Vitalik recently shared an interesting thought that the Ethereum community needs a more radical approach to rethinking applications. And I agree that this makes sense. The point is that we shouldn't just improve what exists — we need to start from scratch and ask ourselves: if we were designing application architecture today, based on first principles, what would we create? Especially when it comes to DeFi, decentralized social networks, and identity. The core principles remain unchanged: resistance to censorship, openness, privacy, and security. But how we implement them at the application level — here, fundamental changes are needed. Vitalik emphasizes that privacy should now be considered a priority, not an add-on. This means a complete overhaul of the application stack because it has not been built with privacy in mind from the start. Interestingly, he talks about rethinking the role of L2. I see potential for real synergy between different layers here — L1 becomes more reliable, L2 provides scalability, and together they can create an ecosystem that works more efficiently than just the sum of its parts. This is reminiscent of how Bitcoin synergy works in a broader context — when different system components enhance each other. Another key idea is to abandon dependence on existing pathways. Imagine that Ethereum doesn't exist at all, and you're writing a white paper from scratch. What would you create? That’s exactly what needs to be done now. Psychologically, this means letting go of established notions, rethinking what it means to be a decentralized application in 2026. The thinking algorithm must change: instead of asking “what can we improve next in the current ecosystem?” we should ask “what is the most valuable thing we can create, given all the tools and knowledge at our disposal?” This is not just a technical rethinking; it’s a cultural rethinking. And it seems that Vitalik sees this as the key to reviving Ethereum as a platform that doesn’t just exist but truly innovates.
