Is CKB a layer 1?
Could you please clarify for me if CKB qualifies as a layer 1 in the context of blockchain technology? I'm trying to understand its position within the cryptocurrency ecosystem and how it differs from other layers. Could you also explain what makes a blockchain layer 1 and how CKB specifically fulfills that role? I'm particularly interested in its functionalities and how it interacts with other components of the blockchain infrastructure. Thank you for your assistance in clarifying this matter.
