Vitalik Buterin outlines conditions for a self-sustaining, quantum-safe Ethereum

Quick Take

  • Ethereum co-founder Vitalik Buterin detailed seven protocol requirements, including century-scale quantum resistance, that he argues are necessary for Ethereum to be able to ossify if it chooses to.
  • Buterin called this a “walkaway test” that, if passed, would mean Ethereum’s core protocol would no longer strictly depend on continuous active stewardship to remain usable.

Ethereum co-founder Vitalik Buterin has outlined a clear technical threshold for what he considers network maturity, arguing its foundational protocol must achieve a state of long-term readiness where core developers could theoretically step away.

In an X post on Jan. 12, Buterin outlined seven specific technical requirements that would allow the blockchain to ossify, with pre-emptive quantum-resistance cited as a non-negotiable priority for century-long security.

“We should resist the trap of saying 'let's delay quantum-resistance until the last possible moment in the name of eking out more efficiencies for a while longer.' Individual users have that right, but the protocol should not. Being able to say 'Ethereum's protocol, as it stands today, is cryptographically safe for a hundred years' is something we should strive to get to as soon as possible, and insist on as a point of pride,” Buterin wrote in the post.

Buterin’s emphasis on quantum resistance echoes growing interest in post-quantum security across the Ethereum ecosystem. In March 2025, the Ethereum Foundation backed ZKNox, a startup aiming to develop open-source code that improves Ethereum security and efficiency, with a special focus on post-quantum cryptography.

Beyond quantum resistance, Buterin’s post listed six other pillars required for protocol ossification. These include an architecture capable of scaling to thousands of transactions per second using ZK-EVM validation and PeerDAS, and a state management system durable for decades via statelessness and state expiry.

The Ethereum co-founder also called for a fully abstracted account model moving beyond ECDSA, a denial-of-service-resistant gas schedule, a refined proof-of-stake economic model for long-term decentralization, and a censorship-resistant block-building mechanism.

Buterin emphasized a staged approach, completing at least one requirement per year where feasible, with future changes ideally reflected through parameter adjustments rather than frequent hard forks.
