LAYER 2s
Layers Explained
Layer 2 (L2) crypto is a network or channel that sits on top of a Layer 1 (L1) network, like Bitcoin or Ethereum, to improve the speed and reduce the cost of transactions on a blockchain. L2 networks are secondary protocols that handle transactions off the main blockchain, thereby reducing congestion and fees on the original network.
