Linea Voyage Waypoint: The Road to Dencun

A Dhaka panel exploring Ethereum's Dencun upgrade, EIP-4844, Layer 2 scalability, lower transaction costs, and what the next phase of Ethereum infrastructure means for builders and decentralized applications

Linea Voyage Waypoint · Road to Dencun — Dhaka · Community event with Leveor · Invited Panel Speaker · Substitute for Prof. Dr. Md Sadek Ferdous · 2024-02-17 · Dhaka, Bangladesh

Invited to join the Dhaka edition of Linea Voyage Waypoint: The Road to Dencun as a panel speaker when Prof. Dr. Md Sadek Ferdous was unable to attend. The discussion brought together engineers and Web3 ecosystem contributors to examine Ethereum's upcoming Dencun upgrade, particularly EIP-4844, and its implications for rollup economics, Layer 2 scalability, data availability, transaction costs, and the developer experience of building decentralized applications.

Topics: Why Ethereum needed the Dencun network upgrade, EIP-4844 and proto-danksharding as a step toward Ethereum's rollup-centric scaling roadmap, How blob transactions change the way Layer 2 networks publish data to Ethereum, Reducing Layer 2 data-availability costs and transaction fees, The impact of Dencun on rollups such as Linea, Scalability trade-offs between Ethereum Layer 1 and Layer 2 networks, How lower transaction costs can improve the usability and adoption of decentralized applications, What protocol-level improvements mean for application developers and Web3 product teams, The relationship between infrastructure evolution, developer experience, and mainstream Web3 adoption
