Cryptography

The Nym Network relies on several cryptographic systems working together. This section covers the algorithms, packet formats, and credential systems that provide privacy guarantees.

What's covered

Sphinx Packets explains the packet format that enables layered encryption and anonymous routing. Each Sphinx packet contains routing information encrypted in layers, where each hop can only decrypt its own layer.

zk-nyms covers the anonymous credential system that separates payment from usage. This is how you can pay for network access without that payment being linkable to your activity.
