During this week’s ACDE Call #220, Ethereum core developers discussed a tentative timeline for activating Ethereum’s Fusaka upgrade across testnets. Developers agreed to begin with the Holesky testnet, despite its scheduled deprecation in the coming months. Holesky’s infrastructure will be shut down two weeks after the Fusaka upgrade finalizes. Developers tentatively plan to release updated testnet client versions by September 22, activate Fusaka on Holesky during the week of September 29, proceed with the Sepolia fork in the week of October 13, and complete the rollout on Hoodi two weeks later in the week of October 27. The proposed schedule will be finalized once fork block times are confirmed during the next ACD call. Fusaka is Ethereum’s next upgrade, slated for Q4 2025 that will introduce scaling improvements through PeerDAS, an enhancement that allows nodes to verify blob data availability without downloading the entire dataset, increasing data capacity and significantly reducing costs for Ethereum rollups.

The Reth team released a postmortem on last week’s incident that caused some Reth nodes to stall due to a state root mismatch. The issue stemmed from a bug in Reth’s trie update handling, which introduced corrupted storage data during a reorg nearly 200k blocks earlier. The problem only surfaced until block 23272427. A fix and database repair tool were shipped in Reth v1.7.0. The bug was limited to Ethereum mainnet Reth nodes and did not affect OP Reth or nodes on other networks.

Scroll, an EVM-equivalent ZK Rollup, announced a pause on new governance proposals within its DAO while it works on redesigning its governance framework. According to delegate Olimpio, Scroll DAO leadership resigned earlier this week. The team will move forward with all previously approved governance proposals. The Scroll team stated that the new governance model aims to enhance efficiency, clarity, and alignment. In response to the uncertainty, the Aave Chan Initiative (ACI) submitted a proposal to adjust risk parameters for assets on the Aave V3 Scroll instance, including raising reserve factors to 50%.
