- The upcoming Fusaka upgrade is expected to improve Ethereum‘s efficiency and reduce costs.
- VanEck reports the upgrade will address data availability challenges for rollups.
- The upgrade’s main feature, Peer Data Availability Sampling (PeerDAS), will help validators process transactions with less bandwidth and storage.
- Growing use of layer 2 solutions is leading to higher demand for Ethereum’s data capacity.
- Fusaka may increase Ethereum’s appeal to institutions by cutting transaction costs and strengthening its role as a settlement layer.
The Ethereum network is set to introduce the Fusaka upgrade in December. The upgrade aims to make the blockchain more efficient and lower overall transaction costs, according to analysis from asset manager VanEck.
In its September market recap, VanEck stated Fusaka will tackle the blockchain’s challenge with data availability for rollups—scaling tools that combine many transactions before recording them on Ethereum. The upgrade’s central feature is Peer Data Availability Sampling (PeerDAS). This technology allows validators to check smaller portions of data instead of downloading every transaction in full, effectively lowering bandwidth and storage needs.
VanEck explained this change means Ethereum can safely increase its “blob” capacity—the term for data segments used by rollups—without overloading the network. Demand for these blobs is high, as developers already doubled blob limits earlier this year. According to VanEck, rollup projects like Coinbase’s Base and Worldcoin’s World Chain now contribute about 60% of all rollup data on Ethereum. With more capacity, Fusaka is expected to make rollup operations cheaper and help lower fees for users.
The report noted that more blockchain activity is shifting to rollups rather than the main Ethereum layer, leading to lower base fee revenues. However, VanEck said this shift does not reduce the value of ETH. Instead, it highlights Ethereum’s importance in securing settlement for rollups, supporting ETH’s use as a monetary asset.
Analysts from VanEck also warned users holding unstaked ETH about dilution risk, as more institutions accumulate and stake ETH for rewards. The firm believes the Fusaka upgrade will boost Ethereum’s position in the growing rollup ecosystem and may attract further institutional interest by reducing costs.
VanEck concluded that Fusaka is a significant step in Ethereum’s focus on rollup scaling, while also noting that some technical hurdles remain. The upgrade is regarded as having “significant implications” for both regular users and long-term ETH holders.
