Build a Blockchain Ticket Resale Platform with Anti-Scalping Mechanism
Use blockchain and smart contracts to issue tamper-proof tickets, prevent scalping, and enable fair resale with price caps and verified ownership.Traditional ticketing platforms are vulnerable to scalping, counterfeit tickets, and resale fraud. Blockchain provides a tamper-proof, transparent system where ticket ownership is verifiable and resales can be controlled through smart contracts.
Create a decentralized ticketing system where event organizers issue NFT-based tickets with embedded resale logic. Ownership is tracked on-chain, and resale conditions such as price caps, date limits, or whitelisting are enforced automatically.
NFT-Based Tickets
Each ticket is a unique, non-fungible token (NFT) that proves ownership and prevents duplication.
Smart Contract Resale Rules
Resale conditions such as price limits, time restrictions, and approved buyers are embedded in the contract.
Fraud-Proof Ticket Validation
Event staff can validate ticket ownership through on-chain verification, eliminating fake tickets.
Transparent Marketplace
Users can buy, sell, or transfer tickets in a decentralized secondary market with full transparency.
Tickets are issued as ERC-721 NFTs by event organizers. Ownership transfers are tracked on-chain, and smart contracts handle resale conditions. A frontend allows users to browse, buy, or sell tickets with wallet-based login. QR codes and wallet signatures are used for validation at entry.
- ERC-721 smart contracts for ticket creation and resale enforcement
- React.js frontend with event listings and user dashboards
- Web3 wallet integration (MetaMask, WalletConnect)
- QR code ticket scanning for entry validation
- Optional IPFS storage for ticket metadata and event media
Blockchain
Polygon or Ethereum (L2) for minting and resale
Smart Contracts
Solidity with ERC-721 and resale condition logic
Frontend
React.js + Ethers.js + QR scanner for validation
Storage
IPFS/Web3.Storage for event media and ticket designs
1. Create Ticket NFT Smart Contract
Mint ERC-721 tokens with metadata and assign them to buyers upon purchase.
2. Implement Resale Rules
Define rules in the contract to enforce pricing limits, resale window, or whitelisted buyers.
3. Build Ticket Marketplace UI
Allow users to list, search, and purchase tickets directly from each other.
4. Add QR Code Verification System
Generate QR codes for each ticket and validate ownership using smart contract queries at entry points.
5. Launch on Testnet with Demo Events
Test various ticketing workflows and scalping edge cases on Goerli or Mumbai testnet.
Fight Scalping and Fraud with Blockchain Tickets
Build a future-proof ticketing platform where trust, control, and fair pricing are embedded in code.
