#What is the significance of Azul’s launch?
Coinbase’s Ethereum Layer 2 network Base has debuted its first independent network upgrade named Azul on May 13. This upgrade follows the successful testnet activation in late April and signifies a substantial step forward for Base. By moving from the shared Optimism tech stack to a private engineering infrastructure, Base is establishing its own technological identity.
#How does Azul enhance transaction security?
Azul introduces a multiproof security system that utilizes two different verification technologies: Trusted Execution Environment and zero-knowledge proofs. This dual verification mechanism operates simultaneously, ensuring that transactions are validated through independent checks. As a result, if both systems verify a transaction's validity, users can expect withdrawals to be processed in as few as 24 hours. This is a notable reduction compared to the typical seven-day waiting period common with many optimistic rollups.
During testing before the launch, the network demonstrated the ability to handle spikes of up to 5,000 transactions per second. Additionally, the frequency of empty blocks significantly decreased from about 200 daily to roughly 2, indicating a more efficient network performance.
#What steps were taken before the launch?
The groundwork for Azul began with a testnet launch around April 21-22. This platform allowed developers and node operators ample time to troubleshoot issues before the actual network upgrade. Rigorous security audits were conducted, and a bug bounty program worth $250,000 was set up via Immunefi to encourage vulnerability reporting from April 21 to May 4.
Node operators were required to switch to Base-native clients, specifically base-reth-node and base-consensus. This transition was mandatory rather than optional. For users, the switch was designed to be seamless, requiring no wallet alterations or service interruptions.
Furthermore, the update aligns Base with Ethereum’s Osaka specifications, with an ambitious throughput target of 1 gigagas per second.
#Why is Azul important to the Layer 2 ecosystem?
Azul’s innovative multiproof system directly tackles a major criticism associated with optimistic rollups: prolonged withdrawal periods. By effectively combining Trusted Execution Environment and zero-knowledge proofs, Base can provide quicker transaction finality while maintaining robust security standards.
The implementation of this hybrid approach is relatively unique in the industry. Although thorough audits and a bug bounty program are in place to mitigate risks, early adopters of novel security systems should be aware of potential uncertainties in the initial months of operation.
