This is a more technical resource for people interested in the top Layer 2 scaling solutions. Scaling solutions are developed to help reduce Ethereum transaction fees and increase the scalability of the network by moving the transactions off chain, then bringing them back to Ethereum for final settlement. L2BEAT defines Layer 2 as "We define layer two as a chain that fully or partially derives its security from layer one Ethereum so that users do not have to rely on the honesty of L2 validators for the security of their funds.".
