Definition ∞ Layer-2 activity refers to the volume and nature of transactions and operations occurring on secondary scaling solutions built upon a base blockchain, such as Ethereum. This activity includes executing smart contracts, transferring tokens, and interacting with decentralized applications that leverage Layer-2 technologies. An increase in Layer-2 activity indicates growing adoption of these scaling solutions, signifying a shift of transactional load away from the main chain. It reflects the practical utility of these advanced protocols.
Context ∞ The monitoring of Layer-2 activity is a key metric for assessing the effectiveness of blockchain scaling efforts and the overall health of decentralized ecosystems. Sustained growth in this area suggests that networks are successfully addressing throughput and cost limitations of their underlying Layer-1. A critical future development involves the continued expansion and integration of Layer-2 solutions, which are vital for supporting a future where blockchain applications can accommodate a global user base with efficient and affordable transactions.
