midnight-node:node-architecture

What problem does it solve?

This Skill provides a clear, actionable explanation of how a Midnight Substrate-based node is organized and operates so developers and operators can debug, audit, and integrate nodes with Cardano and adjacent services without reading scattered design notes.

Core Features & Use Cases

• Runtime layout and pallets: Describes the node, runtime, pallets (system, consensus, midnight-specific, partner-chain bridge) and where on-chain logic lives.
• Consensus & finality: Explains AURA block production, GRANDPA finality, BEEFY bridge proofs, and MMR usage for light clients.
• Ledger, storage & transaction flow: Details ParityDB-backed ledger storage, ZK-proof verification, transaction pool filtering, throttle pallet, and the lifecycle from RPC submission to state update.
• Cardano integration: Covers db-sync/PostgreSQL follower architecture, cNIGHT bridging constraints, validator rotation, and governance sync scenarios.
• Use case: Use this Skill to onboard new node operators, troubleshoot block production/finality issues, or prepare a security/design review of cross-chain bridge behavior.

Quick Start

Ask the skill to explain how the Midnight node produces blocks, list the runtime pallets involved, and describe the transaction flow and Cardano bridging points.
