libp2p ACL (Certificate Authority)

Does libP2P support CA(Certificate Authority)?(For example, I want to use libP2P to create a coalition that requires an access mechanism to enter)

Libp2p does not support the CA system, but you can limit access to a swarm:

  1. You can configure a pre-shared key (, limiting access to those with the same pre-shared key.
  2. You can implement a connection “gater” ( that filters peers by peer ID (assuming you have some list of allowed peer IDs).
