Base Azul Launches on Mainnet to Improve Speed and Security

According to Base, Azul is now live on mainnet with a TEE and ZK multi-proof system, about one-day withdrawal finality, and lower empty-block rates after Base’s first independent upgrade outside the Optimism Superchain.

OP

Fact Check
The official @buildonbase post announces Azul going live on mainnet with multiproofs and the new client stack. The Block and Crypto Briefing independently corroborate the same launch with details consistent with the claim (decentralization progress, performance, Stage 2 advancement).

Summary

Base activated the Azul upgrade on mainnet, introducing a multi-proof system that combines trusted execution environment (TEE) proofs with zero-knowledge proofs and can reduce withdrawal finality to about one day when the proofs agree. The launch marks Base’s first independent network upgrade after separating from the Optimism Superchain. Base said the upgrade also sharply reduced daily empty blocks from about 200 to about 2 and supported 5,000 transactions per second in stress tests. The existing Azul stack also includes a new client architecture intended to improve performance and support Base’s broader decentralization goals.

Terms & Concepts
  • zero-knowledge proofs: A cryptographic method that proves a claim is valid without revealing the underlying data, often used to improve blockchain scalability and verification.
  • trusted execution environment (TEE): A secure hardware-based environment that isolates computation and data, used in Base’s proof system alongside ZK proofs.
  • Optimism Superchain: A network framework of interoperable chains built on the OP Stack, from which Base said it separated before this independent upgrade.
