Definition ∞ L1 scalability refers to the capacity of a Layer 1 blockchain, such as Ethereum or Bitcoin, to process a high volume of transactions quickly and efficiently. It addresses the fundamental challenge of increasing transaction throughput directly on the main blockchain without compromising decentralization or security. Solutions often involve adjustments to the core protocol, like sharding or increased block size limits. Improving L1 scalability is crucial for wider adoption of blockchain technology.
Context ∞ The ongoing discussion surrounding L1 scalability centers on achieving a balance between transaction speed, cost, and the foundational principles of decentralization and security. There is a continuous debate about the optimal approaches, including protocol upgrades and the synergy with Layer 2 solutions. Future developments are expected to deliver significant advancements in L1 throughput, supporting a more robust and accessible blockchain ecosystem.
