Substrate runtime version
Each runtime that should be executed by a Substrate based node needs to have a runtime version.
The runtime version is defined by [RuntimeVersion
]. The runtime version is used to
distinguish different runtimes. The most important field is the
spec_version
. The spec_version
should be increased in a
runtime when a new runtime build includes breaking changes that would make other runtimes unable
to import blocks built by this runtime or vice-versa, where the new runtime could not import
blocks built by the old runtime. The runtime version also carries other version information
about the runtime, see [RuntimeVersion
] for more information on this.
Substrate will fetch the runtime version from a wasm
blob by first checking the
runtime_version
link section or calling the Core::version
runtime api. The link section can
be generated in the runtime using the [runtime_version
] attribute. The Core
runtime api also
needs to be implemented for the runtime using impl_runtime_apis!
