Ethereum Foundation details the November "Fusaka" upgrade: introducing PeerDAS to increase DA access capacity by eight times.

Ethereum announced the launch of the "Fusaka" upgrade in November, introducing PeerDAS technology, which increases data throughput by 8 times, opening up expansion windows for Layer 2 applications and preparing Ethereum for integration with large financial settlement public chains. (Background: Ethereum's push towards $4,800: market capitalization surpassing $580 billion, exceeding Netflix and Mastercard) (Supplementary background: Ethereum's McDonald's moment: How Rollups became the franchising model of Web3?) The Ethereum Foundation confirmed on August 22 in "Protocol Update 002" that the network upgrade codenamed "Fusaka" will start in November this year. The upgrade focuses on introducing "data availability sampling" (PeerDAS) technology to Ethereum, planning to expand the number of blobs that each block can carry from about 6 to more than 48, which equates to increasing data throughput from 64KB/s to 512KB/s, directly addressing the data availability bottleneck that plagues Layer 2 (L2). The key L2 scaling solution of PeerDAS requires transaction data to be submitted to Layer 1 (L1) for verification, but currently L1 has only a limited capacity for blobs per block, leading to high scaling costs and easily soaring gas fees. PeerDAS allows nodes to verify the legality of blocks without downloading the complete data through random sampling, thus safely increasing the number of blobs without sacrificing decentralization and security. The official goal is to achieve an 8-fold increase first, then gradually adjust parameters according to network load, releasing more space for real-time payments, on-chain games, and AI applications. The upgrade roadmap for Fusaka is not a one-time fix. After the upgrade, Ethereum will introduce "Blob Parameter Only" (BPO), a hard fork that only modifies parameters, which will automatically fine-tune the blob limits based on network conditions through proposals like EIP-7892, ensuring stability and flexibility. Ethereum's next step is scheduled for 2026 with the Glamsterdam upgrade, which will deploy PeerDAS v2, pipeline improvements under EIP-7732, and raise the block gas limit from 45 million to 150 million, further amplifying L1 processing capacity. To reduce the occurrence of gas wars, Ethereum is evaluating linking the base cost of blobs with execution costs and studying a dual-variable EIP-1559 mechanism; simultaneously, maintaining censorship resistance through Mempool Sharding to ensure fairness among nodes. In the long term, Ethereum's upgrade steps indicate that FullDAS and "Danksharding" research are still ongoing, aiming to establish Ethereum as a solid foundation for the global "settlement layer."
