Ethereum Today News: Fusaka upgrade successfully activated on the final Testnet, Mainnet roadmap revealed.

The important Fusaka upgrade for Ethereum was successfully activated on the final Testnet Hoodi on October 28, marking the countdown to the Mainnet deployment. According to the developer's plan, the Fusaka upgrade will be rolled out in three phases, with core protocol changes tentatively scheduled to start on December 3, aiming to significantly optimize the transaction cost and data throughput of the Layer-2 (L2) network by increasing Blob capacity in stages. Despite significant progress in network development, the price of Ethereum (ETH) fell below the $4,000 mark after the news was released due to macroeconomic uncertainty, and market sentiment remains cautious.

Fusaka Upgrade Final Testing Completed: Mainnet Deployment Enters Critical Countdown

Ethereum's scalability journey has once again taken a solid step forward. The Ethereum execution client Nethermind team has confirmed that the Hoodi Testnet hard fork was “successfully completed” on October 28, setting a key milestone for the upcoming Fusaka upgrade Mainnet launch. Prior to this, the Fusaka upgrade had been successfully deployed and validated on the Sepolia and Holesky Testnets. Hoodi, as the final testing phase before the Mainnet launch, its successful activation means that the development team is ready for the official launch in December.

The Fusaka upgrade is a direct follow-up to the Pectra upgrade that went live on the Mainnet in May of this year. The Pectra upgrade introduced EIP-7702 to implement account abstraction and moderately increased Blob capacity, effectively reducing L2 Transaction Cost and improving data throughput. Building on this, Fusaka will continue to focus on the data availability and scalability of Ethereum.

Key Technology Interpretation: Enhancing Blob Capacity and Introducing PeerDAS

The core of the Fusaka upgrade lies in addressing Ethereum's data availability and scalability bottlenecks. Developers plan to gradually increase the network's Blob capacity by introducing the Blob Parameter Only (BPO) fork in phases. Blobs are a structure used for efficiently submitting data from L2 Rollup to the Ethereum Mainnet, and increasing their capacity is key to reducing L2 fees and enhancing the overall scalability of the network.

In addition to the BPO fork, Fusaka will also bring several key technological changes, including:

1. EIP-7594 (Peer Data Availability Sampling - PeerDAS): This feature aims to improve the way nodes access L2 data. By allowing validators to check only data fragments instead of the complete Blob, PeerDAS can alleviate bandwidth pressure while reducing the operating costs for validators and the L2 network.
2. Verkle Trees (: The introduction of Verkle Trees will help achieve more compact state proofs, thereby reducing the amount of data required for node operation, which is expected to improve the degree of decentralization and synchronization speed of the network.
3. Increase in Block Gas Limit: Moderately raising the block gas limit is expected to enhance the transaction throughput of the Ethereum base layer (Layer-1).

These technical upgrades collectively form the core support for the Fusaka upgrade's expansion goals for the next phase of Ethereum.

Fusaka Mainnet Roadmap Revealed: Gradual Expansion in Three Phases

According to the plan released by the developers, the Fusaka upgrade will be launched in three phases on the Mainnet to ensure a smooth transition and risk control:

This phased rollout strategy indicates that the developers place a high emphasis on network stability while pursuing performance improvements.

Ethereum (ETH) Price Under Short-term Pressure Ahead of Upgrade

Despite the successful testing of the Fusaka upgrade injecting confidence into the long-term development of Ethereum, the price of Ethereum has experienced a pullback in the short term. On the same day the testing was completed, the price of Ethereum began a downward correction from a high of $4,252, falling below $4,000 and losing the 100-hour simple moving average.

Technical indicators show that the hourly MACD has entered a bearish zone, and the RSI has fallen below the 50 area, indicating a weakening short-term bullish sentiment. Analysts point out that macro-level uncertainties, especially the impact of the Federal Open Market Committee (FOMC) meeting on interest rate decisions, have put volatility and selling pressure on risk assets, including Ethereum. In the short term, if the price of Ethereum fails to hold the key support level of $3,920 (close to the 61.8% Fibonacci retracement level of the recent upward wave), it may further dip to $3,880 or even lower. Investors should remain vigilant about short-term technical and macroeconomic risks while paying attention to favorable network upgrades.

Conclusion

The successful launch of the Ethereum Fusaka upgrade on the Testnet undoubtedly solidifies Ethereum's position as an industry infrastructure. Its focus on L2 scaling and data efficiency signals the arrival of a lower-cost, higher-performance ecosystem. In the long run, the development of network technology is the core driving force supporting Ethereum's value, but in the short term, the price trend of Ethereum remains full of uncertainties due to market sentiment and macroeconomic influences. Investors should closely monitor the progress of the Mainnet launch in early December and cautiously assess risks in conjunction with the broader market environment.
