The problem Dandelion solves

Amid the booming digital economy, task bounty platforms have become crucial bridges connecting demand-side clients with service providers. While traditional centralized platforms like Freelancer and Upwork have established large user bases, their operational mechanisms reveal significant structural flaws:

• Excessive Fees: Standard 10%-20% transaction commissions (up to 30% in specialized sectors), compressing earnings. Industry reports indicate global platform commissions exceeded $8 billion in 2024, with nearly 60% retained as centralized operational costs.
• Centralized Trust Risks: Platforms as absolute authorities pose risks including arbitrary rule modifications and opaque data handling. A 2023 incident involving frozen user funds (100,000 affected) exposed security vulnerabilities. Fraud rates reach 15% annually, with dispute resolution averaging 21 days.
• Payment Limitations: Cross-border transactions incur high fees (3%-5%) and 3-7 day settlement periods. 62% of freelancers abandon long-term projects due to payment delays; 38% of employers switch to local alternatives.
• Process Opacity: Lack of verifiable audit trails for task execution/review. 73% of users question arbitration fairness (2024 survey).

Project Positioning & Core Solution

To address these pain points, we introduce Dandelion—a fully on-chain decentralized task bounty platform that rebuilds trust through blockchain technology:

• Full-scenario Coverage: Supports software development, design, market research, and Web3-specific tasks.
• Global Collaboration: Enables borderless cooperation via cross-chain technology and decentralized storage.

Core Solutions

Economic Model Optimization:

1. Fee Structure: Charges only base Gas fees (80% lower than ETH) + 0.5% ecosystem maintenance fee (95% cost reduction).
2. Fund Escrow: Bounties held in smart contracts; auto-released upon task completion.

Technical Architecture:

1. Task Lifecycle: Solidity smart contracts manage creation, bidding, execution, and acceptance.
2. Web3 Integration: Chainlink oracles verify GitHub commits; milestone-based delivery with IPFS storage for demos/reports.

Trust Reconstruction:

• Tripartite Arbitration:
  1. Disputed parties stake arbitration deposits.
  2. Odd-numbered DAO jurors randomly selected.
  3. On-chain voting using task data.
• Credit System: Generates portable, on-chain reputation scores for employers/executors.

Infrastructure:

1. Cross-chain Payments: <0.3% slippage via AnySwap (supports ETH/USDC/BNB).
2. Immutable Storage: Critical data stored on blockchain + IPFS (default permanent retention).

Challenges we ran into

How to Protect Project Contributors' Intellectual Property Rights
The NFT acts as a cryptographically secured, blockchain-based escrow certificate for the IP rights. Ownership, demonstrably tied to the creator and the specific work, remains with the freelancer until the condition of payment is met on-chain, at which point ownership is programmatically transferred to the employer. This creates a transparent and enforceable framework for IP transfer in freelance engagements.
