Body

application/json

atBlockIdentifiers (object)

Block number and hash at which the call was made.

authoringVersionstring

The version of the authorship interface. An authoring node will not attempt to author blocks unless this is equal to its native runtime.

chainTypeChainType (object)

Type of the chain. It will return one of the following enum variants as a key. Live, Development, Local, or Custom. Each variant will have a value as null except when the ChainType is Custom, it will return a string.

Example: "{\"live\": null}"

implVersionstring

Version of the implementation specification. Non-consensus-breaking optimizations are about the only changes that could be made which would result in only the impl_version changing. The impl_version is set to 0 when spec_version is incremented.

specNamestring

Identifies the different Substrate runtimes.

specVersionstring

Version of the runtime specification.

transactionVersionstring

All existing dispatches are fully compatible when this number doesn't change. This number must change when an existing dispatchable (module ID, dispatch ID) is changed, either through an alteration in its user-level semantics, a parameter added/removed/changed, a dispatchable being removed, a module being removed, or a dispatchable/module changing its index.

propertiesobject

Arbitrary properties defined in the chain spec.
