Node Design

PenguChain nodes are read-replica instances derived from the main sequencer node. They replay historical state, expose RPC endpoints, and serve data to products and APIs. These nodes are not consensus participants and do not generate blocks or proofs themselves.

• Sequencer Node: Internally operated. Handles block production, batching, and L1 submissions.

• Replica Nodes: Read-only nodes used for data access, indexing, and monitoring.

• Proof Infrastructure: Validity proofs are generated off-chain and submitted by internal systems.

This design ensures predictable performance while maintaining integrity through on-chain proof verification.
