The Hypergraph
Constellation isn't a blockchain — it's a Hypergraph. Instead of one chain of blocks, data is organized as a DAG (Directed Acyclic Graph), letting many parts of the network process in parallel. That's how it scales horizontally and stays feeless for users.
Layer 0 — the backbone
The Global L0 is the security and settlement layer. The ~160 validators forming the shell around the core run PRO consensus to bundle activity into global snapshots — the live stream along the bottom. Each snapshot references the previous one, forming the DAG.
Layer 1 — transactions & data
L1 nodes accept transactions and application data, validate them, and feed them up into L0 to be finalized. Separating L1 from L0 means apps can move fast without bloating the secure base layer.
Metagraphs — networks of their own
The orbiting clusters are metagraphs: independent, customizable networks (their own L0 + L1) that anchor their state into the Global L0 for security. Each can have its own token, rules and data — yet they all share the Hypergraph's trust.
