Smart contracts are an essential part of blockchain technology, enabling trustless transactions and automation of agreements. In this guide, we'll explore some common patterns used in smart contract development.

Common Patterns

  1. Immutable Storage 📚

    • Smart contracts should store data in an immutable manner to ensure data integrity and prevent fraud.
    • Example: Use a Merkle tree to store large amounts of data efficiently.

  2. Event-Driven Architecture 🎉

    • Design smart contracts to be event-driven, allowing them to react to external events and trigger internal actions.
    • Example: Listen to a new block event and update the state of the contract accordingly.

  3. Access Control 🔐

    • Implement access control to restrict who can interact with the smart contract.
    • Example: Use role-based access control (RBAC) to manage permissions.

  4. Gas Optimization 💨

    • Optimize smart contracts to minimize gas consumption, which can help reduce transaction costs.
    • Example: Use loops and conditionals efficiently and avoid unnecessary state changes.

  5. Upgradeability 🔧

    • Design smart contracts to be upgradeable, allowing for improvements and fixes without deploying a new contract.
    • Example: Use a proxy pattern to delegate calls to an upgradeable implementation.
