Ganache
Ganache is a personal blockchain for Ethereum development that allows developers to deploy contracts, develop applications, and run tests in a local environment. It simulates a full Ethereum network with features like deterministic addresses, instant mining, and a built-in block explorer. It is commonly used for testing and debugging smart contracts and decentralized applications (dApps) without needing real Ether or connecting to public testnets.
Developers should use Ganache when building and testing Ethereum-based applications, as it provides a fast, isolated, and predictable environment for development. It is essential for unit testing smart contracts, debugging transactions, and simulating network conditions without incurring gas costs or relying on external networks. Use cases include rapid prototyping, automated testing in CI/CD pipelines, and educational purposes for learning blockchain development.
