The application of recursion in blockchain is mainly reflected in creating new digital objects, where the existing digital objects are used as templates. By modifying or expanding the structure and attributes of the existing objects, new digital objects are generated. This recursive operation enables digital objects in blockchain to have a hierarchical structure, realizing flexible management and processing of complex digital objects."}]}],"pr":"51730c98ac75cca550083d48eb0ebafe2797019cef66d358dc24b599a1d301ac"}
