Vitalik L2 Debate Heats Up
A recent Vitalik-led post restarted debate on L1 vs L2 scaling and product-market fit, with commentators saying L2s now blend Ethereum security with customizability for institutions like Robinhood, Coinbase and Kraken []. Analysts warn L2s improve UX but strip value capture from L1, and one prediction says ~80% of L2s will use dedicated data-availability layers by 2026 — potentially making transactions ~8,000x cheaper than L1 and forcing validator upgrades [][].
Vitalik posted) on Feb. 3, 2026 that the original “rollup‑centric roadmap” “no longer makes sense,” arguing L1 scaling progress has outpaced decentralization on many L2 projects. Robinhood launched) a public Arbitrum‑based testnet for its Robinhood Chain at Consensus Hong Kong on Feb. 10–11, 2026; Coinbase still incubates) its Base network on the OP Stack inside Coinbase, and Kraken’s Ink L2 reported TVL growth from about $7M in Oct. 2025 to roughly $450M by early 2026. Data‑availability traffic and tooling are shifting off‑chain: L2BEAT’s DA throughput dashboard now lists Celestia, EigenDA and Ethereum blobs as the top DA destinations for [rollups tracks].l2beat.com Some industry writeups project modular DA could capture roughly 70% of rollup DA market by late 2026, and benchmarking notes NEAR‑style DA can make 100kB of calldata ≈8,000× cheaper than posting the same data on Ethereum blobs.dalayers.com Research and market reports flag economic consequences: The Block’s 2026 L2 outlook documents consolidation around a few dominant L2s (Base, Arbitrum) and warns that fee‑and‑TVL concentration is squeezing L1 revenue capture.theblock.co Ethereum’s Fusaka upgrade (activated Dec. 3, 2025) added PeerDAS to increase blob capacity, but node operators and infrastructure providers say) validators will need software/hardware updates to handle higher DA sampling rates and the new throughput profiles.
