Linea's Open-Source Move Is Progress — But the Network Is Still Centralized
-

While Linea Consortium's decision to open-source its ZK rollup stack under Linux Foundation governance is a meaningful step, it's important to understand what the move does and doesn't change. The contribution affects the governance of Linea's open-source technology code, not the operational structure of the Linea network itself. Key components of the live network — including its sequencer, prover, upgrade controls, and validator participation — remain centralized and are still maintained by the core team. Linea's own risk disclosures confirm that its Mainnet Beta includes centralized components, and that the sequencer retains the ability to postpone or reorder transactions.L2Beat, the leading analytics tracker for Ethereum layer-2 networks, currently classifies Linea as a Stage 0 rollup — the lowest tier, reserved for networks that still rely heavily on trusted operators rather than permissionless smart contract mechanisms. This places Linea far from Stage 2, the benchmark Ethereum co-founder Vitalik Buterin has set for L2 networks that are mostly governed by code rather than teams. Buterin himself acknowledged in February that progress toward Stage 2 across the L2 ecosystem has been "slower and harder than expected." Linea's open-source governance move may lay important groundwork, but full decentralization of the network remains a work in progress.
