Automata Network, as an R&D partner and infrastructure provider, has developed a set of Open Source Source Code for Espresso that runs within the trusted execution environment (TEE), specifically for the integration process of Arbitrum Nitro.

The core of this technical solution lies in directly deploying the rollup's batch poster into the TEE environment, thereby addressing the issue of centralization. TEE can create an isolated secure execution space, making the batch posting process more transparent and verifiable while maintaining the original performance advantages.

This integration approach is quite interesting - it utilizes the security features of TEE while ensuring the decentralized attributes of the rollup infrastructure. For L2 projects looking to enhance the credibility of sequencers, it provides a practical reference solution.
