On December 3, 2025, the Ethereum network underwent a significant upgrade with the activation of the Shanghai hard fork. This update introduces a groundbreaking mechanism known as Peer Data Availability Sampling (PeerDAS), which is set to transform the network's scalability and efficiency, as enthusiastically stated in the publication.
Shanghai Hard Fork Overview
The Shanghai hard fork aims to enhance data availability and throughput, which are critical factors for the growing Layer 2 ecosystem on Ethereum. By implementing PeerDAS, the upgrade allows for a more robust infrastructure that can support increased transaction volumes and user activity.
Optimism Among Developers and Analysts
Developers and analysts are optimistic about this advancement, viewing it as a pivotal moment in Ethereum's journey towards achieving the long-sought scalability. With the Shanghai upgrade, Ethereum is poised to better accommodate the demands of its expanding user base and decentralized applications.
On January 19, 2026, Ripple announced a collaboration with UC Berkeley to launch the University Digital Asset Xcelerator (UDAX), aimed at enhancing real-world applications on the XRP Ledger. This initiative contrasts with Ethereum's recent Shanghai upgrade, focusing on different aspects of blockchain development. For more details, see read more.
