Peer Exchange

The primary objective of this protocol is to facilitate peer connectivity for resource-limited devices without relying on Discv5. The peer exchange protocol enables light nodes to request peers from other nodes within the network. Have a look at the Peer Exchange specification to learn more.

:::info Peer Exchange enables requesting random peers from other network nodes without revealing information about their connectivity or neighbourhood. :::

Pros

  • Low resource requirements.
  • Decentralised with random sampling of nodes from a global view using Discv5.

Cons

  • Decreased anonymity.
  • Imposes additional load on responder nodes.
