managed by a primary ConvictionVoting contract. Key data structures include a mapping of proposals to their total staked amounts and a mapping of each voter's stake per proposal with a timestamp. The conviction for a voter is calculated using a decay function, often an exponential decay like conviction = stake * (1 - decay_rate) ^ time_elapsed. This ensures older stakes have diminishing influence unless actively maintained. Proposals can be funded once the total conviction crosses a dynamic threshold, often based on the total funds available in a shared funding pool. This creates a market-like mechanism where proposals compete for a continuous stream of capital.

Implementing the stake and conviction logic requires careful handling of time. Use a discrete epoch-based system or block.number for timekeeping to avoid gas-intensive real-time calculations. When a user calls stake(proposalId, amount), the contract must first calculate the decayed conviction from their existing stake, add the new amount, and record the current time. A common optimization is to store a lastUpdated timestamp and a stakeWithDecay value that represents the stake's decayed amount at the last update, recalculating lazily on interaction. The total conviction for a proposal is the sum of all voters' decayed stakes, which must be efficiently aggregated, often requiring an on-chain or oracle-updated tally.

Funding execution is triggered by a executeFunding(proposalId) function. This function checks if the proposal's total conviction exceeds the required threshold, which can be a function of the total pool size (e.g., threshold = total_pool * alpha / total_conviction_supply). If passed, the contract transfers the allocated funds—often a portion of the available pool per epoch—to the proposal's beneficiary address. After execution, the stakes supporting that proposal should be released back to voters, as their conviction has been 'spent'. It's critical to implement robust reentrancy guards and access controls on this function, as it handles direct fund transfers.

A complete architecture includes peripheral contracts for proposal submission, parameter management, and dispute resolution. Proposals should be registered through a proposal factory that enforces criteria (e.g., metadata, beneficiary address). System parameters like the decay rate, funding threshold formula (alpha), and minimum stake duration are typically controlled by a separate governance module (like OpenZeppelin's Governor). For security, consider integrating a hats-like dispute system where a curated group can veto malicious proposals before funding. All contracts should be written in Solidity 0.8.x, use libraries like Solmate for gas efficiency, and be thoroughly tested with forked mainnet simulations.

To deploy, start with a testnet implementation using a token like DAI or WETH on Goerli or Sepolia. Key integration points include connecting to a token vault (e.g., Superfluid for streaming) for the funding pool and a frontend client that visualizes conviction growth. For production, audit the mathematical logic for rounding errors and the incentive compatibility of the threshold mechanism. Reference implementations include 1Hive's Conviction Voting app for Aragon and Commons Stack's Conviction Voting module. This architecture creates a resilient, community-driven funding pipeline ideal for sustaining long-term green projects.

Conviction voting is a novel governance mechanism that moves beyond simple one-person-one-vote models. Instead of a single snapshot, it measures the staked support for a proposal over time. A voter's influence grows the longer they stake their tokens on a proposal, simulating a "conviction" that the proposal is worthwhile. This creates a continuous funding process where proposals can be funded as soon as they accumulate enough sustained support, without requiring discrete voting periods or manual execution.

The core calculation determines a proposal's conviction score at any given moment. The formula models conviction as a logistic growth function, where score growth accelerates as it approaches a predefined spending limit. The base formula is often expressed as: yᵗ = x * βᵗ + yᵗ⁻¹ * δᵗ, where yᵗ is the current conviction, x is the amount of tokens staked, β is a decay factor for older stakes, and δ is a decay factor for the existing conviction. This creates a system where recent, sustained support has the most weight.

Implementing this requires tracking two key state variables per proposal: the total staked tokens and the accumulated conviction. When a user stakes, the new stake amount is added to the total. The conviction is then recalculated, applying decay to the previous conviction and adding the contribution from the new stake. A common simplification, as used by 1Hive's Gardens, uses a half-life decay model where conviction decays exponentially over time when not reinforced by new stakes.

Here is a conceptual JavaScript snippet for updating conviction in a discrete-time model (e.g., per block):

javascriptCopy
function updateConviction(previousConviction, newStake, decayFactor) {
  // Apply decay to previous conviction
  let decayedConviction = previousConviction * decayFactor;
  // Add new stake (which starts with full weight)
  let newConviction = decayedConviction + newStake;
  return newConviction;
}

In a real on-chain implementation, decayFactor is calculated based on time elapsed since the last update, often using a half-life formula: decayFactor = 0.5 ^ (timeElapsed / halfLifePeriod).

The proposal's conviction score is then compared against a dynamic threshold required for passage. This threshold is typically a function of the total funds requested and the available treasury balance, often following an alpha bonding curve. This means the required conviction increases with the requested amount, preventing a single large proposal from draining the treasury. When a proposal's conviction score exceeds this threshold, it can be executed, and the funds are streamed to the recipient.

To implement this system, you need a smart contract that manages:

• A mapping of proposals to their stakedTokens and convictionScore.
• A function for users to stakeFor(proposalId, amount) and unstakeFrom(proposalId, amount).
• A periodic (or block-by-block) process to trigger the updateConviction calculation for all active proposals.
• A function to executeProposal(proposalId) that checks if convictionScore > threshold(requestedAmount) and transfers funds. Frameworks like OpenZeppelin provide secure base contracts for token staking and treasury management to build upon.

