// Debug manages an RPC service that exports methods to debug a failed node.

// After a node shuts down due to a consensus failure,, it will no longer start
|
|
// up and cannot easily be inspected. A Debug value provides a similar interface
|
|
// to the node, using the underlying Tendermint data stores, without bringing up
|
|
// any other components. A caller can query the Debug service to inspect the
|
|
// persisted state and debug the failure.
