ZIP-306: Virtual Sanctuary Governance

Abstract

This proposal defines a DAO governance framework for virtual wildlife sanctuaries within Zoo ecosystem games. A virtual sanctuary is a persistent, player-managed game environment linked to a real-world conservation project. Sanctuary stakeholders (players who hold fractional habitat NFTs per ZIP-203) collectively govern the sanctuary through on-chain proposals and voting: which species to introduce, how to allocate conservation funds, what research priorities to set, and how to respond to in-game ecological events. The framework enforces ecological constraints so that governance decisions must be scientifically plausible, preventing players from making choices that would be ecologically destructive in the real world.

Motivation

Virtual sanctuaries (ZIP-300) are the persistent worlds where conservation games take place. Today, these environments are developer-controlled. Players interact with them but have no say in their management. This misses an opportunity:

Ownership through governance: Players who invest time and funds in a sanctuary should have a voice in its direction. DAO governance transforms passive players into active stewards.
Conservation education: Governing a virtual ecosystem teaches real ecological trade-offs. Introducing a predator affects prey populations; allocating funds to one species diverts from another.
Aligned incentives: When sanctuary governance decisions affect conservation fund allocation (ZIP-301), players who govern well generate more real-world impact.
Community resilience: DAO governance prevents single points of failure. If a game developer abandons a project, the community can continue managing the sanctuary.

Specification

1. Sanctuary DAO Structure

Each virtual sanctuary is governed by a dedicated DAO instance:

contract SanctuaryDAO {
    struct Sanctuary {
        bytes32 sanctuaryId;
        bytes32 habitatId;             // ZIP-300 habitat
        address habitatNft;            // ZIP-203 fractional NFT contract
        uint256 totalShares;
        bytes32 linkedConservationProject;  // Real-world project ID
        bool active;
    }

    struct Proposal {
        uint256 proposalId;
        address proposer;
        ProposalType proposalType;
        bytes data;                    // Encoded proposal details
        uint256 votesFor;
        uint256 votesAgainst;
        uint64 startTime;
        uint64 endTime;
        bool executed;
        bool ecologicallyValid;        // Validated by ecology oracle
    }

    enum ProposalType {
        SPECIES_INTRODUCTION,
        SPECIES_RELOCATION,
        FUND_ALLOCATION,
        RESEARCH_PRIORITY,
        HABITAT_MODIFICATION,
        EMERGENCY_RESPONSE,
        PARAMETER_CHANGE
    }

    // Voting power = fractional NFT shares (ZIP-203)
    function getVotingPower(address voter) public view returns (uint256) {
        return IFractionalHabitatNFT(sanctuary.habitatNft).balanceOf(voter);
    }
}

2. Ecological Validation

All proposals that affect the virtual ecosystem must pass ecological validation before execution:

interface EcologyOracle {
  validateProposal(proposal: Proposal): Promise<EcologyValidation>;
}

interface EcologyValidation {
  valid: boolean;
  ecologicalImpact: {
    biodiversityScore: number;   // -1.0 to +1.0
    carryingCapacity: boolean;   // Within habitat limits?
    trophicBalance: boolean;     // Food web remains stable?
    invasiveRisk: boolean;       // Introduces invasive species?
  };
  reasoning: string;             // Human-readable explanation
  constraints: string[];         // Violated ecological rules
}

The ecology oracle is an AI agent (ZIP-405) that evaluates proposals against established ecological models. Proposals that fail validation (e.g., introducing a species that would collapse the food web) are rejected regardless of vote outcome. Players receive the oracle's reasoning as an educational tool.

3. Governance Parameters

Parameter	Default	Range
Proposal threshold	1% of total shares	0.1% - 5%
Voting period	7 days	3 - 14 days
Quorum	10% of total shares	5% - 25%
Execution delay	48 hours	24 - 72 hours
Emergency quorum	5% of total shares	2% - 10%
Emergency voting period	24 hours	12 - 48 hours

Emergency proposals (fire, disease outbreak, poaching event) use reduced quorum and voting periods to enable rapid response.

4. Fund Allocation Governance

Sanctuary DAOs govern how ZIP-301 conservation funds linked to their habitat are allocated:

interface FundAllocationProposal {
  totalAmount: number;               // ZOO tokens to allocate
  allocations: Allocation[];
  justification: string;
}

interface Allocation {
  recipient: string;                 // Conservation project or research group
  amount: number;
  category: "species_protection" | "habitat_restoration"
           | "research" | "community" | "education";
  milestones: Milestone[];
}

Fund disbursement follows milestone-based release: funds are held in escrow and released as conservation projects report verified progress (ZIP-501).

5. Delegation

Stakeholders may delegate their voting power to conservation experts:

function delegate(address delegatee) external {
    require(balanceOf(msg.sender) > 0, "No shares");
    delegates[msg.sender] = delegatee;
    emit Delegated(msg.sender, delegatee, getVotingPower(msg.sender));
}

Delegation is revocable at any time. Delegatees cannot re-delegate.

Rationale

Fractional NFT voting power: Using ZIP-203 habitat NFT shares as voting weight aligns governance power with economic stake in the sanctuary. Players who invest more have proportionally more say.
Ecological oracle veto: Unrestricted governance could lead to ecologically nonsensical decisions (e.g., introducing polar bears into a tropical reef). The oracle acts as a scientific guardrail while educating players about why certain decisions are harmful.
Emergency governance: Ecological crises require rapid response. Reduced quorum and voting periods for emergency proposals prevent governance paralysis during time-sensitive events.
Milestone-based fund release: Prevents misallocation by requiring verified progress before releasing funds. Aligns with ZIP-501 conservation impact measurement.

Security Considerations

Governance capture: A whale could acquire a majority of fractional NFTs and control the DAO. Mitigation: quadratic voting option (proposal parameter) reduces the power of large holders; maximum voting cap of 10% of total shares per address.
Oracle manipulation: If the ecology oracle is compromised, it could approve harmful proposals. Mitigation: the oracle is an ensemble of independently-run AI agents; a majority must agree for validation. Oracle responses are logged on-chain for audit.
Proposal spam: An attacker could flood the DAO with proposals to cause voter fatigue. Mitigation: proposal threshold (1% of shares) creates an economic cost; proposers forfeit a small deposit if their proposal fails to reach quorum.
Flash-loan governance: An attacker could borrow NFT shares to vote and return them in the same block. Mitigation: voting power snapshots are taken at proposal creation time; shares acquired after snapshot carry no voting weight.
Fund misappropriation: DAO-approved fund recipients could fail to deliver. Mitigation: milestone-based release and DAO ability to halt disbursement via emergency proposal.
