According to the source, Vitalik Buterin said a proposal called Fusaka will address Ethereum’s blob usage issues and emphasized a safety‑first rollout using PeerDAS so nodes can verify data availability without downloading full blocks; source: the provided social media post dated Sep 25, 2025. PeerDAS enables probabilistic data availability checks by light clients and is designed to increase data throughput for rollups, which the Ethereum Foundation links to lower L2 data costs via the EIP‑4844 blobs rationale; source: Ethereum Research forum discussions on PeerDAS (2023–2024) and Ethereum Foundation EIP‑4844 specification and rationale.

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 @Gajpower, the Ethereum roadmap emphasizes prioritizing core crypto innovations over traditional Web2 software approaches. Key trading-relevant upgrades include the integration of unified binary Merkle structures, RISC-V EVM compatibility, and network-wide SSZfication, all designed to enhance scalability and security. The focus on zero-knowledge proofs (ZKP), delayed execution, and advanced data availability solutions (peerDas and 2D das) is expected to streamline transaction processing and reduce network congestion. For traders, these technology shifts signal potential for increased Ethereum throughput and lower fees, factors that historically correlate with higher ETH price action and greater DeFi ecosystem participation (source: @Gajpower, Twitter, May 17, 2025).

According to Vitalik Buterin, there is a plan to implement Fusaka on Layer 1 with PeerDAS, targeting a 48/72 blob limit. This development is crucial for traders as it may enhance scalability and efficiency in blockchain transactions. The goal is to initiate a Fusaka testnet with these parameters immediately after the Pectra system goes live, which could significantly impact transaction throughput and trading activities on the blockchain.

According to Vitalik Buterin, Fusaka's integration on Layer 1 with PeerDAS and a 48/72 blob target/limit is planned for 2025, with the aim to establish a testnet post-Pectra's launch, suggesting potential scalability improvements and new opportunities for traders.
