Ethereum co-founder Vitalik Buterin declared that the network has finally cracked blockchain’s fundamental trilemma through the combination of zero-knowledge Ethereum Virtual Machines and PeerDAS technology now running on mainnet.
The breakthrough marks the culmination of a decade-long technical journey that began with Buterin’s first data availability sampling commit in 2015 and early ZKEVM development around 2020.
“These are not minor improvements; they are shifting Ethereum into being a fundamentally new and more powerful kind of decentralized network,” Buterin wrote in a post on X, describing how the protocol now delivers decentralization, consensus, and high bandwidth simultaneously, a feat previously considered impossible.
Buterin explained that early peer-to-peer networks faced stark limitations, with BitTorrent offering massive bandwidth and decentralization but no consensus mechanism.
At the same time, Bitcoin achieved decentralization and consensus at the cost of extremely low throughput due to replicated rather than distributed work.
Ethereum’s new architecture breaks this pattern by splitting computational work across nodes while maintaining cryptographic verification of all state transitions.
ZKEVMs have achieved production-quality performance, with proving times dropping from 16 minutes to 16 seconds and costs falling 45-fold, with 99% of Ethereum blocks now provable in under 10 seconds on target hardware.
Meanwhile, PeerDAS enables nodes to verify data availability by sampling small portions rather than downloading entire blocks, dramatically expanding throughput without sacrificing decentralization.
The Ethereum Foundation set a security-first roadmap requiring teams to achieve 128-bit provable security by the end of 2026, with intermediate milestones at 100-bit security by May 2026 and mandatory integration with the soundcalc security estimation tool by February.
“If an attacker can forge a proof, they can forge anything: mint tokens from nothing, rewrite state, steal funds,” the foundation warned in December, emphasizing that performance gains cannot compromise cryptographic integrity.
George Kadianakis from the foundation’s cryptography team stressed the importance of securing architectures before they become moving targets.
“Once teams have hit these targets and zkVM architectures stabilize, the formal verification work we’ve been investing in can reach its full potential,” he wrote, noting that recent advances in compact polynomial commitment schemes like WHIR and techniques such as JaggedPCS now make ambitious security targets achievable.
