Ethereum developers confirmed the Fusaka upgrade schedule during the ACDC #165 call. This includes targeted testnets in October culminating in a mainnet upgrade on December 3, 2025, introducing PeerDAS and key Layer 2 enhancements.

Ethereum Foundation developers and key participants from Prysm and Teku teams are involved. The upgrade focuses on scalability impacting rollup costs and Layer 2 infrastructure. The announcement of the Fusaka schedule led to a brief 3% drop in ETH prices, reflecting investor sensitivity. Layer 2 protocols are expected to see significant benefits from the scalability improvements. scalability
Financial and Market Implications
The financial implications include a $2 million audit program by the Ethereum Foundation for securing Fusaka code. This proactive measure aims to ensure stability prior to the mainnet deployment. The deployment across testnets aims for gradual system stability. Historically, major upgrades like The Merge impacted ETH volatility, suggesting similar market dynamics could arise post-Fusaka.
Historical Context and Expected Outcomes
Historical data from past upgrades shows potential for increased network capacity and reduced fees. The upcoming enhancements could significantly boost Ethereum's throughput, benefiting not just ETH but also Layer 2 tokens.
"Blob capacity should more than double over the two weeks following Fusaka's activation." - Christine Kim, Researcher
