Joe Lubin sees Ethereum going fully ZK-based in 3-5 years!

Ethereum co-founder Joe Lubin has put a concrete timeline on one of the network's most ambitious long-term goals: a fully zero-knowledge proof-based protocol within three to five years. The statement marks one of the clearest public commitments from a founding figure on ZK as Ethereum's end-state architecture rather than a scaling add-on.

Why it matters

Zero-knowledge proofs allow transactions and computations to be verified cryptographically without revealing the underlying data — combining privacy and scalability in a single primitive. A fully ZK-based Ethereum would mean every layer of the stack, from execution to consensus, is secured and compressed by ZK proofs. That is a qualitatively different network from today's: lower verification costs, stronger privacy guarantees, and a dramatically smaller trust surface for users and institutions alike.

Lubin's framing matters because it signals that the Ethereum Foundation's broader ecosystem is converging on ZK as the unifying upgrade path — not a competing roadmap, but the destination. Projects building ZK rollups, ZK-EVMs, and proof systems today are effectively building the rails for that end-state.

Market impact

For ETH holders, a credible 3-5 year ZK horizon strengthens the long-term investment thesis: a network that can handle institutional-scale throughput with privacy-preserving settlement is a materially stronger competitor to both traditional finance infrastructure and rival L1s. Near-term, the signal is likely to lift sentiment across the ZK ecosystem — tokens and protocols tied to ZK infrastructure stand to benefit from renewed developer and investor attention.
