๐๐ฎ๐๐ฒ๐ฟ-2 ๐๐น๐ผ๐ฐ๐ธ๐ฐ๐ต๐ฎ๐ถ๐ป๐: To address the limitations of Layer-1, Layer-2 solutions emerged. Layer-2 built on top of Layer-1, they enhance scalability and efficiency while maintaining a high level of security.
๐๐ฎ๐๐ฒ๐ฟ-3 ๐๐น๐ผ๐ฐ๐ธ๐ฐ๐ต๐ฎ๐ถ๐ป๐: There were still some limitations that couldn't be addressed by Layer-1 and Layer-2 blockchains.
Therefore, Layer-3 blockchains were developed to focus on interoperability and customization, providing the flexibility needed for advanced applications and services.
