Coinbase's Ethereum Layer 2 Base Unveils Azul, Advancing Decentralization

Base has recently launched Azul on its mainnet, marking a significant step towards decentralization for Coinbase's Ethereum layer 2 solution.

This upgrade introduces a multiproof system that combines trusted execution environment proofs with zero-knowledge proofs, aimed at reducing centralization.

Both proof types can independently finalize a proposal, but when they align, withdrawal finality is expedited to as little as one day, enhancing efficiency.

Notably, permissionless ZK proofs can also override permissioned TEE proofs in case of discrepancies, thereby moving closer to censorship resistance.

Azul consolidates the network onto a single execution client and introduces base-consensus, the first independent upgrade executed by Base.

This new client stack has drastically reduced empty blocks by about 99%, improving throughput to handle up to 5,000 transactions per second.

Additionally, the upgrade includes the implementation of the CLZ opcode and aligns with Ethereum's Osaka execution-layer repricing, easing the transition for developers.

Base, now one of the most significant Ethereum scaling networks, has over $4.4 billion in total value locked and leads in USDC liquidity among optimistic rollups.

Looking ahead, two more upgrades are set for the second half of the year, focusing on performance and user experience enhancements, alongside native account abstraction.

As Base continues to evolve, it positions itself as a pivotal player in the Ethereum ecosystem.
