Coinbase-incubated Ethereum Layer 2 network Base is planning a core architecture upgrade. The network says it will move from optimistic rollups to a zero-knowledge-based system that combines a trusted execution environment (TEE) with zero-knowledge proofs.
Base also links the upgrade to using Succinct Labs’ SP1. In the project’s framing, SP1 is an open-source zkVM that can generate succinct ZK proofs for arbitrary computation written in Rust. Base says SP1 is designed to let rollups, apps, and bridges add ZK-based security without building proprietary proving infrastructure.
Why it matters
Base says this shift changes its security model. The company claims the move removes the multi-day challenge period typical of optimistic rollups and replaces it with cryptographic finality, which it describes as aiming at one-day finality.
Base also positions the change as “trust-minimized” for large capital movements back to Ethereum mainnet. It further claims it will become the largest single Ethereum operator implementing ZK proofs for finality, according to an official press release shared with CryptoPotato.
Wilson Cussak, Head of Base Chain, is quoted saying the ZK proofs upgrade is meant to strengthen the infrastructure Base users and developers rely on.
Market impact
Base says the upgrade should extend across much of the Ethereum L2 ecosystem, at least by its own expectations. It frames the post-mainnet deployment outcome as most of the Ethereum Layer 2 ecosystem, measured by total value locked, daily users, and transaction throughput, being secured through a TEE supported by ZK proofs generated with SP1.
In parallel, Base has faced community criticism over how assets gain traction on the network. Jesse Pollak, Base co-founder, responded by saying the team does not and will not engage in price manipulation or privately coordinate to push any asset toward a specific outcome. He also said such behavior would disadvantage other projects, conflict with open market principles, and could be illegal. Pollak adds that Base will focus on improving distribution and visibility for high-quality applications, while acknowledging room to improve attraction of capital and attention.

| Finality timeline goal | Aim to cut out multi-day challenge period and target one-day finality | Base via provided text |
| Proving tech | Zero-knowledge proofs via Succinct Labs SP1 zkVM | Base via provided text |
| Ecosystem impact (expected) | Most Ethereum L2 TVL, daily users, and throughput secured through TEE with ZK proofs | Base via provided text |
| Total capital (current) | Around $12 billion in total capital | Base via provided text |
What to watch next
Two things stand out for follow-up. First, Base’s mainnet deployment of the TEE plus ZK proofs flow and how it performs against the optimistic rollup challenge period it aims to remove. Second, the ongoing response to traction and coordination concerns. Pollak’s denial addresses manipulation, but the community’s focus will likely remain on how distribution and visibility work in practice.
The upgrade also aligns with views previously attributed to Vitalik Buterin in the provided text. Buterin is described as calling ZK-EVMs an Ethereum block validation “endgame,” with an expectation that such systems could become dominant proving methods between 2027 and 2030.
