The Foundation of Network Trust

System-Level Keys:

The Foundation of Network Trust

Wallet keys move assets.
System-level keys protect the network itself.

In Canton, security isn’t just about asset custody. It’s about trust in every node, every transaction, and every rule embedded in the system.

System-level keys power encrypted state sharing, consensus, and operational logic. When they’re mismanaged, the entire environment is exposed.

Why It Matters

Trust Foundation

Institutions rely on infrastructure trust—not just user endpoints.

System Fragility

One compromised system key can unravel the entire node.

Controlled Continuity

Standardized key control ensures compliance, auditability, and continuity.

Overlooked Risk

Real security means managing what most others overlook.

The Hidden Risk: Node Keys

Real-world breaches rarely involve wallet hacks. They start with overlooked system-level keys.

Case in Point

GitHub Token Leak

An old token exposed 270GB of critical source code—including deployment scripts and infrastructure configs. Not a wallet key. A forgotten infrastructure credential.
