Is Mina a layer 1 blockchain?
Could you please clarify for me if Mina qualifies as a layer 1 blockchain? I've heard various opinions on this matter, and I'm seeking a professional's perspective. Could you elaborate on the characteristics that define a layer 1 blockchain, and how Mina compares to those? Is it considered a standalone blockchain with its own native token and independent security mechanisms, or does it operate in a different manner? Your insights would be greatly appreciated.
