IBC

Synopsis

This repository is the canonical location for development and documentation of the inter-blockchain communication protocol (IBC).

It shall be used to consolidate design rationale, protocol semantics, and encoding descriptions for IBC, including both the core transport, authentication, & ordering layer (IBC/TAO) and the application layers describing packet encoding & processing semantics (IBC/APP).

Contributions are welcome. See CONTRIBUTING.md for contribution guidelines.

What is IBC?

For a high-level explanation of what IBC is and how it works, please read this blog post.
