Ethereum Foundation's Co-Director Advocates for Enhanced Collaboration to Achieve Fusaka Upgrade Deadline
The Ethereum network is set to undergo a major upgrade with the Fusaka update, scheduled to go live in Q4 2025. This upgrade promises significant technical enhancements aimed at improving scalability, network resilience, and node efficiency.
The Fusaka upgrade combines two major upgrades—Fulu (consensus layer) and Osaka (execution layer)—and introduces 11 Ethereum Improvement Proposals (EIPs), along with notable new technologies like Peer-to-Peer Data Availability Sampling (PeerDAS) and Verkle Trees.
One of the key EIPs, EIP-7825, imposes a transaction gas limit cap of 16,777,216 units. This cap enhances Ethereum’s resilience to spam and targeted denial-of-service attacks by safeguarding nodes from resource exhaustion and improving network reliability.
PeerDAS, on the other hand, allows nodes and validators to verify shard data availability by downloading only small random samples of blob data instead of the entire shard data. This reduces bandwidth and storage demands, prevents data withholding attacks, and supports scalability of Ethereum’s sharded blockchain.
Verkle Trees, an advanced cryptographic data structure, reduces proof sizes for state data verification. This enables nodes to prove and verify data with smaller proofs, resulting in lower storage requirements and faster node synchronization times.
Other improvements bundled in Fusaka optimize EVM performance, upgrade blob parameter limits, and enhance coordination between the consensus and execution layers.
The Fusaka upgrade builds on the Pectra upgrade, which went live in May 2025 and brought improvements to validators and account abstraction on the Ethereum network.
Recently, the Ether Machine, a project or entity, has added 15,000 ETH to its holdings, increasing Ethereum exposure. This move comes as Ethereum's continuous technological upgrades have fueled a growing trend among corporations to incorporate ETH into their treasury strategies.
At press time, ETH trades at $3,956, up 3.4% in the past 24 hours. The Fusaka upgrade is being prioritized over the Glamsterdam hard fork, which is expected to launch in Q1 or Q2 of 2026.
A recent VanEck report suggested that ETH, rather than Bitcoin (BTC), may become the future's preferred store of value. The success of the Fusaka upgrade could further solidify Ethereum's position in the cryptocurrency market.

The Fusaka upgrade, set to launch in Q4 2025, will introduce new technologies such as PeerDAS and Verkle Trees to the Ethereum network, marking a significant step forward for blockchain technology. With EIP-7825 creating a transaction gas limit cap to enhance network resilience, the Fusaka upgrade promises to unlock Ethereum's potential for scalability and further establish its position as a leading technology in the cryptocurrency market.
