Share and Learn
All Things Substrate

Join us for Sub0 Online to talk all things Substrate, the blockchain development framework.

Sub0 Online brings together blockchain developers around the world to learn and share about building innovative Web3 solutions using Substrate.

Substrate is the user-friendly, powerful, and flexible blockchain-development framework—one that allows developers to build new decentralized solutions to fruition faster and easier than ever before.

We will be taking a deep-dive into different features of Substrate and showcasing projects currently building with the blockchain framework.

You can expect talks from Polkadot founder Gavin Wood, Substrate developers, and projects currently building with Substrate.
