 Vac is a **modular peer-to-peer messaging stack, with a focus on secure messaging**. What does that mean? Let's unpack it a bit.

 Discovery in p2p networks is the process of how nodes find each other and specific resources they are looking for. Popular discovery protocols, such as [Kademlia](https://pdos.csail.mit.edu/~petar/papers/maymounkov-kademlia-lncs.pdf) which utilizes a [distributed hash table](https://en.wikipedia.org/wiki/Distributed_hash_table) or DHT, are highly inefficient for resource restricted devices. These methods use short connection windows, and it is quite battery intensive to keep establishing connections. Additionally, we cannot expect a mobile phone for example to synchronize an entire DHT using cellular data.
