Base Introduces Multiproofs With Azul Upgrade
Base's first standalone upgrade since leaving the Superchain introduces multiproofs combining TEE and ZK, plus a new client stack built on OP Kona.
Base announced the Azul upgrade, its first standalone network upgrade since departing Optimism's Superchain. The upgrade introduces multiproofs, enhancing security, decentralization, performance, and the overall developer experience. By combining Trusted Execution Environments (TEE) with zero-knowledge (ZK) proving, multiproofs move Base closer to Stage 2 decentralization.
Azul also streamlines the network architecture by consolidating operations onto a single execution client, base-reth-node, alongside a new consensus client, base-consensus, built on OP Kona. The upgrade is already running on testnet, with mainnet activation set for May 13, 2026. Node operators will need to transition to the new client stack ahead of that date.
Base is currently hosting a $250,000 audit competition on Immunefi running through May 4. Looking ahead, the team plans to introduce an enshrined token standard and Flashblock access lists by the end of June, followed by native account abstraction by the end of August.

Optimism Launches Privacy Boost
A plug-and-play SDK for adding confidentiality to any OP Stack chain, combining zero-knowledge proofs with trusted execution environments.
OP Labs introduced Privacy Boost, an SDK for adding confidentiality to any OP Stack chain. The release aims to help projects meet regulatory requirements such as MiCA, BSA, AML/KYC, and GDPR, which are difficult to satisfy when user transaction data is published on a public blockchain.
Privacy Boost combines zero-knowledge proofs with trusted execution environments, where ZK proofs ensure privacy and cryptographic integrity, while TEEs improve performance and simplify integration. Built on a UTXO-based model, the solution can generate proofs in under 500 milliseconds and includes a forced withdrawal feature. Privacy Boost is now live on OP Mainnet.
