Substrate is a Software Development Kit(SDK) designed to be modular, flexible, and highly customizable, allowing us to build our own blockchain applications within 15 mins.

It provides us with all of the fundamental components a blockchain requires so we can just focus on crafting the logic that makes us chain unique and innovative.

All of the Substrate architecture and tooling is free to use (for those interested in exploring the source code, check out the repository here), and all substrate-based blockchains can interoperate with the other blockchains through Cross-Consensus Messaging (XCM).

Overall, it is a powerful and versatile framework for building blockchain networks and customised blockchain applications. Depending on your background and interests, explore my articles to learn more.
