Layer 2 networking
**Layer 2 networking**
What is Layer 2 networking?
Layer 2 networking, also known as the Data Link Layer, is the second layer in the OSI model. It provides node-to-node data transfer between two directly connected nodes. It handles error detection and correction, media access control (MAC) addressing, and framing of data for transmission over the physical layer. Common Layer 2 technologies include Ethernet, Wi-Fi, and various point-to-point protocols. It's often used to create local area networks (LANs) and manage data flow between devices on the same network segment. In blockchain, Layer 2 solutions aim to improve scalability by processing transactions off the main chain and then anchoring the results back on-chain.
