TechFlow News, May 29: According to The Block, Coinbase’s Ethereum Layer 2 network Base 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 Trusted Execution Environment (TEE) proofs with zero-knowledge (ZK) proofs, reducing the minimum withdrawal finalization time to as little as 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, base-reth-node, and introduces a new consensus client, base-consensus, built upon 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.
