Ethereum co-founder Vitalik Buterin has outlined a long-term vision for the network that centers on what he calls the “walkaway” test.
Buterin’s walkaway test is a standard meant to ensure Ethereum can remain functional, secure, and valuable even if its core developers were to step away. The principle reflects Ethereum’s original goal of being a foundation for trustless and trust-minimized applications across finance, governance, and other domains.
According to the Ethereum co-founder, applications built on the blockchain should behave more like durable tools than fragile services. Once users adopt them, they should not lose core functionality simply because a vendor stops maintaining the software, gets hacked, or becomes value extractive.
Ethereum can reduce its reliance on centralized actors, but this is only possible if the base layer itself does not rely on continual intervention from a governing group, even one as open as the all-core developers process.
Buterin argues that Ethereum must reach a point where it can ossify when necessary to pass the walkaway test. That does not mean halting innovation, but ensuring that Ethereum’s value proposition does not depend on features that have yet to be added.
In practice, this requires the protocol to be robust enough that future progress can occur through optimization and parameter adjustments rather than constant structural changes.
Buterin highlighted several areas that must be addressed to reach this state. These include full quantum resistance, so the protocol can credibly claim cryptographic safety over a century-long horizon.
Ethereum must also support an architecture capable of scaling to thousands of transactions per second over time, with ZK EVM validation and data availability solutions such as PeerDAS playing a central role.
Other vital components include a durable state architecture, complete account abstraction beyond ECDSA, and a gas schedule resistant to denial-of-service attacks.
Moreover, the Ethereum co-founder emphasized the importance of a proof-of-stake model that can remain decentralized for decades and support ETH’s role as trustless collateral. He also pointed to the need for a block building model that preserves censorship resistance under unknown future conditions.
Ultimately, Buterin believes Ethereum should methodically address these challenges over the coming years, checking off key milestones and maximizing both technological and social resilience.
