# Taiko x Nethermind: Building Ethereum-Aligned Based Rollup Infrastructure

By [Taiko Labs](https://paragraph.com/@taiko-labs), 2025-07-04

---

We’re excited to announce a strategic partnership with [**Nethermind**](https://x.com/nethermindeth), bringing together two teams deeply aligned on the vision of a decentralized, performant, and production-ready based rollup stack. This collaboration is grounded in a shared commitment to advancing the frontier of Layer 2 infrastructure with a clear focus on decentralization, sequencing innovation, and trust-minimized design. Together, we’re working to accelerate the evolution of the based rollup ecosystem, turning research into resilient, permissionless systems ready for mainnet.

**What we’re working on:**

· Preconfirmation infrastructure including PBS models, same-slot L1CALLs, and constraint APIs

· EIP-7917 implementation to support trust-minimized L2 sequencing

· ZK gas profiling and metering

· L2 fee mechanism design for composable, sustainable rollup economics

· Permissionless Mainnet-ready preconfirmation sidecars for production deployments

**From Research to Implementation**

This collaboration spans upstream protocol work, client integration, and open standards, all aimed at delivering mainnet-ready infrastructure with no compromise on decentralization. Together with Nethermind, we’re bringing critical systems into production and strengthening the based rollup ecosystem.

More to come.
