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.
