Catenaa, Friday, December 05, 2025- Ethereum’s upcoming Fusaka upgrade may shift economic incentives from Layer-2 networks back to ETH, potentially increasing staker rewards and fee burns while strengthening base-layer integration.

The upgrade introduces infrastructure for “based rollups,” allowing Ethereum validators to sequence L2 transactions instead of relying on independent operators.

Currently, most revenue from rollups, including MEV extraction, sequencing fees, and transaction ordering, remains at the L2 level.

Nansen research analysts note that Fusaka could redirect these flows to ETH stakers if rollups adopt the model, increasing validator earnings and boosting the network’s economic alignment.

The change is not automatic; L2 teams must modify sequencing practices to capture these benefits.

Fusaka also enhances network throughput, lowering costs for L2 blob transactions by up to eight times and improving predictability for validators.

Experts say this could attract institutional participation by providing a more stable environment for tokenized assets, settlements, and regulated financial operations.

Lower fees and higher throughput may streamline real-world asset transfers and reduce operational risk for market participants.

The upgrade is expected to expand the validator base by reducing technical barriers, improving decentralization, and limiting concentration risks.

Analysts emphasize that broader adoption of the base-rollup model will be key to determining whether Ethereum can capture a larger share of economic activity previously siloed on L2 networks.

As Fusaka rolls out, the Ethereum community will monitor L2 integration decisions closely, with potential implications for staking economics, fee structures, and institutional adoption across the ecosystem.
