Substrate is a framework used to build blockchain-based applications. It provides a set of tools and components that developers can use to create custom blockchains quickly and efficiently.At its core, Substrate offers flexibility, allowing developers to choose what features to include in their blockchain. This can range from consensus mechanisms to governance protocols. By using Substrate, developers don’t have to start from scratch; they can leverage existing modules and functionalities.Substrate is also designed to be interoperable, meaning blockchains built with it can easily communicate with one another. This facilitates the creation of a network of diverse blockchains that can share information and resources.Additionally, it supports upgrading blockchains without going through a hard fork. This feature allows projects to evolve and adapt over time, helping to ensure long-term viability and innovation. Overall, Substrate streamlines the development process, making it easier for teams to focus on their unique goals rather than the underlying infrastructure.
