Earlier, the upgrade was successfully deployed on Holesky and Sepolia.

The implementation of Fusaka is planned in three stages. Following the mainnet activation on December 17th, developers will launch an EIP to increase the capacity of BLOB objects. The second stage will begin on January 7th, focusing on further expanding their capacity.

Subsequently, experts will concentrate on the next hard fork Glamsterdam, which is also part of The Surge phase in the Ethereum technical roadmap.

What Will Fusaka Bring?

The upgrade aims to implement fundamental improvements to enhance the scalability, efficiency, and security of the second-largest cryptocurrency network by market capitalization.

Fusaka will implement over 10 EIPs in total. The key one is EIP-7594, which will introduce the PeerDAS protocol to Ethereum. This technology will allow validators to verify small fragments instead of entire BLOB objects, increasing data availability for the entire ecosystem.

Project co-founder Vitalik Buterin described this approach as unique and stated that PeerDAS is the “key to scaling” the L2 ecosystem.

Fusaka also proposes more than doubling the gas limit at the first level, which should significantly increase the network’s throughput. As noted by user Leo Lanza, after Fusaka, transaction processing speed will reach 12,000 TPS.

Other important improvements include:

• EIP-7825: sets a gas limit of 30 million per transaction to enhance reliability and prevent Ethereum network overload due to resource-intensive operations;
• EIP-7939 and EIP-7951: will improve performance and expand the capabilities of ZK solutions.

Ethereum Price

At the time of writing, the second-largest cryptocurrency by market capitalization is trading around $4,000. Its price has decreased by 1.9% over the past 24 hours.

Analysts at VanEck believe that Fusaka will have a significant impact on Ethereum. They state that the upgrade will “strengthen the monetary properties of the cryptocurrency” through several key mechanisms:

• reducing fees in L2 will revitalize the ecosystem, increasing the value of the base token;
• increased economic activity will boost demand for the coin as a collateral asset;
• enhanced security of the L1 network will make ETH a more attractive store of value.

“A new investment logic is forming: Ethereum is gradually transforming from an asset that generates income through fees into a full-fledged currency,” the experts emphasized.

Some community members anticipate that the upgrade will push the leading altcoin to $10,000 in the current cycle. Analysts at XWIN Research and BitMine chairman Tom Lee share this forecast.
