According to Vitalik Buterin, Ethereum's gas limit increased from 30M to 60M in 2025, significantly enhancing transaction capacity. Additionally, the introduction of PeerDAS provided substantial scalability improvements for Layer 2 (L2) solutions and future Ethereum L1 data blob storage. These advancements mark a pivotal step towards further optimizing Ethereum's infrastructure.

According to the source, Vitalik Buterin said Ethereum is nearing a turning point with PeerDAS data availability sampling now live and zkEVMs in the alpha stage, describing a fundamentally new decentralized network design that can solve the blockchain trilemma.

For trading, these scaling milestones indicate lower data costs for Layer 2 rollups and higher throughput, dynamics that previously coincided with fee compression and increased L2 activity after the Dencun upgrade introduced EIP-4844.

Traders should monitor ETH spot and perpetual funding, L2 transaction counts, rollup fees, and gas consumption across zkEVM ecosystems as the market prices in the Ethereum scaling roadmap with PeerDAS.

According to @Tetranode, Vitalik Buterin says Ethereum’s combination of PeerDAS on mainnet and ZK-EVMs at alpha with production-quality performance means the scalability trilemma is solved with live running code, while safety work remains for ZK-EVMs; he expects small portions of the network to use ZK-EVMs in 2026.

Vitalik states PeerDAS is already live on mainnet and ZK-EVMs are production-quality on performance today, with the trilemma solution emerging from these components; he frames this as a fundamental shift to a decentralized, consensus-enabled, high-bandwidth network. Source: x.com/VitalikButerin/status/2007559523528233041. He outlines a rollout timeline: in 2026, non-ZK-EVM-dependent gas limit increases driven by BALs and ePBS with first opportunities to run a ZK-EVM node; in 2026–28, gas repricings, state structure changes, and execution payload moving into blobs; in 2027–30, further large gas limit increases as ZK-EVMs become the primary way to validate blocks.

For context, he contrasts previous p2p paradigms—BitTorrent (high bandwidth, decentralized, no consensus) and Bitcoin (decentralized with consensus but low bandwidth due to replication)—with Ethereum’s intended decentralized, consensus, high-bandwidth design under PeerDAS and ZK-EVMs. Source: x.com/VitalikButerin/status/2007559523528233041. Vitalik also highlights distributed block building, aiming to minimize centralized interference in transaction inclusion and improve geographical fairness through in-protocol or marketplace-based mechanisms.

According to @VitalikButerin, PeerDAS is live on Ethereum mainnet and ZK-EVMs are at alpha with production-quality performance while safety work remains, positioning Ethereum for decentralized consensus with high bandwidth.

According to @VitalikButerin, the Ethereum Foundation historically emphasized cryptoeconomics, BFT consensus, and blocks while underweighting the p2p networking layer (source: @VitalikButerin, X, Dec 8, 2025). According to @VitalikButerin, that gap has closed and PeerDAS is evidence of improved p2p capabilities on the ETH network (source: @VitalikButerin, X, Dec 8, 2025). According to @VitalikButerin, he credited @raulvk and others for contributing to PeerDAS and the networking work (source: @VitalikButerin, X, Dec 8, 2025).

According to Binance Research, Ethereum has completed the Fusaka hard fork and deployed Peer Data Availability Sampling (PeerDAS). According to Binance Research, the upgrade is estimated to cut Layer-2 transaction fees by 40% to 60%. According to Binance Research, the change enables the L2 ecosystem to target over 100,000 transactions per second.

According to @VitalikButerin, PeerDAS in Fusaka literally is sharding, allowing Ethereum to reach consensus on blocks without any single node seeing more than a tiny fraction of the data (source: Vitalik Buterin on X, Dec 3, 2025). He adds the design is robust to 51% attacks through client-side probabilistic verification (source: Vitalik Buterin on X, Dec 3, 2025). He characterizes this as a significant development for Ethereum (ETH) (source: Vitalik Buterin on X, Dec 3, 2025).

According to @BullTheoryio, the Ethereum Fusaka upgrade will go live today and combines Osaka, Fulu, and PeerDAS, positioning it as a major network release relevant to traders. According to @BullTheoryio, the upgrade could spark ETH’s next supply crunch and is framed as a material change for ETH, with PeerDAS integration cited as a key catalyst for the shift in supply dynamics.
