According to the source, Ethereum price reportedly swelled as a 'Fusaka' upgrade went live, but this upgrade name is not among prior Ethereum hard forks (e.g., Shanghai, Dencun) documented by the Ethereum Foundation, so traders should seek confirmation from official Ethereum client teams or the Ethereum Foundation before acting. According to the source, until verified, focus on three checks to avoid headline risk: confirm upgrade activation via official announcements or client release notes, watch ETH spot volume versus perpetual funding rates and open interest for confirmation of trend strength, and assess options implied volatility and skew for signs of sustained directional positioning.

According to @pedrouid, the Fusaka upgrade is scheduled in about one hour with a final countdown to Ethereum slot 13,164,544, and traders can monitor progress on Etherscan Blocks to confirm the exact trigger slot for timing trades and on-chain activity (Source: @pedrouid; Source: Etherscan). No additional technical details or market impact guidance were provided in the announcement, indicating this update serves primarily as timing confirmation and a tracking reference for traders (Source: @pedrouid).

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.
