IBC-Go Documentation
Welcome to the IBC-Go documentation!
The Inter-Blockchain Communication protocol (IBC) is an end-to-end, connection-oriented, stateful protocol for reliable, ordered, and authenticated communication between heterogeneous blockchains arranged in an unknown and dynamic topology.
IBC is a protocol that allows blockchains to talk to each other.
The protocol realizes this interoperability by specifying a set of data structures, abstractions, and semantics that can be implemented by any distributed ledger that satisfies a small set of requirements.
IBC can be used to build a wide range of cross-chain applications that include token transfers, atomic swaps, multi-chain smart contracts (with or without mutually comprehensible VMs), and data and code sharding of various kinds.
