Wu Shuo learned that Ethereum founder Vitalik Buterin published a blog post discussing Ethereum's L1 and L2 scaling strategies for 2025 and beyond. Vitalik pointed out that L2 protocols are the core pathway for Ethereum's expansion, and their technological and social collaboration has brought Ethereum close to "escape velocity," meaning sufficient network effects and value accumulation to facilitate its continuous growth. At the same time, Vitalik highlighted two major challenges: scaling capacity and heterogeneity issues (including standards, interoperability, proof system security, user experience, and economic models). He proposed targeted solutions, including increasing data block capacity, optimizing L2 proof system security, accelerating the advancement of interoperability standards, and strengthening $ETH's core position in the Ethereum economy.
