Is Nubank a Brazilian bank?

Could you please clarify for me: is Nubank considered a traditional Brazilian bank, or does it operate in a different manner within the financial landscape of Brazil? I'm interested in understanding its positioning within the banking system and how it might differ from other institutions. Could you elaborate on its characteristics and how it serves its customers? I'm particularly curious about its digital offerings and whether it's a fully digital bank or if it also maintains physical branches. Thank you for your assistance in clarifying this matter.
