Delta hard fork slashes Layer 1 fees across Optimism chains by up to 90%. Introduction of Span Batches consolidates Layer 2 blocks, reducing data transmission. OP Labs aims to ease the adoption of OP Stack by alleviating fee burdens for operators.

Last week, the Optimism ecosystem witnessed a transformative shift with the deployment of the Delta hard fork across various chains, including OP Mainnet, Base, and Zora.

This technical upgrade, designed to slash Layer 1 fees, has surpassed expectations, marking a significant milestone for Optimism and its community.

The Delta hard fork, spearheaded by OP Labs, the core developer behind Optimism, showcased remarkable efficacy in reducing fixed overhead costs associated with Layer 1 fees. Zora-sepolia’s data revealed a staggering 90% decrease in costs, leading to a substantial boost in revenue collection by Zora.

The key driver behind this achievement is the introduction of Span Batches, a pivotal feature embedded in the Delta upgrade. This innovative addition allows the consolidation of consecutive Layer 2 blocks into a single batch, significantly reducing the volume of data transmitted to Ethereum.

Developed by Test in Prod with initial contributions from researcher Protolambda, Span Batches delivered on its promise, slashing L1 fees by 6% to 11% for more active chains and exceeding 90% for less active ones.

Optimism, with its Superchain comprising Layer 2 chains utilizing optimistic rollups, has positioned itself as a frontrunner in reducing transaction costs for decentralized applications (dapps). Governed by the Optimism Collective, this ecosystem has now received a formidable boost from the Delta hard fork.

The Delta hard fork is not merely a technological upgrade but a strategic move to make the adoption of the OP Stack more accessible by alleviating fee burdens for all chain operators.

OP Labs expresses confidence in a blog post that this enhancement will ease the integration of the OP Stack, fostering a more seamless experience for operators within the Optimism ecosystem.

As the Superchain continues to evolve and adapt, the Delta hard fork’s resounding success echoes a promising future for Optimism.

The reduction in fixed overhead costs not only enhances the economic viability of the ecosystem but also positions Optimism as a leader in addressing the scalability challenges faced by blockchain networks.
