Base Launches Azul Mainnet Upgrade, Introducing a Multi-Proof System to Accelerate Decentralization
According to The Block, Base—the Ethereum Layer 2 network operated by Coinbase—has officially activated the Azul upgrade on its mainnet. This marks Base’s first independent network upgrade following its separation from the Optimism Superchain.
The Azul upgrade introduces a multi-proof system that combines TEE (Trusted Execution Environment) proofs with zero-knowledge (ZK) proofs, reducing the shortest possible withdrawal finalization time to just one day. Both proof types can independently confirm proposals; in case of conflict, permissionless ZK proofs override TEE proofs—further enhancing the network’s censorship resistance.
Additionally, Azul integrates Base into a single execution client, <code>base-reth-node</code>, and introduces a new consensus client, <code>base-consensus</code>, built on OP Kona. Following the upgrade, the number of empty blocks has plummeted from approximately 200 per day to roughly 2 per day, and the network has achieved a sustained peak throughput of 5,000 transactions per second.
