-The Inter-Blockchain Communication protocol (IBC) allows blockchains to talk to each other. IBC handles transport across different sovereign blockchains. 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.
