Ethereum co-founder Vitalik Buterin has called on the ecosystem to adopt a far bolder and more open mindset, particularly at the application layer. In a recent post on X, he wrote: “I think it’s healthy for us in the Ethereum world to have a more bold and open mindset to many things, especially on the application layer and on how we see ourselves in the world.” He argued this mindset should encourage radical rethinking of existing assumptions—from the way decentralized finance protocols are structured to how end users interact with dApps.
AI Could Overhaul Wallets and Privacy Design
Buterin pointed to AI-driven transformation as a potential game-changer, suggesting wallets and traditional dApp interfaces could evolve beyond recognition within a short time frame. He also elevated privacy to a top-tier priority, advocating for it to be treated as a first-class concern. That shift, he noted, might require building an entirely different Ethereum application stack rather than retrofitting existing frameworks.
Layer-2 Needs a Fresh Start, Not Incremental Patches
Regarding the proliferation of Layer-2 networks, Buterin stressed the need to redesign them from scratch—focusing on which architectures truly complement Ethereum and add unique value, rather than piling on marginal improvements. He urged developers to break free from path dependency, asking what Ethereum applications would look like if they were designed with a clean slate today.
CROPS: Hard Lines That Cannot Be Blurred
While pushing for experimentation, Buterin drew a firm line around core principles. He reiterated that censorship resistance, open source, privacy, and security—collectively known as CROPS—are non-negotiable properties that preserve the network’s integrity. “We should not have ‘open mindedness’ of the type that leaves people with no confidence of what security properties the L1 will still have one year from now,” he wrote. Innovation, he said, must never erode trust in Layer-1 security guarantees.
FOCIL and EIP-8141: Reinforcing the Foundation
Beyond conceptual calls, Buterin threw his weight behind two concrete technical proposals. FOCIL (Fork-Choice Enforced Inclusion Lists) is designed to curb the growing influence of dominant block builders by requiring certain validators to enforce the inclusion of specific transactions, thereby preventing censorship and preserving decentralization. EIP-8141 introduces “frame transactions” as part of Ethereum’s push toward native account abstraction, allowing more flexible validation rules and gas payment schemes—an enabler for advanced wallet designs and improved user experience across decentralized applications.
