Just one week after the successful Pectra upgrade, Ethereum announced plans for Fusaka – an update promising to reduce costs and optimize Layer-2. But with a history of delays, will Fusaka launch on time? Let's analyze in detail.


Fusaka: A New Step Forward After Pectra

After The Merge, Dencun, and Pectra, Ethereum continues with #Fusaka – a major upgrade expected by the end of 2025, focusing on improving scalability and reducing costs. Recently, Pectra has enhanced organizational staking, improved wallets, and increased transaction performance. Fusaka will continue, prioritizing blob data support and reducing network load, especially for Layer-2 (L2) solutions like Arbitrum, Optimism, Base.


The highlight of Fusaka is EIP PeerDAS (Peer Data Availability Sampling), allowing validators to only download a portion of 'blob' data instead of the whole, reducing gas costs and increasing availability verification efficiency. 'Blob,' introduced through EIP-4844 in Dencun, is temporary off-chain storage space for L2 transactions. Expanding the blob limit will help L2 operate more efficiently while reducing the burden on validators.


History of Delays: Major Challenges

Ethereum is famous for its upgrade delays:


  • Pectra: Expected late 2024 after the Mekong testnet, but continuous errors have pushed deployment on Holesky and Sepolia to Q1/2025, finally launching in early May 2025.


  • Dencun: Initially scheduled for 2023, after many failed tests, officially launching in mid-March 2024.



These delays have led to criticism of the Ethereum Foundation for being 'out of breath,' slowing progress in the face of the rapidly changing crypto industry. Some opinions suggest that this nonprofit organization operates slowly, causing developers to shift to other ecosystems and the price $ETH to lag.


Market Reaction: ETH Rises 40% After Pectra

Despite criticism, ETH surged 40% in the 7 days following Pectra (currently at $2,500, according to market data), somewhat soothing the community. This growth indicates confidence in long-term upgrades, but the pressure of expectations for Fusaka remains high. If delays continue, Ethereum may lose its competitive edge against blockchains like $SOL or new ecosystems.


Impact on the Crypto Market

This event brings many signals:



  • Increasing confidence: Crypto fund inflows reached $3.4 billion last week, Bitcoin ETF attracted $1.8 billion, forecasting an accumulation of $330 billion into Bitcoin by 2029.


  • Boosting L2: Fusaka could reduce fees for Arbitrum, Optimism, Base, increasing the appeal of the Ethereum ecosystem.




Future Prospects

If Fusaka launches on time by the end of 2025, L2 transaction fees could significantly decrease in the next 1-2 years, reinforcing Ethereum's position against competitors. However, with a history of delays, the community needs to prepare for the possibility of a postponement to 2026. ETH prices could continue to rise if confidence is maintained, but any failure could exert downward pressure.


Conclusion: Will Fusaka Take Ethereum to New Heights or Continue to Delay?

Fusaka promises to reduce costs and optimize Layer-2 for Ethereum, following Pectra's success that caused ETH to rise 40% in a week. However, the history of delays from Dencun to Pectra raises questions about the ability to launch on time by the end of 2025. With great potential but also many challenges, investors should watch closely to seize opportunities or avoid risks.