In a continuous conviction voting system, funding is not a one-time event but a continuous stream activated by successful proposals. The core execution logic typically resides in a smart contract function, often called executeProposal or releaseFunds. This function acts as the on-chain trigger. It validates that a proposal has reached the required conviction threshold and that its allocated funds are still available in the treasury. Only then does it initiate the fund transfer to the beneficiary address specified in the proposal. This automated check-and-execute pattern removes the need for manual intervention by a central party.

The execution function must perform several critical checks to ensure security and correctness. First, it verifies the proposal's state (e.g., Active, Executed, Cancelled). It then calculates the current conviction for the proposal, which is a function of the total supportive stake and the time it has been active. If this value surpasses the predefined threshold, the contract logic proceeds. It also checks that the requested amount does not exceed the treasury's available balance for the funding pool. A failed check at any point should revert the transaction, preventing invalid executions.

A key implementation detail is handling the funding mechanics. For continuous streams, execution might trigger a vesting contract or schedule a series of transactions. For example, a proposal for a 12-month grant might, upon execution, deploy a vesting contract that linearly releases funds to the beneficiary each month. Alternatively, for simpler one-time grants, the execution function performs a direct transfer. Developers must decide whether to transfer the native chain token (e.g., ETH, MATIC) or an ERC-20 token from the treasury, and implement the appropriate safe transfer methods (e.g., using OpenZeppelin's SafeERC20 library).

Here is a simplified Solidity snippet illustrating the core logic of an execution function:

solidityCopy
function executeProposal(uint256 proposalId) external {
    Proposal storage p = proposals[proposalId];
    require(p.status == ProposalStatus.Active, "Proposal not active");
    require(block.timestamp >= p.startTime, "Voting not started");
    
    uint256 currentConviction = calculateConviction(proposalId);
    require(currentConviction >= convictionThreshold, "Threshold not met");
    require(treasury.balance >= p.amount, "Insufficient treasury funds");
    
    p.status = ProposalStatus.Executed;
    treasury.transfer(p.beneficiary, p.amount);
    emit ProposalExecuted(proposalId, p.amount);
}

This function updates the proposal state and transfers funds in a single atomic transaction.

After successful execution, the system must update its internal accounting. The spent funds are deducted from the relevant treasury pool, and the proposal's status is permanently set to Executed to prevent double-spending. The conviction weight that was supporting the proposal is typically released, allowing those tokens to be used to support other proposals. It's crucial to emit clear events (like ProposalExecuted) so that off-chain indexers and user interfaces can track the flow of funds and update their state accordingly, providing transparency to all participants.

For production systems, consider additional safeguards. Implement a timelock between when a proposal meets its threshold and when it can be executed, allowing for a final review period. Use access controls (e.g., OpenZeppelin's Ownable or role-based AccessControl) to restrict the execute function to a trusted module or a decentralized multisig if needed. Finally, thorough testing is essential: simulate scenarios where conviction fluctuates around the threshold, test treasury balance edge cases, and ensure the system behaves correctly when multiple proposals are executed concurrently. Reference implementations can be found in projects like 1Hive's Gardens.

You now have the architectural blueprint for a conviction voting system. The core components include a ConvictionVoting smart contract to manage proposal staking and decay, a Token contract for the governance asset, and a frontend interface for user interaction. The key innovation is using a time-weighted staking mechanism, where a user's voting power increases the longer their tokens are staked on a proposal, modeled by the formula voting_power = stake * (1 - e^{-k * t}). This design prioritizes long-term commitment over snapshot voting, making it ideal for funding public goods and recurring initiatives.

To move from theory to a live deployment, follow these steps. First, deploy your contracts to a testnet like Sepolia or Goerli. Use a framework like Hardhat or Foundry for scripting the deployment and running tests against the conviction math. Second, integrate the smart contract with a frontend library such as wagmi or ethers.js. Your dApp should allow users to connect their wallet, view active proposals, stake/unstake tokens, and see real-time conviction scores. Consider using The Graph to index and query proposal and staking data efficiently for the frontend.

Successful governance requires an active community. Before launching on mainnet, run a pilot program with a trusted group using test tokens. Gather feedback on the UX, proposal submission process, and the clarity of the conviction algorithm. Educate your community on how conviction differs from one-person-one-vote systems—emphasize that impact comes from sustained support. Resources like the Commons Stack's Conviction Voting research and 1Hive's implementation provide valuable community-tested patterns and considerations for parameter tuning (like the k decay factor).

The final step is mainnet deployment and ongoing governance. Choose a launch strategy: will you bootstrap the funding pool with an initial endowment, or use a mechanism like Giveth's Quadratic Funding to seed it? Once live, monitor key metrics: proposal throughput, average staking duration, and the distribution of conviction power. Be prepared to iterate; you may need to adjust proposal thresholds or the decay rate based on real-world usage. The goal is a self-sustaining ecosystem where community conviction continuously allocates resources to its most valued projects.
