Scalability
Ethereum’s second BPO hard fork increased the blob limit from 15 to 21, boosting block data capacity to roughly 2.6 MB. The update aims to ease data constraints for rollups and other calldata-heavy applications.
Polygon (MATIC) activated the Madhugiri hardfork on Dec. 9, 2025, introducing protocol-level optimizations that boost transaction speed and overall throughput. The upgrade is aimed at improving scalability and strengthening Polygon's appeal for enterprise-grade blockchain deployments.
The Ethereum Foundation has proposed the Ethereum Interop Layer (EIL) to reduce fragmentation across Layer 2 networks, aiming to improve cross-rollup communication and lower friction as throughput and adoption climb.
Ethereum recorded an all-time high of 24,192 transactions per second (TPS), analyst Joseph Young reports. The milestone highlights improving throughput for the network.
Ethereum plans to activate the Fusaka upgrade on December 3, 2025, aiming to tackle long-standing scalability constraints. The change is designed to boost capacity for rollups and dapps, potentially easing congestion and lowering effective fees.
Ethereum will activate the Fusaka Upgrade on December 3, 2025 to tackle scalability and improve how the network handles transactions and Layer-2 settlement. Developers say the protocol-level changes tested on public testnets could materially improve throughput and fees if successful.
Ethereum is preparing to launch its Fusaka upgrade on December 3, 2025, introducing PeerDAS to enhance scalability and reduce costs. After successful tests on Holesky, Sepolia, and Hoodi testnets, the upgrade aims to improve user and developer experience, with a follow-up hard fork named Glamsterdam in development.
The Ethereum Fusaka Hard Fork, launching on December 3, 2025, introduces major improvements including 12 new EIPs, enhanced blob capacity, and heightened security to boost network scalability and reduce costs. This upgrade follows the Pectra update and includes an extensive public testing phase and a $2 million code audit program by the Ethereum Foundation.
