Fault tolerance and network dynamics
Kadcast is inherently resilient to network changes and failures due to its reliance on
Kademlia’s DHT. In highly dynamic networks where nodes frequently join and leave,
Kadcast ensures that message propagation remains robust. Nodes can dynamically
update their routing tables by removing failed peers and replacing them with new
ones. This constant re-evaluation and updating of routing tables allow Kadcast to
maintain high availability and fault tolerance.
Additionally, the use of multiple peers within buckets means that if one node fails
to forward a message, alternative paths can be used, ensuring that the message still
reaches its intended recipients. This fault tolerance makes Kadcast particularly suit-
able for decentralized environments, where network conditions can be unpredictable,
and nodes may be offline or unreliable.
2.3 Security and privacy
To mitigate the risk of malicious behavior such as Sybil attacks, Kadcast uses various
mechanisms for validating message authenticity and ensuring that nodes cannot easily
disrupt message propagation. In paritcular, messages are signed, and nodes verify
the signatures before forwarding them, $DUSK
