A module in cryptocurrency refers to a self-contained unit of functionality that can be integrated into a blockchain system or application. Modules can handle specific tasks, such as transaction processing, smart contract execution, or user wallets, allowing developers to build and expand applications more efficiently.These modules promote reusability and collaboration, as different developers can create and share modules for common functionalities. This modular approach enables easier updates and enhancements, as individual modules can be replaced or upgraded without affecting the entire system.Additionally, modules can enhance the adaptability of a blockchain platform, allowing it to support various features and protocols. By using modules, projects can better tailor their solutions to meet specific market demands while maintaining the ability to innovate and evolve over time.
