TechFlow reports that the Delta hard fork has been deployed across various chains based on Optimism, including OP Mainnet, Base, and Zora.
This upgrade aims to reduce the fixed overhead costs of L1 fees and has achieved its intended results.
Span Batches, a key feature of the Delta upgrade, consolidate consecutive Layer 2 blocks into a single batch, reducing the amount of data posted to Ethereum. This is expected to cut L1 fees by 6% to 11%. Optimism is a Layer 2 chain ecosystem leveraging optimistic scaling to lower transaction costs for dapps.
