The future of Ethereum's scalability lies in a combination of Layer 1 (L1) and Layer 2 (L2) solutions. L1 is favored by whales, governments, and corporations for its neutrality and risk minimization, while L2s offer scalability for a world with multiple chains. Various projects like Starknet, zkSync, and Arbitrum are innovating to enhance privacy, scalability, and security within the Ethereum ecosystem. The industry is witnessing a surge in L2 activity, with solutions like Arbitrum outpacing Ethereum in daily transactions. The focus is on building advanced L2 stacks to improve scaling and reduce compute costs. The Ethereum community is exploring different approaches to L2 development, emphasizing the importance of decentralization and strong settlement security.
