Ethereum News Today: Ethereum’s Fusaka Update: Achieving Greater Scalability While Maintaining Security

Ethereum’s eagerly awaited Fusaka upgrade is scheduled for release on December 3, following its successful completion of the final trial on the Hoodi testnet. This milestone marks a significant move forward in Ethereum’s ongoing efforts to boost both scalability and security.

. The update brings in features such as PeerDAS, higher gas limits, and steps toward parallel execution of smart contracts. Developers have called this a major leap for the network’s ability to accommodate increasing usage, . With Ethereum trading close to $4,200, the upgrade comes at a time when the market is mixed, balancing about technical progress with ongoing crypto market fluctuations, especially as .

The Fusaka upgrade incorporates

Improvement Proposals (EIPs) like EIP-7594, which introduces Peer Data Availability Sampling (PeerDAS). This advancement enables validators to check smaller pieces of data from peers instead of downloading entire blobs, greatly lowering bandwidth and storage needs as the upgrade . By making data sampling more efficient, PeerDAS boosts node performance and enhances security for Layer 2 solutions—key for scaling Ethereum’s transaction capacity—demonstrating the . The upgrade also from 30 million to 150 million units, which could double the network’s ability to handle transactions and data blobs.

The rollout will be executed in three stages: first, activating Fusaka on the mainnet; second, expanding blob capacity to support more Layer 2 transactions; and third, a hard fork to further raise data limits, as previously covered by Yahoo. This phased rollout is designed to ensure a smooth transition for both validators and developers.

, after Fusaka, the Ethereum community will turn its attention to the next major update, Glamsterdam, which seeks to improve block times and introduce enshrined proposer-builder separation as part of the larger “Surge” roadmap.

Developers highlight that Fusaka tackles one of Ethereum’s fundamental issues—the blockchain trilemma—by enhancing scalability while maintaining both decentralization and security, as noted in recent analyses. While rival blockchains like

have focused on speed, Ethereum’s step-by-step upgrades are intended to close this gap while preserving its leadership as the top smart contract platform. The update also supports the rising interest in zero-knowledge (ZK) rollups, which depend on efficient data availability to lower costs and improve privacy.

Key teams such as Nethermind confirmed that the Fusaka testnet deployment on Hoodi went smoothly, boosting confidence in the December 3 launch. This follows earlier successful tests on the Holesky and Sepolia testnets in October, with Ethereum Foundation leaders emphasizing the importance of coordinated efforts to meet the deadline. The timing of the upgrade also aligns with broader market trends, including a $360 million oversubscribed token sale for MegaETH, a Layer 2 project built on Ethereum’s infrastructure.

Some critics point out that while Fusaka makes Ethereum more efficient, the platform still faces competition from newer blockchains and must navigate global economic challenges. Supporters, however, believe the upgrade’s focus on Layer 2 compatibility and data efficiency will help Ethereum maintain its dominance in decentralized finance (DeFi) and enterprise use, according to industry experts. As the December 3 launch nears, the community is closely watching how the upgrade will affect gas costs, transaction speeds, and the wider crypto landscape.
