ZIP-0016: ZOO Token Economics

Abstract

This proposal defines the economic model for the ZOO token, including initial distribution, inflation schedule, vesting periods, and the mandatory conservation allocation mechanism. ZOO serves as the native gas and governance token of Zoo Network (L2 on Lux Network) with a fixed initial supply of 1,000,000,000 (1B) tokens and a capped annual inflation rate that decreases over time.

Motivation

A clearly defined token economic model is essential for:

Sustainability: Ensuring long-term funding for conservation initiatives without relying solely on donations
Alignment: Binding protocol economics to the conservation mission of Zoo Labs Foundation (501c3)
Transparency: Providing donors, researchers, and participants with predictable economic guarantees
Ecosystem growth: Incentivizing early contributors while preventing excessive dilution
Regulatory clarity: Maintaining utility-token classification by tying value to governance and network access rather than profit expectations

Specification

Initial Token Distribution

Allocation	Percentage	Amount	Vesting
Conservation Fund	25%	250,000,000	10-year linear unlock
Ecosystem Grants	20%	200,000,000	4-year linear, 1-year cliff
Community Airdrop (ZIP-0002)	10%	100,000,000	Immediate
Foundation Reserve	15%	150,000,000	5-year linear, 1-year cliff
Research Incentives	15%	150,000,000	4-year linear
Liquidity Provision	10%	100,000,000	2-year linear
Core Contributors	5%	50,000,000	4-year linear, 1-year cliff

Inflation Schedule

Annual inflation is capped and decreases on a fixed schedule:

inflation:
  year_1: 5.0%    # Bootstrap ecosystem incentives
  year_2: 4.0%
  year_3: 3.0%
  year_4: 2.5%
  year_5_plus: 2.0%  # Terminal rate
  distribution:
    conservation_fund: 40%  # Of new emissions
    staking_rewards: 35%
    ecosystem_grants: 25%

Conservation Allocation Contract

// SPDX-License-Identifier: MIT
pragma solidity ^0.8.20;

contract ConservationAllocation {
    uint256 public constant CONSERVATION_BPS = 4000; // 40% of emissions
    address public conservationMultisig;
    address public emissionsController;

    event ConservationFunded(uint256 amount, uint256 epoch);

    function distributeEmissions(uint256 totalEmissions) external {
        require(msg.sender == emissionsController, "unauthorized");
        uint256 conservationShare = (totalEmissions * CONSERVATION_BPS) / 10_000;
        IZOO(zooToken).transfer(conservationMultisig, conservationShare);
        emit ConservationFunded(conservationShare, block.timestamp);
    }
}

Burn Mechanism

A portion of transaction fees is burned to counteract inflation:

Base fee burn: 50% of EIP-1559 base fees are burned permanently
Net inflation = Gross emissions - Burned fees
Target: Net inflation approaches 0% as network activity grows

Token Utility

Use Case	Mechanism
Gas fees	Native token for Zoo L2 transactions
Governance	Voting weight on ZIP proposals (1 token = 1 vote)
Staking	Delegate to validators for rewards
Grant funding	Stake to back community grant proposals
Data access	Pay for premium biodiversity data queries

Rationale

The 25% conservation allocation at genesis plus 40% of ongoing emissions ensures the network's primary mission is funded regardless of external donation volume. The decreasing inflation schedule prevents excessive dilution while maintaining incentive budgets during the critical growth phase. Terminal 2% inflation ensures perpetual funding for conservation without supply shocks.

The burn mechanism creates a natural equilibrium: as the network becomes more useful, more fees are burned, offsetting inflation and rewarding long-term holders who are aligned with the conservation mission.

Security Considerations

Vesting contracts must be audited and use timelocks to prevent premature access
Conservation multisig requires 3-of-5 signers including at least one independent board member
Inflation controller is governed by a timelock with 7-day delay for parameter changes
Emergency pause can halt emissions if a critical vulnerability is discovered
Token distribution contract should be deployed behind a proxy with a 48-hour upgrade delay
