Ethereum To Launch Fusaka Upgrade on Dec 3: Here's All

Ethereum Fusaka Upgrade Confirmed for December 3

The Ethereum network is preparing to launch its major Fusaka upgrade, set on December 3. Core developers have confirmed the milestone after months of anticipation, sparking excitement and enthusiasm within the community. This upgrade aims to enhance scalability, node efficiency, and data availability, further solidifying Ethereum's position in the blockchain space.

Ethereum Fusaka Upgrade Launch Looming

In a recent X post, ETH researcher Christine Kim unveiled details of the much-anticipated Ethereum Fusaka upgrade. According to the announcement, the event is scheduled for December 3, following testnet deployments on Holesky, Sepolia, and Hoodi in October and November. She added that the developers will finalize exact dates, epoch numbers, and timings in the coming days. 

Significantly, the upcoming Fusaka upgrade marks a crucial milestone for Ethereum, building upon the successful Pectra upgrade. This introduces 11 Ethereum Improvement Proposals (EIPs) designed to boost the network's scalability, node stability, and validator performance.

It introduces PeerDAS (EIP-7594), allowing nodes to verify data by sampling small portions rather than downloading the entire content. This enhances network efficiency and paves the way for full danksharding in the future.

After the update, the blob capacity increase will happen in two phases. The first phase, expected around December 17, will boost the capacity to 10/15 target/max numbers. Then, on January 7, 2026, the second phase will further increase the capacity to 14/21 blobs, effectively more than doubling the current capacity. This phased approach aims to enhance Ethereum's scalability and efficiency, according to Christine Kim.

Reportedly, the blob utilization is currently high, averaging over 90% for major rollups like Arbitrum One (99.6%) and OP Mainnet (99.2%), with median fees ranging from $0.49 to $3.05 per MiB. The Fusaka upgrade's BPO forks aim to alleviate this capacity strain by increasing blob limits, enabling sustained throughput without driving up costs for rollups. Ethereum developer community ethPandaOps stated,

“The initial conclusion is that we can go ahead with a Max blob count of 15 for BPO1 [Blob Parameter Only] and Max blob count of 21 for BPO2. There are a total of 5 BPOs planned for Fusaka, so we can ensure mainnet scales a lot — safely.”

ETH Price Dips

Despite this significant announcement, the ETH price saw a notable plummet, dipping by about 5.5% in a week. Despite a 1.2% decline over the past 24 hours, the token has surged by 4.8% over the past month.

This negative trend is clearly visible in the traders’ activity as the trading volume decreased by around 10%, reaching $27.29 billion. However, ETH remains safe at the second spot on CoinMarketCap with a market capitalization of $539.46 billion.
