About

The problem it 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. 3. 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).

How it's made

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.
