Problem this solves: Teams sometimes don’t know what components a validator runs or how they fit together—leading to misconfigured testnets or wrong performance expectations.

What you’ll learn:

The internal modules of a Sui validator

How networking, consensus, and execution coordinate

Monitoring key metrics

1. Core components

Narwhal worker: Handles incoming tx batches.

Narwhal primary: Builds DAG, coordinates with other validators.

Bullshark engine: Orders transactions when required.

Execution engine: Runs Move VM on valid transactions.

Storage subsystem: Manages persistent data.

2. Key metrics to watch

Transaction throughput (TPS)

Latency per category (owned vs shared)

CPU usage per module

Storage I/O

3. Deployment note

Separate networking-heavy and execution-heavy workloads onto different hardware if scaling.
