- The Fusaka upgrade will launch on Ethereum‘s mainnet on December 3.
- It includes 12 Ethereum Improvement Proposals (EIPs) to enhance scaling and data handling.
- PeerDAS technology reduces data load for verifying layer 2 transactions, lowering costs and improving scalability.
- The upgrade aims to increase Ethereum’s transaction throughput and support a $47 billion layer 2 ecosystem.
- Fusaka also brings improvements to Ethereum’s base layer by raising block and data limits.
On December 3, the Ethereum blockchain will implement the Fusaka upgrade on its mainnet, according to the Ethereum Foundation. This update aims to address the growing transaction volume from Ethereum’s layer 2 blockchains, which collectively support an on-chain economy valued at $47 billion. Layer 2 chains offer faster, cheaper transactions while relying on Ethereum’s base layer for security.
Fusaka contains 12 changes, known as Ethereum Improvement Proposals (EIPs). These upgrades target scalability by improving data availability and managing transaction verification more efficiently. One of the key innovations is PeerDAS, which reduces the data burden nodes face when validating layer 2 transactions.
Layer 2 chains bundle thousands of transactions into summaries called blobs, which are submitted to Ethereum’s base layer. Currently, nodes must download entire blobs to verify these transactions, creating significant data traffic and increased costs as volume grows. PeerDAS addresses this by allowing nodes to verify random samples within blobs instead of the full data, lowering bandwidth usage and verification expenses.
Described by Leo Fan, co-founder of zero-knowledge blockchain Cysic, as a “deep infrastructural shift,” Fusaka is expected to increase Ethereum’s throughput by up to eight times. Shiv Shankar, CEO of zero-knowledge scalability protocol Boundless, noted that these improvements will enable Ethereum to handle more activity, benefitting developers building decentralized applications.
Beyond layer 2 enhancements, Fusaka also includes changes to the base layer. Two EIPs increase block and data limits, allowing for higher transaction processing and more blobs from layer 2 chains. This upgrade follows the May rollout of the Pectra upgrade, continuing Ethereum’s roadmap to scale its network beyond its current 30 transactions per second capacity.
More details on Fusaka are available from the Ethereum Foundation announcement and layer 2 scaling information is summarized at L2Beat.
