On May 28, 2026, at 18:00 UTC, Base activated the Azul network upgrade on its mainnet . This is the chain's first independent protocol upgrade, built entirely outside the OP Stack, and it represents a significant stride toward Stage 2 decentralization. The upgrade activates a multiproof architecture, unifies the client stack, and adopts the latest Ethereum execution-layer specification.
How the Multiproof Architecture Works
At the core of Azul is a dual-proof system that couples trusted execution environment (TEE) proofs with zero-knowledge (ZK) proofs into a single security framework .

What should I do next in practice?
This is Base's first independent protocol upgrade outside the OP Stack, aligning the network with Ethereum's Osaka specification and advancing it toward Stage 2 decentralization.
Either proof type can independently finalize a block proposal, creating redundancy that eliminates single points of failure. The critical breakthrough for users, however, is what happens when both proof systems agree on the same result.
Under the previous OP Stack-based design, withdrawing assets from Base back to Ethereum mainnet required waiting through a seven-day challenge window. With Azul, when a ZK proof—generated by SP1—and a TEE proof back the same proposal, withdrawal finality drops to as little as one day . This dramatically improves capital efficiency for users moving assets between chains.
The architecture also includes a safety override. ZK proofs override TEE proofs if the two systems produce conflicting results. Any contradiction automatically triggers a soundness alert that disables the associated prover, ensuring the chain can detect and handle proof system bugs onchain without relying on a privileged security council . This onchain fault-detection capability is a core technical requirement for Stage 2 decentralization.
A Unified Client Stack and 99% Fewer Empty Blocks
Azul consolidates Base onto a single execution client—base-reth-node—paired with a single consensus client, base-consensus. Nodes running legacy OP Stack clients such as op-geth, op-reth, nethermind, or kona no longer support the network and required migration before activation . This unified approach simplifies node operations and improves performance.
Performance gains were visible even before mainnet activation. Over the two months leading up to launch, the Base network reduced the number of empty blocks by approximately 99%, from an average of roughly 200 per day to about two per day . During the same period, the network sustained multiple bursts of 5,000 transactions per second .
Alignment with Ethereum's Osaka Specification
The upgrade also aligns Base with Ethereum's latest execution-layer specification, Osaka, including EIP-7825, which introduces a per-transaction gas cap of approximately 17 million gas . This keeps Base compatible with Ethereum's evolving standards while it continues to operate as an independent Layer 2.
A Meaningful Step Toward Stage 2 Decentralization
The Azul upgrade is more than a performance improvement. By activating multiproofs and adopting a fully independent client stack, Base has taken its biggest single step toward Stage 2 decentralization. The ability to detect proof-system faults onchain without a security council intervention, combined with faster withdrawal finality and a simplified node architecture, positions Base to compete more aggressively in the Layer 2 landscape.
