Understanding Blockchain Scalability Challenges 

Blockchain, in its fundamental design, offers decentralization and security through a distributed ledger. However, as the number of transactions on a blockchain network increases, so does the strain on its scalability. The inherent trade-off between decentralization, security, and scalability has led to the exploration of innovative solutions to enhance the efficiency of blockchain networks. 

What are Layer 2 Solutions? 

Layer 2 solutions are scalability mechanisms built on top of existing blockchain protocols, providing a way to process transactions off-chain or in a more efficient manner.
