Base Azul Launches on Mainnet to Improve Speed and Security

According to Base, Azul is now live on mainnet as the network’s first upgrade on its custom stack, combining TEE and zero-knowledge proofs to strengthen decentralization, speed, and security.

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 said it executed the Azul upgrade on mainnet, marking the first network upgrade on its custom stack. The Coinbase-backed Ethereum Layer-2 said Azul combines trusted execution environment (TEE) proofs with zero-knowledge proofs to improve decentralization, speed, and security. Base announced the mainnet upgrade on X on the 29th. Earlier details from Base said Azul’s multi-proof system can reduce withdrawal finality to about one day when TEE and ZK proofs agree, while the upgrade also lowered daily empty blocks from about 200 to about 2 and supported 5,000 transactions per second in stress tests.

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.
  • Ethereum Layer-2: A scaling network built on top of Ethereum that processes transactions more efficiently while relying on Ethereum for security and settlement.
