What is ARPA called now?

Could you please clarify what you mean by "ARPA"? Are you referring to the Advanced Research Projects Agency, which was established by the United States government in the 1950s to fund cutting-edge research in areas such as information technology, or is there a specific cryptocurrency or financial project that goes by the name ARPA that has undergone a renaming? If it's the latter, could you provide some context or background information to help me better understand the question? Additionally, are you asking for the current name of this project or entity, or are you seeking clarification on its status or purpose?
