Expand description

Extension to signal to [crypt::ed25519_verify] to use the dalek crate.

The switch from ed25519-dalek to ed25519-zebra was a breaking change. ed25519-zebra is more permissive when it comes to the verification of signatures. This means that some chains may fail to sync from genesis when using ed25519-zebra. So, this extension can be registered to the runtime execution environment to signal that ed25519-dalek should be used for verification. The extension can be registered in the following way:

client.execution_extensions().set_extensions_factory(
	// Let the `UseDalekExt` extension being registered for each runtime invocation
	// until the execution happens in the context of block `1000`.
	sc_client_api::execution_extensions::ExtensionBeforeBlock::<Block, UseDalekExt>::new(1000)
);
