The Inter-Blockchain Communication protocol (IBC) allows blockchains to talk to each other. This end-to-end, connection-oriented, stateful protocol provides reliable, ordered, and authenticated communication between heterogeneous blockchains.
This IBC implementation in Golang is built as a Cosmos SDK module. To understand more about how to use the ibc-go
module as well as about the IBC protocol, please check out the Interchain Developer Academy section on IBC, or our docs.
For an overview of upcoming changes to ibc-go take a look at the roadmap.
This roadmap is also available as a project board.
