Build Your First Interchain App in 30 Minutes - Cosmos SDK, IBC, and Spawn Tutorial

In this video, you'll see how to create your first custom appchain and run it locally with spawn and local-ic. This chain is Inter-Blockchain Communication (IBC)-enabled, and we'll walk you through creating a name service similar to ENS, but for cross-chain naming. Reece shows Ollie how to do this first hand!

The interchain moves faster. 🚀 The content of this video was correct at the time of recording. ► About IBC Inter-Blockchain Communication Protocol (IBC) is a fundamental paradigm shift in interoperability, allowing for arbitrary data transfer across blockchains in a trust-minimized, secure, and extensible manner. While incubated within the #Cosmos ecosystem, IBC is now being adopted across blockchain ecosystems - from Polkadot and Kasuma, to NEAR Protocol, Hyperledger and Corda blockchain.

Written in Go, Cosmos SDK allows developers to quickly and easily build and deploy application-specific blockchains, reducing time to market, using a framework that is stable, secure and highly performant. Cosmos SDK is the native application-building toolkit for Cosmos appchains and at the core of the interchain.
