According to @VitalikButerin, Fusaka prioritizes safety and centers on PeerDAS to enable a live blockchain where no single node must download full block data, a design aimed at robust data availability for scaling. source: Vitalik Buterin on X, Sep 24, 2025. He explained that PeerDAS has each node request a small number of chunks to probabilistically verify that more than 50 percent of chunks are available, after which nodes can download those chunks and use erasure coding to recover the rest. source: Vitalik Buterin on X, Sep 24, 2025. In the first version, full block data must still exist in one place for initial broadcasting and for reconstruction when a publisher releases between 50 percent and less than 100 percent of a block, but these roles are untrusted and require only one honest actor to succeed even if many are dishonest. source: Vitalik Buterin on X, Sep 24, 2025. He added that future cell-level messaging and distributed block building will distribute even these remaining functions. source: Vitalik Buterin on X, Sep 24, 2025. Core developers will be highly cautious on testing, and the blob count will increase conservatively at first before becoming more aggressive over time. source: Vitalik Buterin on X, Sep 24, 2025. He stated PeerDAS is key to L2 scaling and eventually L1 scaling once the L1 gas limit is high enough to place L1 execution data into blobs, framing Fusaka and PeerDAS as central to Ethereum’s scaling roadmap. source: Vitalik Buterin on X, Sep 24, 2025.

According to @alice_und_bob, Layer 2 (L2) teams can address common scaling and security challenges—such as the need for zk proofs, fraud proofs, 7-day exit windows, and alternative data availability bridges—by utilizing Polkadot core technology instead of more complex or resource-intensive solutions. This highlights Polkadot’s (DOT) potential as a scalable, cost-effective platform for developers, which could increase demand for DOT and impact its price performance in the crypto market.

According to Vitalik Buterin, the most effective way to build a Layer 2 (L2) network is to heavily rely on the Layer 1 (L1) for core functionalities such as security, censorship resistance, and data availability. In his view, the L2's logic should be reduced to simply being a sequencer and a prover, or only a prover for 'based' rollups that use the L1 for sequencing. This vision implies that L2s with deeper integration into the L1's security model may be viewed more favorably, a key consideration for traders evaluating the long-term viability and potential valuation of various L2 ecosystem tokens and the core value proposition of Ethereum (ETH) as the ultimate settlement layer.

According to jesse.base.eth (Jesse Pollak) on Twitter, the shift of companies moving onchain is expected to become as routine as creating websites, signaling a major trend in blockchain adoption (source: Twitter, June 17, 2025). For crypto traders, this suggests increased demand for blockchain infrastructure tokens like ETH and L2 scaling solutions, as enterprise onchain activity typically drives transaction volume and long-term network value. Monitoring enterprise blockchain adoption rates could provide early signals for price movements in related cryptocurrencies.

According to robmsolomon on Twitter, the post highlights the practical aspects of L1 and L2 blockchain integration for app developers, emphasizing the importance of supporting both layers for improved scalability and lower transaction fees. This dual-layer approach is essential for crypto trading platforms aiming to offer users faster settlement times and reduced costs, directly impacting trading efficiency and user retention in the competitive DeFi market (source: robmsolomon on Twitter, May 13, 2025).
