What an announce carries
What an announce carries
An announce is a signed special packet that shares destination hash and public key information so others can build an outgoing destination. Application-specific data may be included. Aspect names are usually omitted to save bandwidth.
- Destination hash and public key material
- Optional application-specific data
- A random blob so successive announces are unique
- Ed25519 signature over the announce contents
Origin
Signed announce
Transport hop 1
Record sender, hop count
Transport hop 2
Retransmit after delay
…
Stop near m = 128
Transport nodes forward announces hop by hop, stopping after m + 1 retransmissions (default m = 128).
Send a plain announce, then one with app data
import RNS
# After creating a SINGLE destination as in the Minimal example:
destination.announce()
# Optional application bytes travel with the signed announce.
destination.announce(app_data=b"hello-mesh")
Selbst ausprobieren: Step through the flood. Watch how neighbors learn a next hop without learning a full route map.
Hop 0
Origin signs announce (hash, public key, optional app data, random blob).
