Layer2 is the network layer used to transfer data between adjacent network nodes in a wide area network or between nodes on the same local area network . A frame is a protocol data unit, the smallest unit of bits on a Layer 2 network.
Read moreWhat is the function of layer 2?
Layer 2 of The OSI Model: Data Link Layer provides the functional and procedural means to transfer data between network entities and to detect and possibly correct errors that may occur in the physical layer .
Read moreWhat is Layer 2 scaling?
Layer 2 solutions to scaling establish an additional protocol that is built on top of blockchains like those of Ethereum and Bitcoin . Layer 2 scaling solutions increase throughput without tampering with any of the original decentralization or security characteristics that are integral to the original blockchain.

A rollup is a scaling solution that executes transactions on its own optimized execution layer but posts its transaction data to Ethereum (and later perhaps other L1s). In this way, rollups directly inherit Ethereum’s security guarantees. Zooming in, there are two main types: zk rollups and optimistic rollups.
