Solana Labs CEO questions Vitalik Buterin’s long-term blockchain thesis

Solana co-founder Anatoly Yakovenko has challenged Ethereum founder Vitalik Buterin’s vision for blockchain protocol development.
Summary

• Yakovenko says Solana must keep iterating and warns stagnation kills protocols.
• Vitalik argues Ethereum should function long-term without mandatory upgrades.
• The debate contrasts perpetual innovation with resilience through ossification.

Yakovenko argues that Solana must continue iterating indefinitely, warning that any protocol stopping its evolution to meet developer and user demands will “die.”

The exchange began when Yakovenko responded to Buterin’s post about Ethereum passing the “walkaway test.” Buterin advocates for reaching a state where Ethereum can ossify, meaning the protocol could theoretically stop receiving updates while maintaining its core value.

I actually think fairly differently on this. Solana needs to never stop iterating. It shouldn’t depend on any single group or individual to do so, but if it ever stops changing to fit the needs of its devs and users, it will die.

It needs to be so materially useful to humans… https://t.co/itqr1b5az4

Yakovenko counters that continuous adaptation is necessary for survival, though Solana shouldn’t depend on any single organization to drive these changes.

Yakovenko’s vision for continuous Solana evolution

Yakovenko stated that Solana’s future depends on remaining “materially useful to humans” with enough active developers earning from the network’s transactions.

He envisions these developers having spare resources to contribute protocol improvements back to the open-source project.

The Solana co-founder shared a selective approach to protocol changes. While he advocates for constant iteration, he said the network must reject most proposed changes.

Upgrades should target real problems facing developers and users rather than attempting to satisfy every request.

Yakovenko predicts Solana will have future versions built by contributors outside the current core teams at Anza, Solana Labs, or Firedancer.

He suggested the ecosystem could transition toward a model where governance votes fund the computational resources needed to write new code.

Vitalik’s case for protocol ossification

Buterin argues Ethereum must support trustless and trust-minimized applications across finance, governance, and other sectors. He compares these to tools like hammers.

The Ethereum founder contends that applications can’t achieve true trustlessness if built on a base layer requiring ongoing vendor updates.

He frames this as Ethereum needing to embody the same traits it enables for applications built on top of it.

Buterin clarified that reaching ossification capability doesn’t mean halting all protocol development. Rather, Ethereum’s value proposition shouldn’t strictly depend on features not yet implemented.

The network should reach a baseline where it can function indefinitely without mandatory upgrades.
