Understanding Gas and Optimization in Smart Contracts

Tutorial August 22, 2024
solidity

  • Reduce redundant calculations or operations within your smart contract. Precompute values where possible and reuse them.
  • Example: Store the result of a complex computation in a variable rather than recalculating it multiple times.

Several tools can help you analyze and optimize gas consumption in your smart contracts:

Building a Decentralized Application (DApp) with Smart Contracts

Tutorial August 22, 2024
solidity

Steps to Compile and Deploy:

  • Run truffle init in your terminal to create a new Truffle project.
  • Place your smart contract code in the contracts/ directory.

Explanation:

  • pragma solidity ^0.8.0;: Specifies the version of Solidity.
  • contract SimpleStorage: Defines a new smart contract named SimpleStorage.
  • uint256 public storedData: Declares a public variable to store an unsigned integer.
  • function set(uint256 x) public: A function to set the value of storedData.
  • function get() public view returns (uint256): A function to retrieve the value of storedData.
