  Layer 2 protocols are secondary frameworks built on top of existing blockchain networks to enhance scalability and reduce transaction fees. Some of the commonly used layer 2 protocols in the cryptocurrency industry include Lightning Network, Plasma, and State Channels. These protocols enable off-chain transactions, allowing users to conduct faster and cheaper transactions without congesting the main blockchain. By moving a large number of transactions off-chain, layer 2 protocols help to alleviate network congestion and improve scalability.

  When it comes to layer 2 protocols in the cryptocurrency industry, one name that stands out is the Lightning Network. Developed as a second layer solution for Bitcoin, Lightning Network enables fast and cheap transactions by creating payment channels between users. By conducting transactions off-chain and only settling the final result on the Bitcoin blockchain, Lightning Network significantly improves scalability and reduces transaction fees. Other layer 2 protocols like Plasma and State Channels also offer similar benefits, providing alternative solutions for scaling blockchain networks.
