Ethereum announces the launch of the 'Fusaka' upgrade in November, introducing PeerDAS technology, which increases data throughput by eight times, opening up scalability for Layer 2 applications and preparing Ethereum for integration with large financial settlement public chains. (Background: Ethereum aims for $4,800: Market cap surpasses $580 billion, overtaking Netflix and Mastercard) (Supplementary background: Ethereum's McDonald's moment: How Rollups become the franchise model of Web3?) The Ethereum Foundation confirmed on August 22 that the network upgrade codenamed 'Fusaka' will commence in November this year. The upgrade focuses on introducing 'Data Availability Sampling' (PeerDAS) technology to Ethereum, with plans to expand the number of blobs each block can carry from about 6 to over 48, increasing data throughput from 64KB/second to 512KB/second, directly addressing the data availability bottleneck troubling Layer 2 (L2). PeerDAS, a key L2 scaling solution, requires transaction data to be submitted to Layer 1 (L1) for verification, but currently, L1 only has a limited capacity for blobs per block, leading to high scaling costs and gas fees easily surging. PeerDAS allows nodes to verify block validity without downloading 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 growth first, then gradually adjust parameters based on network load to free up more space for instant 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) hard forks that only modify parameters, automatically fine-tuning the blob limits based on network conditions through proposals like EIP-7892 to ensure stability and flexibility. Ethereum's next step is the Glamsterdam upgrade scheduled for 2026, which will deploy PeerDAS v2, EIP-7732 pipeline improvements, 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 tying the base cost of blobs to execution costs and researching a dual-variable EIP-1559 mechanism; at the same time, it aims to maintain censorship resistance through Mempool Sharding and ensure fairness for nodes. In the long term, Ethereum's upgrade steps indicate that FullDAS and 'Danksharding' research is still ongoing, with the goal of establishing a solid foundation for Ethereum as the global 'settlement layer.'
