Vitalik: The growth of the application layer is precisely the time when a good social philosophy is most needed

ChainCatcher message, in response to the statement "The self-updating of Ethereum requires generational/talent replacement. And the next generation needs to be rooted in Ethereum values (such as cypherpunk)," Vitalik Buterin replied on Warpcast: "I actually think that the growth of the application layer is precisely the time when good social philosophy is most needed. To put it another way: suppose C++ was developed by a totalitarian racist fascist. Would it be a worse language? Probably not. C++ is general-purpose and has little room for bad social philosophy to corrupt it (or for good social philosophy to improve it). Ethereum Layer-1 is not entirely like that: those who do not believe in decentralization will not add light clients, FOCIL, or (good forms of) account abstraction; those who do not care about energy waste will not spend five years migrating to PoS. But in any case, the opcodes of the EVM might be roughly the same. Therefore, Ethereum might be 50% general-purpose. Applications are about 80% specialized. What kind of applications you build largely depends on your ideas about what Ethereum applications (and Ethereum as a whole) will do for the world. Thus, having good ideas on this topic becomes crucial."Additionally, Vitalik listed some applications, considering good applications like Railgun, Farcaster, Polymarket, Signal, and bad ones like Pump.fun, Terra/Luna, FTX. He believes that the differences in application functionality stem from developers holding different beliefs about the goals they want to achieve.

Vitalik proposed the "L2 Security and Finality Roadmap," highlighting the three core directions of Ethereum L2

ChainCatcher news, Ethereum founder Vitalik Buterin published a long article titled "A simple L2 security and finalization roadmap," which outlines three core directions for optimizing Ethereum L2 security and finality:Expand data capacity: Increase the Blob space to 6 through the Pectra upgrade, and expand it to 72 (or gradually increase to 12-24) in the upcoming Fusaka upgrade at the end of the year, to meet the L2 transaction throughput demands;Implement a hybrid proof system for rapid finality: Use a 2/3 multi-signature mechanism (optimistic proof + ZK proof + TEE trusted hardware proof). If ZK and TEE verify simultaneously, finality is immediate; if only one is verified, it requires a 7-day optimistic challenge period. The security committee can urgently upgrade the proof logic but is subject to a 30-day delay, balancing immediate finality with attack resistance;Build a unified ZK proof aggregation layer: Standardize the proof aggregation protocol across the ecosystem, allowing multiple applications to share the cost of a single proof (e.g., 500,000 Gas), significantly reducing ZK verification overhead and promoting the adoption of L2, privacy protocols, and other scenarios. The goal of this roadmap is to achieve L2 cross-chain bridging finality within 1 hour and reduce costs through short-term hybrid verification mechanisms, while gradually eliminating TEE reliance with a long-term goal of full ZK implementation, ultimately establishing an efficient, secure, and trustless L2 ecosystem.
