The open-source ZK rollup stack that has powered Linea Mainnet since 2023 is being contributed to Linux Foundation Decentralized Trust as a new incubating project: Lineth. The Linea Consortium is joining LFDT as a premier member, taking a seat on the Governing Board alongside DTCC, Hedera, Kaleido, OpenAssets, Shielded Technologies and Consensys, which already holds a board seat through Rob Dawson. From this point forward, the technology that secures Linea – and that institutions can deploy for their own networks – lives in a vendor-neutral home that no single company controls.

Open source was the first step. Open governance is the step that matters.

Linea Stack has been open source from day one. What changes today is the governance of technology: a transparent, multi-stakeholder framework that no single company can override, redirect, or walk away from.

This distinction matters because open governance is what makes open-source code usable in regulated production. Institutions and Enterprises building onchain need to know that the rules of the infrastructure are not subject to a single vendor’s strategic priorities, financial situation, or change of direction. They need the confidence to commit to this stack on a decade-long horizon.

A foundation that institutions already trust

The Linux Foundation has spent twenty-five years hosting the infrastructure that the world’s institutions actually run on. Linux, Kubernetes, Besu among others – and now Lineth.

The pattern is visible far outside crypto. In April 2026, the French government – through DINUM – ordered every ministry to plan a migration from Windows to Linux, citing digital sovereignty and the need to control its own infrastructure. The Gendarmerie nationale has run Linux on more than 100,000 workstations since 2008, with documented savings and a 40% reduction in total cost of ownership. When governments and large institutions look for infrastructure they can commit to for decades, the Linux Foundation is the address they go to. 

It is not a coincidence that the systems hosted there tend to outlive the companies that contributed them. Lineth now lives there. 

Extending Ethereum’s strengths to the Enterprise

Institutions need two things at once, and they are usually told to choose. They need the innovation of Ethereum: the developer ecosystem, composability, the talent pool, the standards and access to global liquidity. They also need the stability of enterprise infrastructure: predictable governance, license guarantees, vendor neutrality, an audit trail their architecture review boards will accept.

The two are usually framed as a trade-off. They should not be.

Lineth is built to bring these two together. By taking the production stack that already secures Linea Mainnet and placing it under LFDT – alongside Besu, the Ethereum execution client that Lineth runs on – we extend Ethereum’s open ecosystem with the governance guarantees institutions need to deploy at scale. Innovation and stability under the same neutral foundation, building on what Ethereum has spent a decade getting right.

The stack already secures Linea Mainnet

What is being contributed to LFDT is a production infrastructure with a track record:

Since July 2023:

• 300M+ transactions finalized to Ethereum

• 416k zero-knowledge proofs generated and verified on L1

• 99.98% sequencer uptime over the past twelve months

• Up to $2.5B TVL secured at peak

• Audited by OpenZeppelin, Diligence, and Cyfrin

Consensys has done this before. Besu was incubated at Consensys, and contributed to LFDT, where it became the most widely adopted enterprise Ethereum client. Linea is the same playbook, now applied to Layer 2.

“Consensys and the global community of Besu maintainers have already shown what is possible when critical Ethereum infrastructure is developed under open source and open governance,” said Daniela Barbosa, General Manager, Decentralized Technologies, Linux Foundation, and Executive Director, LF Decentralized Trust. “Besu was contributed to the Linux Foundation in 2019 and has grown into one of the most widely adopted EVM protocols in the world, running as one the top execution clients for Ethereum mainnet and powering Linea and major enterprise deployments worldwide. .  With Lineth, we are extending that same model to Layer 2 infrastructure. This is a major step toward credible, neutral infrastructure that developers, enterprises, and institutions can rely on for the long term. Open source was the first step. Open governance in a neutral foundation is what makes it durable and less risky for institutions.” 

Infrastructure this foundational should belong to everyone who builds on it. That’s what makes it a public good. That’s what makes it last, and what makes it trusted. 

Some infrastructure is meant to be owned. Other infrastructure is meant to last. Lineth is the second kind.
