“Optimism Ecosystem Chains See 90% Fee Reductions After Successful Delta Hard Fork”


The Optimism ecosystem recently experienced a significant shift with the deployment of the Delta hard fork across various chains, including OP Mainnet, Base, and Zora. This upgrade, led by OP Labs, aims to slash Layer 1 fees and has surpassed expectations, marking a milestone for the community.

With the introduction of Span Batches, a feature embedded in the Delta upgrade, consecutive Layer 2 blocks can now be consolidated into a single batch, reducing the volume of data transmitted to Ethereum. As a result, fixed overhead costs associated with Layer 1 fees have decreased by up to 90%.

Zora-sepolia’s data reveals a remarkable decrease in fees, leading to a substantial increase in revenue collection. The success of Span Batches has been attributed to its development by Test in Prod and initial contributions from researcher Protolambda.

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

The Delta upgrade not only serves as a technological enhancement but also strategically aims to make the adoption of the OP Stack more accessible by alleviating fee burdens for all chain operators. OP Labs expresses confidence that this improvement will ease the integration of the OP Stack, providing a seamless experience for operators within the Optimism ecosystem.

As the Superchain continues to evolve, the success of the Delta hard fork has bolstered the future of Optimism. This reduction in fixed overhead costs not only enhances the economic viability of the ecosystem but also positions Optimism as a leader in addressing scalability challenges faced by blockchain networks.
