Unlike Web2 where data lives on centralized servers, Web3 applications store state on distributed ledgers, giving users ownership of their data and digital assets.\n\nThe Web3 stack includes smart contracts (on-chain logic), decentralized storage (IPFS, Arweave), and frontend interfaces that connect to blockchain via wallets.\n\n## Smart Contract Fundamentals\n\nSmart contracts are self-executing programs deployed on a blockchain. Once deployed, their code cannot be changed — this immutability is both a feature and a risk.\n\n### Solidity (Ethereum\u002FEVM)\n```solidity\ncontract SimpleToken {\n    mapping(address => uint256) public balances;\n    \n    function transfer(address to, uint256 amount) external {\n        require(balances[msg.sender] >= amount, \"Insufficient balance\");\n        balances[msg.sender] -= amount;\n        balances[to] += amount;\n    }\n}\n```\n\n### Tact (TON Blockchain)\n```\ncontract Counter {\n    val: Int as uint32 = 0;\n    \n    receive(\"increment\") {\n        self.val = self.val + 1;\n    }\n}\n```\n\n## DeFi Application Architecture\n\nDecentralized Finance (DeFi) applications typically consist of:\n\n1. **Smart contracts** — Core business logic (lending pools, AMM, staking)\n2. **Oracle integration** — Price feeds from Chainlink, Pyth, or RedStone\n3. **Frontend** — React\u002FVue app connecting via ethers.js or web3.js\n4. **Indexer** — The Graph or custom indexer for querying blockchain events\n5. **Backend** — API for off-chain computations, user management, notifications\n\n## Choosing the Right Blockchain\n\n| Blockchain | TPS | Fees | Language | Best For |\n|-----------|-----|------|----------|----------|\n| Ethereum | ~30 | High | Solidity | DeFi, NFTs |\n| TON | 100K+ | Low | Tact\u002FFunC | Telegram integration |\n| Solana | 65K | Low | Rust | High-frequency trading |\n| Polygon | 7K | Very Low | Solidity | Gaming, social |\n\n## Security Auditing Best Practices\n\nSmart contract vulnerabilities can lead to catastrophic fund losses. Essential security measures:\n\n- **Reentrancy protection** — Use checks-effects-interactions pattern\n- **Integer overflow** — Use SafeMath or Solidity 0.8+ built-in checks\n- **Access control** — Implement role-based permissions (OpenZeppelin AccessControl)\n- **Oracle manipulation** — Use time-weighted average prices (TWAP)\n- **Formal verification** — Mathematically prove contract correctness\n\nAlways get a professional audit before mainnet deployment.\n\n## Conclusion\n\nWeb3 development requires a different mindset from traditional software engineering. Immutability, gas optimization, and adversarial thinking are core skills. Whether building on Ethereum, TON, or Solana, the fundamentals of secure smart contract development remain the same.","\u003Ch2 id=\"what-is-web3-development\">What Is Web3 Development?\u003C\u002Fh2>\n\u003Cp>Web3 development builds decentralized applications (dApps) on blockchain networks.
