Node types and light protocol

Mazze supports multiple node types that trade storage for sync cost.

Node types

• Archive - keeps full historical state and receipts.

• Full - keeps recent state and snapshots, prunes older history.

• Light - relies on witnesses/blame verification and remote state proofs.

The node type is encoded on the wire and affects sync preferences.

Light protocol

The light protocol provides:

• Block/receipt proofs and witnesses for light clients.

• Peer type validation to avoid incompatible requests.

Light nodes are more conservative about which peers they accept and what data they trust, using the blame field and witness checks.
