Network ADDN AI-Powered Decentralized Distribution Network

An AI-native network with no central core to fail.

ADDN is the AI-Powered Decentralized Distribution Network — an industry-first, independently deployable travel and payment infrastructure that replaces the centralized GDS core. It runs across independent hubs, each carrying the full system on its own.

How the network works

Decentralized & autonomous

Each hub runs the full system on its own — no central server, no master hub.

Shares only what's needed

Hubs exchange only what a booking needs — never bulk data — so it stays in its home region.

Resilient by design

If one hub goes offline, the rest keep running — no single system failure can take it all down.

Scale on demand

Add a hub in any new region or country — it joins automatically, with no central rebuild.

Live network · online today

Three live hubs. More on demand.

The network is live across three hubs today, carrying FCG's full supply — and any new region or country can join on demand, with no central rebuild.

Hub · SG

Singapore

Regional hub — autonomous and resilient, exchanging only what a booking needs across the network.

Hub · CN

China · Wuhan

China hub — keeps China data in its home region while serving two-way, in-and-out-of-China travel.

Expansion-ready

Add any region

A new country or regional hub joins on demand — extending coverage, capacity, and data residency automatically.

Layers of the stack

The layer everything else sits on.

Booking front-ends, operating systems, and developer APIs all run on the same foundation. ADDN is the network layer underneath the whole stack.

Decentralized & autonomous

Each hub runs the full system on its own — no central server, no master hub.

Data stays in region

Hubs exchange only what a booking needs — never bulk data — so it stays in its home region.

Resilient by design

If one hub goes offline, the rest keep running — no single point of failure.

Scale on demand

Add a hub in any new region or country and it joins automatically — no central rebuild.
