Unfolded reported that Coinbase-incubated Layer 2 Base has launched its first upgrade, Azul, on the testnet. The core of this upgrade is the Multiproofs system, which adopts a hybrid approach combining TEE (Trusted Execution Environment) and ZK (Zero-Knowledge) proofs. Block finalization is possible with just one of the two proof methods, and if the results of both methods match, the current 7-day withdrawal waiting period can be significantly shortened to just 1 day.
