ONE CHIP. THE WHOLE PICTURE.01 / 05
Identity is the starting point.
One foundation. Different possibilities.

Built from
the inside out.

Follow the chip. From the wallet foundation to the number you use every day.

Build on the foundation ↗

The chip is a visual guide to the software architecture. LightPBX is a connected service; SecNum sits inside the Arnacon app. Applications supply their own interface and call-media implementation.

Identity comes first.

Reach an identity without making a phone number the starting point.

Build beyond one app.

The protocol and integration layer support different experiences and service providers.

Open by direction.

Decentralized identity and configurable routing, with practical connections to today’s networks.
