Vitalik Buterin: Ethereum Must Pass “The Walkaway Test”
The post Vitalik Buterin: Ethereum Must Pass “The Walkaway Test” appeared on BitcoinEthereumNews.com.
Key Notes Vitalik Buterin said that Ethereum must function even if its core developers disappear. The protocol should already contain everything needed to run safely for decades, he said. He added that scaling, security, and upgrades must become optional, not required for survival. Vitalik Buterin says Ethereum ETH $3 106 24h volatility: 0.2% Market cap: $374.77 B Vol. 24h: $18.66 B must be able to survive even if its core developers walk away. In a recent post on X, he argued the base layer cannot rely on constant human intervention to remain usable. If applications are meant to be trust-minimized tools, the chain they run on must meet the same standard, Buterin said. The test is simple: Ethereum should still function safely, predictably, and usefully without ongoing protocol changes. That does not mean upgrades stop. It means Ethereum’s value should not depend on future promises. “Ethereum the blockchain must have the traits that we strive for in Ethereum’s applications. Hence, Ethereum itself must pass the walkaway test,” the entrepreneur said. Ethereum itself must pass the walkaway test. Ethereum is meant to be a home for trustless and trust-minimized applications, whether in finance, governance or elsewhere. It must support applications that are more like tools – the hammer that once you buy it’s yours – than like… — vitalik.eth (@VitalikButerin) January 12, 2026 Ossification Is a Feature, Not a Risk Buterin argues Ethereum must reach a point where it can “ossify” by choice. The protocol should already contain everything needed to operate securely for decades. Further changes should be optional optimizations, not survival requirements. That includes full quantum resistance, so today’s cryptography remains trustworthy for decades. It also means scaling designs that rely on parameter changes rather than constant hard forks. PeerDAS and ZK-EVM validation are significant for this plan. As…
