In this episode of Unchained, guest host Christine Kim interviews Preston Van Loon about the upcoming Ethereum Fusaka upgrade and its impact, particularly on Layer 2 (L2) solutions. They discuss the key features of Fusaka, including PeerDAS for data scaling, the increase in block size, and EIPs for improved user experience like passkey integration. Van Loon explains how PeerDAS uses erasure coding to scale the data layer without increasing hardware requirements for node operators, and how the upgrade will incrementally increase blob capacity through blob parameter-only upgrades. They also address concerns about L2 readiness, the importance of backfilling, and the semi-super node feature for retaining data. Van Loon expresses cautious optimism about the upgrade, highlighting the extensive testing and community involvement, while Kim provides context and asks about potential risks and preparations for the mainnet activation.
