How does AggLayer handle proof aggregation across rollups?
I'm diving into the technicalities of AggLayer and its handling of proof aggregation. Specifically, does AggLayer function as a zk rollup chain itself, and how does it aggregate proofs from different rollup chains? Are these proofs merely treated as normal transaction data, or is there an aggregation proof algorithm employed, like Halo, Plonky2, or Nova? Additionally, how do rollup chain nodes verify these aggregated proofs—does this involve a contract deployed on Ethereum?

2AggLayer isn't a rollup chain; it acts as a layer for aggregating proofs from various rollup chains. These proofs, representing state transitions, are collected from different chains. However, further details about the specific proof aggregation methods and verification mechanisms might be best elaborated by someone more knowledgeable in this project, such as the tagged expert in the conversation.
The process involves handling proofs as representations of state transitions from various rollup chains. For comprehensive insight into the exact algorithms or contract deployments used for verification, feedback from a developer directly involved in AggLayer's implementation would be invaluable.
