Lubin targets 10,000+ TPS, sets 3–5 year timeline for fully ZK Ethereum

Joe Lubin says Ethereum will go fully ZK in 3–5 years. He ties the move to Justin Drake’s “Lean Ethereum,” targeting 10,000+ TPS on L1.

Lubin made the call in a June 10 interview. He said ongoing ZK work will harden L1 and sync L2s for atomic execution and unified liquidity. Source: The Block interview. Summary thread: X post by @cryptounfolded.

Context: Ethereum (ETH) L1 still faces throughput pressure. Source: Coinspeaker coverage.

Lubin frames a “convergence phase.” ZK proving, battle‑tested on L2s, migrates to L1. Goal: synchronous composability, atomic execution, fewer bridges. Source: The Block interview.

Lean Ethereum operationalizes this at L1 with 10k+ TPS. That aims to close the gap with rival L1s. Solana’s Alpenglow upgrade is in validator testing with sub‑second finality as the headline metric. Source: Coinspeaker report on Alpenglow.

On EF structure, Lubin said: “There won’t be a second foundation.” He expects several focused spin‑outs while the EF narrows scope to core components. Source: The Block interview.
