Coin Bureau covered a controversial research report claiming Ethereum’s December 2025 Fusaka upgrade may have unintentionally created serious problems for the network.
Key Points
-
The Fusaka upgrade doubled Ethereum’s gas limit, aiming to improve scalability and reduce fees.
-
Instead of dropping slightly, transaction fees collapsed by over 90%, far more than expected.
-
Lower fees made address poisoning attacks much cheaper, allowing scammers to flood the network with fake transactions designed to trick users.
-
According to the report, dust or poisoning transactions now make up a large share of Ethereum activity, inflating metrics like wallet growth and transaction counts.
-
Because fees are so low, ETH burn has fallen and validator rewards have dropped, weakening Ethereum’s tokenomics and staking incentives.
-
Critics argue this could reduce network security and make Ethereum less attractive to institutions.
-
However, Ethereum still dominates DeFi, stablecoins, and tokenized real-world assets, which keeps it central to the crypto ecosystem.
-
Developers are already working on the Glamsterdam upgrade, which aims to further improve scalability and network efficiency.
Final Takeaway
The report argues Fusaka created unexpected side effects that weakened Ethereum’s tokenomics and increased spam attacks. Still, Ethereum’s strong ecosystem and ongoing development suggest the issues could be temporary if the network adapts.
