Is SKL a layer 2?
Could you please elaborate on whether SKL qualifies as a layer 2 solution in the cryptocurrency ecosystem? I'm particularly interested in understanding if SKL introduces scalability improvements by offloading some of the transactional load from the underlying blockchain, while still maintaining the security guarantees of the main chain. Additionally, does SKL leverage any specific techniques or protocols that are commonly associated with layer 2 solutions, such as state channels, sidechains, or rollups? Clarifying these aspects would help me determine if SKL truly functions as a layer 2 solution.
