Buterin Wants to Gut Ethereum's Execution Layer
Ethereum co-founder lays out a two-phase plan to replace the chain's core execution infrastructure.
Vitalik Buterin just dropped a blueprint for ripping out and rebuilding Ethereum's execution layer. The plan is ambitious, sweeping, and comes in two parts.
Phase one: swap in a binary state tree. This would replace the existing data structure underpinning how Ethereum stores and accesses network state. Binary trees are simpler, more efficient, and better suited for the cryptographic proof systems Ethereum increasingly relies on.
Phase two is the big swing — moving beyond the Ethereum Virtual Machine entirely. The EVM has been Ethereum's computational backbone since launch, but Buterin argues the chain needs something fundamentally better to hit its long-term performance and scalability targets.
No specific timelines were given. But the detailed technical case signals this isn't idle brainstorming — it's a roadmap. Ethereum developers now have their marching orders for the next major architectural shift.
