…Examples of on-chain scaling solutions include SegWit and sharding.Layer-2 off-chain scalability solutions add a second layer to the main blockchain (mainchain) network to facilitate faster and more transactions. The secondary protocols are built on top of the mainchain, where transactions are ‘offloaded’ to save space and reduce network congestion. Examples include sidechains and payment channels like Lightning Network (Bitcoin) and Arbitrum (Ethereum).Key TakeawayBlockchain scalability ref…
