They support a variety of configuration options through the [BlockTypeOptions](./server.blocktypeoptions.md) constructor argument. Block types are registered with a [BlockTypeRegistry](./server.blocktyperegistry.md) instance, allowing you to create custom blocks with unique visual representations and behaviors.
