fabric-ibc-lightclientd
is a standalone daemon meant to offload implementation cost of Fabric-IBC light client logic.
By using this internally, IBC implementers can easily develop ClientState for Fabric-IBC in their own IBC implementation.
fabric-ibc-lightclientd
runs as a gRPC server listening to a specified port.
ClientState (for Fabric IBC) in your IBC implementation just works as a shim layer for this server.
