🎯 FairDrop Protocol

Purpose​

Enables fair and Sybil-resistant distribution in airdrops, NFT minting, and community rewards.

Limitations of Current Distribution Models​

  • Bot-Driven Preemption: Typical airdrops suffer from automated bots claiming the majority of tokens.
  • Multiple Wallet Exploitation: Sybil attacks are prevalent where users create multiple wallets to receive duplicate rewards.
  • Unfair Distribution: Structural inequality exists where benefits are skewed toward users with technical knowledge or capital.
  • Complex Defense Mechanisms: Existing protections (CAPTCHAs, whitelists, etc.) degrade user experience and increase development burden.

HumanPass Approach​

The FairDrop Protocol leverages HumanPass's human verification system to ensure tokens and assets are distributed only to real human users. This enables a fair and efficient Web3 asset distribution model.

Core properties:

  • Human-Gated Access: Only wallets that have completed human verification can participate, blocking bots at the source.
  • One-Wallet-One-Claim: SBT-based verification prevents one person from participating multiple times with different wallets.
  • Weighted Distribution: Additional rewards can be provided to more trustworthy users through HIS (Human Identity Score) weighting.
  • Airdrop SDK: FairDrop functionality can be integrated into dApps with simple API calls.

Technical Implementation​

The technical implementation of FairDrop Protocol consists of the following components:

  1. Human Verification Gateway

    • HumanPass SBT holding status verification
    • Authentication status and timestamp validation
    • Smart contract level verification logic

  2. Distribution Mechanisms

    • Support for various distribution strategies (equal, weighted, random)
    • HIS score-based tier system
    • Gas-optimized batch processing logic

  3. Developer Tools

    • Customizable airdrop configuration dashboard
    • Real-time distribution monitoring and analytics
    • Cross-chain bridges for multi-chain support
// FairDrop SDK Usage Example
import { FairDrop } from "@humanpass/fairdrop";

// Initialize FairDrop client
const fairdrop = new FairDrop({
  contractAddress: "0x...",
  tokenAddress: "0x...",
  chainId: 1,
});

// Configure airdrop
await fairdrop.configure({
  name: "Community Rewards Round 3",
  totalAmount: "100000", // Total distribution amount
  claimPeriod: 7 * 24 * 60 * 60, // 7 days (in seconds)
  distributionStrategy: {
    type: "weighted", // Weighted distribution
    hisThresholds: [
      // HIS score-based weights
      { min: 0, max: 50, weight: 1 },
      { min: 51, max: 80, weight: 1.5 },
      { min: 81, max: 100, weight: 2 },
    ],
  },
  humanVerificationRequired: true, // Human verification required
});

// Handle claims
async function handleClaim(userAddress) {
  const eligibility = await fairdrop.checkEligibility(userAddress);

  if (eligibility.isEligible) {
    const amount = eligibility.claimableAmount;
    await fairdrop.processClaim(userAddress, amount);
    return { success: true, amount };
  } else {
    return {
      success: false,
      reason: eligibility.reason, // 'not_human', 'already_claimed', etc.
    };
  }
}

Real-World Applications​

  • Incentive programs for testnet participants

NFT Projects

  • Fair public minting without whitelists
  • NFT distribution to community contributors
  • Event participation proof and POAP distribution

DAO and Community Rewards

  • Contributor reward systems
  • Participation incentive programs
  • Retroactive rewards distribution

Games and Metaverse

Strategic Impact​

FairDrop Protocol provides the following strategic value to the Web3 ecosystem:

  • Solving Bot Airdrop Problems: Fundamentally resolves the issue of automated bots claiming large quantities of tokens.
  • Maximizing Community Reward Efficiency: Ensures rewards go only to real users and contributors.
  • Fair Initial Distribution: Implements a Fair Launch model that provides equal opportunities to all participants.
  • Improved Token Economics: Supports the formation of healthy token economics from the initial distribution stage.

FairDrop Protocol is not just an airdrop tool but foundational infrastructure for fair resource distribution in the Web3 economy. This enables building healthier and more sustainable token ecosystems.
